A.9 Cluster Application Worksheets

The Cluster Application Worksheets are necessary for setting up cluster applications and resources.

The following worksheets are available:

Resource configuration:

Cluster application configuration:

Exclusive relationship configuration for cluster applications:

Global Settings in Configuration Setup:

Note

When setting up resources, if the number of objects of any resource exceeds 50, make sure that the numbers of resource objects and detectors do not exceed the maximum number. The maximum numbers of resource objects and detectors are the following:

  • Cluster applications: 48

  • Resource objects: 500

  • Detectors: 100

You cannot create the configuration of a cluster application which exceeds the values described above.

Calculate the required number of detectors according to the following procedure and make sure that the number of detectors does not exceed the maximum number.

(1) Calculate the required number of detectors for each resource based on the following table.

Resource name

Number of detectors (round up the decimal point)

Cmdline resource

Number of objects / 2 = (a)

Fsystem resource

Number of objects / 5 = (b)

NFS resource (the number of objects with the SHARE flag among the Fsystem resources)

Number of objects / 10 = (c)

Gds resource

Number of objects / 64 = (d)

Gls resource

Number of objects / 64 = (e)

Takeover network resource

Number of objects / 10 = (f)

Procedure resource

Number of objects / 1 = (g)

Process monitoring resource

Number of objects / 1 = (h)

Line Switching Unit resource

Number of objects / 2 = (i)

  • Values such as 2, 5, 10, and 64 in the table indicate the number of the objects which is monitored by a detector of each resource.

  • For details on objects corresponding to each resource, refer to setting worksheets of each resource.

  • The number of objects indicates the total number of all objects of resources which are registered with all cluster applications. The number of detectors is calculated by using the total number of objects.

(2) Add up the number of detectors required for each resource.

                    Number of objects  Number of detectors
  Cmdline               40               (a) 40 / 2 = 20
  Fsystem              190               (b) 190 / 5 = 38
  NFS                    0               (c) 0 / 10 = 0
  Gds                  200               (d) 200 / 64 = 4 (approximately equal to 3.1)
  Gls                   50               (e) 50 / 64 = 1 (approximately equal to 0.7)
  Takeover network       0               (f) 0 / 10 = 0
  Procedure             10               (g) 10 / 1 = 10
  Process monitoring    10               (h) 10 / 1 = 10
  Line Switching Unit    0               (i) 0 / 2 = 0
                       500

In the above example, the total number of detectors is "(a)20 + (b)38 + (c)0 + (d)4 + (e)1 + (f)0 + (g)10 + (h)10 + (i)0 = 83." This configuration is available because the value "83" does not exceed the maximum number of detectors "100."
