3.22 Upgrading Moab Insight (RPM)

This topic provides instructions to upgrade Moab Insight to the latest release version using the RPM upgrade method. It includes instructions for migrating your database schema to a new version if necessary.

Because many system-level files and directories are accessed during the installation, the instructions in this guide should be executed with root privileges.

You will see that the instructions execute commands as the root user. Please note that the same commands will work for a non-root user with the sudo command.

3.22.1 Upgrade the Insight Server

Do the following:

  1. On the Moab Server Host, stop Moab from sending messages to Insight. 
    [root]# mschedctl -s
  2. On the Insight Server Host, do the following:
    1. If you have not already done so, complete the steps to prepare the Insight Server Host for the upgrade. See 3.2 Preparing the Host – Typical Method or 3.4 Preparing the Host – Offline Method.
    2. Stop Insight
      [root]# service insight stop
    3. Back up the Insight home directory. 
      [root]# cp -r /opt/insight /opt/insight-9.0.1-backup
    4. Back up your Insight databases
      [root]# su - postgres
[postgres]$ pg_dump moab_insight > /tmp/moab_insight_9.0.1.dump
[postgres]$ pg_dump moab_insight_reference > /tmp/moab_insight_reference_9.0.1.dump
[postgres]$ exit
[root]# mv /tmp/moab_insight_9.0.1.dump /opt
[root]# mv /tmp/moab_insight_reference_9.0.1.dump /opt
[root]# mongodump --username insight_user --password secret4 -d insight --out /opt/insight_9.0.1.mongo.dump
    5. Install the upgrade
      [root]# yum update moab-insight*
    6. Merge the new configuration from /opt/insight/etc/config.groovy.rpmnew into /opt/insight/etc/config.groovy.
    7. Verify the insight user has read access to the /opt/insight/etc/config.groovy file.
      [root]# ls -l /opt/insight/etc/config.groovy
-rw-r--r--. 1 insight insight 3787 Jan 24 17:51 /opt/insight/etc/config.groovy
    8. Verify the following line is added to the end of /opt/insight/etc/insight.conf:
      JAVA_HOME="/usr/java/latest"

    9. Optional. Postpone the database upgrade.

      Upon starting, Insight will detect what version the PostgreSQL and Mongo Insight database schemas are. If the schemas are not compatible with the current version, Insight will upgrade the schemas, including all data contained therein.

      • If upgrading from 9.0.1 this could take anywhere from several minutes to several hours, depending on how large a system you have.
      • If upgrading from 9.0.0 the upgrade could take days.

      If you cannot wait that long and you don't have immediate need for the old data, you can postpone the database upgrade and allow the Insight upgrade to continue.

      To postpone the database upgrade, set the following in the /opt/insight/etc/config.groovy file.

      insight.skip.database.migration = true

      When you have time to perform the database upgrade, set this property back to "false" and restart Insight.

    10. Start Insight. 
      [root]# service insight start

    11. If you decided not to postpone the database upgrade, then wait for and confirm the database upgrade completed. All data must be transferred before the upgrade is complete.

      To track the upgrade process, view /opt/insight/log/insight.log file. You should output similar to the following:

      2016-06-28T06:25:12.323-0600   main    INFO    com.ace.insight.data.service.dbinit.DbUpgradeService 0 Successfully transferred 21942 of 22101 node samples to MongoDB

      When the upgrade is completed, you will see the following lines in your /opt/insight/log/insight.log file:

      2016-06-28T06:25:13.120-0600	main	INFO	com.ace.insight.data.service.dbinit.DbUpgradeService 0 Database has been upgraded to current version
  3. On the Moab Server Host, have Moab resume sending messages to Insight. 
    mschedctl -r
