(2) Acquiring the attribute file to be edited and setting the attributes

• Acquiring the attribute file

  Execute the following command to acquire a WAR attribute file:

  Execution format

  cjgetappprop [server-name] [-nameserver provider-URL] -name J2EE application-name -type war -resname WAR-display-name -c path-of-the-WAR-attribute-file

  Example of execution

  cjgetappprop MyServer -name adder -type war -resname adder_war -c C:\home\adder_war.xml

• Setting the attributes

  Execute the following command to apply the values of the WAR attribute file:

  Execution format

  cjsetappprop [server-name] [-nameserver provider-URL] -name J2EE application-name -type war -resname WAR-display-name -c path-of-the-WAR-attribute-file

  Example of execution

  cjsetappprop MyServer -name adder -type war -resname adder_war -c C:\home\adder_war.xml

(3) Attribute settings to be edited

The following table describes the property settings for controlling the number of threads executed concurrently for each URL group (<urlgroup-thread-control>):

Items	Mandatory	Corresponding tags
Definition name	Y	<urlgroup-thread-control-name>
Maximum number of threads executed concurrently	Y	<urlgroup-thread-control-max-threads>
Number of exclusive threads	Y	<urlgroup-thread-control-exclusive-threads>
Size of the pending queue of each URL group	Y	<urlgroup-thread-control-queue-size>
URL pattern	Y	<urlgroup-thread-control-mapping> - <url-pattern>

For details on the property settings, see 3.7.1 Specifications of the HITACHI WAR Property file in the uCosminexus Application Server Application and Resource Definition Reference Guide.

(4) Notes

• The number of threads executed by controlling the number of threads executed concurrently for each URL group, is included in the number of threads executed for each Web application. As a result, when one thread is executed for each URL group, one thread is also executed for each Web application in this Web application.

• Set the number of threads executed concurrently for each URL group in the following range:

  • Maximum number of threads executed concurrently

    The range for specifying the maximum number of threads executed concurrently is as follows:

    1 ≤ Sum total of the maximum number of threads executed concurrently for each URL group ≤ Maximum number of threads executed concurrently for each Web application

  • Number of exclusive threads

    The range for specifying the number of exclusive threads is described below.

    Both condition 1 and condition 2 need to be fulfilled.

    Condition 1: 
    When the maximum number of threads executed concurrently for each Web application = Number of exclusive threads for each Web application
      0 ≤ Number of exclusive threads for each URL group ≤ Maximum number of threads executed concurrently for each URL group
    When maximum number of threads executed concurrently for each Web application ≠ Number of exclusive threads for each Web application
      0 ≤ Number of exclusive threads for each URL group < Maximum number of threads executed concurrently for each URL group
     
    Condition 2:
      Sum total of the number of exclusive threads for each URL group ≤ Number of exclusive threads for each Web application
