- Oracle JDBC Drivers release 9.2.0 README
- =============================================
- What Is New In This Release Since 9.0.2 ?
- -----------------------------------------
- New classes file name for JDK 1.4 and beyond
- Beginning with this release the classes files for JDK 1.4 and
- beyond will be named ojdbc<jdk ver>.jar. So, the classes file for
- JDK 1.4 is named ojdbc14.jar. The names for the JDK 1.1
- and 1.2 classes files will not be changed. We will not provide
- .zip versions of the classes files beyond JDK 1.2.
- Direct support for LOBs in the Thin driver.
- The Thin driver now provides direct support for BFILEs, BLOBs, and
- CLOBs. Prior to this release it supported them via calls to PL/SQL
- routines.
- Statement Caching
- The Oracle statement caching API has been changed. There were
- substantial problems with the previous API and we were able to
- resolve them only by changing the API. The old API is still
- supported, but is deprecated. For details on the new API see the
- JavaDoc.
- Certified with RAC
- The Oracle JDBC drivers are certified to work correctly in an
- Oracle 9i RAC environment.
- JDBC 3.0 feature support
- A few critical JDBC 3.0 features are supported.
- JDK 1.4--JDK 1.4 is supported with ojdbc14.jar and
- nls_charset12.jar.
- Toggling between global and local transactions--When using an XA
- connection an application can toggle between global and local
- transactions.
- Savepoints--Savepoints are supported in ojdbc14.jar. They are also
- supported in classes12 and classes11 via Oracle extensions. The
- extensions are forward compatible with ojdbc14.jar. See the
- JavaDoc for more details.
- Reuse of prepared statements--PreparedStatements can be used with
- different pooled connections. This is an important performance
- improvement for middle tier applications.
- Connection wrapping
- It is now possible to seamlessly wrap an OracleConnection instance
- with a user defined class that implements
- oracle.jdbc.OracleConnection. Such a wrapper can be used where
- ever a Connection argument is needed (except CustomDatum) and will
- be returned as the value of getConnection. It is recommended that
- users subclass oracle.jdbc.OracleConnectionWrapper if
- possible. If not then base your implementation on the source for
- OracleConnectionWrapper which can be found in the samples
- directory.
- Deprecate RAW(Object) constructor
- The constructor RAW(Object) has been deprecated. It will not be
- removed, but its behavior will be changed in the next major
- release. At present it has a documented, but anomolous behavior
- when passed a String object. It constructs a RAW containing the
- byte representation of the String in the platform encoding. All
- other transformations between Strings and RAWs assume that the
- String is the hex character representation of the bytes in the
- RAW. In the next major release this constructor will be changed to
- conform to that convention. This will also impact ADTs with RAW
- fields constructed from Strings. Two static methods have been
- added to RAW. oldRAW(Object) will always have the current platform
- encoding behavior. newRAW(Object) will always have the hex
- character behavior. See the JavaDoc for more details.
- DMS metrics
- The DMS metrics reported by JDBC when using classes12dms.jar have
- been reorganized. Additional metrics on Statements including
- execution and fetch time are reported.
- defineColumnType(int, int) of CHAR or VARCHAR column
- Calling defineColumnType as CHAR or VARCHAR and not passing a size
- will now raise a SQLWarining. Beginning in the next major release
- it will throw a SQLException.
- OracleLog
- Significant increase in the number of methods that include calls
- to OracleLog. Also, you can enable OracleLog tracing by setting
- system properties. Set oracle.jdbc.Trace to "true" to enable
- tracing. Set oracle.jdbc.LogFile to set the name of the trace
- output file. If this is not set trace output is sent to
- System.out. OracleLog tracing is only available in the debug
- classes files, classes111_g.*, classes12_g.*, and ojdbc_g.jar.
- Support for services in URLs
- Oracle is replacing the SID mechanism for identifying databases
- with a new services approach. This has been available in the
- database since 8.1.7. JDBC now supports services in the connect
- URL for the Thin driver. We strongly encourage everyone to
- transition from SIDs to services as quickly as possible as SIDs
- will be cease to be supported in one of the next few releases of
- the database.
- The basic format of a service URL is:
- jdbc:oracle:thin:[<user>/<password>]@//<host>[:<port>]/<service>
- Example:
- jdbc:oracle:thin:@//myserver.com/customer_db
- For more info see the JDBC User Guide.
