IV56194: SITUATION OVERRIDE FAILS FOR SPECIFIC COLUMN NAME.

IBM Tivoli Monitoring 6.3.0 Fix Pack 4 (6.3.0-TIV-ITM-FP0004)

APAR status

• Closed as program error.

Error description

• For the following override condition:
  
  
   <situation name="alltest_greg" active="Y"
  originnode="RZ:warehous2-phoenix-HEMPLAP:RDB" priority="100"
  lastupdate="1140303165550000"
  objname="alltest_greg___65E62E793C3C41F4"
  >
    <default>
     <threshold column="PCIFMAX" value="9800" operator="LT"
  ></threshold>
    </default>
    <key column="TNAME" value="TIVOLIORTS">
     <threshold column="PCIFMAX" value="10000" operator="LT"
  ></threshold>
    </key>
   </situation>
  
  the TIVOLIORTS TNAME is not being honored as an override.  The
  TIVOLIORTS tablespace is only being checked for < 98 and not
  100.
  
  RECREATE INSTRUCTIONS:
  See above xml for the override conditon that is failing.
  Customer has a more complex override that fails also.
  
  The problem is tied to an override for an empty table name along
  with a specific table name.  If the empty table name expression
  is removed then any specific tablename override works.
  

Local fix

• Do not use an empty table name in the override, always use a
  specific tablename for overrides.  But this may not do what the
  customer wants.
  

Problem summary

• Situation override fails for specific column name.  The problem
  is when an override for a default column along with a specific
  key column name is defined.  If the key column name expression
  is removed or a new key column name expression is added, the new
   or changed key column is not processed for the override.
  

Problem conclusion

• Corrected the XML creation in the monitoring server to return
  the <default> XML keyword last.  Also, fixed a memory exception
  in the agent monitoring agent code for the copy constructor for
  the key and predicate of the expression override.  The copy
  constructor failed to initialize a variable to NULL.
  
  The fix for this APAR is contained in the following maintenance
  packages:
  
    | fix pack | 6.3.0-TIV-ITM-FP0004
  

Temporary fix

• Do not use an empty column name in the override, always use a
  specific column name for overrides.
