When the Optical Subsystem needs more memory

Usage

OPCACHEMAX specifies the size of the memory cache for the Optical Subsystem. The database server stores pieces of TEXT or BYTE data in the memory cache before it delivers them to the subsystem. Use this parameter only if you use the Optical Subsystem.

The INFORMIXOPCACHE environment variable lets the client restrict the size of the optical cache that it uses.
