Restart requirements

Before the DBH can carry out a restart, the following requirements must be met:

• The DBH must be running with transaction management (default mode).

• The TA-LOG files (transaction log files) must be available.
  Its default name is:

  • SESAMcn.TA-LOG1 and SESAMcn.TA-LOG2 for the independent DBH and

  • SESLKcn.TA-LOG1 and SESLKcn.TA-LOG2 for the linked-in DBH.

• The WA-LOG file (restart log file) must be available.
  Its default name is:

  • SESAMcn.WA-LOG for the independent DBH and

  • SESLKcn.WA-LOG for the linked-in DBH.

The TA-LOG files and WA-LOG file include in their names the configuration name (c) and the DBH name (n) defined by means of the DBH option DBH-IDENTIFICATION when the aborted session was started.

If the TA-LOG files and WA-LOG file are not available, the DBH cannot carry out the restart. The database administrator then has to use the appropriate utility statements to repair logically inconsistent databases (see the “SQL Reference Manual Part 2: Utilities”).
