Managing OSS Process Scheduling
4. Post a broadcast message to users, using the technique described in Manually
Stopping the OSS File System and the OSS Environment on page 2-3.
This procedure can be used to alter the scheduling priority of any process, including
those released by HP as part of the OSS environment. For example, the following
steps decrease the scheduling priority for the c89 compiler by 15:
1. Put the following lines into a file named /usr/local/script/c89:
#! /bin/sh
nice -n 15 c89 -c *.c
2. Secure the file for only read and execute access by entering:
chmod a=rx /usr/local/script/c89
3. Change the PATH environment variable in /etc/profile to something similar to
the following:
export PATH=/usr/local/script:/bin:/bin/unsupported:/usr/ucb:
/usr/bin
4. Post a broadcast message to users.
Using an OSS Shell Alias
To use a shell alias that changes the default priority of a program, follow these steps:
1. Add an alias in /etc/profile. This alias should have the form:
alias program=nice -n nn object_file_path
program
is the program name usually entered by the user as an OSS shell command.
nn
is the priority adjustment for the process.
object_file_path
is the OSS pathname for the program object file to be executed as the process.
When users without their own .profile file attempt to run the program, your alias
will be found instead of the program file.
2. Notify those users that have their own .profile file about what you are doing so
that they can make comparable changes to their file.
