SQL Database Properties Not Discovered

  • Artykuł

I ran into an issue recently where some SQL Databases were not showing any properties in OpsMgr, other than the database name:

To get these properties, the database discovery script runs the “sp_helpdb” stored procedure against the database.  To test this, open SQL Server Managment Studio, connect to the SQL Instance in question, open a new query window and run “sp_helpdb <database name>”":

NOTE: You should run this under the same account that is used for the “SQL Server Discovery Account” RunAs Profile….if you haven’t defined an account for this profile, then use the Action Account.

If this doesn’t return any results (as shown below), then the problem is likely due to permissions.  From the SQL MP guide, the requirements for DB discovery are:

· EXEC permissions for (sp_helpdb)

· Select from sys.databases table in the master database

Also, before running sp_helpdb, the discovery script will query to get a list of databases.  In SQL 2005/2008, the query is:

SELECT name, state_desc FROM sys.databases WHERE source_database_id IS NULL

In SQL 2000, the query is:

SELECT name FROM sysdatabases

 

The difference is that in SQL 2005/2008, we have the “WHERE source_database_id IS NULL“ clause, which will eliminate snapshot databases…..so if the SQL instance has any snapshot databases, they will not be discovered.  We also select the “state” column from sys.databases in SQL 2005/2008 DB discovery, and if the state is not “ONLINE”, then the discovery ends there….so this would be another reason why the database properties do not show up in OpsMgr.

Attached to this blog are debug version of the database discovery script:

DiscoverSQL2005DB_debug.txt – Use this for SQL 2005/2008

DiscoverSQL2000DB_debug.txt – Use this for SQL 2000

To run the script:

  1. Rename to .vbs
  2. Run the following command:

cscript DiscoverSQL2005DB_debug.vbs <fqdn> <Server\instance> "exclude:"

Replace the bold items with:

<fqdn> = Full Qualified Domain Name of the SQL Server (server.domain.com)

<Server\instance> = SQL Server instance that we want to discover DBs on.  If it is the default instance, it will just be the server name (SERVER), otherwise it will be SERVER\INSTANCE

Sample output from my server:

Server name is jimmyhsql1.jimmyhdom.com

SQL instance is OpsDB

Command line is cscript discoversql2005db_debug.vbs jimmyhsql1.jimmyhdom.com jimmyhsql1\opsdb "exclude:"

Output (I only copied the output for the first couple DBs):
