How To Apply AppLogic Hotfixes

Some fixes (distro fixes) must be applied to the AppLogic image, from which AppLogic will then be installed and some should be applied to installed AppLogic.

1. Distro fix can be applied from ssh session on BFC by running the following command: <BFC_Install_Directory>/apply-version-hotfix –v <AppLogic_Version> -f <Download_Directory>/<Hot_Fix_Name>.

   For example this command:

   /opt/bfc/bin/apply-version-hotfix -v 3.1.14 -f /opt/bfc/downloads/applogic-3.1.14-df7725-part1.2.tar.bz2 applies hotfix df7725 to Applogic 3.1.14
   

   Name of <Download_Directory> can be found in BFC UI by clicking Administration link and then Versions tab in the right pane.

2. Other fixes can be applied from BFC UI as follows:
   1. Click Grids link and put a check mark next to the Applogic grid to which you need to apply the fix
   2. From Grid Actions select Apply Hotfix
   3. Window with available fixes should open – select fixes that you need to apply and click Apply Hotfix
   4. Once fixes are applied ssh to grid controller and type “3t grid info” and then type “3t server list" to see if any servers in the grid or entire grid require reboot after fix application
   5. If required type “3t grid reboot” (to reboot grid) or “3t server reboot <server_name>” (to reboot a single server).

If the fix that you need to apply is not in the list of fixes in step c above:

If fix is not in <Download_Directory> from step 1 on BFC, it must be downloaded to that directory (it may take 15-30 minutes after downloading to <Download_Directory> before fix shows up in BFC UI).

For the fix to be downloaded successfully from download.3tera.net and for it to be imported successfully, owner and group of distribution directories on BFC must be as follows:

 bfcadmin:bfc

for example ownership of 3.5.19 directory in /applogic_versions and in /opt/bfc/applogic_versions must be as follows:

drwxr-x---  7 bfcadmin bfc        4096 Oct 14 19:54 3.5.19    

If owner:group are different, change them by running this command: "chown -R bfcadmin:bfc 3.5.19"

If the ownership of the distribution directory is correct, fix will be downloaded to BFC from download.3tera.net automatically. If ownership is wrong, fix will not be downloaded. So after correcting ownership as described above, disable and then enable back automatic downloading in BFC UI - this will trigger the fix download.

Now, once fix is downloaded it can be imported to the grid by following steps below:

In BFC version 3.7:

• in BFC UI click on Versions link and in right pane expand the folder with the Applogic version to which you need to apply the fix
• you should see all available fixes that were not seen in step c above (such fixes will have blue icon)
• right click the needed fix and from dropdown select "Import" - wait till icon next to the fix turns green (that means import is completed)
• perform steps a - e from item 2 above

In BFC version before 3.7:

• in BFC UI click on Versions link and put check mark next to Applogic version to which you need to apply the fix
• click “+” symbol next to Version Actions – this should open New Version window
• in New Version window expand the folder next to the State of the version Name (by clicking little arrow symbol next to the folder icon)
• once the folder expands you should see all the available fixes that were not seen in step c above (such fixes will have blue icon)
• put check mark next to the fix and click Add
• perform steps a – e from item 2 above
