When the degree of parallelism for user servers is changed, the specification of the parallel_count operand of the user service definition must also be changed.

The following table lists the definitions that must be reviewed when the degree of parallelism for user servers is changed and indicates under what conditions a review is required.

Table 7-4 Definitions that must be reviewed when the degree of parallelism for user servers is changed

Definition file name	Definition	Condition under which a review is required
betranrc jnl nam prc scd trn	max_socket_descriptors	The definition must be reviewed unconditionally.
cltsrv	cup_parallel_count	The definition must be reviewed when an RPC is received via a permanent connection from TP1/Client/P or TP1/Client/W.
	parallel_count	The definition must be reviewed when a transactional RPC is received from TP1/Client/P or TP1/Client/W.
dam	dam_cache_size	The definition must be reviewed when a DAM file is accessed.
	dam_cache_size_fix	The definition must be reviewed when a DAM file is accessed.
	dam_tran_process_count	The definition must be reviewed when a DAM file is accessed.
env	dynamic_shmpool_size	The definition must be reviewed in the following cases: When a DAM file, TP1/Message Queue, or an MCF queue file is accessed When the number of UAPs that send or receive messages in the MCF communication process increases
	static_shmpool_size	The definition must be reviewed unconditionally.
lck	lck_limit_fordam	The definition must be reviewed when a DAM file is accessed.
	lck_limit_formqa	The definition must be reviewed when a TP1/Message Queue file is accessed.
	lck_limit_fortam	The definition must be reviewed when a TAM file is accessed.
	lck_limit_foruser	The definition must be reviewed when the dc_lck_get function is used.
prc	prc_process_count	The definition must be reviewed unconditionally.
scd	scd_hold_recovery_count	The definition must be reviewed when it is necessary to inherit the shutdown state of the user servers whose degree of parallelism is changed.
	scdbufgrp	The definition must be reviewed when a schedule buffer group is used.
	scdmulti	The definition must be reviewed when an RPC call is received via the multi-scheduler.
	scdsvcdef -p	The definition must be reviewed when the -p option is specified in the scdsvcdef definition command.
tam	tam_max_trnnum	The definition must be reviewed when a TAM file is accessed.
tim	tim_watch_count	The definition must be reviewed in the following cases: When the service_expiration_time operand is applied to the user server When the trn_completion_limit_time operand is applied to the user server When the non-transaction MHP expiration time is applied to the user server When the trn_expiration_time operand is applied to the user server
trn	trn_max_subordinate_count	The definition must be reviewed when transaction processing is performed.
	trn_tran_process_count	The definition must be reviewed when transaction processing is performed.
usrrc User service definition	message_store_buflen	When the added user server sends an RPC call to another user server, the message_store_buflen operand on the other user server must be reviewed.
User service definition	max_socket_descriptors	When the added user server sends an RPC call to another user server, the max_socket_descriptors operand on the other user server must be reviewed.
$DCDIR/lib/sysconf/mcf	max_socket_descriptors	The definition must be reviewed when the number of UAPs that request message transmission from the MCF communication process and the number of operation commands that issue processing requests increase concurrently.
MCF manager common definition	mcfmcomn -p	The definition must be reviewed when an MHP is added. If the value must be increased, the amount of increase is added to the value of the static_shmpool_size operand in the system environment definition (env).

The following table lists the OpenTP1 files that must be reviewed when the degree of parallelism for user servers is changed and indicates under what conditions a review is required.

Table 7-5 OpenTP1 files that must be reviewed when the degree of parallelism for user servers is changed

OpenTP1 file	Condition under which a review is required
System journal file	The file must be reviewed in the following cases: When transaction processing is performed When statistics are acquired
Checkpoint dump file	The file must be reviewed when transaction processing is performed.
XAR file	The file must be reviewed when transaction processing is performed and the XA resource service facility is used.
