Remotely executing tasks

The IBM® Spectrum Symphony execution application provides the ability to start and control remote execution of executable files. Each application consists of an execution service and an executable file that are distributed among compute hosts.

About this task

From the cluster management console, use the workload submission panel that allows a single command to be submitted per session to run the executable file. You can also enter associated pre- and post- commands, as well as environment variables and their values.

Be aware that the functionality of the workload submission panel in the cluster management console differs from the CLI subcommand where Guest is the user name and password; from the cluster management console, the default submission user and password is the user account and password that you used to sign in to the cluster management console.

The cluster management console can retrieve log files that are created by the execution service for each session.

Note: Only a single command can be submitted per session from the cluster management console. If you need to send multiple concurrent commands, ensure that you open additional submission dialogs.