- Major bugs fixed in since 9.0.2:
- --------------------------------
- BUG-1324918
- The JDBC OCI driver can consume temporary tablespace when it is
- used to update a CLOB with PreparedStatement.setCharacterStream()
- repeatedly. In such situation, either the temp tablespace will
- continue to grow, or you may get this exception in thread "main":
- java.sql.SQLException: ORA-01652: unable to extend segment if
- you have a limit on the tablespace size. The workaround is to
- use oracle.sql.CLOB::setCharacterOutputStream() instead.
- BUG-1591421 (since 9.0.0)
- A connection created from the connection cache fails to pass the
- default batch value to the statement object.
- BUG-1630414 (since 9.0.0)
- After a type evolution is performed on an existing type, objects
- of the evolved type cannot be retrieved via JDBC.
- BUG-1730903 (since 9.0.0)
- setFormOfUse() method must be put before blinding/definding SQL
- NCHAR datatypes. For example, setString() and
- registerOutParameter() has to be called after setFormOfUse().
- Otherwise, unpredictable results will be received. This
- restriction applies to all JDBC drivers.
- BUG-1714281 (since 9.0.1)
- The maximum number of characters can be inserted into NCHAR
- datatypes using setString() is less than the database maximum
- size if the database character set is neither US7ASCII nor
- WE8ISO8859P1. This restriction applies to JDBC Thin and Thin
- Server-side drivers. Workaround is to use setCharacterStream().
- BUG-1720657 ( since 9.0.1)
- Java code runing on the server which uses the KPRB driver to execute
- multiple create type statements may cause server crashes. Similar
- problems exist if a PL/SQL block uses execute immediate to execute
- the same statements. The workaround is to use the thin driver or to
- perform the needed operations another way.
- Bug-2100396
- transaction isolation level is not reset when using JDBC api
- Bug-2100385
- JDBC cache does not handle inactivity timeout for xaconnections
- Bug-2100350
- JDBC cache does not work for inactivity timeout
- Bug-2018316
- getConnection should ignore case for user/passwd, setCache should
- take string
- Bug-2013416
- JDBC connection cache does not have any timeouts
- BUG 1868371 - setCHAR() does not convert from the CHAR object's
- charset to the db char set This JDBC limitation since 8.1.6 is
- removed in 9iR2. Previously constructing a Oracle.sql.CHAR data
- type with the following statement requires to use either UTF8,
- US7ASCII or WE8ISO8859P1 in the "char set" part for database SQL
- CHAR datatypes (limitation did apply to database object and SQL
- NCHAR datatypes) stmt.setCHAR(1, new CHAR(<bytes>, <char set>);
- BUG 1730903 - data corruption with setFormOfUse() after
- registerOutParameter(). This JDBC limitation since 9.0.1 is removed
- in 9iR2
- BUG 1714281 - SQLException with setString() of a long string to
- SQL NCHAR datatypes This THIN driver specific limitation since
- 9.0.1 is removed in 9iR2. setString() can now blind the same size
- of data as in database for SQL NCHAR datatypes
- BUG 2012717 - AVOID THE RESETTING OF NLS_LANG IN JDBC-OCI DRIVER
- Since 7.3.4, JDBC-OCI driver reset NLS_LANG internally to ".UTF8"
- when the client character set is neither US7ASCII nor
- WE8ISO8859P1. This means that in a child process fork out from
- JDBC-OCI, UTF8 data is returned no matter what the NLS_LANG is set
- to. In 9iR2, this limitation is removed. Data are returned in the
- same charset encoding as the client character set.
- BUG-1018797
- Extra characters may be appended to the end of a CLOB value
- mistakenly under the following conditions:
- - setCharacterStream() is used to insert a CLOB value, and
- - The Oracle server uses multi-byte character set.
- Driver Versions
- ---------------
- These are the driver versions in the 9.2.0 release:
- - JDBC OCI Driver 9.2.0
- Client-side JDBC driver for use on a machine where OCI 9.2.0 is
- installed.
- - JDBC Thin Driver 9.2.0
- 100% Java client-side JDBC driver for use in Java applets and
- applications.
