Error description
DSMAX reached after PH27493 / UI71764 is applied for a COPY SHRLEVEL REFERENCE job of a list of 4285 tablespaces or partitions with : DSNT500I <DBU2 DSNUGRAR RESOURCE UNAVAILABLE REASON 00C20113 TYPE 00000220 Additional symptoms: RC00E4010A 00E4010A MSGDSNT500I
Local fix
Use COPY SHRLEVEL CHANGE and OPTION(ITEMERROR,SKIP) to avoid having all the tablespaces in the list opened at once.
Problem summary
**************************************************************** * USERS AFFECTED: * * All Db2 12 for z/OS users with * * PH27493/UI71764 applied. * **************************************************************** * PROBLEM DESCRIPTION: * * COPY utility job ended with ABEND04E * * RC00E4010A due to table space or * * index open failure with RNA reason * * code RC00C20113, when the open * * dataset count exceeds the DSMAX. * **************************************************************** * RECOMMENDATION: * * Apply corrective PTF when available * **************************************************************** With PH27493/UI71764 applied, COPY utility job may end with ABEND04E RC00E4010A due to table space or index open failure with RNA reason code RC00C20113, when the open dataset count exceeds the DSMAX. The dataset close processing logic has been improved to proactively close datasets that were opened solely for utility access in PH27493. When approaching DSMAX or when DSMAX is reached, Db2 will prioritize the closure of utility-only datasets over those datasets that have been accessed by applications. However, the utility-access-only datasets are excluded from DSMAX processing mistakenly in the enhancement of PH27493. This causes the utility-access-only datasets to not be closed when DSMAX is being reached, and could therefore cause dataset open failures such as the ABEND04E RC00E4010A for the COPY utiility.
Problem conclusion
Db2 code has been modified to include and prioritize the closure of utility-only datasets properly when approaching DSMAX or when DSMAX is reached.
