Installing and Removing Hotfixes

Hotfixes are small correction packages that may include software for one or more server packages, or a client workstation component.

Installing Hotfixes on Servers

Install the hotfix package with the Infrastructure Administrator (IA).

  1. Extract the files from the hotfix package to the ...\Install\hotfixes subdirectory of the installation directory of your Sinch Contact Pro system. Check which software packages are included in the hotfix.

  2. Start IA and run it in Monitoring Mode, and inactivate the virtual unit(s) where the affected software package(s) are located.

    Note:

    If the IA is already running, choose Deployment > Refresh Local System so that IA detects the newly added hotfixes from the ...\Install\hotfixes subdirectory.

  3. Set Infrastructure Administrator to Deployment Mode

  4. Add the right hotfix to the right base installation:

    • Choose Deployment > Add Hotfixes To Base Installation.

    • Choose the base installation (the right support package) from the list.

    • Choose the hotfix you are installing from the list. If the hotfix is not in the list, you have extracted the files to another folder, you can browse it with the … button.

    • Choose OK.

  5. To refresh the host and all nodes:

    • Choose Deployment > Refresh Local System.

    • Right-click the HAC Nodes and choose Refresh All Nodes.

  6. Add the hotfix to the right software package:

    • Choose the virtual unit where the software package to be updated is located.

    • Right-click the actual component under the Software, and choose Add Hotfixes.

    • Choose this hotfix.

    • Choose OK.

  7. If the hotfix includes corrections to more than one software package, repeat the previous step on the virtual unit where the other packages are installed.

  8. Right-click Virtual Units in the tree and choose Synchronize Instances. This advances new changes to all HAC nodes where the changed software package has instances.

  9. To commit the changes, choose either Deployment > Apply Changes to Host (or Apply Changes to Local System) per every HAC node, or right-click the HAC Nodes in the model tree and choose Apply All Changes to All Hosts.

  10. Set IA to Monitoring Mode.

  11. Activate the virtual unit(s).

  12. Save the system model.

Installing MSI Packages on Client Workstations

Check if the hotfix includes client workstation components that are delivered as MSI packages. If there are MSI packages, replace the previous components with them on all client workstations.

  • Remove the previous version with the Control Panel option Remove software.

  • To install the new version, double-click the corresponding MSI package.

You can also use group policies or other methods to apply changes to several client workstations simultaneously.

For more information, see Client Workstation Guide.

Removing Hotfixes

Note:

To remove a hotfix, remove it first from the software package, and then from the base installation. Make sure you perform both steps when appropriate.

  1. Start Infrastructure Administrator (IA).

  2. To change the system to the deployment mode, choose Connection > Deployment Mode.

  3. Inactivate the virtual unit(s) where the hotfix has been installed.

  4. Remove the hotfix from the software package:

    1. Choose the virtual unit where the software package is located.

    2. Right-click the software package under Software, and choose Delete Hotfix.

    3. Choose the right hotfix and OK.

  5. Right-click Virtual Units in the tree and choose Synchronize Instances. This advances new changes to all HAC nodes where the changed software package has instances.

  6. Repeat the steps 4 and 5 on all virtual units where the package has been installed.

  7. Remove the hotfix from the base installation:

    1. Choose Deployment > Remove Hotfixes from Base Installation.

    2. Choose the base installation from the selection list.

    3. Choose this hotfix package from the selection list.

    4. Choose OK.

  8. To commit the changes, choose either Deployment > Apply Changes To Host per every HAC node, or right-click HAC Nodes in the model tree and choose the option Apply All Changes To All Hosts.

  9. Activate the virtual unit(s) you inactivated in step 3 and restore the Monitoring Mode.