- - JDBC Thin Server-side Driver 9.2.0
- JDBC driver for use by Java Stored Procedures or by Java CORBA
- objects running in Oracle 9.0.1. This driver is typically used
- in a middle tier server.
- - JDBC Server-side Internal Driver 9.2.0
- Server-side JDBC driver for use by Java Stored procedures. This
- This driver used to be called the "JDBC Kprb Driver".
- For complete documentation, please refer to "JDBC Developer's Guide
- and Reference".
- Contents Of This Release
- ------------------------
- The [ORACLE_HOME]/jdbc/lib directory contains:
- - classes111.zip & classes111.jar
- Classes for use with JDK 1.1.x. It contains the JDBC driver
- classes except classes necessary for NLS support in Object and
- Collection types.
- - nls_charset11.zip & nls_charset11.jar
- NLS classes for use with JDK 1.1.x. It contains classes necessary
- for NLS support in Object and Collection types.
- - classes111_g.zip & classes111_g.jar
- Same as classes111.zip, except that classes were compiled with
- "javac -g" and contain OracleLog traceing code.
- - classes12.zip & classes12.jar
- Classes for use with JDK 1.2.x. It contains the JDBC driver
- classes except classes necessary for NLS support in Object and
- Collection types.
- - nls_charset12.zip & nls_charset12.jar
- NLS classes for use with JDK 1.2.x. It contains classes necessary
- for NLS support in Object and Collection types.
- - classes12_g.zip & classes12_g.jar
- Same as classes12.zip, except that classes were compiled with
- "javac -g" and contain OracleLog tracing code.
- - classes12dms.jar
- Same as classes12.jar except contains additional code to support
- Oracle Dynamic Monitoring Service.
- - classes12dms_g.jar
- Same as classes12dms.jar except that classes were compiled with
- "javac -g" and contain OracleLog traceing code.
- - ojdbc14.jar
- Classes for use with JDK 1.4. It contains the JDBC driver
- classes except classes necessary for NLS support in Object and
- Collection types. Use nls_charset12.jar if needed.
- - ojdbc14_g.jar
- Same as ojdbc14.jar except that classes were compiled with
- "javac -g" and contain OracleLog tracing code.
- In general, <file>.zip and <file>.jar are identical except for the
- format of the archive. Both the .zip and .jar formats are provided
- for JDK 1.1 and JDK 1.2. Only .jar files will be provided for JDK
- 1.4 and beyond. So far, there is no need for JDK 1.3 classes files;
- use classes12.jar with JDK 1.3.
- Note that most of the classes pertaining to specific character sets
- support in Oracle Object and Collection types are separated from the
- basic zip/jar files. These NLS classes are packaged into the
- extension zip/jar files. This allows the user to include the NLS
- classes only if necessary. Please refer to the "NLS Extension Zip
- Files (for client-side only)" section for further details. Also
- note that the nls_charset files are much smaller than in prior
- releases. These .zip/.jar files now contain a more compact
- representation of the conversion information rather than actual
- .class files.
- [ORACLE_HOME]/lib directory contains libocijdbc9.so, libocijdbc9_g.so
- libheteroxa9.so and libheteroxa9_g.so (on Solaris), which are the
- shared libraries used by the JDBC OCI driver.
- [ORACLE_HOME]/jdbc/doc/javadoc.tar contains the JDBC Javadoc. This
- release contains a beta release of the Javadoc files for the public
- API of the public classes of Oracle JDBC.
- [ORACLE_HOME]/jdbc/demo/demo.tar contains sample JDBC programs.
- All of the sample programs have been rewritten to use JDK 1.2 and the
- new Oracle standard sample schemas. They no longer use the old standby
- scott/tiger schema. These new sample schemas are much more feature
- rich and so make it easier to demonstrate Oracle features. All Oracle
- sample code and training will be using these new schemas very
- soon. Most already does.
- NLS and NLS Extension Zip/Jar Files (for client-side only)
- ----------------------------------------------------------
- The JDBC Server-side Internal Driver provides complete NLS support.
- It does not require any NLS extension zip/jar files, nls_charset*.*.
- Discussions in this section do not apply to the JDBC Server-side
- Internal Driver. You can skip this section if you only use the
- Server-side Internal Driver.
