Example Let's look at an example that shows how to issue a commit in Oracle using the COMMIT statement. For example: COMMIT; This COMMIT example would perform the same as the following: COMMIT WORK WRITE WAIT IMMEDIATE; In this example, the WORK keyword is implied and the omission of the...
In Oracle 10g Release 2 theCOMMITcommand has been enhanced with theWRITEclause to give a degree of control over the way redo information is written to the redo logs during the commit operation. This can improve performance, but it should only be used for processes that meet the following crit...

Note that this method takes calls to invocationCallback(com.oracle.bmc.http.client.RequestInterceptor) into account, while the method buildWithoutInvocationCallback() does not. This is the preferred method to build an instance. Specified by: build in interface BmcRequest.Builder<CommitMu...
Example : delete from emp; rollback; /* undo the changes */ SAVEPOINT Specify a point in a transaction to which later you can roll back. Example insert into emp (empno,ename,sal) values (109,’Sami’,3000); savepoint a; insert into dept values (10,’Sales’,’Hyd’); ...
(LGWR) writes redo for the commit, along with the accumulated redo of all changes in the transaction, to disk. By default, Oracle Database writes the redo to disk before the call returns to the client. This action introduces a latency in the commit because the application must wait for ...
