4.4.3 Switching from Push to Pull

This section explains how to switch from Push mode to Pull mode during operation.


Required privileges

Windows

The user must have the privileges of a member of the Administrators group.

UNIX

The user must have the privileges of the system administrator (superuser).


Note

If redundant Manager operation is being performed, first cancel the redundant operation, then switch from Push to Pull, and then set up redundant operation again.

To cancel redundancy, use the procedure described in "sqcHaSetup (Agent/Proxy Manager Setup Command for Redundant Manager Operation)" in the Reference Guide.


4.4.3.1 Tasks to perform on the Manager

Define the agentlist.cfg file by referring to "4.4.1 Defining Pull communications".


4.4.3.2 Tasks to perform on the Agent or Proxy Manager

Before performing this procedure

If Agent or Proxy Manager resident processes are running, refer to "A.8 How to Start and Stop Resident Processes" and stop the service or daemon and the thttpd service if it is being used. Also check that the resident processes have stopped correctly.


Procedure

  1. Changing the definition file

    The definition file is stored in the following location:

    Windows

    <Variable file storage directory>\control\DSAconfiguration.txt

    UNIX

    /etc/opt/FJSVssqc/DSAconfiguration.txt


    The method used to change the definition file is explained below.

    Make a backup copy of DSAconfiguration.txt before making any changes to the file.


    1. Add "*" (asterisk) to the first letter of a section name in the [DsaForwarder] and [DsaForwarder_sum] section.

      • Before modification

        [DsaForwarder]

        [DsaForwarder_sum]

      • After modification

        [*DsaForwarder]

        [*DsaForwarder_sum]

    2. Delete "*" (asterisk) from the first letter of a section name in the [DelayXfer] section.

      • Before modification

        [*DelayXfer]

      • After modification

        [DelayXfer]


  2. Definition of the using port number

    Define the port number which is used for the Pull communication indicated in the "4.4.1 Defining Pull communications" to following files.

    Windows

    %SystemRoot%\system32\drivers\etc\services

    UNIX

    /etc/services

    Definition method

    thttpd 23440/tcp


  3. Execute the commands

    Windows

    Use the following method to set up the Pull communication environment. (This will increase the security risk.)

    Execute the following two commands:

    C:\> <Installation directory>\bin\sqcSetFileSec.exe -u <Variable file storage directory>\temp


    C:\> <Installation directory>\bin\sqcSetFileSec.exe -u <Variable file storage directory>\spool\Delayxfer


    UNIX

    Execute the Pull communication setup command shown below. (This will increase the security risk.)

    Execute the following command:

    /opt/FJSVssqc/bin/pullsetup.sh

    Note

    • Web server settings are needed when Pull operation is used. Perform the setup procedure by referring to "Chapter 5 Setting Up the Communication Environment".

    • If redundant Manager operation is being performed, first cancel the redundant operation, then switch from Push to Pull, and then set up redundant operation again.

  4. Start the Agent/Proxy Manager service or daemon and confirm that it operates normally

    Start the service or daemon, and the thttpd service (if it is to be used), by referring to "A.8 How to Start and Stop Resident Processes". Also check that the resident processes have started correctly.
