Monitoring memory and space on your AIX system

Chapter 13. Monitoring memory and space on your AIX system InfoPrint Manager provides a method for monitoring memory use on your InfoPrint AIX server. This support also provides you the opportunity to define and establish recovery options through exit programs or shell scripts that you can customize and add to the system. AIX allocates space for the printing and monitoring tasks required in an InfoPrint environment through different file systems. A file system is a structure of parent directories, subdirectories, and files. A directory is a unique type of file that contains only the information need to access files or other directories. Directories contain files, subdirectories, or a combination of both. The directory containing a subdirectory is the parent directory. On occasion, you might have to make sure that work files used in printing jobs do not consume too much space on your file systems. For example, PostScript or TIFF job tickets that are ripped for printing might leave work files in the /var/psf file system. Over time, these files can reduce system performance and eventually stop the system. Develop a maintenance strategy with your InfoPrint Solutions Company service representative. Monitoring memory use on your InfoPrint AIX server By default, the Memory Usage tab of the server property notebook is left blank; you must set these values and create the customized shell scripts or programs to activate this support. You can access this support from the InfoPrint Manager Administration GUI: 1. Select Server → Properties. 2. Click the Show more button. 3. Select the Memory Usage tab. From the Memory Usage page, you can specify a low memory threshold percentage and a high memory threshold percentage that cause InfoPrint to invoke a customized exit program or shell script that you can write for your print installation. For example, if the server's system memory usage goes above 60% (the value for the upper memory usage threshold field), InfoPrint invokes a user-customized shell script (the /localtools/uplimit value for the Upper memory usage exit field) that contains specific recovery actions for your print installation. If the server's system memory usage drops below 59% (the value for the lower memory usage threshold field), InfoPrint calls a user-customized shell script (the /localtools/lowlimit value for the Lower memory usage exit field) that contains specific recovery actions for your print installation. This exit usually restores the previous state of the server, undoing temporary changes made by the upper threshold exit. The customized exit programs or shell scripts can do as little or as much as you specify. For example, you might write a script to disable a certain set of printers. The script could also move jobs to other servers. Both the lower-memory-usageexit and upper-memory-usage-exit server attributes allow you to substitute values © Copyright InfoPrint Solutions Company 1998, 2010 137

Chapter 13. Monitoring memory and space on your AIX
system
InfoPrint Manager provides a method for monitoring memory use on your
InfoPrint AIX server. This support also provides you the opportunity to define and
establish recovery options through exit programs or shell scripts that you can
customize and add to the system.
AIX allocates space for the printing and monitoring tasks required in an InfoPrint
environment through different file systems. A
file system
is a structure of parent
directories, subdirectories, and files. A
directory
is a unique type of file that contains
only the information need to access files or other directories. Directories contain
files, subdirectories, or a combination of both. The directory containing a
subdirectory is the parent directory.
On occasion, you might have to make sure that work files used in printing jobs do
not consume too much space on your file systems. For example, PostScript or TIFF
job tickets that are ripped for printing might leave work files in the
/var/psf
file
system. Over time, these files can reduce system performance and eventually stop
the system. Develop a maintenance strategy with your InfoPrint Solutions
Company service representative.
Monitoring memory use on your InfoPrint AIX server
By default, the
Memory Usage
tab of the server property notebook is left blank;
you must set these values and create the customized shell scripts or programs to
activate this support.
You can access this support from the InfoPrint Manager Administration GUI:
1.
Select
Server
Properties
.
2.
Click the
Show more
button.
3.
Select the
Memory Usage
tab.
From the
Memory Usage
page, you can specify a low memory threshold
percentage and a high memory threshold percentage that cause InfoPrint to invoke
a customized exit program or shell script that you can write for your print
installation. For example, if the server's system memory usage goes above 60% (the
value for the
upper memory usage threshold
field), InfoPrint invokes a
user-customized shell script (the
/localtools/uplimit
value for the
Upper
memory usage exit
field) that contains specific recovery actions for your print
installation. If the server's system memory usage drops below 59% (the value for
the
lower memory usage threshold
field), InfoPrint calls a user-customized shell
script (the
/localtools/lowlimit
value for the
Lower memory usage exit
field)
that contains specific recovery actions for your print installation. This exit usually
restores the previous state of the server, undoing temporary changes made by the
upper threshold exit.
The customized exit programs or shell scripts can do as little or as much as you
specify. For example, you might write a script to disable a certain set of printers.
The script could also move jobs to other servers. Both the
lower-memory-usage-
exit
and
upper-memory-usage-exit
server attributes allow you to substitute values
