IN MULTIPLE DATABASE PARTITIONS ENVIRONMENT, SINGLE SYSTEM VIEW (SSV) BACKUP MAY RUN INTO VIOLATING NUM_LOG_SPAN PROBLEM WITH AD |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
As a rule, DB2 backup commands are excluded from the limitation
imposed by the num_log_span configuration parameter.
However, while doing the Single System View (SSV) backup in
multiple database partitions environment, violating num_log_span
problem might be raised up with ADM1541W message as belowing
db2diag.log entries:

MESSAGE : ADM1541W Application "db2bp" with application handle
"1-30160" and
application id "*N1.Christine.120411094113" executing
under
authentication id "AlanDB2 " has been forced off of
the database for
violating database configuration parameter
NUM_LOG_SPAN (current
value "17"). The unit of work will be rolled back.
During SSV backups, log span immunity is set only for the
MPPRequestor agent (ie. the coordinator of all the backup
agents). However, the same immunity is not granted to the actual
backup agents spawned by the coordinator. In a non-SSV backup
there is no MPPRequestor and the backup agent itself is granted
log span immunity, thus the situation arises only in the SSV
case. |
