Setting Up an Oracle Database

The following notes apply to Oracle:

  • The Oracle clients have a configuration parameter that allows you to specify a rollback segment larger than the default rollback segment. You can use a rollback segment to execute the SQL statement SET TRANSACTION USE ROLLBACK SEGMENT at the start of every transaction.

  • The Oracle clients support the CLOB data type for holding DMSII ALPHA items that are too large for the VARCHAR2 data type. The parameters in PL/SQL stored procedures for these clients limit the CLOB data type to 32K (Oracle 11g). For backward compatibility, this feature is enabled via the use_clob parameter.

  • Starting in Oracle 11g Release 2, Oracle database passwords are case-sensitive.

The Oracle open_cursors Parameter

We recommend that you add the open_cursors parameter to the initSID.ora file. Depending on the setting of the aux_stmts parameter, you may need to increase the value of open_cursors to make it slightly higher than the value of aux_stmts.

If open_cursors is not set high enough, an error occurs, indicating that the maximum number specified was exceeded. Refer to your Oracle documentation for information on setting these values.
