If you experience any of the following problems, it might be time to perform a restore procedure.
If you are unsure that this procedure is correct, before proceeding, contact IBM® Rational® Software Support.
If you restore from an archive, the database server is restored to the state when the last archive level was performed. For example, if you restore from an archive completed the previous night, your database server is restored to the state when the archive took place. Also, all changes made after the previous night archive are lost unless your system administrator performed a logical log backup. See Managing logical log files.
Before you can restore a database server, ensure that the system configuration, the relevant database server parameter file, and, most importantly, the archive tapes are correct.
