Store Remediation Scripts

Below is the list of items which needs to be checked and deployed before the SQL Store goes live. Theseare done to ensure that the SQL server is stabilized and runs smoothly once it’s live. Database team will

be providing the required scripts for stabilizing the environment.

1. Check the patching level on Store Server.

Latest patch must be applied on store servers, this patch is Microsoft recommended ones and is applied

to ensure that database server is functioning as expected.

IT IS Database team will be applying these patches coordinating with IT Release team. Store Build Team

needs NO action on this Item.

2. Verify location of Data and Log files

For any new database created, ensure that all the data and log files are created in respective mount

points in F drive. In past, Database team had noticed that these were pointed and created on drive E.

These are mainly found on SAP instances, an updated script has been shared with concerned team and

new databases will now point to right drive. Database team will however cross verify it before the server

goes live.

3. Maintenance Plans

All the Store servers should have maintenance jobs created on them in order to ensure that the Indexes

are optimized and updated on regular basis; this will make sure DML and DDL statements on SQL server

to perform better and have faster responses to application queries. Below is the list of maintenance

activities which needs to be done on each store server. These will be done by creating an SQL Agent Job

on SQL Server.

Index Rebuild

Index Re-Organize

Update Statistics

Database Integrity Check.

Store Build team will be creating these jobs as part of then build of any Store server, using the

attached scripts.



Project ID: 1000047610 Ver: 1.0


a)

MX_Store_DailyIndexMaintenanceJob_DBA

This is index maintenance job which run daily and rebuild/reorg index based on fragmentation levels, if

fragmentation is beyond 30% then do rebuild else reorg. After rebuild activity it does update statistics.

For any queries about this job consult [email protected] team

b)

MX_Store_WeeklyCheckDBMaintenanceJob_DBA

This is Database integrity maintenance job which run weekly once and check database integrity. For any

queries about this job consult [email protected] team

Steps to follow to create these maintenance plans

i)

Login to Store server which is been just built.

ii)

Go to Start -> All Programs ->MS SQL Server 2008R2->SQL Server Management Studio

iii)

Provide the server name to login to e.g. VWPRXXXXXSQLPR01\A1B and click Connect

iv)

Once logged in Click on New Query on top left corner of the window.

v)

Simply open or Copy and Paste the script and click on execute.

vi)

The jobs now will be created successfully, this can be verified under

SQL Server Agent -> Jobs Column

NOTE: Same steps needs to be repeated on all instances. Since SAP has 3 instances, above query has to

be executed thrice, once on each instance.

If any errors or failures while creating Jobs, Please contact [email protected]

4. Max Memory settings

SQL server max memory settings should be set to max memory of 2GB and min memory to 1MB, this isalready been done as part of Store Build process, Database has to cross check it again before Go-Live of

the Store Server. If this has been missed out by Store Build team, below script can be used to make this

setting.

sp_configure 'show advanced options', 1; RECONFIGURE

GO

sp_configure 'min server memory', 1;GOsp_configure 'max server memory', 2048;

GOsp_configure 'show advanced options', 0; RECONFIGURE;

5. Database Auto Growth Parameter

Database auto growth is set to expand only 1MB when full, which is not recommended, standard 10%

growth, must be made when the DB is full. This will make less overhead on SQL server, else server will

be busy most of times in expanding the database growth by 1MB each time when it is full, since 1MB is

very less expanding the database size will be on frequent basis on the server.

Store Build team will have to execute this script on newly built server to enable this option. Similarly SAP

team will have to use this same script and run it on SAP instances of server to make the autogrowth of

database to 10%. Use below attached script to enable this option on all databases at once.

NOTE: Follow the same steps mentioned in Step 3 to execute the above SQL script.

If any errors or failures while executing above script, Please contact [email protected]

Conclusion:

Implementing above mentioned steps will ensure that Store servers are stabilized and all prerequisites

are completed before the store is live.
