SQL Server 2008 :: Using BCV Split Mirror Copy And Restoring Databases?
May 1, 2015
I was contacted by the SAN team to test backup/restore of larger databases using a split-mirror backup (BCV) or clone that is taken from production db server and copied to another sql box. They want to use this process once a week. I see the mounted drives with the data/log files. All looks good. Initially I attempted to attach the databases and received (Unable to open the physical file db.mdf Operating System Error 5 Access is denied). I manually granting SQLServerMSSQLUser$<computer_name>$<instance_name> on all of the physical files 20 total. That worked.
Since this will be weekly, the SAN team performed the copy again and now none of the databases can communicate with the newly copied files. NTFS permissions need to be set again. I'm getting (Operating System error 21: the device is not ready). Is there something that I'm missing in this process how the vendor BCV clones the data and SQL communicates with the copied files as I was thinking it would be more automated process?
I am working on a task. Currently we are taking a database backup and keeping that backups in a folder. The backups doesn't have time stamp on it. My task is need to get the latest backup and copy that backups into some other server and then restore the database from there.I am planning to create SSIS package.Do we need script task for this task.How to get the .bak with latest create or moidified date. For now we doesn't have timestamp so need to go based on modified date?
Hi guys, right now I am having insufficient hard disc space at the secondary server (Mirror side) due to the large db that I have. Therefore, I get a new HDD on the server (Assuming located at drive G) and would like to shift the current mirroring db to that new drive. Is it possible for me to do that ? Hope able to get any suggestion from here ASAP. Thanks.
We currently use a split-mirror backup strategy for our Sybase database, which has a "quiesce database" command to suspend all transactions. By quiescing the database before splitting the mirror, we suspend all transactions to ensure we get a stable backup of the environment. It works very well for us and I'm trying to understand how we could implement this with our SQL Server 2005 DB.
(I'm aware of SQL Server mirroring and that there are other ways of possibly backing up the DB. In this post however, I'm only interested in how I would make the split-mirror strategy work if I wanted to pursue it. I'm trying to avoid paying for software that uses the VDI as it's quite costly.)
Can someone help me with how I would accomplish a split-mirror backup strategy in SQL Server 2005 (without using a vendor's software that uses the VDI)? I have to imagine there's something similar to the "quiesce database" command in SQL Server...
I recently was given control of an SQL server that stop working. We had no past backups of the database and the only file we had was the .mdf I decided to install a fresh version of SQL 2000 on another server and created a database using enterprise manager with the same name as my database called SWATraining
I then stop the sql server
the first thing that I notice is that the .mdf that enterprise manager created had _DATA at the end of the name. Thus I renamed the the orginal .mdf SWATraining_Data and
copied it to the C:program filesmicrosoft sql servermssqldata when I started SQL the database was greyed out and had (suspect)labeled
How can I recover the database when the only file I have is the .mdf file??
Server: Msg 5172, Level 16, State 15, Line 1 The header for file 'C:Program FilesMicrosoft SQL ServerMSSQLDataSWATraining.mdf' is not a valid database file header. The FILE SIZE property is incorrect.
I am trying to break apart a list of filenames that was inserted into a database. It only breaks out the first one then moves onto the next record. If I do them individually then seem to work but not the whole table when queried. I need to break out each file into a temp table then insert them into a documents field in a database.
my filenames look like so and can have from 1 file name to 10 file names in the string.
This is my current method, I needed to create a cursor around it to go through all the records, split out the filenames and insert into a temp table. But if there is a better way ill do it. The problem with this is only the first file is getting inserted into the temp table and nothing else even if the filename has 4 files in it.
Create table #tempFiles (OldStrId int, OldPercent int, strfilename varchar(max), RequestId int, OblId int) declare @OldStr int, @OldPer int, @FileName varchar(max), @intcount int; Declare filenames CURSOR FOR Select intSTRBonusID, intPercentID, strFileName from tblSTR where strFileName > '' UNION ALL Select intSTRBonusID, intPercentID, strFileName from tblSTRHist where intPercentID in (61,62) and strFileName > ''
I've a table that has salescode(124!080) and salesamount(125.65!19.25) and I need to split the columns. Salesman(124) has commission(125.65). Here is the DDL:
USE tempdb; GO DECLARE @TEST_DATA TABLE ( DT_ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED , InvNoVARCHAR(10) NOT NULL , SalesCode NCHAR(80) NOT NULL , Amount NCHAR(80) NOT NULL
I need to split the amount equally into 12 months from Jan 2015 through Dec 2015.There is no date column in the table and the total amount has to be splitted equally.Guess I can't use Pivot here because the date column is not there ...How can I achieve this ?
