sdsInitiateTakeover
sdsInitiateTakeover(takeoverMode: Integer;
nextPrimaryServer: String);
The sdsInitiateTakeover method of the JadeDatabaseAdmin class initiates a negotiated take-over of the primary database by the secondary server specified in the nextPrimaryServer parameter.
The takeoverMode parameter specifies how the take-over operation will deal with potential conflicts between executing reader processes and database state that is being isolated, which will become visible when the secondary server assumes the role of a primary database. The values for the take-over mode are represented by one of the
| Global Constant | Integer Value | Take-over is … |
|---|---|---|
| SDS_TakeoverConditional | 1 | Conditional on there being no conflicts |
| SDS_TakeoverForced | 2 | Forced if conflicts exist |
A runtime exception is raised if this method is called for a Relational Population Service (RPS) node.
This method should be invoked only within an SDS primary system. Invoking this method from within a secondary system raises an exception.
