Is there an equivalent to sp_getapplock, sp_releaseapplock in oracle

I need the ability to use custom locks at a session level (outside the scope of a transaction) in oracle.

开发者_Python百科In MSSQL I am using sp_getapplock, sp_releaseapplock.

How can I achieve the same functionality in Oracle?

DBMS_LOCK Package

This will do what you want:

dbms_lock.allocate_unique('control_lock', v_lockhandle);
v_result := dbms_lock.request(v_lockhandle, dbms_lock.ss_mode);
...
v_result := dbms_lock.release(v_lockhandle);
