UNINTENDED AUTOMATIC TAKEOVER DURING CLUSTER SETUP USING DB2HAICU | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
To create an automated cluster controlled HADR environment, customers should provide correct localHost and remoteHost parameters for primary and standby XML files. However, some customers may use the same XML file for both systems. In that XML file, if localHost and remoteHost parameters point to primary and standby hostnames respectively, db2haicu will successfully complete the cluster setup. If we inverse the host names in that XML file, DB2 will think that the primary is supposed to be the standby and vice-versa which triggers an automatic takeover on the standby and swaps the database roles. | |
