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.
Slow performance was sometimes experienced when using the ctrdmp utility to restore a large number of files and transaction activity occurred during the dynamic dump. Recovery utility performance has been improved for these activities. This change has no impact on configuration or compatibility. Using the updated ctrdmp utility resolves the slow performance for a dynamic dump stream file that exhibited slow performance under these conditions.
