Microsoft Dynamics CRM 4.0 updates and hotfixes

Installation information

Install this cumulative update rollup on computers that are running the Microsoft Dynamics CRM 4.0 Router components.

To maximize the performance of this cumulative update rollup, you must add additional SQL Server indexes to the <OrganizationName>_MSCRM database. <OrganizationName> is a placeholder for the name of the Microsoft Dynamics CRM organization. You can do this before or after you apply this hotfix.

Before you add the additional SQL Server indexes, verify that the additional SQL Server indexes do not already exist in the MSCRM database. To do this, run the following commands against the MSCRM database:

sp_helpindex ActivityPointerBase
sp_helpindex ActivityPartyBase
sp_helpindex EmailBase

If the additional SQL Server indexes exist, these commands will result in output that resembles the following:

index_name index_description index_keys
cndx_ActivityPointer clustered, unique located on PRIMARY ActivityId, StateCode, ActivityTypeCode
ndx_ActivityPointerCover1 nonclustered located on PRIMARY ScheduledEnd, RegardingObjectTypeCode

Verify that none of the additional SQL Server indexes have columns that are the same as the ones in the indexes below. If a duplicate index is created, it will make the Microsoft Dynamics CRM SQL performance slower rather than faster.

To create the additional SQL Server indexes, run the following SQL statement in SQL Server Management Studio. Change the USE <OrganizationName>_MSCRM statement to the actual organization and database name.


USE <OrganizationName>_MSCRM
GO

CREATE NONCLUSTERED INDEX [CRM_ActivityPartyBase_EmailRouter1] ON [dbo].[ActivityPartyBase] 
(
[ActivityId] ASC,
[ParticipationTypeMask] ASC,
[PartyId] ASC
)

WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) 
ON [PRIMARY]
GO

CREATE NONCLUSTERED INDEX [CRM_ActivityPartyBase_EmailRouter2] ON [dbo].[ActivityPartyBase]
