Database options

The following database options have been added or have enhanced functionality:

  • ansi_substring database option   This option controls the behavior of the SUBSTRING function. By default, the behavior of the SUBSTRING function now corresponds to ANSI/ISO SQL/99 behavior.

  • default_dbspace option   This option allows you to specify the default dbspace where your tables are created. See default_dbspace option.

  • http_session_timeout option   The http_session_timeout option provides variable session timeout control. The option setting is in units of minutes. By default the public setting is 30 minutes. Minimum is 1 minute and maximum is 525600 minutes (365 days). See http_session_timeout option.