CREATE TABLE #tbl_data ( Region Varchar(25), Amount FLOAT,
I wonder how do I shrink log file in a specific database which in Mirror/Synchronized/Restoring state..So that database is in Mirror server ( High availability ).
I am working now on optimization of an update query for a particular table and I want to measure the number of page splits after each update. How to check it?
I am trying to split the annual cost into monthly numbers based on the contract Period.Since the contract period varies from company to company not sure how to implement the logic.
Our front end saves all IP addresses used by a customer as a comma separated string, we need to analyse these to check for blocked IPs which are all stored in another table.
A LIKE statement comparing each string with the 100 or so excluded IPs will be very expensive so I'm thinking it would be less so to split out the comma separated values into tables.
The problem we have is that we never know how many IPs could be stored against a customer, so I'm guessing a function would be the way forward but this is the point I get stuck.
I can remove the 1st IP address into a new column and produce the new list ready for the next removal, also as part of this we would need to create new columns on the fly depending on how many IPs are in the column.
This needs to be repeated for each row
SELECT IP_List , LEFT(IP_List, CHARINDEX(',', IP_List) - 1) AS IP_1 , REPLACE(IP_List, LEFT(IP_List, CHARINDEX(',', IP_List) +0), '') AS NewIPList1 FROM IpExclusionTest
I am trying to join two tables and looks like the data is messed up. I want to split the rows into columns as there is more than one value in the row. But somehow I don't see a pattern in here to split the rows.
This how the data is
Create Table #Sample (Numbers Varchar(MAX)) Insert INTO #Sample Values('1000') Insert INTO #Sample Values ('1024 AND 1025') Insert INTO #Sample Values ('109 ,110,111') Insert INTO #Sample Values ('Old # 1033 replaced with new Invoice # 1544') Insert INTO #Sample Values ('1355 Cancelled and Invoice 1922 added') Select * from #Sample
This is what is expected...
Create Table #Result (Numbers Varchar(MAX)) Insert INTO #Result Values('1000') Insert INTO #Result Values ('1024') Insert INTO #Result Values ('1025') Insert INTO #Result Values ('109') Insert INTO #Result Values ('110')
[Code] ....
How I can implement this ? I believe if there are any numbers I need to split into two columns .
I am using SQl Server 2012 Database Mirroring with around 40 gb as mdf and 1 gb as ldf. Now my ldf size increased . How to reduce ldf size while mirror enabled with mirror server and witness server. Can shrink the ldf with mirror enables.
I have another question : 1) Restoring SQL Server Databases after uninstalling and reinstalling SQL Server.
Two days ago there was some problem with Norton Antivirus, so Windows 98 restored itself to a previous state. The SQL Server name was not available when I tried to start again, so I had to uninstall and reinstall SQL Server. I started a new Database just a week before this happened (the change from Access to SQL Server as I stated in the other thread http://www.dbforums.com/showthread.php?threadid=987880) and after reinstallation I could not access the Database any more - even while it is in the Data directory. I did not have any backup to restore from - I just started creating tables, so there was only the Log file created and the MDF database file. I tried to import it for a while to the new server, but as the database is not shown in the new server, it was unable to import like I hoped. So how do you restore it back to SQL Server when you have no backup and only the (undamaged) MDF database file if you only have one server? I had to recreate the Database from scratch again - I don't want it to happen again.
if you can restore a database to Server B using Server A as the service. Meaning we would issue the command on Server A but somehow point to Server B as where we want the restore to happen.
The backup file would be in a location independent of both servers.
I am restoring a database with 10yrs worth of data which have monthly partitions but i would like to keep only 5yrs of data after the restore is done, what is the best/faster approach to delete the 5yrs data without deleting the partitions as that may cause the db in accessible.