- The basic zip/jar files (classes111.zip, classes111.jar,
- classes12.zip and classes12.jar, ojdbc14.jar) contain all the
- necessary classes to provide complete NLS support for:
- - Oracle Character sets for CHAR/VARCHAR/LONGVARCHAR/CLOB type data
- that is not retrieved or inserted as a data member of an Oracle 8
- Object or Collection type.
- - NLS support for CHAR/VARCHAR data members of Objects and
- Collections for a few commonly used character sets. These
- character sets are: US7ASCII, WE8DEC, WE8ISO8859P1 and UTF8.
- Users must include the appropriate extension zip in their CLASSPATH
- if utilization of other character sets in CHAR/VARCHAR data members
- of Objects/Collections is desired. It is important to note that
- extension zip files are large in size due to the requirement of
- supporting a large number of character sets. Users may choose to
- include only the necessary classes from the extension zip/jar file.
- To do so, users can first un-pack the extension zip/jar file, and
- then put only the necessary files in the CLASSPATH. The character
- set extension files are named in the following format:
- CharacterConverter<OracleCharacterSetId>.glb
- where <OracleCharacterSetId> is the hexadecimal representation of the
- Oracle character set id of the corresponding character set.
- In addition, users can also include internationalized Jdbc error
- message files selectively. The message files are included in
- classes*.* with the name oracle/jdbc/dbaccess/Messages_*.properties.
- -----------------------------------------------------------------------
- Installation

- Some Useful Hints In Using the JDBC Drivers
- -------------------------------------------
- Please refer to "JDBC Developer's Guide and Reference" for details
- regarding usage of Oracle's JDBC Drivers. This section only offers
- useful hints. These hints are not meant to be exhaustive.
- These are a few simple things that you should do in your JDBC program:
- 1. Import the necessary JDBC classes in your programs that use JDBC.
- For example:
- import java.sql.*;
- import java.math.*;
- 2. Register the Oracle driver before before calling other JDBC APIs.
- (This is not needed if you are using the JDBC Server-side Internal
- Driver because registration is done automatically in the server.)
- To register the Oracle driver, make sure the following statement
- is executed at least once in your Java session:
- DriverManager.registerDriver(
- new oracle.jdbc.OracleDriver());
- 3. Open a connection to the database with the getConnection call.
- Different connection URLs should be used for different JDBC
- drivers. The following examples demonstrate the different URLs.
- For the JDBC OCI Driver:
- Connection conn = DriverManager.getConnection(
- "jdbc:oracle:oci:@<database>",
- "my_user", "my_password");
- where <database> is either an entry in tnsnames.ora or a SQL*net
- name-value pair.
- For the JDBC Thin Driver, or Server-side Thin Driver:
- Connection conn = DriverManager.getConnection(
- "jdbc:oracle:thin:@<database>",
- "my_user", "my_password");
- where <database> is either a string of the form
- <host>:<port>:<sid>, a SQL*net name-value pair, or a service
- name.
- For the JDBC Server-side Internal Driver:
- Connection conn = DriverManager.getConnection(
- "jdbc:oracle:kprb:");
- Note that the trailing ':' character is necessary. When you use
- the Server-side Internal Driver, you always connect to the
- database you are executing in. You can also do this:
- Connection conn
- = new oracle.jdbc.OracleDriver().defaultConnection();
- New Package oracle.jdbc
- -----------------------
- Beginning in Oracle 9i, the Oracle extensions to JDBC are captured in
- the package oracle.jdbc. This package contains classes and interfaces
- that specify the Oracle extensions in a manner similar to the way the
- classes and interfaces in java.sql specify the public JDBC API.
- Your code should use the package oracle.jdbc instead of the package
- oracle.jdbc.driver used in earlier versions of Oracle. Use of the
- package oracle.jdbc.driver is now deprecated, but will be supported
- for backwards compatibility.
- All that is required to covert your code is to replace
- "oracle.jdbc.driver" with "oracle.jdbc" in the source and
- recompile. This cannot be done piecewise. You must convert all classes
- and interfaces that are referenced by an application. Conversion is
- not required, but is highly recommended. Future releases of Oracle will
- have features that are incompatible with use of the package
- oracle.jdbc.driver.
