The frequency of the tasks is determined by your operational requirements. The following are general recommendations only.
• Browse the Data Object Broker JES log for messages that warn of segment space problems, for example:To view the percentage of free pages in each segment, choose the ADMIN utility option B SEGMENT/DASD.
• Browse the Data Object Broker JES log for messages that warn of issues in resource definitions, for example:
• Browse all multiuser Execution Environment JES logs for any unusual error messages or rule failures. Follow-up on the issues, if any.
• Check for application updates, including those for new applications. Install the updates that are appropriate.
• If you have not set up continuous backup, perform offline segment backups, assuming that a window exists, and ensure that Batch Pointer Check (S6BBRPTR) shows that the backups are clean. If the time window is not sufficient for backups, run a DASD—not a backup—Batch Pointer Check against each offline segment. That task requires no backup but still confirms the physical consistency of the segments.
• If you are using peer processing or external database gateways, choose the ADMIN option 1 IN-DOUBT TRANSACTIONS to confirm that no in-doubt transactions are pending. In case of any, find out why TIBCO Object Service Broker has not automatically resolved them or resolve them manually.
• Verify that the test and certification systems are synchronized with the systems to which software updates are to be applied.
• Examine all multiuser Execution Environment JES logs for information on the amount of virtual storage space and create an ongoing profile of space availability. Review the message like the one below and record the available storage space:S6BST301I STORAGE AVAILABLE AT STARTUP IS nnnnK OF 24 BIT AND nnnnnnK OF 31 BIT
• Select option A of the ADMIN utility to review the logical GET to physical READ processing. Strive for a successful hit ratio of at least 95 percent. See this formula:If the hit ratio is substantially less than 95 percent, increase the resident page pool size (Data Object Broker parameter RESIDENTPAGES) to hold more page images in memory and avoid I/O to the segment page data sets.
You can manually create an ongoing processing profile of virtual storage space, DASD space, I/O, response times, and other metrics with such tools as ADMIN and HMON. However, a better approach is to activate the product-based SMF recording and automate the process of extracting, archiving, and analyzing the data.
