  37. 37. Handling Issues" u  Not all migrations are error free •  Migration log will contain all errors" u  Some common issues: •  Column delimiter chosen is in column data" –  Causes ‘Extra data found’ error! –  Resolve by using different delimiter! u  Oracle built-in package does not exist •  DBMS_AQ – we use solutions like ActiveMQ, MQSeries or Tibco" –  Or own code. Enqueue and dequeue procedures are fairly easy to code! –  xDB Replication Server can also be used since based on pub/sub architecture! –  DBMS_RANDOM – use random function instead! –  DBMS_LOCK.sleep – use pg_sleep function instead! u  Oracle feature not supported •  MERGE command not supported" –  Can be rewritten to use INSERT and UPDATE with checks! •  Index Organized Tables" –  Cluster a table using CLUSTER! command for same read performance gain!© 2011 EnterpriseDB. All rights reserved. 37
  38. 38. Handling Issues (continued)" u  Database Links •  Migrated over by tool but password is invalid" –  This is because Oracle hides the password! –  Resolve by dropping and recreating! –  Or by specifying a password to use when running the MTK! –  runMTK -allDBLinks LINK_NAME1=abc,LINK_NAME2=xyz HR u  Data Movement – performance •  Migration toolkit connects via jdbc" •  Large datasets are slow to move" •  Use database link functionality instead" –  Dblink_ora_copy – EnterpriseDB method to copy data from Oracle over OCI! –  Much faster! •  OR extract data from Oracle to csv files, the load using edbldr" " "© 2011 EnterpriseDB. All rights reserved.
  39. 39. Tuning Recommendations" u  Use DynaTune •  Dynamically adjusts database configuration based on available resources" •  Set via edb_dynatune parameter" –  Values 0 – 100 corresponding to % of machines to use! u  Remember to analyze database •  Use Analyze command" u  Oracle Hints supported •  No need to remove from embedded SQL"© 2011 EnterpriseDB.
