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 for the ideal 'sweet spot' to perform the switch. That is identify a time when activity is at a minimum for that tablespace. Once the sweet spot switch time is found then estimate how long it would take to build the shadow VSAM files.
Sweet spot time minus the time to build the shadow VSAM files tells you the time to start the REORG job.
This will give maximum possibility for the REORG switch phase to complete.
Will save wasted CPU time in running a REORG that ultimately fails.
