lsclass Command

Purpose

List Workload Management classes and their limits.

Syntax

lsclass [ -C | -D | -f ] [ -r ] [ -d Config_Dir ] [ -S SuperClass ] [ Class ]

Description

The lsclass command, with no argument, returns the list of superclasses, one per line. With a class name as argument, it prints the class. The subclasses can be displayed with the -r (recursive) flag, or with the -S Superclass flag.

When WLM is started, if an empty string is passed as the name of the configuration with the -d flag, lsclass lists the classes defined in the in-core WLM data structures.

The lsclass command does not require any special level of privilege and is accessible for all users.

Flags


-C Displays the class attributes and limits in colon-separated records, as follows: 

lsclass -C myclass 
#name:description:tier:inheritance:localshm:authuser:authgroup:adminuser:admingroup:rset:
 
CPUshares:CPUmin:CPUsoftmax:CPUhardmax:memoryshares:memorymin:memorysoftmax: 
memoryhardmax:DiskIOshares:DiskIOmin:DiskIOsoftmax:DiskIOhardmax 
myclass::0:no:root:system:root:system::-:0:50:100:4:10:50:75:6:0:100:100
-d Config_Dir Use /etc/wlm/Config_Dir as alternate directory for the definition files. If an empty string is passed (for exampl, -d ""), lsclass lists the classes defined in the in-core WLM data structures. If this flag is not present, the current configuration files in the directory pointed to by /etc/wlm/current are used.
-D Displays the default values for the class attributes and limits in colon-separated records. Any other flag or argument used in conjunction with -D is ignored. For example: 

lsclass -D
#name:description:tier:inheritance:authuser:authgroup:adminuser:admingroup:rset:
 
CPUshares:CPUmin:CPUsoftmax:CPUhardmax:memoryshares:memorymin:memorysoftmax: 
memoryhardmax:DiskIOshares:DiskIOmin:DiskIOsoftmax:DiskIOhardmax  
 
 

::0:no:no::::::-:0:100:100:-:0:100:100:-:0:100:100
-f Displays the output in stanzas, with each stanza identified by a class name. Each Attribute=Value pair is listed on a separate line: 

Class:
       attribute1=value
       attribute2=value
       attribute3=value
-r Displays, recursively, the superclasses with all their subclasses. When specifying -r:
  • If Class is not specified, lsclass shows all the superclasses with all their subclasses.
  • If the name of a superclass is specified, lsclass displays the superclass with all its subclasses.
  • If the name of a subclass is specified, -r is ineffective (displays only the subclass).
-S SuperClass Restricts the scope of the command to the subclasses of the specified superclass. Only subclasses are shown with the -S flag.
