32-bit and 64-bit requirements for your OS
The installation includes both 32-bit and 64-bit libraries, to support 32-bit and 64-bit applications. You must install the 64-bit BMC Remedy AR System server on a compatible 64-bit operating-system platform.
For Windows and UNIX, arserverd is the only 64-bit binary. The others are 32-bit. Therefore, other binaries might have dependencies on some 32-bit operating-system libraries.
For the most up-to-date information about 64-bit BMC Remedy AR System server compatibility with specific operating systems and versions, see Checking system requirements and supported configurations.
64-bit servers must run with 64-bit database clients.
Installing BMC Remedy AR System 64-bit servers
The database for a 64-bit BMC Remedy AR System server must use 64-bit database client libraries. Before installing a 64-bit version of BMC Remedy AR System 8.0.00, ensure that the 64-bit database client libraries are installed on the computer that runs the BMC Remedy AR System server (arserver.exe).
Although the 64-bit server can use a 64-bit address space, it stores 32-bit values in the database and exchanges 32-bit values with API clients. It does not store 64-bit values in the database.
When a 64-bit AR System server is installed, all its 64-bit dependent libraries are installed in a separate lib64 directory within the AR System server installation directory, except for the arserver.exe file, which is installed directly in the AR System server installation directory. The existing BMC Remedy AR System sever installation directory contains all the 32-bit libraries and other platform processes. The installer sets the <install directory> and <install directory\>lib64 path variable.
On the HP Itanium platform (HPIA-64), HP-PA plug-in applications must be configured to run on the C-based plug-in server. On the other 64-bit platforms, plug-in applications can run on either the C-based or the Java-based plug-in server.
The BMC Remedy AR System Java-based applications, such as BMC Remedy Mid Tier, Email Engine, Developer Studio, and Flashboards server, are already compiled as 32-bit for all platforms and require that you use a 32-bit JVM on a 32-bit operating system.
The BMC Remedy AR System Oracle Java-based applications are compiled as 64-bit for all platforms and require that you install a 32-bit or 64-bit JVM.
The Java plug-in server and full-text search (FTS) also support a 64-bit JVM. During installation, you have the option of installing the Java plug-in server on either a 32-bit or 64-bit JVM. According to this selection, the FTS is installed. For example, if you choose to install the Java plug-in server on a 32-bit JVM, FTS is also installed on a 32-bit JVM. Similarly, if you choose to install the Java plug-in server on a 64-bit JVM, FTS is installed on a 64-bit JVM.
Following are the exceptions for the 64-bit JVM support:
- BMC Remedy Email Engine — The MAPI protocol is disabled for a 64-bit JVM; requires 32-bit JVM if using the MAPI protocol
- BMC Remedy Mid Tier — Requires the 32-bit JVM if the web server is 32-bit or is running in 32-bit mode
You can specify these exceptions in the installer if necessary for your installation.
To use the MAPI protocol for BMC Remedy Email Engine, you can install and use a 32-bit JVM on a 64-bit computer.
