The following document describes the procedure used to move the EGATE Production database environment from the Mt Xia Franklin (MXF)data center to the Disaster Recovery provisions at Mt Xia Dallas (MXD) Data Center. The DR provisions at MXD normally run the Egate pre-production environment.

  1. The first phase of this process is to shutdown the pre-production EGATE database and start the production EGATE database environment in the DR provision.

  2. The second phase of this process is to shutdown the production EGATE database in the DR provision and restart the pre-production EGATE database environment.

Phase 1

- Shutdown the pre-production EGATE database and start the production EGATE database environment in the DR provision.


Phase 1 Start Time:
Phase 1 Duration: 








    




  1.   Contact SAN group to turn off the
Tru-Copy mirroring of the production EGATE database drives.

  2.  Login to mxdaaega01 on the console as root. You will need to
install and run the Hardware Management Console (HMC) client to be able
to access the console of these machines.  The HMC client can be
downloaded from the following url:
    

    
http://mxdlahmc01.tu.com/remote_client.html

    3. 


  3.  Notify Users the DR is about to occur

    

     wall
    
A disaster has occurred and the pre-production environment is
    
being reconfigured as production NOW. Please LOG OFF.
