Affected Products

  • TMG800, TMG3200, TMG7800-CTRL running Toolpack software older than rel2.7.176


Problem Description

Importing a database from a system running a newer major release to a older major release is not supported (e.g. import a database from a system running 2.9 to 2.7). Previous to release 2.7.176, there was no mechanism in the web portal to prevent such action. From 2.7.176 onward, the validation and recover now block such action. However, upgrading a system to a newer version which have a database imported from a newer major release system, will result in a failure of the upgrade.

How to get into the issue

  • Import a database backup from a newer major release to an older release previous to 2.7.176. e.g. Import a database backup from rel2.9 to a TMG which is running rel2.7.175 (or older)
  • Validate/Recover the database backup (validation and recover would be performed)

System database backup recover

Each time a database backup is recovered, the system proceed to the following actions:

  • perform an automatic backup of the actual database (under Backups->Automatic database backups)
  • erase the actual database and replace it by the new database (recovered)
  • proceed to the database data upgrade to match the actual system's version

How to validate your system database

Release Database Name Unique data upgrade number
Release 2.6 toolpack_0 3
Release 2.7 toolpack_0 15
Release 2.8 toolpack_2_8 44
Release 2.9 toolpack_2_9 57
# mysql -u tbdb -ptbdbpw -e "select * from database_name.current_data_upgrades order by CAST(id as SIGNED INTEGER) asc;"

To make sure your system does not run with a newer version database, you can look at the database data upgrades table and make sure that is does not include upgrades from newer releases. Note that some upgrade number are common to more than one release, for example the upgrade number '61', '63', '73', etc.. are common to both 2.8 and 2.9 releases. The table above provides unique data upgrade for a particular major release. For example, the data upgrade '57' can only be found if the database data have been upgraded from a 2.9 system.

For, example, if your system runs release 2.8, in the command above replace database_name by "toolpack_2_8" to get the list of upgrades performed on your database:

 # mysql -u tbdb -ptbdbpw -e "select * from toolpack_2_8.current_data_upgrades order by CAST(id as SIGNED INTEGER) asc;"
 [root@TB013496 ~]# mysql -u tbdb -ptbdbpw -e "select * from toolpack_2_8.current_data_upgrades order by CAST(id as SIGNED INTEGER) asc;"

In the example above, you can find the data upgrade number '44' in the list, which indicate that the data of this database have been upgraded by a 2.8 system. However, the data upgrade number '57' is not present, which meant that it was not upgrade by a 2.9 system. therefore, this is a valid database for a 2.8 system.

If you find out data upgrades from a newer releases, you should:

  1. Recover from a valid database backup of a previous or similar release. The backup could also be imported from another system.
  2. Since there is no conversion tools to migrate the data from a newer release database to an older release, you might have to manually reconfigure some items in your system (missing parts that was configured on your newer release database or that you have configured since you imported the newer release database on your system)

Problem Symptoms

If your database data have been previously upgraded by a newer release, performing a major upgrade on your system would lead to a failure of the software release upgrade.

  • Software release upgrade fails, always switch back to the old version
  • tboamapp logs would shows
database_upgrade: [FAIL]    ERROR: data upgrade 26 failed: ERROR: data upgrade 26 and your system would not switch to the latest 

Solution

If your database was previously upgraded from a newer release (as described above) and you inadvertently upgraded your system to a newer software release which ended by a failure, you must recover your database with one from the release your were running previous to the upgrade. You can look for an automatic backup in Backups (web portal) and recover from it.

For example, lets say your database was recovered from a 2.9 system on a 2.7 system and you upgraded to the software release 2.8. After you activated the package 2.8, the system would report a failure and fall back on 2.7 (if running 2.7.148 onward). Here is the steps you should follow:


1. Recover from a valid 2.7 database backup or a previous release backup. Skip to steps 4a or 4b.


If for some reason you can't recover a valid database, erase the databases to force the system to create new ones:


2. ssh to your TMG host


3. Drop the 2.7 database (toolpack_0) and the 2.8 database (toolpack_2_8):

 # tbtoolpack stop
 # mysql -u tbdb -ptbdbpw -e "drop database toolpack_0;"
 # mysql -u tbdb -ptbdbpw -e "drop database toolpack_2_8;"


4a. If you upgrade from a release previous to 2.7.148, you must follow the instruction below:

# tbtoolpack stop

Edit the following file with "vi":

 vi /lib/tb/toolpack/setup/12358/service/config.txt

Make sure that the 'application=' line contain '2.8'.

 application= /lib/tb/toolpack/setup/12358/2.8/apps/tboamapp/tboamapp_wd_cfg.ini

Restart toolpack

 # tbtoolpack start


4b. If you upgrade from a release supporting major release upgrade from the web (2.7.148 and above), you must follow the instruction below:

Restart toolpack

 # tbtoolpack start

From the Web portal, activate package 2.8.
