This document provides instructions for updating Sun Microsystems Java Runtime Environment (JRE). An update of the JRE should only be performed if corporate policy prevents you from using a JRE without the most recent security updates. Regular updates of the JRE are not required and do not affect the stability or performance of SQL Anywhere.
A copy of the JRE is included with SQL Anywhere for Microsoft Windows, Linux, and Solaris operating systems. The SQL Anywhere administration tools, including Interactive SQL, Sybase Central, MobiLink Monitor, and DBConsole, use the JRE. In addition, MobiLink and the database server use the JRE for the Java external environment. The most recent version of the JRE is included with the SQL Anywhere general availability (GA) release. If the JRE is updated after the GA release and it affects the functionality of the SQL Anywhere application, an updated JRE is provided in an express bug fix (EBF). Security improvements made to the JRE that do not affect the functionality of SQL Anywhere are not provided.
Although updating the JRE should not affect the functionality of SQL Anywhere, the update might cause unexpected results. Report all issues to Sybase iAnywhere. Updating the JRE installed with SQL Anywhere should not affect other Java software running on the computer. The administration tools use the JRE included with SQL Anywhere and are unaffected by any other JRE that is installed on the same computer.
