Vital Signs HPUX Server Migration

Overview

How to Migrate an existing Vital Signs install from one HPUX production system to a new HPUX pre-production system.

Step 1 - HPUX Software Dependencies

The following software is required to be installed prior to running Vital Signs.

• AskPlus 8.3.3 or Later
• Python 2.7.3
• Python Configobj

Step 2 - File Migration

The following folders should be migrated from the old HPUX system to the new one retaining their file permissions.

• /ASKPLUS/vsdata
• /var/summit/spectrum/LIVE/vsdata

This is possible using the scp command with -rp, r stands for recursive copy and p stands for preserve.

Example scp of /ASKPLUS/vsdata

   su askplus
   scp -rp /ASKPLUS/vsdata askplus@192.168.1.xxx:/ASKPLUS/vsdata

Example scp of /var/summit/spectrum/LIVE/vsdata

   su bolive
   scp -rp /var/summit/spectrum/LIVE/vsdata bolive@192.168.1.xxx:/var/summit/spectrum/LIVE/vsdata

Step 3 - Link Creation

A symbolic link for the jobs directory should be created as root on the new system

   su root
   ln -fs /ASKPLUS/vsdata/jobs /VSJOBS

Step 4 - Verification

Verify that the datachng.so(.sl) exists in the /ASKPLUS directory

  #Example PA-risc
  $ ls -l /ASKPLUS/datachng*
  -rwxr-xr-x   1 askplus    users        69792 Jan 19  2012 /ASKPLUS/datachng.sl

  #Example Itanium
  $ ls -l /ASKPLUS/datachng*
  -rwxr-xr-x   1 askplus    users        69792 Jan 19  2012 /ASKPLUS/datachng.so

NOTE : If you are migrating from PA-risc to ITANIUM you need to download the datachng.so file : Download datachng.so

NOTE : If you are migrating from ITANIUM to PA-risc you need to download the datachng.sl file : Download datachng.sl

Verify that the following profiles exist in the /ASKPLUS/vsrvtcp.ini file

• [vsdata_test]
• [vsdata_live]
• [vsdata_test_eom]
• [vsdata_live_eom]
• [vsdata_test_restore]
• [vsdata_live_restore]

   su askplus
   grep vsdata_ /ASKPLUS/vsrvtcp.ini
   

If they do NOT exist, copy them from the existing vsrvtcp.ini on the old system OR do the following to add them and then compare them to the profiles on the old system

   su askplus
   cd /ASKPLUS/vsdata
   ./vsinstall
   
   #Verify again
   grep vsdata_ /ASKPLUS/vsrvtcp.ini
   

Verify that the following files have 755 permissions

- /ASKPLUS/vsdata/scripts/vsftp - /ASKPLUS/vsdata/scripts/vsreload

   $ ls -l /ASKPLUS/vsdata/scripts/vs*
   -rwxr-xr-x   1 askplus    users         7951 Oct 17 10:23 /ASKPLUS/vsdata/scripts/vsftp
   -rwxr-xr-x   1 askplus    users        11633 Sep  6 11:07 /ASKPLUS/vsdata/scripts/vsreload

Verify that the /VSJOBS link exists

   $ ls -l /VSJOBS
   lrwxr-xr-x   1 root       sys             20 Apr 21  2011 /VSJOBS -> /ASKPLUS/vsdata/jobs

Step 5 - Test Run Daily / Modify UC4 Jobs

Now that all of the prior steps have been completed successfully, run a test daily extract for History and Membership Analysis

   su bolive
   cd /var/summit/spectrum/LIVE
   /VSJOBS/JVSLOAD_HIST
   
   #When JVSLOAD_HIST finishes, run
   /VSJOBS/JVSLOAD_MBRSHLN

If these test runs do not have any issues then update the UC4 jobs to point at the new Host and give yourself a big pat on the back.
