odbc master connection

I'm using HP SIM 5.1 on W2K3 and msql2003. At the moment HP SIM has configured two odbc connections, one for the HP SIM database and one the MSQL master database. Due to security constraints in the environment I'm setting it up, a connection to the master db is not allowed.

What is the purpose of having a connection to the master database and how will the functionality of HP SIM be influenced/impaired if I remove this connection?

Re: odbc master connection

As far as I'm aware HPSIM uses the database.props file for details of its database connection and these only reference the HPSIM database itself.

Where are you seeing these ODBC connections?

Re: odbc master connection

The odbc connection is created during installation of HP SIM. It's a windows odbc connection (control panel -> Data Sources (odbc)).

Re: odbc master connection

Hello,
HP Systems Insight Manager (HP SIM) uses a Microsoft SQL Server 2000 Service Pack 3, MSDE (Windows Install), or PostgreSQL SQL 7.4.x (HP-UX or Linux install) database to store collected event and system data.
The database can be on the same system as the management application or on a different system that has network access to the database server. However, configuration of HP SIM database tables cannot be performed on a remote system. HP SIM uses the Java DataBase Connectivity (JDBC) and the Open DataBase
Connectivity (ODBC) on Windows systems to communicate with the database.
During installation, the necessary database systems and transaction log systems are created before creating and populating the database.
***************************************
Only the HP SIM application should add or delete from these tables. Any other modifications to these tables cause cache coherency problems for the application.
***************************************
The database contains:
â ¢ Events
â ¢ Discovered systems
â ¢ System status
â ¢ User preferences
â ¢ Detailed system information
â ¢ Language text (English only)

Reports can be created in Microsoft Access, Excel, Crystal Reports, or any standard reporting tool that can access the database. The database schema is published to make creating the reports easier.

Predefined views
Several predefined views are shipped with HP SIM. These views can be used to search the database for different information such as data collection information, event data and license data.
1)Notices_view. This view can be used to list events in the system along with their descriptions. It does not contain the specifics of an event, but it can be useful for some simple reports. It returns the system name,event severity, cleared status, received time, cleared time and event description.
2)View_deviceAssociations. This view is used in building searches, mainly used internally.
3)licenseCounts. This view is used to show license count data in the license report.
4)deviceTypesEnum. This view links the devices_table productType field with an (English) string representing the system type.
5)deviceSubTypesEnum. This view links the nodeSubTypesEnum table enumOrd field with an (English) string representing the system subtype.

The database and views are not deleted when you uninstall HP SIM.

Connection to the database will resultin abnormal Functionality of HP SIM.

Cheers !

CORRECTION : "Connection LOSS to the database will result in abnormal Functionality of HP SIM."

Yo !

Re: odbc master connection

This really does not make sense. The whole idea of odbc is to make the connection to a database transparent, local or remote should have no difference. But that's beside the point, what I'm trying to figure out is what is the reason for the odbc connection to the mssql master database.

Problem solved.

When HP SIM is installed, the two odbc connections are created, but it is not used. Maybe for the setup scenario, but after that it can be removed.

The full impact of this is unsure.

Odbc connection is not used after the setup.
