You can add or delete a key faster than in previous releases, because enhancements let you change table definitions in non-SQL applications more quickly. The ability to add and delete keys faster helps users meet 24x7 operational requirements. Adding and deleting keys faster substantially reduces outages due to time lost in adding another key to a table or removing a key from a table.
To use this feature, databases must be executing with the Directory (CXX) format indicator that is specified as FORMAT 2. The CXX format indicator is a new column that is printed in the database section of the CXX report. It indicates whether you want databases to remain compatible with r11 (FORMAT 1) or be fully compatible with Version 12 (FORMAT 2).
Note: For more information, see the Add and Delete Keys Faster topic in the CA Datacom/DB Database and System Administration Guide.
