Administering Projects and Tasks
This chapter describes how to use the project and task facilities of Solaris resource management.
The following topics are covered.
For an overview of the projects and tasks facilities, see Chapter 2, Projects and Tasks (Overview).
Note - If you are using these facilities on a Solaris system with zones installed, only processes in the same zone will be visible through system call interfaces that take process IDs when these commands are run in a non-global zone.
Administering Projects and Tasks (Task Map)
Task | Description | For Instructions |
|---|---|---|
View examples of commands and options used with projects and tasks. | Display task and project IDs, display various statistics for processes and projects that are currently running on your system. | |
Define a project. | Add a project entry to the /etc/project file and alter values for that entry. | |
Delete a project. | Remove a project entry from the /etc/project file. | |
Validate the project file or project database. | Check the syntax of the /etc/project file or verify the uniqueness of the project name and project ID against the external naming service. | |
Obtain project membership information. | Display the current project membership of the invoking process. | |
Create a new task. | Create a new task in a particular project by using the newtask command. | |
Associate a running process with a different task and project. | Associate a process number with a new task ID in a specified project. | |
Add and work with project attributes. | Use the project database administration commands to add, edit, validate, and remove project attributes. |
Example Commands and Command Options
This section provides examples of commands and options used with projects and tasks.
Command Options Used With Projects and Tasks
ps Command
Use the ps command with the -o option to display task and project IDs. For example, to view the project ID, type the following:
# ps -o user,pid,uid,projid USER PID UID PROJID jtd 89430 124 4113 |
id Command
Use the id command with the -p option to print the current project ID in addition to the user and group IDs. If the user operand is provided, the project associated with that user's normal login is printed:
# id -p uid=124(jtd) gid=10(staff) projid=4113(booksite) |
pgrep and pkill Commands
To match only processes with a project ID in a specific list, use the pgrep and pkill commands with the -J option:
# pgrep -J projidlist # pkill -J projidlist |
To match only processes with a task ID in a specific list, use the pgrep and pkill commands with the -T option:
# pgrep -T taskidlist # pkill -T taskidlist |
prstat Command
To display various statistics for processes and projects that are currently running on your system, use the prstat command with the -J option:
% prstat -J

Using cron and su With Projects and Tasks
cron Command
The cron command issues a settaskid to ensure that each cron, at, and batch job executes in a separate task, with the appropriate default project for the submitting user. The at and batch commands also capture the current project ID, which ensures that the project ID is restored when running an at job.
