Creating a Partitioned View in the Archiving Database

  • Article

When you run the BAM data maintenance package (BAM_DM_<activity name>) BAM copies each partition in the BAM Primary Import database to a separate table in the BAM Archive database. If you detach the archive database and reattach it for querying, it will be difficult to locate the data for your query.

You can create partitioned views in the BAM Archive database to facilitate locating the data. BAM supports up to 253 partitions. For each activity, BAM generates one BAM data maintenance DTS package, which copies the activity data to the BAM Archive database and then removes it from the BAM Primary Import database. If the archive database fails after the data is copied but before the next backup, data is lost.

The solution to prevent lost data is to have a single archiving package, which first copies the old data from all activities, then backs up the BAM Archive database, and finally drops the partitions that were copied from the BAM Primary Import database.

Prerequisites

You must be logged on as a member of the BizTalk Server Administrators group to perform this procedure.

Create a partitioned view in the BAM Archive database (SQL Server 2008 SP1 or SQL Server 2008 R2)

  1. Open SQL Server Management Studio.

  2. Select the BAM Archive database, and then click New Query.

  3. On the Query menu, point to Results To and then click Results to Text.

  4. Copy the following SQL script into the query pane. Replace <activity name> with your activity name, and replace <view type> with either Instances for instance view or Relationships for relationship view.

    set nocount on

declare @activityName as nvarchar(128)
declare @viewType as nvarchar(50)
set @activityName = N'<activity name>'-- Substitute your activity name here
set @viewType = N'<view type>'-- Substitute the view type here, either "Instances" or "Relationships"

declare @tableName nvarchar(128)
declare @viewName nvarchar(128)
declare @isFirstTable bit
declare @scriptLine nvarchar(300)

set @viewName = N'bam_' + @activityName + '_' + @viewType + 'View'
select N'SELECT Name FROM sysobjects where name = N''' + @viewName + ''' and type = ''V'''
 + char(13) + char(10) + 'IF @@ROWCOUNT > 0 DROP VIEW ' + @viewName
 + char(13) + char(10) + 'GO'

select 'CREATE VIEW ' +  @viewName + ' AS ' + char(13) + char(10)

declare instance_cursor cursor local for
select name from sysobjects
where name like N'bam_' + @activityName + '_' + @viewType + '_%' and type = 'U'

SET @isFirstTable = 1
OPEN instance_cursor
FETCH NEXT FROM instance_cursor INTO @tableName

WHILE @@fetch_status = 0
BEGIN

if @isFirstTable = 1
BEGIN
SET @scriptLine = N'SELECT * FROM [' + @tableName + ']'
SET @isFirstTable = 0
END
ELSE
SET @scriptLine = N'UNION ALL SELECT * FROM [' + @tableName + ']'

SELECT @scriptLine

FETCH NEXT FROM instance_cursor INTO @tableName
END
CLOSE instance_cursor
DEALLOCATE instance_cursor

select 'GO'
set nocount off

  5. Execute the query.
