SQL Server Performance issue - With DB Compatibility upgrade from 120 to 150

Worked Solution:

We turned on the Legacy Cardinality Estimation on the database properties. 

If anyone has other solutions please comment.

SQL Server 2022 Services Failed To Come Online.

Error: Script level upgrade for database ‘master’ failed because upgrade step msdb110_upgrade.sql encountered error 926, state 1, severity 25

The above error will be present in the Error log and the solution will be to start the SQL Server either from /T902 or add this in strtup parameter to permently resolve this issue. 

This will bypass the upgrade script and starts the SQL Server.

Failed to initialize sqlcmd library with error number -2147467259.

This error has too many options to fix, one of them is below resolution - 

In our case we were using a dynamic query which will send some results over the email with help of dynamic execution. when the query was executed using sp_send_mail it used to fail.

Failed to initialize sqlcmd library with error number -2147467259.

After couple of hours identified that query results using linked server was causing the issue. 

An error occurred during Service Master Key decryption There is no remote user ' ' mapped to local user '(null)' from the remote server ' '. (Microsoft SQL Server, Error: 33094)

To fix this we need to run 

        ALTER SERVICE MASTER KEY FORCE REGENERATE

Once the above command executed linked server started working properly. The dynamic query started to work smoothly, which inturn resolved the issue. 

SSRS not starting - unable to connect to the report server

 After the windows upgrade few cases WMI RS integration will be corrupted, during that time we get the error "Unable to connect to the Report Server "

Solution : 

Based on the SQL Server Version the MOF file will be located in different locations, in our case it was on D drive.

1. Open CMD prompt with elevated privileges

2. Run below command 

mofcomp "D:\SQL Server Files\MSRS13.MSSQLSERVER\Reporting Services\ReportServer\bin\\reportingservices.mof"
