This error is caused by multiple records in the compver table that have the same name, version, cvtype, and subsystem.

Informix Synergy Server environment.

Running backups and seeing the errors noted above.

1. Log in to the server as user ccm_root and set the environment variables.
   
   (bourne shell example):
   
   CCM_HOME=<install area path>; export CCM_HOME
      INFORMIXDIR=$CCM_HOME/informix; export INFORMIXDIR
      ONCONFIG=<SERVERNAME>; export ONCONFIG
      INFORMIXSERVER=<SERVERNAME>; export INFORMIXSERVER
      PATH=$CCM_HOME/bin:$INFORMIXDIR/bin:$PATH; export PATH
   
   Note: replace the values between the angled brackets < >, omitting these brackets.
   
   
   
2. Run the command:
   
   echo "unload to 'xxxxdb.compver' select
   id,name,version,cvtype,subsystem from compver" | dbaccess xxxxdb-
   
   This creates the file xxxxdb.compver. This file has 5 fields delimited by "|". The goal is to find the two rows whose last four fields are identical. (The first field is a unique row identifier).
   
3. Delete all but one of each duplicate. To delete an object from the database using SQL (Informix), set the above environment variables as user ccm_root and use these commands:
   
   echo 'DELETE FROM compver where id=NNNNN;
   DELETE FROM attrib WHERE is_attr_of=NNNNN;
   DELETE FROM bind WHERE has_child=NNNNN;
   DELETE FROM relate WHERE from_cv=NNNNN OR to_cv=NNNNN;' | dbaccess xxxxdb -
