Putting a database server in the quiescent state

The ccmsrv quiescent command puts the server in a quiescent state so that you can perform administrative tasks.

This topic contains steps for both Windows® and UNIX®.

Read Pre-installation, which is located in the Installing and upgrading section of the Rational® Synergy Information center. Ensure that you have completed the requirements before attempting to use a command.

For more information see:

ccmsrv quiescent

ccmsrv quiescent

Windows

Procedure

  1. Ensure that you are an Informix-Admin group member and are working as local administrator.
  2. On the machine where the Informix® server resides, run theccmsrv quiescent command to put the database server in a quiescent state.

    > ccmsrv quiescent

UNIX

Procedure

  1. Log on the database server as user root.
  2. Set user to informix.
    root# su - informix
    Password: *****

    If you did not set up CCM_HOME and PATH for user informix during installation, set these environment variables now. See Setting environment variables for UNIX.

  3. Send out a message to all server users, alerting them to the state change.

    For example, send a message to all users on the santo and malta databases (the databases on the hydra1 server), as follows:

    $ ccm message -database santo “Putting server in quiescent state in 15 minutes. Please exit from your sessions.”
    $ ccm message -database ?malta “Putting server in quiescent state in 15 minutes. Please exit from your sessions.”
  4. Shut down all databases.
    $ ccmdb shutdown /vol/hydra1/ccmdb/santo
    $ ccmdb shutdown /vol/hydra1/ccmdb/malta
  5. Put the database server in a quiescent state.

    For example, put the hydra1 server in the quiescent state so that you can perform administrative tasks, as follows:

    $ ccmsrv quiescent -s hydra1

    All active Rational Synergy sessions lose their connections to the database server when you change its state.

  6. Exit from user informix.
