The binary packages are designed for easy installation. Each platform uses its native installation format (RPM for Linux, pkg for Solaris). All installations have identical installation paths, so no path translations are required in this section.

The supported platforms are as follows:

  • Red Hat Enterprise Linux 5 (x86_64)

  • Red Hat Enterprise Linux 5 (i386)

  • Red Hat Enterprise Linux 6 (x86_64) (As of version 3.4.)

  • Solaris 10 (amd64)

  • Solaris 10 (sparcv9)


Message Systems only supports 64-bit environments for Momentum 3.6.x and later.


Please unset the following environmental variables before installing or upgrading:

  • unset LC_MONETARY

  • unset LC_NUMERIC

  • unset LC_MESSAGES

  • unset LC_COLLATE

  • unset LC_CTYPE

  • unset LC_TIME

The variables are sometimes set by your terminal program, by iTerm for Mac OS X, for example. Also, make sure that the following variable is set:


This is especially important for upgrades from 3.2.x to 3.3.x.

The expected installation path is /opt/msys/ecelerity: If you choose to move this installation to a different final location we recommend soft linking /opt/msys/ecelerity to that location.

If you are upgrading to Momentum version 3.3, be sure to review “PostgreSQL in Momentum Version 3.3”.

Supported Versions in Momentum 3.5.4

  • Red Hat 5.9 (and its CentOS equivalent) on both i386 and x86-64 architectures

  • Red Hat 6.4 (and its CentOS equivalent) on x86-64 architecture

  • Solaris variants: Solaris 10 (minimum level U3) on both SPARC and AMD64 architectures

  • Note that Momentum 3.5 and future releases are not supported on Red Hat 4. Red Hat dropped support for this release in February 2012.
