DWW282I
MAXIMUM POOL SIZE REACHED IN LSQA STORAGE
The available 31-bit high private system area in the CICS VR sever address space was at a critically low level such that using more storage could result in its failure. To prevent an out of storage condition and abnormal termination of CICS VR, functions that would result the remainder being below the limit (defined in the CICSVR_ZZVALUE_PARM - XXXTRAPS value) are not performed.
System action
The system continues processing. See additional CICS VR messages related to the impacted functions.
Operator response
Refer to additional CICS VR messages such as DWW267I, DWW259I , etc. to determine what preventative actions can be taken. Contact the System programmer.
System Programmer Response
Refer to additional CICS VR messages. If needed, Contact the IBM Support Center.
With the guidance of IBM service personnel, the limit value may be changed with the CICSVR_ZZVALUE_PARM parameter of the SETSMS command . The changed value will be active at the next start of the CICSVR server. See the CICS VSAM Recovery for z/OS documentation for the syntax of the command and the default value.
By subtracting the values of VSMWCONTIG and VBLSTORAGE in DWW014I message (these values are printed during CICSVR activation) we can get to know the amount of reserved storage.
Sample DWW014I message during CICSVR activation:
- DWW1IRCM VSMWTotal: 740F6000
- DWW1IRCM VSMWContig: 740EB000
- DWW1IRCM VBLStorage: 727EB000
Amount of Reserved Storage = VSMWContig – VBLStorage. In this example, Reserved storage = 740EB000 - 727EB000 = 19MB
The reserved storage limit value may be changed with the SETSMS command. The changed value will be active at the next start of the CICSVR server. The format of SETSMS command is:
SETSMS CICSVR_ZZVALUE_PARM(XXXTRAPS xx),
where xx (00-FF) is the storage in MB reserved for CICSVR control and non-critical data blocks.
