20.19.2 Actions to be taken

The actions to be taken are described below.

Procedure
To recover from an RDAREA shutdown:
  1. Back up the troubleshooting information under $PDDIR/spool.
  2. Back up the contents of the entire syslogfile before the error occurrence.
  3. Use the pdclose command to shut down RDAREAs that are in error shutdown status and their related RDAREAs (related table and index RDAREAs).
  4. Use the pdfbkup command to back up the files comprising the RDAREAs that are in error shutdown status and their related RDAREAs.
  5. After the above operations have been performed, restore the RDAREAs.
    There are two methods for restoring RDAREAs, as explained below.
Organization of this subsection
(1) Restoration method 1
(2) Restoration method 2

(1) Restoration method 1

If a backup for the system is available, restore the entire system during backup acquisition.

(2) Restoration method 2

Use the database structure modification utility (pdmod command) to reinitialize the RDAREAs that went into error shutdown status. This method deletes all data in the reinitialized RDAREAs. Restore the data from unload data files, input data files, and so on

The RDAREAs related to the reinitialized RDAREAs must also be restored logically.

Note that if HiRDB has not been restarted, the same error might have occurred in other RDAREAs.
