You are absolutely right. I have spent a few miserable days messing about with this . You can't install HP SIM 7.2 over 7.3 so I had to uninstall HP SIM 7.3. I then installed HP SIM 7.2 but it did n,t pick up the original database. It installed a fresh database. No use to me as I have a lot of servers, configured tasks etc. I tried pointing HP SIM 7.2 towards the original database by editing files by following the following instructions from a HP Guide on changing databases -
Manually re-registering a new database by altering the HPSIM configuration files
1. Create a backup of the database.props, database.admin, databaseadminupd.tpl and databaseupdate.tpl files located in <installation directory>\HP\Systems Insight Manager\config.
2. You must modify some settings for the new database changes in Systems Insight Manager in each of the following property files: database.props, database.admin, databaseadminupd.tpl and databaseupdate.tpl files. Update these files with the following information, and then save the files.
a. Change the value after hp.Database.hostName=source-server-name to target-server-name.
b. Change the value after hp.Database.instancename=source-server-name \\source-instance to target-server-name\\target_database_instance.
c. If the database user account is a local user account, change the value after hp.Database.username=source-server-name to target-server-name\\username.
d. If moving to a different SQL server, it may use a different port. If this is the case, update the value after hp.Database.portNumber= to the new port number.
3. Create a backup of the hpsim-ds.xml file located in the <installation directory>\HP\Systems Insight Manager\jboss\server\hpsim\deploy directory. Do not place the backup file in this directory.
4. Modify the hpsim-ds.xml file located in the <installation directory>\HP\Systems Insight Manager\jboss\server\hpsim\deploy directory.
a. Locate the line with the <connection-url> XML tag; it will look similar the following: <connection-url>jdbc:jtds:sqlserver://dbServerName:1433/Insight_v50_0_###
b. Change the dbServerName text from the old SQL Server host name to match the new SQL Server host name. ; loginTimeout=20;domain=dbServerName;instance=source-instance</connection-url>
c. If moving to a different SQL server it may use a different port. If this is the case update the port number that follows the first dbServerName (for example, dbServerName:1433).
d. If the target database has a different database instance, update the instance name after the instance= parameter.
5. Start the Systems Insight Manager service.
This allowed my HP SIM 7.2 to see the original database. I can see my collections etc but I cannot receive any traps.
Wbem subscriptions are gone. Its just a total pain.
I'll be logging a call with HP and we will see how I get on.
