BMC PACLOG for DB2

Compress DB2 on z/OS logs for greater availability and cost savings

Large DB2 on z/OS archive logs require many tapes, making it difficult to access data for recovery. Mounting multiple tapes during a recovery is time-consuming and costly. Many logs contain records that are not needed for recovery, such as index-related log records and log data for user-specified objects.

BMC solution

BMC PACLOG for DB2 provides substantial archive log media savings so that more archive log data can be stored on DASD, making the data more accessible for recovery. It eliminates multiple tape mounts, operator interaction and rewinding tape. PACLOG uses a patented filtering process and the Extended Compression Architecture (XCA) technology to achieve up to a 95% reduction in the size of DB2 archive logs. It also offers improved filtering rates to allow index recovery to effectively eliminate archive log records not needed for recovery. Logs processed by PACLOG can reduce network transmission times in support of disaster recovery.

Features and benefits

• Supports speedier recovery processing by improving the availability of log data on disk.
• Eliminates archive log records not needed for recovery, resulting in less downtime
• Evaluates logging choices and calculates the optimum size and number of active logs needed
• Provides easier management of DASD and tape storage using a flexible media storage capability and log management reports.
• Allows you to make up to four copies of the original archive logs. (two for local site use and two for recovery site use)

Key differentiators

• Reports on archive logs that are no longer usable by DB2 and logs that have been processed, saving valuable DASD and tape storage.
• An interactive modeling tool models your DB2 logging environment so you can evaluate alternative logging choices
