Dear Sir, when we configure sql server 2016 for mirroring we find the error:
database cannot be opened. it is in the middle of a restore error no 927
Thank you so much sir for sharing this mirroring video nice explained no Waste of time
My pleasure
Really good video, very clear and helpful. Thanks a lot.
Very much helpful. Thank you.
Please keep them coming.
Hello
Despite usage of Witness Server, you did Manual Failover. Please explain if Automatic Failover wouldn't happen with your setup?
Second, i was expecting that you would make Principal DB unavailable (drop,offline etc) and Auto Failover would happen. Would this happen?
-- In 'thoughts'...
Thank you! really a clear explaination!! Regards!
nice video
Thank you!
dear
I would like to ask..when i start mirroring it gives an error says database can;t be opened..it's in middle of restore...any ideas?
Nice bro
Thanks
Good job
can i use this on two different server with different ip address?
hi. Assume that witness and principle instance reside at server 1. And mirror instance at server 2. When Server 1 failed, an application sql connection string is point to witness instance. Will the application able to access the mirror database at server 2?
I get 927 error, it says middle of restore. I m using 2016 Ssms
do we really need to have the shared drive between principal and mirror server for backup and restore database.
or can we configure mirroring without having shared drive like just by transferring db backups from principal to mirror server and restore it on mirror.
Is shared drive mandatory between these 2 servers for db backup and restore ?
On principal server it showing port number 5022 and mirror server its showing 5033. Ho to fix the issue??
Hi , I have some question to ask about instance database in sql server 2016.
I want to do standby server but i am not sure which technology that i should do between Mirror and Replication.
Do you have any suggestion for this point ?
Hi Bro,
Thank you for your sharing. But I restored my DB with No recovery. When I set up Mirroring. It showed 'Error 927. It's in the middle of a restore'.
Why? Thanks!
+Nexus Roc it must still be applying last transaction ( maybe its big tran) ... give it a little time and should be able to bing it online - you can check lsn number from msdb on target server (did you stop mirroring before try to bring it online?)
Hi,
Thank you for your reply. I re-installed SSMS 16.3.1 and it's working fine right now. Before this, I just upgraded my SSMS to 17.1. That's very ridiculous issue. Anyway, thanks again. I learn lots from your video.
Have a great weekend!
I am facing the issue while configuring the Database Mirroring like "TCP://......:5023" can not be reached or does not exist. check the network address name and that the ports for the local and remote endpoints are operational.(Microsoft SQL Server , Error : 1418). please suggest me what i have to do..please its very urgent.
+Rajeev Ranjan can you please see on your source if end points are created? More likely they are missing - also check permissions of the service accounts on source and destinations.
thanks a lot.. I resolved my error.. Can you check this video ruclips.net/video/Lsa3o8mgnuc/видео.html , its created by me for the database mirroring
Check if TCP/IP is enabled in the SQL Server Configuration Manager \ SQL Native Client 11.0 Configuration \ Client Protocols
Hi TechBROTHERSIT
I would like to know how to create a new instance on SQL SERVER please
Thank you
Dear sir when i configure sql server 2016 for mirroring we find the error:
database cannot be opened. it is in the middle of a restore error no 927. Kindly help me.
This is SSMS issue, try using SSMS 2016 or 2014 for configuring it. I have not tried if latest SSMS causes that issue too.
Did it work?
Hi Bro,
I have another question about mirroring. DO you know why Microsoft will not support mirroring in the next version? After this, we just use Transaction Log Shipping to keep high availability?
+Nexus Roc Availability Group is taking over - we really don't need mirroring if we use Ag feature - I suggest mirroring to my clients only if they are running 2008R2 and below - all other version I would suggest using AG for your DR scenarios.
Thank you for your information! Have a nice weekend!
Thank you. Have a nice weekend!
Hai
In 2016 SQL SERVER MIrroring Is Not Working.
IS There any command To Run To work Mirroring..'
What’s the error are you facing? Make sure you don’t use SSMS 2017 please use 2014 for this setup once done you can use latest ssms
I cannot start mirroring, I have error 927 the database is being restored
Please use SSMS 2016 or lower for the setup, you can manage using higher versions.
I just tried this and i receive an error that the database cannot ne opened because it's in the middle of a restore! :( Why were you able to?
Please do not use SSMS 2017 - use ssms 2014 or 2016 - you should be fine.
It’s a big in SSMS 2017 if that’s what you are using - if you still face the error, please let me know.
