ON AIX 7.1 when env. variable is set like: export EXTSHM=ON and DB2ENVLIST includes EXTSHM, Following error is returned when running db2start in db2diag.log: 2016-10-22-01.25.24.368535+060 I1472833A622 LEVEL: Error (OS) PID : 8323260 TID : 1 PROC : db2star2 INSTANCE: db2pmba5 NODE : 000 HOSTNAME: pbhastplpw009 EDUID : 1 FUNCTION: DB2 UDB, SQO Memory Management, sqloMemSetPageSize, probe:100 MESSAGE : ZRC=0x820F0002=-2112946174=SQLO_INV_MEM "Invalid memory addr" DIA8561C A invalid memory block was encountered.

DATA #2 : Logical page size, PD_TYPE_MEM_PAGE_SIZE, 8 bytes 65536 This error is more cosmetic and should be replaced by a warning. Note that EXTSHM is only useful for 32 bit applications and should be unset in other cases. It is not a DB2 recommended setting, it being better to simply use loopback TCP/IP connections for 32 bit applications. | |
