oracle to postgresql migration tool

어차피 function code는 검토해야하는 할테니, 사용할 만할 듯합니다.

For migrating with ora2pg, there are few concerns as follows.

Schema list

  • For case-sensitivity, some schemas may need to be created with double-quotes. Need to check that both of the lower and upper case schemas are in use.
  • There are locked schemas in Oracle database. Need to check if they need to be migrated.
    • Synonym : not compatible
    • Trigger
  • AFTER LOGON ON TRIGGER – not compatible
  • Need to verify the codes
    • Package
  • The packages will be migrated to the functions on separated schema named oracle package name. So the duplicated packages may need to be renamed.
  • Need to verify the codes
    • Column name
  • Column name with reserved keyword need to be renamed.
  • Ora2pg would generate incoherent scripts when it comes to case-sensitivity. We may need to verify the scripts regarding case-sensitivity.
    • Date/Time Functions
  • Oracle systimestamp is not compatible with postgresql. We may need to verify its functionality and switch to postgresql function. Share this:
