32-bit and 64-bit requirements for an upgrade

The BMC Remedy AR System server binary for Windows can be installed as a native 64-bit executable on 64-bit operating-system platforms. The Oracle Solaris, HP-UX (Itanium), and IBM AIX servers continue to be 64-bit releases.

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.

64-bit database client libraries

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, make sure that the 64-bit database client libraries are installed on the computer that will run the BMC Remedy AR System server (arserver.exe).


Although the 64-bit server can make use of 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 <installDirectory> and <installDirectory\>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.

Java requirement

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 Java-based applications are compiled as 64-bit for all platforms and require that you install a 32-bit or 64-bit JVM.

The following are the exceptions for the 64-bit JVM support:

  • BMC Remedy Email Engine — The MAPI protocol is disabled for 64-bit JVM. Requires 32-bit JVM if using the MAPI protocol.

You can specify these exceptions in the installer if required 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.
