UNIX and Linux Installer Issues

Installing on Linux

On Linux, the 32-bit version of Java is required to install and use Visual COBOL for Eclipse. When you start the installation, if the 64-bit version of Java is already installed on your Linux machine, you might not be able to install Visual COBOL. This is a known issue with the Oracle Java installers for Linux which prevent you from installing both the 32-bit and the 64-bit versions of Java on the same machine. To work around this problem:

• Download the 32-bit Java distribution in a compressed .tar format from the Oracle Web site.
• Untar the distribution into a location different from the one used for the 64-bit Java version. For example, untar in /usr/local/java32 and not in /usr/local/java.
• Set JAVA_HOME and LD_LIBRARY_PATH to the 32-bit version of Java so that it is used to install and run Visual COBOL.

License Server

You need to configure the computer hostname to ensure the license server will start properly.

To avoid performance issues, "localhost" and the computer hostname must not both be mapped to IP address 127.0.0.1. You should only map "localhost" to IP address 127.0.0.1.

The following is an example of how to specify these entries correctly in the etc/hosts file:

127.0.0.1 localhost.localdomain localhost
IP machinelonghostname machineshorthostname

where IP is the unique IP address of the computer in xx.xx.xx.xx format.
