The following document describes the procedure used to move the EGATE Pre-Production database environment from the temporary Proof-of-Concept architecture running on the p590, back to the original 6M2 platforms, then permanently back to the p590 with the Production Disaster Recovery provisions in place.

  1. The first phase of this process is to shutdown the EGATE database environment on the POC platform. The purpose of this phase is to quantify the time required to perform each step of this process. The timing information is needed for planning the movement of the EGATE Production environment to the new Power 5 architecture.

  2. Restart the EGATE Pre-Prod environment on the Power 4 architecture and validate. Again the purpose is to quantifiy the time required to perform this phase.

  3. Shutdown the EGATE Pre-Prod environment on the Power 4 architecture, modify the Power 5 systems to EXACTLY replicate the Power 4 systems.

  4. Restart the Pre-prod environment on the Power 5 systems.

  5. Perform Disaster Recovery test of Production environment onto the new Power 5 Architecture.

  6. Deconfigure production environment on Power 5 architecture and restart the pre-prod environment

EGATE database servers
    


    

    

    Phase 4 Start Time: 16:15 - 18:55

    Phase 4 Duration: 160m (2h 40m)

    


    

      




    1.  Login to ddcaaega01 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://ddclahmc01.tu.com/remote_client.html

      2. 


    2.  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.


      
      

      3. 


    3.  Change to the DR scripts directory for the target server:

      

     $ cd /usr/lpp/dr/mdctxudb85
     

      4. 


    4.  Execute the deconfiguration phase of the DR.  The options shown
indicate the deconfiguration should kill all processes (k), varyoff and
export VGs (e), unmount filesystems (m), deconfigure the network
adapters (n), delete any existing IQ directories (d), and to do it all
in verbose mode (v).

      

      

      Start Time: 16:18

      Duration: 77m

      
     $ ./OCIDR -hkemndv deconfig
     

      5. 

    5.  Check to see that HACMP is down, user processes were killed,
     all non-rootvg file systems were unmounted,
     all non-static volume groups were varied off and exported.  The 
     remaining volume groups may include one or more of the following: 
     rootvg, altinst_rootvg, egate1[0-9][0-9]vg_dr.
     
      6. 


    6.  Execute the configuration phase of the DR and import the volume
groups.  The options shown indicate the configuration should import the
VGs, LVs, and FSs (i), mount the filesystems (m), configure the network
adapters in HACMP mode (N), install the configuration files (r), start
the applications (a), create the home directories (o), create the IQ
directories (d), change the hostname (u), and to do it all in verbose
mode (v).

      

      

      Start Time: 17:35

      Duration: 1m

      
     $ ./OCIDR -IGmNraoduv config
     

      7. 

    7.  Check to see that all volume groups were imported and varied on,
     all file systems were mounted,
     network addresses were changed,
     IQ directories were created,
     configuration scripts were installed,
     and background daemons were refreshed.
     
      8. 


    8.  The Oracle parallel server requires the disks and logical volumes 
be owned by the oracle user.  Execute the following script to change the
disk ownerships:

      

      

      Start Time: 17:36

      Duration: 1m

      
     $ /usr/lpp/dr/helpers/fixForOracle.sh
     

      9. 


    9.  After HACMP startup is complete, initialize the Oracle environment
     by running the following script:

      

      

      Start Time: 17:36

      Duration: 1m

      

     $ mount ddcapnim01:/export/cdimages /mnt
      
     $ cd /mnt/Oracle8i/CD1 # DO NOT SKIP
      
     $ ./rootpre.sh
     

      10. 


    10.  After the OCIDR script has completed on ALL Oracle Parallel Server
nodes, start HACMP on this node:

    15.  Check to see that HACMP is down, user processes were killed,
     all non-rootvg file systems were unmounted,
     all non-static volume groups were varied off and exported.  The 
     remaining volume groups may include one or more of the following: 
     rootvg, altinst_rootvg, egate1[0-9][0-9]vg_dr.
     
      16. 


    16.  Execute the configuration phase of the DR and import the volume
groups.  The options shown indicate the configuration should import the
VGs, LVs, and FSs (i), mount the filesystems (m), configure the network
adapters in HACMP mode (N), install the configuration files (r), start
the applications (a), create the home directories (o), create the IQ
directories (d), change the hostname (u), and to do it all in verbose
mode (v).

     configuration scripts were installed,
     and background daemons were refreshed.
     
      18. 


    18.  The Oracle parallel server requires the disks and logical volumes 
be owned by the oracle user.  Execute the following script to change the
disk ownerships:


      

      

      Start Time: 17:19

      Duration: 2m

      

     $ /usr/lpp/dr/helpers/fixForOracle.sh

      Duration: 2m

      

     $ mount ddcapnim01:/export/cdimages /mnt

     $ ./rootpre.sh

     

      20. 


    20.  After the OCIDR script has completed on ALL Oracle Parallel Server
nodes, start HACMP on this node:


      

      

      Start Time: 17:47
