Compatibility Issues Between the TimesTen and Oracle Databases

There are some compatibility issues between the TimesTen and Oracle databases.

For example:

  • TimesTen and Oracle database metadata are stored differently.

  • TimesTen and Oracle databases have different transaction isolation models.

  • TimesTen and Oracle databases have different connection and statement properties.

  • Sequences are not cached and synchronized between the TimesTen database and the corresponding Oracle database.

  • Side effects of Oracle database triggers and stored procedures are not reflected in the TimesTen database until after an automatic or manual refresh operation.
