- # Test of creating a simple table and inserting $record_count records in it,
- # $opt_loop_count rows in order, $opt_loop_count rows in reverse order and
- # $opt_loop_count rows in random order
- #
- # changes made for Oracle compatibility
- # - $limits{'func_odbc_mod'} is OK from crash-me, but it fails here so set we
- # set it to 0 in server-cfg
- # - the default server config runs out of rollback segments, so I added a couple
- # of disconnect/connects to reset
