Notas de versão do Scalix 12.7

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 that proper 32 bit compatible libraries are installed.

Installation issues

1. 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. To allow connections in IP tables:
     

     • Open port 80 in iptables

     • restart the iptables service

     • restart the scalix-tomcat service

     • restart the httpd service

   • Initialize all web applications in Tomcat (this can take over 20 sec). If you make changes to Tomcat such as the above, please also restart apache (service httpd restart).

2. Debian installation sometime 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.

3. On IBM hardware platforms the installer does not install the jre package automatically. You would need to install JRE package manually.

4. 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.

5. While installing on a non ext4 filesystem, you might be presented with "Error in `omnewul': double free or corruption (top): To avoid this, it is recommended to use the ext4 filesystem
