Requests and hosted by my favorite and inspirational Brent Ozar.Here is my bug report https connect.SQLServerfeedbackdetails3.It happen one of my production database, when I tried to remove the database from always.ON and other important databases went recovery pending and inaccessible.I have no idea what happened to all other databases, then I came to know it is a bug.The issue is when the database removed from the primary replica, with the secondary disconnection the higher database IDs on the secondary went into NOT SYNCHRONIZED and RECOVERY PENDING state, but the lower database IDs are good and synchronous state only.Im currently working as a SQL server DBA in one of the top MNC.Im passionate about SQL Server And Im specialized in Administration and Performance tuning.Im an

corruption DBCC check.DB for Very large database.We know SQL server data is stored in a filesystem storage.There has been always an IO input and output interaction between SQL server and storage subsystem both in the memory and disk.IO subsystem plays a major role, 9.IO subsystem Such as in the controllers, disk and driver level etc.In this post, I am sharing few things.How important is the CHECKDB.How to fine tune and use the check.How To Start Sql Service Manually Backup To IcloudDB for VLDBs.Methods of troubleshooting the corruption issues.Storage VM Admin Sent a graph states that, IOPS for the server is very peak weekly once between this day to day.DBA Admin Yes, we are running the check.DB job for VLDB weekly once between the days.It might cause, since it reads every allocated page in the database will take a lot of IOPS.Storage VM Admin It is a huge spike to the VM machines, can you disable for next week, if it reduces the IOPS and you can run it monthly once.DBA Admin No, this is very important for the data consistency and integrity check.Changed the check.DB to monthly once.All are going good, but there was a day, when the database reported a corruption.Now, what Restore the latest full backup with different database name, run the check.DB, surprise, that is also got corrupted.The corruption is severe either restore from backup or run repair allow data loss.The application will not work for repair allow data loss.We used another method of application that is a different story.The point is check.DB is very important, run at least before taking a full backup, it gives us a minimum level of production from the corruption.Best options for very large database VLDB.The database is 1.TB and the check.DB is running more than two days, how to reduce the run time.I had this for one of my database.I used different approach and got some good point from Paul Randal.Me My 1.TB database check.DB runs more than two days, it took 8 hours if I excluded the non clustered index.Hope, I can go with it, since I can recreate the NCI, if it gets corrupted.A response from Paul Randal Sure you can do that, but you wont know when your indexes are corrupt until queries start failing or getting wrong results.I dont recommend it.Backup, copy, restore, checkdb is the way to do it, or split the checks up using DBCC CHECKTABLE.Initially, I skipped the non clustered index, it can be drop and create in case if it gets corrupted.This will definitely reduce the run time.My case From 2 days to 8 Hours.Use Ola Hallengren check.DB script.It has more parameters you can use those.If you have a 1.TB database with a table 5.GB, if it is not critical you can skip that, since its a very old dump data and can import from the original source file.It is different case3.Split check.DB option is good for VLDBs.It has two methods.File and filegroup check.DB 2.Default, one MDF filegroup check.DB.Method 1 File and file group, you can run DBCC CHECKFILEGROUP.It is easy one and you need to make sure the size of the files needs to run each day.If the size is not same for all the files, then plan it to combine and run accordingly.Method 2 Single file VLDBs, use a split check.DB.Figure out your largest tables by number of pages and split the total number into 7 buckets, such that there are a roughly equal number of database pages in each bucket.Example Find out the larger tables in the first list and the remaining tables in 2, 3,4,5,6 bucket and need to run dbcc per the above post.If you have a larger table, it has 1.Pages, all bucket should almost equal to 1.One more interesting case by Argenis Fernandez.A non clustered index with sparse column, make check.DB run time worse.A post by Aaron Bertrand covers with trace flag usages and more.You can use and combine the 1 to 5 methods for the VLDBs, it will reduce the time.Test and make sure which option is good for your business and use that one, but do not leave the check.DB run.Steps to identify the corruption Step 1 Run the DBCC check.DB at least weekly once in the agent job, this will report the corruption.Step 2 Check the error logs daily, if you have a centralised server automate an email by checking an error log every one hour for a critical error report OR create an alert notification by using an operator.Note the database name from the error message, if any corruption in the database.Step 3 If you find any error, run consistence check with an option to get an exact corruption message DBCC checkdb DBname with noinfomsgs,allerrormsgs.The check.DB will give you the error message with hint that, what option can fix this corruption, it just a suggestion given by SQL server, some memory level corruption cases, a recycle fix it without an actual REPAIRALLOWDATALOSS run.But, you should know, which case needs a reboot.Step 4 If you have good experience in the error and you think you can fix without a data loss, you can try.Like a non clustered index corruption drop and create, some memory corruption recycle of the SQL service etc.There are cases, a recycle of SQL service fix the inconsistency.My case I had a database shows online
