Having a backup of all the catalog and directory table spaces is critical to ensure recoverability to a previous version of DB2. This is just another attempt to ensure that nothing ad,inistration broken in any of the DB2 system objects. Like what you just read? These catalog and directory table spaces will have their links and hashes removed while being converted to universal table spaces during the Enabling New Function Mode ENFM process. To do this, select option 2 on the User Mode Entry panel.
More Articles From George Ng. One way to provide such information is to develop homegrown tools using facilities already available within the OS.
Power users most likely will want to develop and manage their own reports more to their preferences. Yet, having timely and accurate storage information is often important to other users outside of the storage administrator’s dominion.
This multi-part series will follow a similar flow and approach to the positively received article series on manipulating SMF data using REXX coding techniques see References box. The first of these three panels is shown in Figure 3. The first optional job step, Migration Step 2, runs the standalone DB2 utility DSN1CHKR, checking the five catalog table spaces that use links and one directory table space that uses hashes for broken links, broken hash chains, and orphans.
The ENFM conversion process can only be more successful knowing that the inputs to the conversion are clear of problems. Some installations restrict end users from gaining access to the storage administrator panels to prevent unauthorized users from performing storage administrator tasks.

But now, DB2 10 may have come up with the biggest incentive of all. Read The Current Issue: For some however, these tools can be somewhat esoteric to use. This will verify that all the catalog and directory table space pages are physically correct and that the catalog table spaces are clustered.
