15.4.2 Recovering the server directory

If a problem occurs on a disk so that it is necessary to recover the server directory, recover the server directory by re-installing the HADB server.

Note that the server directory can be restored to the status it was in before the problem occurred only if the following conditions are satisfied:

• A problem such as a disk error has not occurred in the HADB server's DB directory.

• All files stored under the server directory (in $ADBDIR/conf and $ADBDIR/sample) have been backed up.

• If users have created files under the server directory ($ADBDIR), those files have been backed up.

To recover the server directory:

1. Re-install the HADB server.

   Rebuild the server directory by re-installing the HADB server. For details about how to install the HADB server, see 8.2.2 Installation procedure.

2. Recover the definition files and sample application program from the backup.

   From the backup, restore all files that were stored in the server directory (in $ADBDIR/conf and $ADBDIR/sample).

3. Recover the files that were created by the user from the backup.

   If users have created files in the server directory ($ADBDIR), restore those files from the backup.

4. Restart the HADB server.

   Execute the adbstart command. The HADB server is restarted.
