Re: GT.M V5.3-004 released

It looks like the posting broke the URLs to the documents. Simply go
to the GT.M home page (http://fis-gtm.com) and click on the User
Documentation tab to get to a page from which all user documentation
is accessible.

GT.M V5.3-004 adds major new functionality and platform support.

    * Support for z/OS on the IBM eServer zSeries computing platform.
GT.M programs now run on mainframes using the zFS file system with a
high degree of portability from and to other POSIX environments.
Details are in the GT.M on IBM eServer zSeries z/OS Technical Bulletin
(http://fidelityinfoservices.com/user_documentation/html/rn_tb/
GT_M_on_z_OS_Technical.html).

    * Database encryption.  GT.M on selected platforms can encrypt
data in database and journal files.  Encryption protects against
unauthorized access to data by an unauthorized process which is able
to access disk files, that is, encryption protects data at rest (DAR)
to help improve security in cloud based application deployment, as
well as making it easier for sites to comply with data protection
standards such as PCI and HIPAA.  A plug-in architecture facilitates
use of your preferred encryption software.  Details are in the GT.M
Database Encryption Technical Bulletin (http://www.fidelityinfoservices.com/FNFIS/Markets/NonFinancialIndustries/Hea...).

    * Alias variables.  Intended to provide an underlying technology
for implementing an object layer, alias variables provide a layer of
abstraction between the name of a local variable and an array
analogous to that provided by M pass by reference in subroutine
invocations.  Multiple local variables can be aliases, and a SET or
KILL to one acts as a SET or KILL to all.  Alias container variables
provide a way of storing a reference to a data-space in an M sparse
array, which protects the associated array even when it’s not
accessible through any current name.  Details are in the GT.M Alias
Variables Technical Bulletin (http://www.fidelityinfoservices.com/
user_documentation/html/rn_tb/GT_M_Alias_Variables_Te.html).

On UNIX/Linux platforms, the database file size limit has been
increased from 128M to 224M blocks.  So using the popular 8KB block
size, the largest database file that can be created is 1,792GB.  Of
course, since a complete database can consist of an arbitrary number
database files, the size of a complete database can be truly enormous.

There are performance enhancements, among others, especially for
applications that use Transaction Processing.  Compilation is faster
and uses less memory.  MUPIP LOAD is much faster in UTF-8 mode.  There
are of course smaller enhancements, remedied misfeatures, and bug
fixes.  Details are in the GT.M V5.3-004 Release Notes (http://www.fidelityinfoservices.com/user_documentation/html/rn_tb/GT_M_V5_3_...).

Source code and executables for FOSS (AGPL v3) software can be
downloaded from Source Forge (http://sourceforge.net/projects/fis-gtm)
for the x86 GNU/Linux and Tru64 UNIX & OpenVMS on Alpha/AXP
platforms.  On other platforms, GT.M is not FOSS and is more
traditionally licensed.  Support on commercial terms is available on
all platforms.

For anyone using MUMPS implementations on Alpha/AXP,http://www.fidelityinfoservices.com/FNFIS/Markets/NonFinancialIndustr...
describes how to migrate from your current MUMPS on Alpha/AXP OpenVMS
to GT.M on x86 GNU/Linux in a series of small, reversible steps that
removes the need for any big-bang conversion.
