OIM - SOA : Value too large for column "WFMESSAGEATTRIBUTE"."STRINGVALUE"

Issue Description:

For every request in OIM, OIM User Interface allows justification of 4000 characters but if you provide justification of 4000 characters, you will see error in the SOA Logs:

ORA-12899: value too large for column "_SOAINFRA"."WFMESSAGEATTRIBUTE"."STRINGVALUE" (actual: 4000, maximum: 2000) 

which means SOA supports justification of maximum of 2000 characters.

Workaround:

Put a solution in OIM UI (can be done in many ways) to restrict users from entering justification of more than 2000 characters.
