RUWAPOOL
The RUWAPOOL parameter specifies the option for allocating a storage pool the first time a program invoked by Language Environment® runs in a task.
Defining RUWAPOOL
You can define the RUWAPOOL system initialization parameter in the following ways:
- On the PARM parameter of the EXEC PGM=DFHSIP statement
- In the SYSIN data set of the CICS® start up job stream
- Through the system console
- In the DFHSIT macro
Values for RUWAPOOL
- RUWAPOOL={NO|YES}
- NO| is the default value for RUWAPOOL. Valid values for the RUWAPOOL system initialization parameter are as follows:
- NO
- CICS disables the option and provides no RUWA storage pool. Every EXEC CICS LINK to a program that runs under Language Environment results in a GETMAIN for RUWA storage.
- YES
- CICS creates a pool of storage the first time a program
invoked by Language Environment runs in a
task. This provides an available storage pool that reduces the need to GETMAIN
and FREEMAIN run-unit work areas (RUWAs) for every EXEC CICS
LINK request. Note: This applies only to application programs running with the Language Environment runtime option ALL31(ON). RUWAPOOL=YES has no effect on application programs running with the Language Environment runtime option ALL31(OFF).
