When I run a PART LEVEL REORG (PART 1 in this case) of a PBG tablespace and the current data doesn't fit into its original partition DB2 adds a new partition at the end and uses it for the "overflow" data, although all the already existing partiti...
DSNZPARM to disable MODIFY option DELETEDS - compliance issue
It should be possible to disable the option for deleting physical datasets along with modifying recovery information for a tablespace, as in MODIFY RECOVERY TABLESPACE XXXXXX.XXXXXXXX
DSNUM ALL DELETE AGE(32) DELETEDS There is increasingly more ...
Allow for Multiple Columns on LOAD INTO TABLE WHEN Criteria
We recently converted from BMC to IBM Db2 utilities. It would be very useful if multiple column names could be specified on the WHEN criteria for the Db2 LOAD utility. This would also make the functionality similar to the WHEN criteria of REORG WI...
Automatically Perform a Display with Claimers when Utilities Cannot Perform a Drain on an Object
We recently migrated from BMC Utilities for Db2 to IBM Utilities. One feature that is sorely missed is that when the BMC Utilities would fail to drain because other processes had a claim on the object, BMC Utilities would perform a display with cl...
Idea For Limited Partition Locking for RI Related Objects
Lock just the partitions of related objects using a cascaded key structure when utilities are used to write to the database. Allows Db2 RI use to coexist with utility operation when it is impractical to lock all partitions of parents and children.
Record Conditional Image Copies That Are Bypassed In SYSIBM.SYSCOPY
We have a requirement to take daily image copies and to prove the copies were taken. When Db2 bypasses conditional copies from CHANGELIMIT (because NO CHANGE LIMIT MET) or from FULL NO (because TS CONTAINED NO CHANGED PAGES), Db2 does not record i...
Rearchitect the colgroup processing to be more granular using multiple sorts as opposed to a single sort or more intelligently avoid the colgroup sort altogether (when possible)
Looking at the job output you sent in, we can see that there are 18 colgroups specified.
Based on the current design, we have a single sort for colgroup(s).
There are 184310123 rows unloaded
The no. of the rows passed to the single
Record A Shrlevel Change Image Copy As Shrlevel Reference When Possible
Shrlevel change image copies that are older than the available Db2 logs can not reliable be used for recovery because there may have been inflight URs at the time of the copy that got backed out after the copy finished. To recover to current, Db2 ...
In a 24 hour online Db2 environment it can be difficult to complete an online REORG because the VSAM switch phase may fail, due to the activity on the tablespace being too high. The idea is to use the system monitors or a log analyzer tool to look...
REORG needs to be enhanced to separate processing for partitions having dictionaries and no dictionaries
Using LISTDEF there are 4 partitions selected to be reorged. Row length 2284 bytes KEEPDICTIONARY used PART 5 - CARDF 50M, dictionary PART 6 - CARDF 60M, dictionary PART 11 - CARDF 110M, dictionary PART 80 - CARDF 150,000, no dictionary Since PART...
