Problem description: | |
With an HADR pair set up (Machine A as HADR Primary, and Machine B as HADR Standby), the following introduces an error: 1) Machine A: connect to db <dbname> 2) Machine A: db2 set write suspend for db 3) Machine B: takeover hadr for db <dbname> On Machine B, the 'takeover hadr' command will hang. On Machine A, the database connection is lost, and the following error may be encountered: SQL1224N The database manager is not able to accept new requests, has terminated all requests in progress, or has terminated your particular request due to an error or a force interrupt. SQLSTATE=55032 Further attempts to connect to the db on Machine A will yield: SQL1776N The command cannot be issued on an HADR standby database. Reason code = "2". This problem can be avoided by unsetting 'write suspend' on Machine A, or by using the 'BY FORCE' option with the HADR takeover command. | |
