Installing a New Node to an OID Cluster Fails With: Configuration failed for IAS oracle.ias.configtool.config.ConfigException: IAS Instance exists already. (Doc ID 743227.1)

Last updated on AUGUST 08, 2017

Applies to:

Oracle Internet Directory - Version: to - Release: 10gR3 to 10gR3
Information in this document applies to any platform.


A OID consisting of two or more nodes was installed.
The cluster was then upgraded to OID

Because is a patchset, not a full release, it is not possible to add a new node to the cluster. But attempting to add an additional node to the cluster fails because the Metadata Repository has been upgraded to, and thus the installer rejects it as being at an
inappropriate version.

Steps to Reproduce:

  1. Install a DB (e.g., 10.2)
  2. Run MRCA
  3. Install IDM against that MRDB
  4. Upgrade MRDB & IDM tier to
  5. Install a new IDM against that upgraded MRDB

Note: The two midtiers must reside on different physical machines to see the error