- The purpose of this change in to enable the Oracle JDBC drivers to
- have multiple implementations. In all releases up to and including
- Oracle 9i, all of the Oracle JDBC drivers have used the same top level
- implementation classes, the classes in the package
- oracle.jdbc.driver. By converting your code to use oracle.jdbc, you
- will be able to take advantage of future enhancements that use
- different implementation classes. There are no such enhancements in
- Oracle 9i, but there are plans for such enhancements in the future.
- Additionally, these interfaces permit the use of some code patterns
- that are difficult to use when your code uses the package
- oracle.jdbc.driver. For example, you can more easily develop wrapper
- classes for the Oracle JDBC classes. If you wished to wrap the
- OracleStatement class in order to log all SQL statements, you could
- easily do so by creating a class that wraps OracleStatment. That class
- would implement the interface oracle.jdbc.OracleStatement and hold an
- oracle.jdbc.OracleStatement as an instance variable. This wrapping
- pattern is much more difficult when your code uses the package
- oracle.jdbc.driver as you cannot extend the class
- oracle.jdbc.driver.OracleStatement. In implementing a Connection
- wrapper class, you should either inherit from the class
- oracle.jdbc.OracleConnectionWrapper, or base your class on that class.
- The source for oracle.jdbc.OracleConnectionWrapper is included in the
- demos directory.
- Once again, your code should use the new package oracle.jdbc instead
- of the package oracle.jdbc.driver. Conversion is not required as
- oracle.jdbc.driver will continue to be supported for backwards
- compatibility. Conversion is highly recommended as there will in later
- releases be features that are not supported if your code uses
- oracle.jdbc.driver.
- Java Stored Procedures
- ----------------------
- Please note that examples for callins and instance methods using Oracle
- 8 Object Types are provided in:
- [ORACLE_HOME]/javavm/demo/demo.zip
- Once unzipped, the directory containing the examples is:
- [ORACLE_HOME]/javavm/demo/examples/jsp
- Known Problems/Limitations In This Release
- ------------------------------------------
- The following is a list of known problems/limitations:
- * There is a limitation regarding the use of stream input for LOB
- types. Stream input for LOB types can only be used for 8.1.7 or
- later JDBC OCI driver connecting to an 8.1.7 or later Oracle
- server. The use of stream input for LOB types in all other
- configurations may result in data corruption. PreparedStatement
- stream input APIs include: setBinaryStream(), setAsciiStream(),
- setUnicodeStream(), setCharacterStream() and setObject().
- * Programs can fail to open 16 or more connections using our
- client-side drivers at any one time. This is not a limitation
- caused by the JDBC drivers. It is most likely that the limit of
- per-process file descriptors is exceeded. The solution is to
- increase the limit.
- * The Server-side Internal Driver has the following limitation:
- - Data access for LONG and LONG RAW types is limited to 32K of
- data.
- - Inserts of Object Types (Oracle Objects, Collections and
- References) will not work when the database compatibility mode
- is set to 8.0. This limitation does not apply when the
- compatibility mode is set to 8.1.
- - In a chain of SQLExceptions, only the first one in the chain
- will have a getSQLState value.
- - Batch updates with Oracle 8 Object, REF and Collection data
- types are not supported.
- * The JDBC OCI driver on an SSL connection hangs when the Java
- Virtual Machine is running in green threads mode. A work-around
- is to run the Java Virtual Machine in native threads mode.
- * Date-time format, currency symbol and decimal symbols are always
- presented in American convention.
- * When using OracleStatement.defineColumnType(), it is not necessary
- to define the column type to be the same as the column type
- declared in the database. If the types are different, the
- retrieved values are converted to the type specified in
- defineColumnType.
- Note: Most reasonable conversions work, but not all. If you find
- a conversion that you think is reasonable, but that does not work,
- please submit a TAR to Oracle Support.
- * The utility dbms_java.set_output or dbms_java.set_stream that is
- used for redirecting the System.out.println() in JSPs to stdout
- SHOULD NOT be used when JDBC tracing is turned on. This is
- because the current implementation of dbms_java.set_output and
- set_stream uses JDBC to write the output to stdout. The result
- would be an infinite loop.
- * The JDBC OCI and Thin drivers do not read CHAR data via binary
- streams correctly. In other word, using getBinaryStream() to
- retrieve CHAR data may yield incorrect results. A work-around is
- to use either getCHAR() or getAsciiStream() instead. The other
- alternative is to use getUnicodeStream() although the method is
- deprecated.
