We will focus on the “hadr_physical_seeding_progress” event today. I also configured the following extended event session to monitor seeding activity on the primary and secondary replicas. Bytes Received/sec on Secondary replicas.I configured the following performance monitor counters. Nothing else is active on the network or the replicas during the time of testing. This availability group has been configured with a separate 10Gbps network dedicated to endpoint traffic. Even if you decide to not use automatic seeding I recommend testing this feature as automatic seeding can be a great way to stress your endpoint network to validate its throughput. There is also a bonus feature of automatic seeding for DBA’s and Information Technology professionals. It will also join the database on the replicas for you.

This eliminates the need to manually take full and log backups from the primary replica to all the secondary replicas. Automatic seeding utilizes a VDI Backup to take a copy only backup and send it over the endpoint network to seed the replicas and then join the databases with the replicas.

It’s how the initial data synchronization occurs for Geo-Replication of Azure SQL Databases. Here is how I added a 60TB (Yes, TB not GB) database to an availability group that utilized multiple data centers.Īutomatic seeding is a feature that has been in Azure SQL Databases for a while. Personally, I have been a big fan of log shipping for the initial data synchronization of VLDB’s especially when you need more than two replicas. In the past, data initialization has been done with mirroring, log shipping, backup, and restores. When you add a database to an availability group, the replicas must synchronize the data between the availability groups to join the database on the replicas. They definitely come highly recommended.The initial data synchronization easy button. It has been an absolute pleasure working with professionals like Sia and his team and they have absolutely surpassed all expectations. We are on the road to recovery now and one of the best things we could have done is to outsource our database environment to DBA Services.

After the change, an integration that timed out after 15 minutes completed in less than 10 seconds!Our environment is extremely complex and years of bad practices have resulted in many issues which we were unable to explain. It didn't take them long to pinpoint that a specific index in our database was not performing optimally and recommended to recreate it. After 6 months of no success (and very unhappy users) we involved DBA Services in trying to get to the bottom of the issue. investigated, involved our support partner and later even the vendor. … rebuild the indexes to make sure it’s all performing nicely USE MSDBĮXEC sp_MSforeachtable '?'

MSDB should be back under control, and your scheduled history clean-up task capable of completing successfully again!Ī while ago we had serious database locking issues while trying to integrate transactions into our ERP system.

Then we shrink it down - SHRINK THE MSDB LOG FILE ORDER BY sum(a.total_pages) DESC, object_name(i.object_id)Ĭhances are it will be the sysmaintplan_logdetail table that’s blown out, so to resolve this ALTER TABLE.

How to check and fix a large MSDB database – first check what’s using the space SELECT object_name(i.object_id) as objectName, Generally running a clean up history task will resolve this, however in the event that this is failing also, you can try the following scripts to fix the issue. For the most part this should generally remain well under 1GB in size (normally only a few hundred MB)… but there are certain conditions where the history clean up task can get a bit overwhelmed and start failing, and leave you with an MSDB database that’s starting to grow a bit out of control. The MSDB database houses your maintenance plan information and job histories (amongst a few other things).
