DADS Plus for CICS has a feature that allows the user to modify the DFHRPL library concatenation without bringing down CICS. It is possible to dynamically add or remove libraries or change the order in which libraries are searched. In order to use the DFHRPL LIBRARIES MANAGEMENT (option 2) located on the DADS Plus for CICS Primary menu, the DADS Plus for CICS SVC must be installed. The SVC number is stored in the DADS Plus for CICS file control and is listed on the Global Allocation Options Display menu. If the parameter is set to SVC=000, the DFHRPL libraries management feature will be disabled.
There are two ways to access the Global Allocation Options Display menu after signing on to CICS. From a clear screen, enter transaction DADS and press ENTER and the DADS Plus PRIMARY MENU appears. Next, select option 1 - DYNAMIC ALLOCATION FACILITY and press ENTER and the DYNAMIC ALLOCATION FACILITY MENU appears. Next, select 6 OPTIONS - DISPLAY/MODIFY GLOBAL ALLOCATION OPTION and press ENTER and the GLOBAL ALLOCATION OPTIONS DISPLAY appears. The GLOBAL ALLOCATION OPTIONS DISPLAY menu can be displayed by entering the DADC transaction from a clear screen in CICS and pressing ENTER.
The DADC transaction is a shortcut that gives the user direct access to global allocation options menu. In some environments, the DADC transaction may not be available due to security requirements.
The SVC= parameter CAN ONLY be updated using the batch utility program DADBCNTL and if CICS is active, the DADS Plus for CICS control (DADS01) MUST be closed.
The following JCL updates the control file and sets SVC=000.
//DADBCNTL EXEC PGM=DADBCNTL,REGION=700K
//STEPLIB DD DSN=DADSPL40.LOADLIB,DISP=SHR
//DADS01 DD DSN=DADSPL40.DADS01.CONTROL,DISP=SHR
//SYSPRINT DD SYSOUT=A,DCB=(LRECL=133,RECFM=FBA,BLKSIZE=133)
//SYSIN DD *
UPDATE
SVC=000
/*
If the SVC is not installed (SVC=000), the user will receive the message DP845 when they attempt to use this feature.
DP845: CA-DADS/PLUS DFHRPL PROCESSING NOT POSSIBLE - SVC NOT DEFINED.
