BSABeginTxn
Begin a transaction.
SYNOPSIS
#include <xbsa.h>
int BSABeginTxn(BSA_Handle bsaHandle)
DESCRIPTION
The BSABeginTxn() call indicates to the NetBackup XBSA interface the beginning of one or more actions that are executed as an atomic unit, that is, all of the actions will succeed or none will succeed. An action can be assumed to be either a single function call or a series of function calls that are made for a particular purpose.
For example, a BSACreateObject() call followed by a number of BSASendData() calls and terminated by a BSAEndData() call can be considered to be a single action.
In normal use, a BSABeginTxn() call is always coupled with a subsequent BSAEndTxn() call. If BSATerminate() is called during a transaction, the transaction is aborted.
If BSA_SERVICE_HOST has not been specified before calling BSABeginTxn(), the default NetBackup server is determined and the feature is checked for a valid license key. The feature_ID is the default DataStore feature_ID unless a specific NetBackup feature_ID has been specified using NBBSA_FEATURE_ID. If a valid license is not found, the transaction returns a NBBSA_RC_FEATURE_NOT_LICENSED error and not open the transaction.
Nested transactions are not supported.
