Disclaimer

  • The test appliance should not be used in production for this reasons (would need to reconfigure Scalix with different domain/password) before you can start the download.
  • Scalix Connector needs to be installed with proper Admin-rights on your Computer
  • System needs to be backed up before upgrade.

 

Java Environment

Be aware that some middleware components of Scalix require JRE. We support JRE >=1.6 and <=1.8, vendors: Oracle, IBM, opensource (openjdk in particular)

Please note that :

  • We do not recommend using openjdk on production systems because it can cause slowdowns, higher CPU/Memory usage and can cause instability and unexpected errors. While you can install Scalix 12.6 with the openjdk we suggest that you use the openjdk with systems that are non-production, testing system or low load servers.
  • For IBM platforms you would need to install the IBM JRE package manually.

Scalix Binaries

All the Scalix server binaries are compiled as 32-bit only for the moment.

Scalix can be installed on 64-bit Intel or IBM computers, and in 64-bit Linux environments as a 32-bit application. You will need to make sure, proper 32 bit compatible libraries are installed.

Installation issues

  • The following procedure/adjustments are mandatory if you installed CentOS6 (64bit) or ORACLE Linux 6 (x86/x64)
    • If port 80 is not set to allow connections (open) in ip tables, Tomcat will not work at all - scalix-tomcat service will run, but in the tomcat log there will be a big backtrace
      • Open port 80 in iptables
      • restart the iptables service
      • restart the scalix-tomcat service
      • restart the httpd service
    • After this it should be working correctly
    • Secondly initialization of all web applications in Tomcat can take over 20 sec - Tomcat will work only after initialization of its webapps. If you make changes to Tomcat such as the above, please also restart apache (service httpd restart).
  • On Debian sometime installation fails due to a pre-existing error in the sendmail.cf file with the MAILER lines in the wrong place. To fix this manually move the bad MAILER lines to the end of the file and try again.
  • On IBM hardware platforms the installer does not install the jre package automatically. You would need to install JRE package manually.
  • To improve SWA performance you must follow description from official Apache website and make changes accordingly depending on your environment and jre that you are using.
  • While installing on a non ext4 filesystem, you might be presented with error “Error in `omnewul': double free or corruption (top): 0xxxxxxx” To avoid this, it is recommended to use ext4 filesystem

 

Important end of Life Notices

•         Upgrading from Scalix 11.3 or earlier is not supported

 

Upgrade Notices

Please read the following notes very carefully, as some specific actions might be required as you upgrade from earlier versions of Scalix.

When running Scalix in a mixed-version multi-server setup, where your front end servers are running Scalix Web Access 12.6, the back end servers have to be upgraded to at minimum version 12.6 as well.

Upgrading from a previous version

If you are upgrading from a previous version of Scalix, there are several changes of which you should be aware:

  • Before beginning any upgrades, check your license key. If you are upgrading to or from a Small Business Edition (SBE), Enterprise Edition (EE) or Hosting Edition (HE) installation, you need to have a valid and current license key with a "Last Valid Issue Date" (LVID) on or after July 1, 2016 (2016-07-01) to use Scalix 12.6. If you continue installation after the respective warning and the license is not valid, your installation will downgrade to the Community Edition. To check the LVID of your license, use the Scalix Management Console or the sxlicense command. To extend your upgrade subscription or to get a new license key, please contact Scalix Sales.
  • When upgrading from previous installation of Scalix to 12.6, it is recommended that you empty your IMAP caches by running the following command on your backend server. Please note that this command may only be run when nobody is signed on to the system (when the rci and IMAP services are off): cd $(omrealpath "~/"); find user* -name imap-cache -exec rm -rf {} \;
  • While moving Scalix to a newer OS version, please follow http://www.scalix.com/wiki/index.php?title=Howtos/Move_Scalix

Alert

Note that the choice of storage environments will have a major influence on performance of your Scalix system. Scalix as an application is largely I/O-bound, using variable, small-blocksize random read/write synchronous file I/O.

Also note that Scalix does not support putting a Scalix Message Store on a NFS- or SMB-based storage device such as a NAS Filer. Performance issues and/or Message Store corruption can occur. This is true for all Linux distributions using Linux 2.6.x kernels as the NFS client software in these kernels have known issues with file locking operations, which Scalix heavily relies on.

We suggest putting the Scalix message store on a Hardware RAID Array, using RAID 1+0 for best performance. The use of RAID 5 or RAID 6 will result in substantially worse performance due to the nature of Scalix Disk I/O patterns (small, synchronous random writes) and is not recommended. In larger installations, we do recommend using iSCSI- or FibreChannel-based SAN storage. We also recommend the use of battery-backed write cache on the RAID controller where available
