Shulou(Shulou.com)06/01 Report--

I encountered a problem when doing DB2 HADR takeover today.

SQL1387W A DB2 High Availability Disaster Recovery (HADR)

Takeover completed successfully. However, a HADR resource group remains locked

The virtual IP controlled by DB2 TSA really did not switch to old standby.

First use lssam to check the status of the resoure group of the corresponding database.

Then unlock it with the root user: rgreq-o unlock

After unlocking, you see the virtual IP

The IBM official document says that TSA wants to rebuild domain after the upgrade. I didn't rebuild it at that time, probably because of this reason.

On Primary and Standby, under each db2 instance, do db2haicu-delete to delete the old domain

And then rebuild.
