Note

Valid number of processes is the number of system service processes per node when one OpenTP1 instance is operating within a node.

#1

Although there is usually only one process during operation, it might seem that multiple processes temporarily exist in the following cases. This is because the process starts the OpenTP1 process.

- When OpenTP1 is started by using the dcstart command

- When the user server is started by using the dcsvstart command

- When the process of a non-resident server is started

#2

The valid number of processes is 0 when Y is specified in the jnl_fileless_option operand in the system common definition.

#3

The value is determined using the following equation:

a x b

a: 2 when journals are duplicated; 1 when journals are not duplicated.

b: Maximum dispersed files for parallel access when using the parallel access facility for system journal files.

#4

This number is obtained from the following formula:

a b c

a: 2 if a journal is duplicated; 1 if a journal is not duplicated.

b: Maximum number of distributions in the parallel access facility for archive journal files.

c: Number of resources specified in the global archive journal service definition.

#5

The process runs in a node which has a global archive journal service.

#6

The valid number of processes is 1 when Y is specified in the jnl_auto_unload operand in the system journal service definition.

#7

Same as the number of archive-journal source nodes that are being transferred to the archive-journal target node.

#8

This file is a process for obtaining the trace. Although this process is created in extension with prcd, the information obtained by this process cannot be displayed by OpenTP1 prcls command. To display the details, execute the operating system's ps command.

#9

The valid number of processes is as follows:

When N is specified in the prf_trace operand in the system common definition

- The valid number of processes is 0.

When Y is specified in the prf_trace operand in the system common definition

- When MCF is not used, the valid number of processes is 8.

- When MCF is used, the valid number of processes is 9.

#10

When TP1/Messaging is used, the file name is fixed to mcfutcpd or mcfupsvd.
