SWITCH bind option
The SWITCH option causes the previous copy or original copy of a package to become the current copy of the package.
| SWITCH | ( PREVIOUS )( ORIGINAL ) | On: REBIND PACKAGE and REBIND TRIGGER PACKAGE |
This option allows you to revert to an older copy of a package in the event of a performance regression. You cannot specify SWITCH with any other rebind options. If the package that you specify does not have the previous or original copy to switch to, DB2® issues an error message, and continues processing the rest of the list. Use this option with the pattern-matching character (*) in the syntax.
- (PREVIOUS)
Switches between the current and previous
copies of a package or a plan. The current copy takes the place of the previous copy, and the
previous copy takes the place of the current copy.
- (ORIGINAL)
- Moves the current copy to take the place of the previous copy. Any previous copy that exists is purged. The original copy is cloned to take the place of the current copy.
