Starting PXMCOM

all the online mananagement functions needed in the Pathway/XM environment.

(PATHCOM commands are not needed and should not be used.)

Starting PXMCOM

After you have configured your Pathway/XM environment by writing a PXMCFG

source file and running PXMCFG to create the SuperCTL file, you can start a

PXMCOM process by issuing an implicit RUN command to TACL. For example, the

following command starts a PXMCOM process in the current default volume and

subvolume:

> PXMCOM

The operating system responds to your command by creating your PXMCOM process.

You can enter this command from your terminal, as shown in the example.

Alternatively, you can create a command file that contains this command (as well as

others) and then request execution of the commands in that file. The following

examples show the interactive use of PXMCOM.

When PXMCOM starts, it displays the PXMCOM banner message on your screen and

presents two greater-than signs as a prompt for your first PXMCOM command, as

shown in the following example:

8> PXMCOM

PXMCOM - T0223D48 - (31MAR2000)

For detailed syntax of the command you use to start PXMCOM, refer to Starting

PXMCOM on page 11-3.

After starting PXMCOM, you must establish communication with the SuperCTL file for

your Pathway/XM environment by using an OPEN command. For example, the

following command establishes communication with the SuperCTL file named SCTL1:

>> OPEN SCTL1

Alternatively, you can issue the OPEN command in the same TACL command line you

use to start PXMCOM. For example, the following command line both starts

PXMCOM and establishes communication with the SuperCTL file named SCTL1:

> PXMCOM OPEN SCTL1

Figure 7-1 shows the communication path established by running PXMCOM and

opening the SuperCTL file SCTL1.

Caution. Using PATHCOM commands to change the configuration or to change the state of

objects can interfere with Pathway/XM operations and produce unpredictable results; it can

cause the Pathway/XM environment to be unbalanced and uncontrollable from PXMCOM.

Moreover, the output of informational PATHCOM commands such as INFO, STATUS, and

STATISTICS can be confusing or misleading in the Pathway/XM environment.
