For these specifications:
Publisher: (prod OLTP DB server) SQL Server 2005, database size : 220 GB also acts as the distributor
Subscriber (Prod reporting DB server): SQL Server 2005, DB gets replicated and is currently in sync.
Now, as per the yearly activity there would be a script run on OLTP publisher DB to delete more than 3516009 records.
Please suggest if this breaks transaction replication? Or is there a way I can prevent one because setting that up is tedious?
Also, something similar was done 2 years back and we only have the error as
The process could not execute 'sp_replcmds' on 'xxxxxx'." "Status: 2, code: 0, text: 'Timeout expired'" "A time out occurred while waiting for memory resources to execute the query." "Agent 'xxx' is retrying after an error. 0 retries attempted. See agent job history in the Jobs folder for more details." "The step was cancelled (stopped) as the result of a stop job request""
And the fix that was done at that time was to increase the query time-out for log reader agent and was set from default of 1800 to a max 65333 secs.
Since the DB has grown over last 2 years we are wondering, if above fix will still be good or should we take any measures?
Also, in case replication breaks, what can be the fastest way to bring it back because setting the whole thing up (especially SQL Server 2005) will bring a big outage on reporting server?