I have a database with deployed CLR assembly on SQL 2008. I recently took a backup for the database and restored it on SQL 2012 server. Everything worked fine except very strange working of CLR assemblies functions.The result of the function is very odd. It manipulates the numeric string and return the result. It is returning very strange result on SQL 2012 as compared to SQL 2008.Example SQL 2008 ManipulateString('1234') returns 2345 On SQL 2012 the same call returns 1155.I am also trying to deploy the same assembly to SQL 2012 server database. I have successfully register the assembly, but the database do not list the exposed methods.
Deciding whether or not to use a CTE or this simple faster approach utilizing system tables, hijacking them.
SELECT s.ORDER_NUMBER, s.PRODUCT_ID, 1 AS QTY, s.VALUE/s.QTY AS VALUE FROM @SPLITROW s INNER JOIN master.dbo.spt_values t ON t.type='P' AND t.number BETWEEN 1 AND s.QTY
Just wanted to know if its okay to use system tables in a production environment and if there are any pit falls of using them ?
I have three win2k8 r2 servers. Â 2 are running SQL 2008 r2 and are mirrored. The 3rd server is a witness server. Every so often we get errors and failovers of the mirror. The communication errors are between the witness server and sql servers. No errors between SQL servers. There seem to be no network issues and happen randomly.Â
Event id 1474 and 1479. The mirroring connection to "TCP://witnesssrv:5022" has timed out for database "DB" after 30 seconds without a response.  Check the service and network connections. Database mirroring connection error 4 'An error occurred while receiving data: '64(The specified network name is no longer available.)'.' for 'TCP://witnesssrv:5022'.
Since,You cannot mirror the master, msdb, tempdb, or model databases.What will happen if i create new login,change existing security profile and new jobs,change of existing job on princicpal db. how these will be mirrored to other server and in case failover, how it will treat.
I need to recover some data in a table but i'm not 100% sure the right way to do this safely.
I'll need to query the two tables to compare the before and after but how do i go about restoring/attaching the backup database to SQL without causing conflicts?
If I restore, I assume this would just overwrite which is obviously the worst thing that can happen. if i attach the backup, how does this affect the current live DB? how do i make sure that it's not getting accessed and mistaken for the live DB?
Copy objects and data between SQL Server databases " Display the Select Objects to Transfer dialog box, where you can specify both objects and data to copy, if both the data source and destination are Microsoft® SQL Server™ databases. The objects you can transfer include tables, views, stored procedures, defaults, rules, constraints, user-defined data types, logins, users, roles, and indexes. You can transfer objects only between multiple instances of SQL Server version 7.0, from an instance of SQL Server 7.0 to an instance of SQL Server 2000, and between multiple instances of SQL Server 2000. "
can I apply "Copy objects and data between SQL Server databases" to run in two different sqlserver 2000 ( not an instance ) . what I mean is I have two different sql servers located in two different locations( I am not using an instance installation) can I still run the copy and get an identical database in both servers. Q2. if I have two sql server 2000 with different collations (one is binary and the other is the default) will I be able to run the copy wizard and still have an identical copy of sql server in both servers.
I personally tried to run the copy wizard and IT NEVER WORKED FOR ME and I really do not know the reason.
I have a 2 node cluster having 4 cores each wherein having 3 instances of SQL 2008 R2 enterprise comprising of 60 databases, 20 on each instance. I need to setup mirroring for each of the databases to a secondary server having 4 cores and 3 instances.
What i understand is that in this case the mirror server will be providing max of 512 worker threads and the 60 mirror databases would consume 240 threads.
What all needs to be checked for looking into the feasibility of going ahead with a async mirror setup as mentioned above.
I am using a SQL Server Agent jobs that run each morning to update the records in a table to match what they should be for that day. I built them and tested it using a test table called "testtable1". It worked fine. But when I switched over to our production table, it fails saying the table has to be decaled. What would be the difference. The production table has a "@" in front of the name, is that causing issues?

I have around 600 databases in my server, a user need select access of all the databases. will i have to go one by one in all the dbs and create that user and give datareader role to him. or is thr any shorter way to do so????
1.Is it OK to shrink Master, model ? the transaction log for those databases are full . 2.Is it OK to set the Recovery model of Database MODEL as SIMPLE ? at the moment it is in FULL recovery model and the transaction log is Full too
Script to find a value in all databases ? for example I want to find a value contain word “ SQL†in all databases so I will get the information in which database and which table it exists.
My script is only for finding a value in one database.
