Monitoring Execution Hosts With qhostUse the qhost command to retrieve a quick overview of the execution host status:
This command produces output that is similar to the following example: Example 1-1 Sample qhost Output
See the qhost(1) man page for a description of the output format and for more options. Invalid Host NamesThe following is a list of host names that are invalid, reserved, or otherwise not allowed to be used:
Killing Daemons From the Command LineTo kill grid engine system daemons from the command line, use one of the following commands:
You must have manager or operator privileges to use these commands. See Chapter 4, Managing User Access for more information about manager and operator privileges.
If you want to wait for any active jobs to finish before you run the shutdown procedure, use the qmod -dq command for each cluster queue, queue instance, or queue domain before you run the qconf sequence described earlier. For information about cluster queues, queue instances, and queue domains, see Configuring Queues.
The qmod -dq command prevents new jobs from being scheduled to the disabled queue instances. You should then wait until no jobs are running in the queue instances before you kill the daemons. Restarting Daemons From the Command LineLog in as root on the machine on which you want to restart grid engine system daemons. Type the following commands to run the startup scripts:
These scripts looks for the daemons normally running on this host and then start the corresponding ones. Basic Cluster ConfigurationThe basic cluster configuration is a set of information that is configured to reflect site dependencies and to influence grid engine system behavior. Site dependencies include valid paths for programs such as mail or xterm. A global configuration is provided for the master host as well as for every host in the grid engine system pool. In addition, you can configure the system to use a configuration local to each host to override particular entries in the global configuration. The cluster administrator should adapt the global configuration and local host configurations to the site's needs immediately after the installation. The configurations should be kept up to date afterwards. The sge_conf(5) man page contains a detailed description of the configuration entries. Displaying a Cluster Configuration With QMONOn the QMON Main Control window, click the Cluster Configuration button. The Cluster Configuration dialog box appears. Figure 1-6 Cluster Configuration Dialog Box ![]() In the Host list, select the name of a host. The current configuration for the selected host is displayed under Configuration. Displaying the Global Cluster Configuration With QMONOn the QMON Main Control window, click the Cluster Configuration button. In the Host list, select global. The configuration is displayed in the format that is described in the sge_conf(5) man page. Adding and Modifying Global and Host Configurations With QMONIn the Cluster Configuration dialog box (Figure 1-6), select a host name or the name global, and then click Add or Modify. The Cluster Settings dialog box appears. ![]() The Cluster Settings dialog box enables you to change all parameters of a global configuration or a local host configuration. All fields of the dialog box are accessible only if you are modifying the global configuration. If you modify a local host, its configuration is reflected in the dialog box. You can modify only those parameters that are feasible for local host changes. If you are adding a new local host configuration, the dialog box fields are empty. The Advanced Settings tab shows a corresponding behavior, depending on whether you are modifying a configuration or are adding a new configuration. The Advanced Settings tab provides access to more rarely used cluster configuration parameters. ![]() When you finish making changes, click OK to save your changes and close the dialog box. Click Cancel to close the dialog box without saving changes. See the sge_conf(5) man page for a complete description of all cluster configuration parameters. Deleting a Cluster Configuration With QMONOn the QMON Main Control window, click the Cluster Configuration button. In the Host list, select the name of a host whose configuration you want to delete, and then click Delete. | |||||||||||
