Microsoft Dynamic CRM SQL Server timeout expired


Most of us may have come across SQL timeout expired error while doing some operation in Microsoft Dynamic CRM.


















Resolution

The solution which I am proposing is only applicable to On-Premise and ADFS type of Dynamic CRM installations.

We need to increase the timeout in Registry configuration of windows where dynamic CRM is installed. 


The path to add registry sub key:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ MSCRM


There are two DWORD that need to be created.


DWORD 
Value (in Decimal)
OLEDBTimeout
86400
ExtendedTimeout
2147483647


Please Note

OLEDBTimeout
  • The recommended value of this is between 30 and 300. 
  • The value of 86400 is equivalent to 24 hours.


ExtendedTimeout
  • Value, can be larger than 1,000,000.
  • However, do not type a value that is larger than 2,147,483,647. This is hexadecimal 0x7FFFFFFF.


This should only be done temporarily or as a troubleshooting step.
Leaving this setting too high can result in performance issues.

After adding the DWORD it should look something like this.















MSDN provide a detail understanding of SQL time-out.

There are other Timeouts in Microsoft Dynamic CRM.

I hope this will help us avoiding Time out error in SQL.

Thanks.
