SQL 2012 :: Existing Replica MDF File Size Increased In Size Than New Replica Install
Apr 14, 2015
Here are my scenarios:
We have an application with replicated environment setup on sql server 2012 . Users will have a replica on their machines and they will replicate to the master database. It has 3 subscriptions subscribed to the publications on the master db.
1) We set up a replica(which uses sql server 2012) on a machine with no sql server on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 33gigs and ldf has grown to 41 gigs. I went to sql server management studion . Right click and checked the properties of the local database. over all size is around 84 gb with little empty free space available.
2) We set up a replica(which uses sql server 2012) on a machine with sql server 2008 on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
3) We set up a replica(which uses sql server 2012) on a machine with sql server 2012 on it. We have dropped the local database and recreated the local db and did the initial synchronization using replmerge tool. The mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
Why it is allocating the space differently? This is effecting our initial replica set up times.

I have 2 SQL Server replicas configured on SQL Server 2012 AlwaysOn. e.g. SQL1 & SQL2.
I have configured backup job on both SQL Server with the following statement. and the job occurs every 10 minutes.
•declare @DBNAME sysname,@sqlstr varchar(500)
set @DBNAME = 'dba'
IF (sys.fn_hadr_backup_is_preferred_replica(@DBNAME)=0)
BEGIN
--Select 'This is not the preferred replica, exiting with success';
[Code] ...
I turned off SQL2 for Windows maintenance. So there is only SQL1 is online. Afterwards. I checked the backup folder and didn't see any new backup files was created after SQL2 was offline. I rerun the job. It still doesn't backup database on the Primary Replica. Then I searched on SQL Server Book online. It says
Prefer Secondary
Specifies that backups should occur on a secondary replica except when the primary replica is the only replica online. In that case, the backup should occur on the primary replica. This is the default option.
According to what it says, it should backup on the Primary Replica.

I installed sql 2005 a while back. Then I recently found out my file system was fat32 (I don't understand why the hardware people did this...) and I had to convert to NTFS. Naturally the sql service no longer worked so I uninstalled inorder to reinstall now I can't reinstall it I keep getting this message
native_error=5039, msg=[Microsoft][SQL Native Client][SQL Server]MODIFY FILE failed. Specified size is less than current size.
I'll try to post the full log in a new post.

I am trying to resize a database initial log file from 500M to 2M. I€™m using€?
ALTER DATABASE <DBNAME> MODIFY FILE ( NAME = <DBLOGFILENAME, SIZE = 2 ) "
And I'm getting "MODIFY FILE failed. Specified size is less than current size." I tried going into the database properties and setting the log file to 2M, but it doesn€™t keep the changes.
Any help with this process?

I have an availability group with read only replicas, readable secondary set to yes and allow all incoming connections. I have also configured the read only routing (at least I'm pretty sure this is correct).
If I login to SSMS with a user in the sysadmin role I can view the objects in the read only replica database. If I login with a user in the public role I'm unable to get past the obvious error:
"The database databaseA is not accessbile. (ObjectExplorer)"
I've also tried adding the "ApplicationIntent=ReadOnly" option.

I would like to setup replica for one of the databases for reporting. The current environment is a 2 node cluster(active/passive). I would like to add a 3rd node that can server as a secondary replica. The secondary replica will be on asynchronous commit mode.
The database that needs to have alwayson setup has column level encryption enabled.
* Do I need to backup and restore the service master key on secondary server in order to have the column level encryption to work on secondary server?
* What would be preferred Quorum settings?
* What is the setting for 'readable secondary' for primary and replica db?
* What should be the setting for 'Connections in Primary Role' for primary and replica db?
* We are trying to setup without a Listner. Do I need to setup AG Listner? Can the application exclusively use the [secondary instance name].[replica DB name] without a listner?

Environment:-
Windows 2012 R2,
SQL 2012 (Primary Replica)
SQL 2012 (Seondary Replica)
SQL 2012 (Secondary Replica over WAN site)
There are database replicating on three SQL servers. WAN line is having performance issue because of limited bandwidth I have to remove SQL secondary replica over WAN site temporarily and add it again later when the WAN line is upgraded with between bandwidth What is the best practice to remove secondary replica and replicating database and add later from SQL management studio without interruptions on databases?

I have an AlwaysOn Availability group configured between 2 nodes (Synchronous)
Automatic failover was working fine until recently
I can failover between the nodes manually but automatic failover doesn't seem to be working. In my earlier test, I would shut down the SQL Service on the primary and within seconds, the secondary replica would take over. Recently I have performed the same test and the secondary replica enters the resolving state and the DB in unavailable.
I have tried everything here: [URL] ....
The only change I made was changing the availability mode from Synchronous to Asynchronous - Could that be the cause?

After failing over to the DR replica. All databases are out of sync. DR replicas were setup as async the other 2 are set up as sync. Is this by design. No data has been updated to any of these as they are test dbs. So all dbs should be the same, no data loss.

