Problem IT29768 | Status: Closed |
DB2 PURESCALE MEMBER MAY HIT FODC_PANIC DUE TO XI FAILURES IN RUSCENARIO. | |
product: | |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 | |
Problem description: | |
After updating the CF's to V11.1.4.4, members on V11.1.4.4 may begin to experience XI failures if there are any members remaining on the previous Db2 level. Eventually, these errors may cause the member to FODC. This is due to the primary CF on the V11.1.4.4 level being unable to invalidate pages on down level members on behalf of V11.1.4.4 members. This will often result in the V11.1.4.4 members reaching the communication timeout and causing a FODC 6 minutes after the initial XI failures. | |

**************************************************************** * USERS AFFECTED: * * ALL * **************************************************************** * PROBLEM DESCRIPTION: * * See Error Description * **************************************************************** * RECOMMENDATION: * * Upgrade to Db2 11.1 Mod 4 Fixpack 5 or higher * **************************************************************** | |
Local Fix: | |
This issue can be avoided by updating all members to a higher level before updating the CFs. If the cluster is already in a state with mixed level members, shutdown the lower level members and update them to V11.1.4.4 before bringing them back online. | |
