Repository user accounts

Each component accesses the repository through a user account on the repository computer or the repository virtual machine.

Repository computer user accounts

When you install the repository server on a computer, IBM Installation Manager creates an informix user account on the computer if the informix user account does not exist. By default, the informix user account is created with the password opt1234X. The informix user account is used for repository manager and server administration (start the repository manager and repository server) and for repository access for most components

When you install the repository manager on a computer, Installation Manager creates a user account on the computer with a user name of your choice. Use this account for tasks other than administration and for repository access for the proxy. You can use any user name and password for this user account. By default, Installation Manager creates user account optim with the password opt1234X.

Virtual machine user accounts

There are three predefined user accounts on the repository virtual machine.
ID Default password Use the account for:
admin opt1234X Virtual machine administration (shutdown or restart)
informix opt1234X Repository manager and server administration (start the repository manager and repository server), repository access for most components
optim opt1234X Tasks other than administration, repository access for the proxy

Changing passwords

The informix user account is used by the repository manager, the designer, the manager, the service interface, and the server to access the repository databases. If you change this password, you must also change the password that is used by these other components to access the repository databases. The password must be changed in the following locations:
  • Repository manager: change the -Dcom.ibm.nex.informix.password property of the /opt/IBM/InfoSphere/Optim/repo/manager/eclipse.ini file.
  • Designer: right-click on the repository in Repository Explorer, click Open, and change the password.
  • Manager and service interface: change the password that the application server uses for the database pool or data source named OptimManagerIDS.
  • Server: change the password in the Connect to Database properties of the Optim™ directory (which can be set through the Configuration program).

If you change the password that the proxies use to access the repository databases, you must configure the proxies to use the new password. The password can be changed in the -Dcom.ibm.nex.informix.password property of the install_folder/proxy/eclipse.ini file, where install_folder is the base installation folder for InfoSphere® Optim components. The default base installation folder on Linux and UNIX is /opt/IBM/InfoSphere/Optim, and the default base installation folder on Microsoft Windows is C:\IBM\InfoSphere\Optim\.

If you must change the password in a configuration file, encrypt the password before you change the password in the file. Use the optimcmd -encrypt password or optimcmd -c password command to encrypt the password. The optimcmd tool is installed with the manager, the repository server, and IBM® InfoSphere Optim Repository, and is in the /tools/optimcmd folder for each component. For example, if you install the manager on a Windows computer, the default location of the optimcmd tool is C:\IBM\InfoSphere\Optim\shared\tools\optimcmd\optimcmd.bat.
