We are running DB2 version 11 NFM on z/OS 2.3 and during start up after an IPL, our DBM1 started task took a dump with the following title: PH1D,ABND=0C3-00000003,U=SYSOPR ,M=N ,C=111.ASMC-DSNVDSRB,M=DSNVIALC, PSW=077C0001BDAE2C18,A=009E I will FTP tersed copies of the dump, SYSLOG and EREP reports for the time of the dump, and DB2 the started task joblogs. Please let me know if you need any additional information
Dump shows S0C3 abend in CASR230U because the pointer to the real copy of a DB2 module is zero in the expected ENF/DB2 control block. It looks like a timing issue where an intercept was driven before its "implantation" was complete.
Level 2 attached ST05153 to this case for download via SUPPORT.CA.COM . It can be located in the "File Attachments" tab. To implement: Deploy updated CAW0LOAD, refresh LLA if necessary and issue command: ENF REFRESH(CASR230)
