To start the automatic backup process, type the following command on the sge_qmaster host:
backup-conf is the full path to the backup configuration file. Note - You do not need to shut down any of the grid engine system daemons before you back up your configuration files. Your backup is created in the directory specified by BACKUP_FILE. A backup log file called install.pid is also created in this directory. pid is the process ID number. Using Files and Scripts for Administration TasksThis section describes how to use files and scripts to add or modify grid engine system objects such as queues, hosts, and environments. You can use the QMON graphical user interface to perform all administrative tasks in the grid engine system. You can also administer a grid engine system through commands you type at a shell prompt and call from within shell scripts. Many experienced administrators find that using files and scripts is a more flexible, quicker, and more powerful way to change settings. Using Files to Add or Modify ObjectsUse the qconf command with the following options to add objects according to specifications you create in a file:
Use the qconf command with the following options to modify objects according to specifications you create in a file:
The -Ae and -Me options add or modify execution hosts. The -Aq and -Mq options add or modify queues. The -Au and -Mu options add or modify usersets. The -Ackpt and -Mckpt options add or modify checkpointing environments. The -Ap and -Mp options add or modify parallel environments. Use these options in combination with the qconf -s command to take an existing object and modify it. You can then update the existing object or create a new object. Example 7-1 Modifying the Migration Command of a Checkpoint Environment
Using Files to Modify Queues, Hosts, and EnvironmentsYou can modify individual queues, hosts, parallel environments, and checkpointing environments from the command line. Use the qconf command in combination with other commands.
The -Me and -me options modify execution hosts. The -Mq and -mq options modify queues. The -Mckpt and -mckpt options modify checkpointing environments. The -Mp and -mp options modify parallel environments. The difference between the uppercase -M options and the lowercase -m options controls the qconf command's result. Both -M and -m mean modify, but the uppercase -M denotes modification from an existing file, whereas the lowercase -m does not. Instead, the lowercase -m opens a temporary file in an editor. When you save any changes you make to this file and exit the editor, the system immediately reflects those changes. However, when you want to change many objects at once, or you want to change object configuration noninteractively, use the qconf command with the options that modify object attributes (such as -Aattr, -Mattr, and so forth). The following commands make modifications according to specifications in a file:
The following commands make modifications according to specifications on the command line:
The -Aattr and -aattr options add attributes. The -Mattr and -mattr options modify attributes. The -Rattr and -rattr options replace attributes. The -Dattr and -dattr options delete attributes. filename is the name of a file that contains attribute-value pairs. attribute is the queue or host attribute that you want to change. value is the value of the attribute you want to change. The -aattr, -mattr, and -dattr options enable you to operate on individual values in a list of values. The -rattr option replaces the entire list of values with the new one that you specify, either on the command line or in the file. Example 7-2 Changing the Queue Type The following command changes the queue type of tcf27-e019.q to batch only:
Example 7-3 Modifying the Queue Type and the Shell Start Behavior The following command uses the file new.cfg to modify the queue type and the shell start behavior of tcf27-e019.q:
Example 7-4 Adding Resource Attributes The following command adds the resource attribute scratch1 with a value of 1000M and the resource attribute long with a value of 2:
Example 7-5 Attaching a Resource Attribute to a Host The following command attaches the resource attribute short to the host with a value of 4:
Example 7-6 Changing a Resource Value The following command changes the value of scratch1 to 500M, leaving other values unchanged:
