Can't remove IP?!?!? What the ..

Hi,

I am using SQL2014 with HA/AG groups and was adding an extra listener when I used the incorrect IP address. 

I had thought the 'remove' button would work, but it does not. Also I tried deleting it manually:

[quote]
delete from sys.availability_group_listener_ip_addresses where listener_id = '26d37cdb-5a6f-43a0-ab0c-f4343eeac0f2' 

delete from sys.availability_group_listeners where group_id = '6B060505-CDDC-44B6-A9AD-38FC6AD4A7AA'[/quote]

Ad hoc updates to system catalogs are not allowed.

I attached an image.

How can I remove the invalid IP?

Hi,

SQL Always On

Backups taken on a replicas will not show up in the MSDB database backup tables of the primary server (or other replicas), as they don’t share an MSDB database.

Then where can i find the backup/SQL Jobs and so on information?

SQL 2008R2 Failover Cluster without File Share

October 14, 2015, 1:37 pm

We are looking to set up a failover cluster for our SQL 2008R2 database. To accomplish this, we have 2 servers, both equipped with Fusion I/O cards that will both have identical copies of our production databases on them.

From everything I've read, we're supposed to set the servers up so they are both pulling the databases from a shared file storage of some sort. We intended to have both servers simply run the databases from their respective Fusion I/O cards rather than from a file share.

Clustering seems to be the correct choice for a high availability SQL setup, given the "LooksAlive" and "isAlive" checks it makes, but if the shared storage is a requirement, we may need to consider an alternative solution.

Given that we only really need the HeartBeat network functionality and don't need any shared storage, can we still use a Failover Cluster for SQL?

SQL Server Log Shipping 14420, 14421 False Error Message

I have set up log shipping on a SQL 2014 server to copy data from a primary to a secondary server. This is all working correctly backing up, copying and restoring however the alerting which is configured to run to the secondary server is reporting that the last backup time is the time of the initial backup full before log shipping starts. This is the information that is reported when I query the msdb.dbo.log_shipping_monitor_primary table. Consequently when the monitoring alert runs, it reports:


Msg 14420, Level 16, State 1, Procedure sp_check_log_shipping_monitor_alert, Line 61
The log shipping primary database XXXXXXX.xxxxxxx has backup threshold of 60 minutes and has not performed a backup log operation for 1120 minutes. Check agent log and logshipping monitor information.


SQL server was originally installed before the server was renamed to its current name however I have renamed the instance and all queries of the database (e.g. SELECT @@SERVERNAME) return the correct servername.

Cannot connect to VLDBATEAM.

ADDITIONAL INFORMATION:

The secondary replica that you selected to become the new primary replica does not belong to the specified availability group. A possible explanation is that the replica has not been joined the availability group.  (Microsoft.SqlServer.Management.HadrTasks)

Compatible Development Platforms?

October 15, 2015, 8:24 am

As understood, AlwaysOn Availability Groups supports multi-subnet failover as long as the application in question supports:
SQL Native Client 11.0 ODBC
ADO.NET with .NET Framework 4.0 (Update 4.0.3)
Microsoft JDBC driver 4.0 for SQL Server
and the app was developed on:
.Net 3.5 SP1 or higher
(resourse = http://www.mattmasson.com/2012/03/alwayson-multi-subnet-failover-and-ssis/)
This particular article has been a valuable resource for testing databases and their new or old supporting apps.
I've devised a comfortable mix of "supported" & "unsupported" listeners, depending on whether apps were created
on platforms that support "multi-subnet failover = true".

I have one app that was developed on Microsoft Dynamics NAV 2009 SP1.
I haven't found any articles that mention the Microsoft Dynamics NAV 2009 SP1 platform and AOAG in the same sentence.
I guessing that it doesn't support multi-subnet failover ?

Hi folks,

We've just started using AlwaysOn High Availability and run into a wierd issue. I have 1 particular database that is not syncing data to the secondary replica. But when i look at all the dashboards, everything is green, they all say synchronised - but if I query the data they are not.

The database has additional sql transactional 1 way replication a different server which i was wondering if was causing any problems, but it's working ok,

I'm just wondering if there's any other more detailed logs i can check to see why the data is not flowing. The availability dashboard and it's event log all says ok.

Thanks

SQL Server 2012, SSMS won't show bak files or even folders, using enterprise admin account?

I'm working on a newly installed windows 2012 R2 server which has SQL Server 2012 and SSMS installed on it. What has been odd is that when I open the "restore database" dialog, in the "Select Backup Devices", "Locate Backup File" dialog, only the immediate folders off of the root of the E: drive are visible. E: is where sql server data and backup files are stored.

The account I am logged in with is supposed to have Enterprise Admin rights. How is can I not see these folders and files? The files are certainly there and are visible to me on that login with windows explorer. I am able to backup via SSMS without issue. When I look at the folder's permissions everything seems normal. If I add "Everyone" to that folder's permissions the folders and files become visible. The SQL Server service is running on the NT Service\MSSQLSERVER account, which is normal for my other installations of sql server. Can anyone suggest what the issue is?

Hello,

I have log shipping setting up on my production going to my DR server with every 15 min of Tlog backup , but after doing some online searches about this I still cannot figure out why the transaction log file of the database does not reduce\truncate? It keeps growing. I made sure there are no active or open transactions. Is there any way to check the transactions open during the tlog backup happend? But still the log file is 70gb and does not truncate after the 15 min log backups..

I did a lot of searching about this, but could not find a solution, please help me on this.

Thanks

AlwaysOn Estimated Recovery Time (seconds)

Hi All,

Estimated Recovery Time (seconds) is not matching with actual fail-over recovery time. Is the two process different? Normal Redo catch-up and during a time of failover recovery?

Estimated Recovery Time (seconds)  -> 7000
Redo Queue Size -> 12 GB
Normal Redo Catch-up -> 2-3 hours
Manual Failover Redo Catch-up -> 2-3 minutes and database was online and accessible

We saw this behavior in non-prod VM machines and identified the process and fixed it which was generating huge REDO. But the recovery time number (7000 seconds) was a concern if we get such a real time scenario in production. So we tried a manual fail-over repro-ing the REDO scenario, but the secondary came online Synchronized and was accessible within 2-3 minutes.

Thanks,

Availability Group Listener - Targeting Incorrect Node

Hi Guys,

We have a multi-subnet cluster and trying to add a listener but the following error keeps popping up:

Msg 19456, Level 16, State 0, Line 1

None of the IP addresses configured for the availability group listener can be hosted by the server 'XXXXXXXX'

The cluster node referenced in the error is not an owner for any of the IP address ranges selected for the listener. How can I prevent the creation of the listener from targeting this new server? This node was recently joined to the cluster. Validation of the cluster is fine.

Any ideas where to look?
