Environment Variable

Values and Description

USECACHEDEV

Y or N

The default setting is N

Enables the Genfile Cache in a Development Environment, that is when proiv.virtualMachine.vm.public.proRunType is DEV

USECACHERUN

Y or N

The default setting is N

Enables the cache when PRORUNTYPE is not set to DEV, e.g. BATCH, COMPONENT and RUN.

CACHEMAXBYTES

1 - 32MB

The default setting is 2

The maximum size of the cache in megabytes. This is an integer between 1 and 32. 2 MB is appropriate for most applications and 1 MB for Bus and Tasks.

CACHEFULLFLUSH

Y or N

The default setting is Y

Determines the behaviour when the cache is full. If set to Y, the cache is flushed when it full. This approach is adequate and removes old data such as the LOGON function which is run once.

Bus and Tasks and other single shot applications may benefit more from not flushing and keeping the old data. The best choice depends on the application. If not flushed, the cache remains until the Virtual Machine terminates.
