Configuring the Share-Based Policy From the Command Line

Use QMON to configure the share tree policy, because a hierarchical tree is well-suited for graphical display and for editing. However, if you need to integrate share tree modifications in shell scripts, for example, you can use the qconf command and its options.

To configure the share-based policy from the command line, use the qconf command with appropriate options.

• The qconf options -astree, -mstree, -dstree, and -sstree, enable you to do the following:

  • Add a new share tree

  • Modify an existing share tree

  • Delete a share tree

  • Display the share tree configuration

  See the qconf(1) man page for details about these options. The share_tree(5) man page contains a description of the format of the share tree configuration.

• The -astnode, -mstnode, -dstnode, and -sstnode options do not address the entire share tree, but only a single node. The node is referenced as path through all parent nodes down the share tree, similar to a directory path. The options enable you to add, modify, delete, and display a node. The information contained in a node includes its name and the attached shares.

• The weighting of the usage parameters CPU, memory, and I/O are contained in the scheduler configuration as usage_weight. The weighting of the half-life is contained in the scheduler configuration as halftime. The compensation factor is contained in the scheduler configuration as compensation_factor. You can access the scheduler configuration from the command line by using the -msconf and the -ssconf options of qconf. See the sched_conf(5) man page for details about the format.
