I have a PROCEDURE sp_backupSSAS - it backups SSAS databases. it works fine.
I had previous problems with it, but they were sorted out here: routine to backup ssas databases fails with: The XML for Analysis request timed out before it was completed
generally I try to have SSAS on a server of its own - let's say server_SSAS
therefore I use a different server - let's say SERVER_SQL to backup the SSAS databases in the server_SSAS.
for me to run my procedure sp_backupSSAS that lives on server_SQL I first create a table type:
CREATE TYPE SSAS_DBs_to_Backup AS TABLE
( DBName sysname not null
,LocationName varchar(1008)
);
GO
This table type is used when I call the procedure. It tells me which database(s) to backup and the location where to put them (in the SERVER_SSAS)
From inside a job on SERVER_SQL:
DECLARE @DBS AS SSAS_DBs_to_Backup
INSERT INTO @DBS (DBName, LocationName) VALUES ('MY Company BI LIVE','H:\SQLBackups\')
EXEC sp_backupSSAS @DBS
This creates a backup on my server_SSAS which is called SQLBILON1:
That is all working fine, however, I would like to pass the name of the server_SSAS which in this case was SQLBILON1 as a parameter, and NOT have it hard-coded inside the procedure.
how can I achieve this?
the full code of the procedure is here:
--SELECT @@SERVERNAME
PRINT 'THE SERVER IS ' + @@SERVERNAME
--select db_name()
PRINT 'THE DATABASE IS ' + db_NAME()
PRINT ''
USE MASTER
GO

Script : PROCEDURE sp_backupSSAS
Author : Marcelo Miorelli
Date : 03-NOV-2014
Desc :
Backup the SSAS databases that are on table @DBS
needs the LINKED server to SSAS - in this case [SQLBILON1]
On the first version I left that static.

Usage :
DECLARE @DBS AS SSAS_DBs_to_BAckup
--INSERT INTO @DBS (DBName, LocationName) VALUES ('Boden BI LIVE','H:\SQLBackups\SQLBILON1\')
INSERT INTO @DBS (DBName, LocationName) VALUES ('Pyramid Demo 2013','\\SQLREPLON1\SQLBackups\SQLBILON1\')
EXEC sp_backupSSAS @DBS
