ARC1270 One or more UDF/UDM recompiles failed.
When restoring a User Defined Function (UDF) or a User Defined Method (UDM) from the SYSUDTLIB database, ARC may send a "recompile" request for that UDF or UDM to the DBS. If one or more "recompiles" fail, this message is displayed and ARC is aborted. This message only applies to UDFs/UDMs in the SYSUDTLIB database.
This is a fatal error.
In their current state, the UDFs/UDMs that reported error successfully compiled before you attempt to restore the rest of your system.
