IBM LoadLeveler for AIX 5L: Using and Administering

Building a job command file

Before you can submit a job or perform any other job related tasks, you need to build a job command file. A job command file describes the job you want to submit, and can include LoadLeveler keyword statements. For example, to specify a binary to be executed, you can use the executable keyword, which is described later in this section. To specify a shell script to be executed, the executable keyword can be used; if it is not used, LoadLeveler assumes that the job command file itself is the executable.

The job command file can include the following:

• LoadLeveler keyword statements: A keyword is a word that can appear in job command files. A keyword statement is a statement that begins with a LoadLeveler keyword. These keywords are described in Job command file keywords.
• Comment statements: You can use comments to document your job command files. You can add comment lines to the file as you would in a shell script.
• Shell command statements: If you use a shell script as the executable, the job command file can include shell commands.
• LoadLeveler Variables: See Job command file variables for more information.

You can build a job command file either by using the Build a Job window on the GUI or by using a text editor.
