Case number caching can provide a performance benefit when applied to the BG,
WIS, RPC_POOL, and
SWBATCH processes. It should not be used with other processes. For more information see
Sequence Number Caching.
For example, suppose that a WIS process has 50 case numbers (1 to 50) cached, and a user uses the
SWUTIL CSTART command to start a case. The case will have case number 51 - the next available number obtained from the
cnum_sequence table.
However, if a user then starts a case through the WIS, that case will have case number 1 - the next available number in the cached sequence.
