This post covers overview of Repository Creation Utility(RCU) which is first thing you need to do, if you are planning to implement/install Oracle Fusion Middleware 11g R1 (11.1.1.0).

Metadata Repository - contains metadata for Fusion Middleware Components (SOA, Webcenter, Identity Management) . There are various types of Repository - Metadata Services (MDS), Audit Services (IAU), Oracle Internet Directory (OID), Single Sign-On (SSO), SOA Infrastructure (SOAINFRA), Business Activity Monitoring (BAM) , User Messaging (ORASDPM) , Oracle WebCenter (WEBCENTER) , WebCenter Portlets (PORTLETS) , Oracle Content Server (OCSERVER) , Portal (PORTAL), Discoverer (DISCOVERER), Oracle Identity Federation (OIF) , Discussions (DISCUSSIONS) and Wiki and Blog (WIKI)

Repository could be Database-based or File-based, most component (Webcenter, SOA, OID…) requires Database-based Repository.
.

How to create Database-based repository ?
RCU - Repository Creation Utility is tool to create schema and load repository in existing database for Fusion Middleware components.

Download RCU from here

Key points for Repository Creation Utility (RCU) in FMW

1. RCU can be run in two mode - GUI (Graphical User Interface) & CLI (Command Line Interface)

2. For Fusion Middleware 11g R1 (11.1.1.X) , RCU can only load schema in Oracle Database (version 10.2.0.4 and higher or 11.1.0.7 and higher)

3. You can run RCU locally (same machine where Database is running) or Remotely (Database is on remote machine)

4. By default RCU creates default schema and load repository in default tablespaces. RCU provides flexibility to change schema or tablespace name. (Only exception to this is Oracle Internet Directory (OID) schema)

5. You could load multiple repository (like Portal, webcenter, SOAINFRA) in single database. You could also load different version of same repository (like dev_soainfra, test_soainfra for DEV & Test instance resp.) in same database. (This is interesting feature for using single database for multiple Fusion Middleware Instances)

6. You can start RCU (Repository Creation Utility) from $RCU_SOFTWARE/bin/ rcu (for Unix) or rcu.bat (for Windows) ; This will start RCU in GUI mode. For CLI mode use “rcu [-silent | -interactive] {<command> <options>}”

7. RCU log file is written to the RCU_SOFTWARE_DIR/ rcu/ log/ logdir.<date_timestamp>/ rcu.log

What to do after creating Fusion Middleware Database-based Repository ?
Before you can use Repository for fusion middleware component (soa, webcenter), you need to register Repository with Oracle WebLogic Server domain . (How to register Database-based with WebLogic domain ? coming soon…)
