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
