LOCKING TABLE EVENT LOCKING MONITOR SHOULD USE NULL VALUES WHEN DATA IS UNAVAILABLE | |

DB2 FOR LUW / DB2FORLUW / A10 - DB2 | |
Problem description: | |
If a locking event monitor is defined to be UNFORMATTED EVENT TABLE (rather than TABLE) and EVMON_FORMAT_UE_TO_TABLES is used to move the unformatted data into relational tables, NULL values are used for columns where data is not available. However a locking event monitor defined to be TABLE will use 0 values for numeric columns, empty strings for character columns and a value of "0000-00-00-00.00.00.000000" for timestamp columns. These timestamp column values can cause issues when exporting / importing the data from the event monitor table. This APAR modifies locking TABLE event monitor processing to use NULL values when data is not available (that is, so that it's data matches the data produced by EVMON_FORMAT_UE_TO_TABLES when run against a locking UNFORMATTED EVENT TABLE event monitor Affected columns in the lock_participants table are: - lock_current_mode - lock_mode_requested - lock_mode - lock_count - lock_hold_count - lock_rriid - lock_status - table_file_id - threshold_id - lock_wait_start_time - lock_wait_end_time - participant_no_holding_lk - object_requested - lock_name - lock_object_type - lock_object_type_id - lock_attributes - lock_release_flags - table_name - table_schema - tablespace_name - threshold_name - queued_agents - queue_start_time Affected columns in the lock_participant_activities table are: - stmt_first_use_time - stmt_last_use_tim | |