- BUG-899078 (since 8.1.6)
- The JDBC Server-side Internal driver has extra space padding with
- PL/SQL CHAR OUT (2 to 3 space depending on character set).
- Problem occurs in most of the multibyte database character set
- except UTF8.
- * There is a limitation for Triggers implemented in Java and Object
- Types. It only affects the IN argument types of triggers
- implemented using Java on the client-side. The restriction does
- not apply to JDBC programs running inside the server. Triggers
- implemented as Java methods cannot have IN arguments of Oracle 8
- Object or Collection type. This means the Java methods used to
- implement triggers cannot have arguments of the following types:
- - java.sql.Struct
- - java.sql.Array
- - oracle.sql.STRUCT
- - oracle.sql.ARRAY
- - oracle.jdbc2.Struct
- - oracle.jdbc2.Array
- - any class implementing oracle.jdbc2.SQLData or
- oracle.sql.CustomDatum
- * The scrollable result set implementation has the following
- limitation:
- - setFetchDirection() on ScrollableResultSet does not do anything.
- - refreshRow() on ScrollableResultSet does not support all
- combinations of sensitivity and concurrency. The following
- table depicts the supported combinations.
- Support Type Concurrency
- -------------------------------------------------------
- no TYPE_FORWARD_ONLY CONCUR_READ_ONLY
- no TYPE_FORWARD_ONLY CONCUR_UPDATABLE
- no TYPE_SCROLL_INSENSITIVE CONCUR_READ_ONLY
- yes TYPE_SCROLL_INSENSITIVE CONCUR_UPDATABLE
- yes TYPE_SCROLL_SENSITIVE CONCUR_READ_ONLY
- yes TYPE_SCROLL_SENSITIVE CONCUR_UPDATABLE
- BUG-1516862 (since 9.0.0)
- Passing an OPAQUE type as an argument to a Java Stored Procedure
- does not work.
- BUG-1542130 (since 9.0.0)
- The use of OciConnectionPool may cause a hang in a multi-threaded
- environment.
- BUG-1640110 (since 9.0.0)
- The JDBC OCI driver may hang when executing a query with invalid
- double quotes in the query string. This problem only occurs when
- the NLS_LANG environment variable is set.
- * Access to the new Datetime datatypes is only supported in the
- Jdbc Thin driver with JDK 1.2, 1.3 and 1.4. These Datetime data
- types inlcude: TIMESTAMP, TIMESTAMPTZ and TIMESTAMPLTZ. In
- addition, String APIs like PreparedStatement.setString() and
- Resultset.getString() do not work for these data types. Users
- must use setTIMESTAMP*() and getTIMESTAMP*().
- BUG-2171766 (since 9.2.0)
- When writing JDBC code that contains SQL method invocations,
- the syntax " ?.method(args,...) " results in the SQL error
- message: ORA-01036: illegal variable name/number. This message
- is somewhat misleading. What is required is that the ? must be
- followed by a " " (space) to avoid this issue.
- BUG-2165794 (since 9.2.0)
- DBC XA applications needing to use TMSUSPEND & TMRESUME features
- need to use the TMNOMIGRATE FLAG. If this flag is not used, the
- application may @receive Error ORA 1002: fetch out of sequence.
- BUG-2158394 (since 9.2.0)
- ORA-6505 when setting null to char column via stored procedure
- using setNull() method with java.sql.Types.CHAR. Using
- java.sql.Types.VARCHAR, is ok. Only occurs with Thin driver and
- JA16SJIS or JA16EUC character sets.
- BUG-2148328 (since 9.2.0)
- On Linux, SJIS data in table names are returned as replacement
- characters with JDK1.2 and JDK1.3 with both the Thin and OCI
- drivers. This is due to a bug in the JDKs. The workaround is to
- use JDK 1.1.8, which does not have this bug.
- BUG-2144602 (since 8.1.7)
- When running Windows2000 with the locale set to Chinese (Taiwan)
- and the character set set to ZHT16DBT, all Chinese characters
- are displayed as "?".
- BUG-2130384 (since 9.0.1)
- Does not raise ORA-22814 as it should when inserting too large
- of an element value into a VARRAY using setARRAY.
