Problem IC70978 | Status: Closed |
RELEASING FCM RESOURCES MAY TAKE LONGER THAN EXPECTED | |
product: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problem description: | |
In DPF environments, the release of FCM buffers or channels may take longer than expected if a large number of FCM resources are allocated. One possible consequence of this is db2stop may time out due to it taking a relatively long time to free fast communication manager resources. FCM is shut down during the final phase of db2stop. When this phase takes longer than the time specified by START_STOP_TIME then the node is forcefully terminated. Another possible consequence is performance slowdowns that coincide with periods when FCM automatic tuning releases resources. | |

Local Fix: | |
If db2stop is timing out then increase the START_STOP_TIME value in the database manager configuration. | |
