Introduction

SOS provides JS7 - Patches in a situation of severe bugs or Vulnerabilities.

• Bugs, vulnerabilities and patches are communicated with the SOS Change Management System.
• Find below the information how to apply patches to JOC Cockpit.

Apply Patch to JOC Cockpit On Premises

JOC Cockpit expects Java .jar libraries for patches from the following location:

• Unix
  • /var/sos-berlin.com/js7/joc/jetty_base/webapps/joc/WEB-INF/classes
• Windows
  • C:\ProgramData\sos-berlin.com\js7\joc\jetty_base\webapps\joc\WEB-INF\classes

The JETTY_BASE part of the above path is specified during installation and can point to a different location. The remaining part webapps/joc/WEB-INF/classes is the same for any installation.

Apply Patch

Apply the following steps to a JOC Cockpit instance. If a JOC Cockpit cluster is operated then steps are performed for any JOC Cockpit instance.

# navigate to the target directory for patches
cd /var/sos-berlin.com/js7/joc/jetty_base/webapps/joc/WEB-INF/classes

# verify the directory by checking if this file is available
ls api-schema-version.json

# download the patch archive
curl https://download.sos-berlin.com/patches/patch-20220309-JOC-1256-2.2.2_2.2.3.jar -O

# extract the patch archive (use "jar" or "unzip" command)
jar -xf patch-20220309-JOC-1256-2.2.2_2.2.3.jar
# remove the patch archive
rm patch-20220309-JOC-1256-2.2.2_2.2.3.jar

@rem navigate to the target directory for patches
cd %ProgramData%\sos-berlin.com\js7\joc\jetty_base\webapps\joc\WEB-INF\classes

@rem verify the directory by checking if this file is available
dir api-schema-version.json

@rem download from URL https://download.sos-berlin.com/patches/patch-20220309-JOC-1256-2.2.2_2.2.3.jar
@rem copy from download location (could be different from this example)
copy %USERPROFILE%\Downloads\patch-20220309-JOC-1256-2.2.2_2.2.3.jar .

@rem extract the patch archive (use "jar" or "unzip" command)
jar -xf patch-20220309-JOC-1256-2.2.2_2.2.3.jar
@rem remove the patch archive
del patch-20220309-JOC-1256-2.2.2_2.2.3.jar

This example uses the jar command that is available from a Java JDK. Should no Java JDK be in place then the unzip command can be used.

The resulting directory hierarchy should look like this (with the com sub-directory being created from the extracted patch):

• webapps/joc/WEB-INF/classes
  • com
    • sos
      • ...

Note: A restart of JOC Cockpit is required to apply patches.

Note: As an alternative for Windows you can download the .jar patch file to the target directory and use tools such as 7-Zip to extract the archive. Do not create a sub-folder from the archive name but extract directly to the directory hierarchy as indicated above.

Remove Patch

Patches are automatically removed when a JOC Cockpit release is installed.

Patches can be manually removed by dropping the com sub-directory that holds the extracted patch.

Note: A restart of JOC Cockpit is required to apply removal of patches.

Apply Patch to JOC Cockpit Docker® Containers

JOC Cockpit expects Java .jar libraries for patches from the following location:

• /var/sos-berlin.com/js7/joc/jetty_base/resources/joc/patches
• The directory /var/sos-berlin.com/js7/joc/jetty_base/resources/joc typically is mounted to a Docker config volume when running the container: for details see JS7 - JOC Cockpit Installation for Docker Containers. The patches sub-directory should be created if it does not already exist before storing the patch file to this location.

Apply Patch

On startup the JOC Cockpit container checks the above directory for existence of *.jar files. If a file is found then

• the file will be extracted to /var/sos-berlin.com/js7/joc/jetty_base/webapps/joc/WEB-INF/classes
• for details see chapter On Premises.

Patches are applied on start-up of a container. Therefore patch files remain in place in the /var/sos-berlin.com/js7/joc/jetty_base/resources/joc/patches sub-directory (typically mounted to the config/patches volume directory) as long as the patch should be applied.

Note: A restart of the JOC Cockpit container is required to apply patches.

Remove Patch

Patch files are removed by dropping the files in the patches sub-directory.

Note: A restart of the JOC Cockpit container is required to apply removal of patches.
