INFORMIXOPCACHE (IDS)

The INFORMIXOPCACHE environment variable can specify the size of the memory cache for the staging-area blobspace of the client application.

>>-setenv--INFORMIXOPCACHE--kilobytes--------------------------><
 

kilobytes

specifies the value you set for the optical memory cache.

Set the INFORMIXOPCACHE environment variable by specifying the size of the memory cache in kilobytes. The specified size must be equal to or smaller than the size of the system-wide configuration parameter, OPCACHEMAX.

If you do not set INFORMIXOPCACHE, the default cache size is 128 kilobytes or the size specified in the configuration parameter OPCACHEMAX. The default for OPCACHEMAX is 128 kilobytes. If you set INFORMIXOPCACHE to a value of 0, Optical Subsystem does not use the cache.
