Before you begin
Chapter 2. Installing GT.M

Read the GT.M Release Notes documentation. The release documents contain the latest information that may be critical for installing and configuring GT.M. They are located at the User Documentation tab on the GT.M website (www.fis-gtm.com).

Determine whether or not, GT.M access is restricted to a group. Keep the group name handy as you will have to enter it during the installation process.

Set the environment variable gtm_log to a directory where GT.M should create log files. In conformance with the Filesystem Hierarchy Standard, FIS recommends /var/log/fis-gtm/$gtmver as the value for $gtm_log unless you are installing the same version of GT.M in multiple directories. Note that $gtmver can be in the form of V6.1-000_x86 which represents the current GT.M release and platform information.

If you do not set gtm_log, GT.M creates log files in a directory in /tmp (AIX, GNU/Linux). However, this is not recommended because it makes GT.M log files vulnerable to the retention policy of a temporary directory.

	Important
	Starting with V6.0-000, gtmsecshr logs its messages in the system log and the environment variable gtm_log is ignored.

If you need to perform UTF-8 mode operations in GT.M, you must have at least ICU version 3.6 installed. GT.M uses ICU 3.6 (or above) to provide the support for UTF-8 mode. GT.M generates the distribution for UTF-8 mode only if ICU 3.6 (or above) is installed on your system. By default, GT.M uses the most current version of ICU. GT.M expects ICU to have been built with symbol renaming disabled and issues an error at startup if the currently installed version of ICU has been built with symbol renaming enabled. If you intend to use a version of ICU built with symbol renaming enabled or any version other than the default, keep the MAJOR VERSION and MINOR VERSION numbers ready as you will have to enter it as MajorVersion.MinorVersion (for example "3.6" to denote ICU-3.6) during the installation process.
