Capacity Planning for Record Data Entries z/OS MVS Programming: Sysplex Services Guide SA23-1400-00 |
|
On each IXLLOCK OBTAIN and ALTER request that specifies record data is to be written, XES returns information about the number of record data entries currently in use. Either the ENTRYCOUNT output field in the IXLLOCK parameter list or the CMPLRTENTRYCOUNT field in the IXLYCMPL parameter list, if processing was asynchronous, contains this value. Use the value returned in ENTRYCOUNT or CMPLRTENTRYCOUNT to monitor how much storage remains in the structure for record data entries. The approximate maximum number of record data entries that the structure supports is returned in the answer area by IXLCONN (field CONALOCKMAXRECORDELEMENTS). You can also determine this value by using the XES Accounting and Measurement service, IXLMG, to request structure information. By comparing the value of ENTRYCOUNT with the value of the maximum supported number of record data entries, you can anticipate a “structure full” situation and take appropriate actions to avoid the occurrence of such a condition. |
