db2ACSPrepare - prepare to perform a snapshot backup operation.
When a snapshot backup is performed, the database manager
suspends the database. db2ACSPrepare() performs
all the steps to prepare to perform a snapshot backup operation up
to, but not including, the point where the database manager suspends
the database.
db2ACSEndQuery - end a query about snapshot backup objects
The database manager uses the DB2 Advanced
Copy Services (ACS) API functions db2ACSBeginQuery() and db2ACSGetNextObject() to
query about snapshot backup objects that are available to use for
restore operations. db2ACSEndQuery() terminates
that DB2 ACS query session.
