Upgrade TACTIC

Upgrading TACTIC version is a simple precedure and generally involves the following steps,

  1. Stop the TACTIC service
  2. Backup the database
  3. Update source code
  4. Run upgrade_db.py
  5. Restart the TACTIC service

Linux Upgrade

  1. Download the new release of TACTIC from the Download section of support.southpawtech.com . TACTIC is delivered as a zipped (.zip) file.

  2. Copy the new version to the installed directory of TACTIC and unpack it. e.g.

    cd /home/apache/

    unzip tactic-2.6.0.v01.zip

  3. Stop the TACTIC service

    /etc/init.d/tactic stop

  4. Switch the symbolic link. See explanation on symbolic link below.

  5. In a cmd shell, cd to the bin directory of the new installation:

    cd /home/apache/tactic/src/bin

  6. Back up the current database:

    pg_dumpall -U postgres -c > database_<date>.sql

  7. Run the upgrade script. The version number argument (for example, 2.6.0.v01) is optional.

    python3 upgrade_db.py

    First, you will be prompted to confirm whether the displayed version is the right one to upgrade to.

    On proceeding, it will check the upgrade script’s version tree against the currently installed TACTIC version (the new one).

    Normally, they should be the same. In case they are not, you will be prompted again to confirm if this is actually intended.

    Warning: If the versions do not match, it is very likely you have not stopped the old version from running or have not symlinked "tactic" to the new version yet.

  8. Restart the TACTIC service:

    /etc/init.d/tactic start

  9. Go to the "Projects" view in the Admin site.

  10. Optional: Compare each project’s schema with the one used by TACTIC.

Explanation of switching symbolic links

By default, in your python installation, like

/usr/lib/python2.5/site-packages/tacticenv/tactic\_paths.py

it defines,

TACTIC\_INSTALL\_DIR = '/home/apache/tactic'

A convenient way to upgrade is to untar the new release in, 

/home/apache/tactic-2.5.0.rc04

then delete any existing symbolic link named "tactic",

cd /home/apache 
rm tactic

Afterwards, you can create a new symlink using 

ln -s tactic-2.5.0.rc04 tactic

With the tactic service stopped, and the TACTIC_INSTALL_DIR practically pointing to the new release because of the symlink, now you can safely run

python3 src/bin/upgrade\_db.py

in the new release.

Windows Upgrade

  1. Download the new release of TACTIC from the Download section of support.southpawtech.com . TACTIC is delivered as a zipped (.zip) file.

  2. Copy the new version to the installed directory of TACTIC and unzip it.

  3. Stop the TACTIC service from the services panel.

  4. Rename the top directory of the new version to TACTIC.

  5. In a cmd shell, cd to the bin directory of the new installation:

    cd C:\Program Files\Southpaw\Tactic\src\bin

  6. Back up the current database:

    pg_dumpall -U postgres -c > database_<date>.sql

  7. Run the upgrade script. The version number argument (for example, 2.6.0.v01) is optional.

    python3 upgrade_db.py

    First, you will be prompted to confirm whether the displayed version is the right one to upgrade to.

    On proceeding, it will check the upgrade script’s version tree against the currently installed TACTIC version (the new one).

  10. Optional: Compare each project’s schema with the one used by TACTIC.
