Hello,
There is a guide to let SIM use a moved database, this can be used first stop de SIM service on the old SIM server.
Now go to the new SIM server and edit the following files to reflect the settings for the database the old SIM server uses.
Be aware you need to change the database, instance and port info in the files below:
1) go to C:\program files\HP\Systems Insight\Manager\config
2) edit database.admin
3) change hp.Database.hostName=
4) change hp.Database.instance=
5) edit database.props
6) change hp.Database.hostName=
7) change hp.Database.instance=
8) Edit *-ds.xml with new hostname and instance (in\jboss\server\hpsim\deploy)
-and-
there may be another file with a name like "tmpXXXXXpmp-ds.xml" in the folder \jboss\server\hpsim\tmp\deploy\ that you also should update.
10) START the HP SIM Service
11) wait for port 50000 to open
12) test.
