- I did not spend much time for tuning crash-me or the limits file. In short,
- here's what I did:
- - Put engine into ANSI SQL mode by using the following odbc.ini:
- [ODBC Data Sources]
- test
- [test]
- ServerDB=test
- ServerNode=
- SQLMode=3
- - Grabbed the db_Oracle package and copied it to db_Adabas
- - Implemented a 'version' method.
- - Ran crash-me with the --restart option; it failed when guessing the
- query_size.
- - Reran crash-me 3 or 4 times until it succeeded. At some point it
- justified its name; I had to restart the Adabas server in the
- table name length test ...
- - Finally crash-me succeeded.
- That's it, folks. The benchmarks have been running on my P90 machine,
- 32 MB RAM, with Red Hat Linux 5.0 (Kernel 2.0.33, glibc-2.0.7-6).
- Mysql was version 3.21.30, Adabas was version 6.1.15.42 (the one from
- the promotion CD of 1997). I was using X11 and Emacs while benchmarking.
- An interesting note: The mysql server had 4 processes, the three usual
- ones and a process for serving me, each about 2 MB RAM, including a
- shared memory segment of about 900K. Adabas had 10 processes running from
- the start, each about 16-20 MB, including a shared segment of 1-5 MB. You
- guess which one I prefer ... :-)
