Instead, they would be upgraded as release-independent versions. Bug fixes, new features, and updates to components of server software are now included in these versions rather than released in individual patches.  For example, a service provider running BroadWorks Release 21sp1 may wish to upgrade to R22. But in order to update its Media Servers, it would install and activate the release-independent version Rel\_2018.12\_1.120, or the most recently released version, instead. There is no possibility of upgrading to Release 22, nor are any patches issued as with the other BroadWorks non-resource servers. Furthermore, it's not even necessary to upgrade the rest of the platform to R22, since these release-independent versions are backward compatible. So a Media Server running Rel\_2018.12\_1.120 can function perfectly with the R21sp1 platform. The following resource servers now following this upgrade pattern: - MS – Media Server - SCF – Service Control Function Server - UVS – BroadWorks Collaborate Video Server - USS – UC-One Sharing Server - WRS – WebRTC Server How does one perform an upgrade to these resource servers? The experience is similar to a release build upgrade, but with some key differences. The following example of upgrading a WRS will demonstrate the process. ## 1. Download the base installation binary and preInstallCheck from BroadSoft Xchange. Download the Software Manager as well if a newer version has been released than the one currently running on the server.  Verify the checksums of these binaries, and set their permissions to execute. `[root@wrs1 install]# md5sum WRS_Rel_2018.12_1.120.Linux-x86_64.bin fe55d67e8130ccbb4481dd0134e41957  WRS_Rel_2018.12_1.120.Linux-x86_64.bin` `[root@wrs1 install]# chmod 755 bw-preInstallCheck-Rel_2018-731835.bin` ## 2. As root, run the preInstallCheck, in order to look for any issues that must be addressed prior to upgrade. The release-independent preInstallCheck binaries for resource servers are specific to that version, and are different from those issued for release builds of non-resource servers, so take care to use the correct one. `[root@wrs1 install]# ./bw-preInstallCheck-Rel_2018-731835.bin` `==============================================================  = BroadWorks Pre-Install Check Script --- Version: 1.9  ============================================================== ` In this example, /etc/hosts.allow and /etc/hosts.deny had to be modified before installation of the new WRS version. This particular issue is usually covered by post-patching instructions on non-resource servers. Here, the upgrade would probably fail if these instructions were not followed before upgrading. `###############################################################################                                  RESULTS ` `Pre-Install check validation FAILED ` `The following error(s) MUST be fixed prior to perform upgrade:  FAIL=>stunnel configuration issue in /etc/hosts.allow:` `                                - May not be allowed` `                                - Potential security hole  SOLUTION=>Add the following lines to /etc/hosts.allow: ALL EXCEPT stunnel: ALL stunnel: localhost  FAIL=>stunnel configuration issue in /etc/hosts.deny:` `                                - Potential security hole  SOLUTION=>Add the following line to /etc/hosts.deny: stunnel: ALL ` `###############################################################################` After correcting any problems, run the preInstallCheck again. `###############################################################################                                  RESULTS ` `Pre-Install check validation SUCCESSFUL ` `NOTE: Upgrade will be allowed to the following destination releases:  2017 2018 2019` `NOTE: Don't forget to install the latest SWManager ` `###############################################################################` ## 3. Execute the installation binary. Note that, unlike with release build installations, there is no "-patch" tarball to be specified – just the base installation binary. `[root@wrs1 install]# ./WRS_Rel_2018.12_1.120.Linux-x86_64.bin` `==> BroadWorks installation <== WRS_Rel_2018.12_1.120` The installation will run non-interactively and show its results. `==============================================================             The installation is now completed.  ==============================================================` Read and follow any post-installation instructions created by the installation process. ## 4. Activate the new version. This is the same procedure as with servers being upgraded to a new release of BroadWorks. `WRS_CLI/Maintenance/ManagedObjects> lock` `WRS_CLI/Maintenance/ManagedObjects> set activeSoftwareVersion server WRS 2018.12_1.120` `WRS_CLI/Maintenance/ManagedObjects> unlock` Installation and activation are now complete. ## 5. Confirm that the resource server is running the new version. `bwadmin@wrs1$ bwshowver WRS version Rel_2018.12_1.120` `Built  Sat Dec  8 01:28:10 EST 2018 - BASE revision 769570 - WRS revision 769900` ## Similar posts [![BroadSoft BroadWorks Database Server (DBS) - Cheat Sheet](https://www.ecg.co/hubfs/ecg-site/blog-listing-placeholder.jpg)](https://www.ecg.co/blog/111-broadsoft-broadworks-database-server-dbs-cheat-sheet) ### [BroadSoft BroadWorks Database Server (DBS) - Cheat Sheet](https://www.ecg.co/blog/111-broadsoft-broadworks-database-server-dbs-cheat-sheet) [![Cisco-BroadSoft Pushes BroadWorks Operators Toward Better Patching](https://www.ecg.co/hubfs/Imported_Blog_Media/regular_0013AD1A-740F-429F-98B9-0897073DCBF1-1.png)](https://www.ecg.co/blog/136-cisco-broadsoft-pushes-broadworks-operators-toward-better-patching) ### [Cisco-BroadSoft Pushes BroadWorks Operators Toward Better Patching](https://www.ecg.co/blog/136-cisco-broadsoft-pushes-broadworks-operators-toward-better-patching) [![New Discussion Group](https://www.ecg.co/hubfs/ecg-site/blog-listing-placeholder.jpg)](https://www.ecg.co/blog/34-new-discussion-group) ### [New Discussion Group](https://www.ecg.co/blog/34-new-discussion-group) ## Need Help With Your Network or AI Project?
