PP CHCKTIME=n	60	Specify time interval in seconds for connection and transaction monitoring of the UDS-D task n=60..900
PP DEADTIME=n	60	Time interval in seconds for resolution of cross-configuration deadlocks or deadlocks in connection with openUTM n=5..900
PP DISDB=n	1	Maximum number of remote databases that can be addressed per transaction; n=1..32
PP DISTABLE=[:catid:][$userid.]    filename	-	Define input file for creating the distribution table
PP DISTRIBUTION={NO |                   STANDBY |                   START}	NO	Control participation in UDS-D mode: NO: UDS-D mode is not possible STANDBY: UDS-D mode is ready and can be subsequently started with &START DISTRIBUTION START: UDS-D mode is started
PP PTCSYNCH=   ([{WAIT | ABORT | COMMIT}]    [,[{WAIT | ABORT | COMMIT}]])	(WAIT,WAIT)	Control handling of transactions in the PTC state; the first value applies to a warm start; the second applies during a running session if the state of the primary subtransaction cannot be determined
PP TRANSACTION={n | ([n][,m])}	(4,1)	n: Maximum number of simultaneously active transactions and user tasks n = 1..225; m: Maximum number of secondary subtransactions that can be processed concurrently by this DBH m = 1..n and m <= n
