7506 The library for UDF/XSP/UDM %DBID.%TVMID could not be found
All UDFs/XSPs/UDMs are linked in a dynamic linked library or in a package which must exist on all nodes on the database system. The library for this UDF/XSP/UDM could not be found on at least one node.
If the UDF/XSP/UDM is in a package make sure the package has not been deleted or propagated to all nodes. If the UDF/XSP/UDM is in a library then it has been deleted on some node. To generate a new library compile the UDF/XSP/UDM via the ALTER FUNCTION/PROCEDURE statement using the COMPILE option. This create a new UDF/XSP/UDM library. If the UDF/XSP/UDM is called or executed in protected mode, make sure on each node the library and all the dependency libraries exist and were given the correct file permission. Check the system log for error 7820 for more specific information.
