Sequence Tasks : Support for 64-bit sequences

Support for 64-bit sequences

Large sequences (those with 64-bit values) are enabled by default in newly created databases. Once a database is enabled for 64-bit sequence support, you cannot revert that database to 32-bit sequences. If you try to load a sequence value that is too large for an integer value, you are notified of the overflow error and the load process aborts.
When you look at a sequence's properties, you can now see the current value of a sequence if it has been committed.
If large sequences are not enabled, a Large sequence support not enabled message appears when you look at the Database or Sequence properties in the Data Dictionary.
To enable large sequences on a migrated database, use PROUTIL ENABLESEQ64 (see OpenEdge Data Management: Database Administration for more information).
