Is there a log reuse wait DESC for replication?
Log_reuse_wait_desc once led me down the rabbit-hole of resolving a database showing Replication as the wait type, when there’s no replication configured. That was *loads* of fun… I have the same problem.
Why does SQL Server not reuse log files?
This means, that a log record of a committed transaction is still required for crash recovery until the next checkpoint has been executed. In this situation the virtual log files containing these log records cannot be reused and SQL Server reports CHECKPOINT in the log_reuse_wait_desc column. This wait type is usually short lived.
Why is there a log reuse wait in checkpoint?
Today’s log reuse wait reason is: CHECKPOINT The SQL Server query engine never directly interacts with the data files on disk. Instead it requests the data pages it needs to process a query from the buffer pool manager.
What to do when log reuse does not work?
Tried the usual – log backup –> shrink changed to simple and back does not work. Bala – for personal consulting, click Consulting at the top of the screen. Solved – Adding the database back to the AG group (No need to add all the replica nodes) and then removing it again freed whatever was stuck and made the server thinking it is replicating.
How to resolve replication wait type in SQL Server?
To resolve the REPLICATION wait type, make sure the network connection to the distributor is working and the distributor can handle the current work load. If the publisher and the distributor are on the same SQL Server instance or on the same physical machine, consider moving the distributor to dedicated hardware.
Why are virtual log files not reused in replication?
Transactional replication uses a log reader agent to read and process all committed transactions in the publication database. Virtual log files containing log records that have not been processed yet cannot be reused. If the log reader agent falls behind, SQL Server will eventually run out of virtual log files.
Why is there no replication in sys.databases?
I checked the sys.databases log_reuse_wait_desc column and it shows “replication” as the reason the log won’t allow shinking. The problem is that there is no replication (publisher or subscriber) on the database or on the server.
