GT.M's unique functionality for creating logical dual site configurations of applications, has for years set the standard for continuity of business in the face of both unplanned as well as planned events. With V5.1-000, GT.M now provides for the creation of logical multi-site configurations of applications. As with prior versions of GT.M, updates originate with a primary instance (now referred to as the root primary instance). Whereas in prior versions of GT.M the primary instance replicated to a single secondary instance, in GT.M V5.1-000 the root primary can replicate to as many as 16 secondaries. Each of these secondaries can act as a propagating primary and replicate do as many as 16 tertiaries for a total of 273 instances. Each tertiary can replicate to 16 quarternaries for a total of 4,369 instances. And so on. In the event of a failure of the root primary instance, with appropriate network and operational procedures as discussed in the technical bulletin any other instance can become the new root primary. This provides for an unprecedented level of continuity of business.

Effective V5.1-000, a database file can be converted between little endian and big endian architectures. Options exist to convert database files in place, or while being copied. Previously, converting a database from one endianness to the other required an extract and load.

This functionality is described in the technical bulletin on Database Endian Conversion. The x86 and Alpha/AXP architectures are little endian. IBM eServer pSeries, Sun SPARC, and HP PA-RISC are big endian.

Following through on a previous announcement of Fidelity's intention to release the source code for GT.M on Alpha/AXP platforms, the source code for GT.M on HP Alpha/AXP Tru64 UNIX is being made available herewith.

Customers who are using the software under licenses other than the GNU General Public License (GPL) and who have purchased GT.M support from Fidelity Information Services can download GT.M from the FTP site. Please contact GT.M support for the current URL/password when you are ready to download the release. GT.M released under the GPL is available from Source Forge.

As an added precaution against errors in transmission and other causes of damage to the distribution files, checksums are available for each file. Please verify the checksums after downloading and before installing any GT.M distribution. If you get a checksum error, please download the file and try again. If you get the same incorrect checksum twice in a row, please send e-mail to gtmsupport@fnf.com as soon as possible.

Use "cksum <file>" to compute and print the checksum. Checksums are as follows:

• There is no difference in GT.M binaries released on Source Forge vs. the GT.M FTP site. However, since the software is released at Source Forge under the GNU General Public License, the package includes a COPYING file which changes the checksums. Note that source tarballs are available at Source Forge.

Please remember to download using binary FTP.
