Automatic Recovery

As described in Starting the FairCom Server, each time the FairCom Server starts it checks the current active transaction logs and determines if any transactions must be undone or redone. If any recovery operation is required, the FairCom Server does it automatically. The Administrator need not do anything. The FairCom Server displays messages indicating the beginning and the end of the recovery. When automatic recovery completes, the FairCom Server is ready to use.

Performance Improvements in V12

Automatic Recovery could take a long time to complete if many files were referenced in the transaction logs. Backup recovery logic has been enhanced to greatly speed this process.

As an example, this performance enhancement reduced the time of ctrdmp restoring 1500 data and 1500 index files from 406 sec. to 63 sec.
