sys.commit()
sys.commit()
Purpose:
-
sys.commit() commits a 4C transaction.
Usage:
-
-
ret = sys.commit(<tname>);
Arguments:
-
alpha <tname> - A program specific name for the transaction.
This name must be the same used that started the transaction.
Returns:
-
0 - Transaction committed
-
-1 - Either the transaction specified by <tname> does not exist or
the transaction was aborted. Check sys.errno for ABORT_ERR.
Transactions may be aborted due to deadlock situations.
Where Used:
-
sys.commit() can be called from anywhere,
but it can only commit a transaction started within
the same 4c program.
When possible you should try to use sys.commit()
within the same PCL that called sys.begin().
Example:
-
See
sys.begin()
for example code.
Description:
-
sys.commit() commits the transaction specified by <tname>
as well as any nested transactions.
Only explicit transactions started by the application can
be committed by the application and the transaction must have
been started by the same 4C program that calls sys.commit().
You cannot start transaction, "T1", in programA, push ProgramB
and commit the transaction, "T1", in progranB.
