FIX: Arithmetic overflow exception after you run a BAM activity for a long time in Microsoft BizTalk Server 2006 R2: "Arithmetic overflow error converting expression to data type int"

In Microsoft BizTalk Server 2006 R2, after you run a Business Activity Monitoring (BAM) activity for a long time, you receive an arithmetic overflow exception that resembles the following:

This problem usually occurs when you have not implemented regular maintenance on completed activity instances in a BAM Primary Import database.

Note Regular maintenance includes activities such as archiving or deleting.

This problem occurs because the recordID variant is defined as the INT data type in several BAM-related stored procedures. However, in BAM Tables, the recordID field is defined as the BigINT data type. Therefore, when the number of records exceeds the upper limit of the INT data type, you receive an arithmetic overflow exception.

Note The upper limit of the INT data type is 2,147,483,647.