What happens when an automatic failover occurs, in a two server AlwaysOn Availability Group configuration, where the secondary replica is configured as read-only?
Will it only allow read-only connections, or will it become read-write and can accept INSERT, UPDATES and DELETES when assigned the new role as Primary?
Is it correct that adding a third server/node, that just acts as passive and should be used for automatic failover, to support true HADR, would NOT need another license .. and that licenses would only be required for the previous Primary and Secondary (Read-Only) replicas?

We have a vendor that is exposing our database via a High Availability replica. They are geographically far away from us though so we would like to extract portions of the database over to our side for our reporting /warehousing purposes. I was curious if it is possible to setup snapshot replication on a high availability group?

I was working on a job to send me info each morning about database file free space and was noticing some odd things when looking at the log file VLFs for one of my databases in an AlwaysOn availability group.When I run DBCC LOGINFO on the secondary replica for this database, I get what I expect and most VLFs have a status of 0 (indicating the VLFs are reusable or unused). When I run DBCC LOGINFO on the primary replica, all of the VLFs have a status of 2 (active or recoverable).
Since log backups on the secondary replica in AlwaysOn still truncate the log in the primary replica, I would expect that the VLFs in the primary replica would also be mostly in a reusable or unused state. My log file sizes are the same size on each server and my backups are completing successfully. what might be causing the VLFs on the primary replica to have a status of 2 in DBCC LOGINFO when taking log backups from the secondary replica?

Does any one know what could be making the size of a backup get so big in SQL server?
I noticed if you back-up the same database in Enterprise Manager over and over (without making any changes to the database), the size of the backup gets bigger and bigger. To get around this I simply erase the backup and create a new one.
Now I'm experiencing the same kind of problem, different situation. I decided to make very few changes to my database. If anything, I shrunk the size of the tables and stored procedures.... Now all of a sudden my database backup is 7 times larger.
What could be increasing the size so much, if I haven't increased the amount of tables or stored procedures?
What is the log file about? Mine is huge? Is there a way to reset it or clear it?
any help would be great.
Thank you,
Alec

I'm having a problem. When I use the SQL query to make a backup of the database, it worked fine. But everytime I use it, the backed-up file's size kept growing in size. Say I have the file, test.bak whose filesize is 450 MB then I run a new backup to overwrite the existing test.bak file, it just end up as 900 MB. If I run it again, it become 1350 MB and so on.
Is there a way to prevent that from happening?

Hi,
I was running out of space and thus deleted some rows from a table. To my surprise the db size increased. I then shrunk it to bring it back to what it was earlier.
When i deleted some 5000 rows, some space must have been released. Where did the space go and why did the db size increase after deleting the records?
I thght it might be log files..but db is set to Simple Recovery which does not utilize a Log File.
Any reasons?

Setting up a test AlwaysOn Availability Group for one database.
However, whenever I restore the database to the replica server and join it, it ends up with my user account as the owner of the database.
Obviously I do not want a user account as the database owner, but since it is read-only I cannot modify it directly. If I were able to fail the AG over to the replica, I could change the owner then, but I cannot due to business requirements. this AG is to essentially serve as a replacement to log shipping.
I tried doing the backups and restores using EXECUTE AS login = 'sa', and yet it still shows up as my user account.

I need to write a process to get file size in kb and record count in a file. I was planning on writing a c# console app that takes the file path and name as a param however should i use a CLR?
I cant put a script in the ssis when it's bringing the file down because it has been deemed that we only use ssis for file consumption.

I was having interesting discussion on estimation of log file with a fellow collegue who happens to be quite knowledgable as well.
He told me if we identify the most frequently hit tables for a database and then (sum their sizes * 1.5) for OLAP we get rough estimate for disk space to be allocated for log file.

finding the database size from the backup file.I have SQL 2012 backup file, is there any way to find the estimated database size from the backup.I tried restoring , i got an error saying " no space need additional xxx bytes " ...does this error gives the exact space needed to restore ?
One more question....one of the backup file size is 7.2 GB, when i try to restore it ....it throws error saying it needs 292GB extra space while only 100 Gb is available. How come 392 Gb sized database becomes 7.2 Gb .bak file ?

I have a log file that is approximately 50 GIG. I backed up just the log and the file size of the .bak is 192 GIG . Why is this? Shouldn't it be closer to the 50 GIG.
Normally I wouldn't let log grow this much. But we are in process of getting new server up and running and don't have backups going yet. They are working on getting that up and running this week.
So I did a log backup to give me back some log space for now but was concerned when I saw the size of the .bak file.
When I view media contents of the backup device it shows one tranaction log back up and size of 192 GIG.
What is up with this. I know in SQL 2000 the log backup files where never this big. they were about the size of the log itself.
Any ideas?
Stacy
