    Migrating Fusion Middleware IM (OID/SSO) to new Host
    Saturday, April 07, 2007
    Register for R12 upgrade

























    Identity Management is Infrastructure Component of Fusion Middleware Family. It mainly consist of OID (Oracle Internet Directory), SSO (Single Sign-On), DIP (Directory Integration and Provisioning), DAS (Delegated Administrative Services) and CA (Certifying Authority). It also consist of database (repository) to hold data related above mentioned components.


    In today's post I am going to cover overview or main steps of moving IM component (OID, SSO, DAS and DIP) to new Host/Machine.


    In What Scenarios one has to move IdM to new Machine/Host ?


    Few conditions in which one can consider moving Identity Management to new machine are
    1) Original Machine hold some other software/databases and load on that Server has increased considerably over initial deployment so you wish to move IdM to bigger machine.
    2) Migrating from one operating system to other (Corporate level decision to move from Solaris/HP machine to Linux System)
    3) You want to create DR site for Infrastructure Tier for disaster recovery (Don't stop LDAP replica in this scenarios)


    Assumptions made on this Migration


    1. This post does not cover moving Certifying Authority.
    2. Steps mentioned here are specific to version 10.1.2.0.2 which may change in future with new release (Though underlying steps might hold true for future version)
    3. You will use LDAP Based replica under High Availability Section while installing target instance (Though Database Advance replication will also work but I have not tested that)



    Broad Level Steps for Migration

    1. Install Infrastructure tier on New Machine
    (Select High Availability and Replication and then Replication, LDAP Based during Installation)




















































    2. Migrate SSO and DIP data from Source to Target IdM instance
    Use ssomig -import export tool for sso data
    Use dipassistant reassociate tool for DIP data


    3. Repoint point Middle tier to New IdM or OID/SSO machine.
    Use iAS Console for this. Click on Infrastructure Tab > Change
    Identity Management Section


    Where to find more documentation ?

      Atul,

      This is nice very useful site.

      Could you pl let me know the ways to migrate OID info from one host to another, but the target host already has the repository.

      Thanks
      Kumar
