Sybase recommends that the $SYBASE directory on Solaris and the %SYBASE% directory on Windows is the same on each machine. Delete the vpd.properties file in your home directory before starting the installation on the next machine.
If you plan to use Adaptive Server Enterprise instead of the ASA included with the EP installation, you must install it and create the required tables on ASE prior to installing EP. See Table 2-3 for information about creating the required tables.
If you are using the Apache Web Server configured with the EAServer redirector for load balancing, a minimum of three machines running EAServer and one running the Apache Web Server is required.
If you are using a hardware or third-party software redirector, verify that it supports sticky sessions and note any references to optimal load distribution requirements.
EAServer redirector – the EAServer redirector is optimized for request distribution across odd numbers of machines. In order to ensure equal request distribution, odd numbers of EAServer instances are recommended, for example, 3, 5, 7, and so on.
The EAServer redirector is not included on the EP installation
CD. You can obtain the redirector from your EAServer installation
CD, or from an existing full installation of EAServer. See the EAServer
System Administration Guide for information about setting up the
redirector to work with the Apache Web Server.
If you are using the Apache Web Server with the EAServer redirector, Apache must be installed on its own machine as EP and Apache listen on the same ports.
When a Web server is redirecting to an EAServer on a different machine, all URLs in the global.properties.xml file (except for the EAServer IIOP URL) must indicate the Web server host name, not the EAServer machine host name.
All EAServers must have a localhost.domain.name HTTP listener defined.
All three HTTP listeners (EAServer local host, EAServer network-accessible, and Web server) must use the same port number.
