Open System Services Porting Guide (G06.29+, H06.06+, J06.03+)

The following examples present different ways of using the OSS gtacl utility.
• The following command executes a single Guardian command:
gtacl -c 'FUP SECURE $DATA01.REPORT.JAN94,"AOAO"'
The single quotes (' ') are used to avoid any special processing of the $ and " characters by
the shell.
• The following command line executes the Guardian STATUS command and directs the output
to the grep utility by using a pipe character (|). grep finds all of the processes (from the
STATUS command output) currently executing the FUP program:
gtacl -c 'STATUS *' | grep FUP
• The following command line creates the /tmp/systemfiles file and places in it the list of
files on the $SYSTEM volume:
gtacl -p FUP INFO \$SYSTEM.\*.\* > /tmp/systemfiles
• A Guardian command file can be started using gtacl. In the following example, the command
file $DATA01.REPORTS.MONTHLY is executed. Be sure to precede the filename with a
backslash (\):
gtacl -c 'OBEY \$DATA01.REPORTS.MONTHLY' &
The ampersand (&) instructs that the command file be run in background. When using an
ampersand, control returns to the user immediately after the command is initiated.
For a complete description of the gtacl utility, refer to the gtacl(1) reference page either online
or in the Open System Services Shell and Utilities Reference Manual.
Running OSS Processes With Guardian Attributes
The OSS run or runv utility enables you to execute OSS programs with attributes specific to the
Guardian environment, such as process names and processor numbers. Following are examples
of using the built-in run utility.
• In the following example, the Guardian process name $SVR1 is assigned to an OSS process:
run -name=/G/svr1 server
• The following example specifies a processor in which a process is to run. This process executes
in processor 5 with the Guardian process name $SVR2:
run -name=/G/svr2 -cpu=5 server
• The following example starts the testprog program running under the Inspect debugger on
TNS/R systems or the Native Inspect debugger on TNS/E systems, or, if a Visual Inspect client
connection has been established, the program is started under the Visual Inspect debugger:
run -debug -inspect=on testprog
The Open System Services Shell and Utilities Reference Manual contains a complete description
of the run(1) and runv(1) utilities. Additionally, the Open System Services User’s Guide provides
examples of using the run utility and descriptions of the run options.
Using OSS Commands to Manage Guardian Objects
You can use some OSS utilities to manage Guardian processes and files as well as to manage
OSS objects. To manage Guardian objects, frequently requires that you use the -W parameter,
described following.
Accessing Guardian files is made possible by the /G and /E directories. This subsection describes
some of the more frequently used interoperability features. For a detailed discussion of the OSS
utilities described in this subsection, refer to the Open System Services User’s Guide and Open
System Services Shell and Utilities Reference Manual.
