How do I change my Veritas SF RAC installation to use UDP instead of LLT?

Using UDP with Veritas Clusterware and Oracle RAC 10g seems to require an exception from Veritas so this may be something you should check with them. To make it easier for customers to convert their LLT environments to UPD, Oracle has created Patch 6846006 on 10.2.0.3 which contains the libraries that were overwritten by the Veritas installation (IE those mentioned above). Converting from specialized protocols to UDP requires a relink after the Oracle libraries have been restored. This needs a complete cluster shutdown and cannot be accomplished in a rolling fashion. NOTE: Oracle RAC 11g will not support LLT for interconnect.
