Li, The documentation site has moved to https://fis-gtm.sourceforge.io/. 7.1-011 release notes is here : https://fis-gtm.sourceforge.io/releasenotes/GTM_V7.1-011_Release_Notes.html We will soon auto-redirect the old documentation to go to the new one (or just point) . Sorry about the delay in doing that. We are still working on few things with respect to documentation.

@gtmsupport @harikishore Are there any plans to publish release notes for 7.1.011? Or is it secret information?

GT.M INstall V7.1-008 in Ubuntu 25
-
The error "%GTM-E-ZGBLDIRACC, Cannot access global directory /home/dev/gtm/data/gtm.gld. Cannot continue." states that it could not find the file gtm.gld For "mupip create" to work, it needs a global directory first. You can create that by executing $gtm_dist/mumps -run GDE exit This will create a global directory with the defaults. For more information on that refer to the GDE chapter in the Administration and Operations Guide

Can I install GT.M from Ubuntu package manager using sudo apt install fis-gtm, will it install everything already functional?

Hello, We are currently using GT.M version V63010 on Ubuntu 22.04. Our database is configured with the default value for the Access method (BG). However, we have noticed that GT.M seems to rely heavily on swapping rather than utilizing available memory. The online documentation has not provided a clear solution to this issue. Could you please advise on how to monitor memory usage and enforce memory utilization over swapping? Thank you for your assistance.

Hi all, I need to calculate a CRC32 checksum on text files. Does this kind of code exist on the programmer's guide ? If not, it will be kind if someone could provide a sample routine. Thanks.

Precision is not accuracy

Thanks for pointing this out Bhaskar. The next publish of the documentation will have the changes.

K.S. Bhaskar posted a comment on ticket #41
Thanks @gduzan. Please close this ticket, as SF evidently doesn't give me the right to do so, even though I created it.
-
It was added for use in our regression testing and is not supported for use in applications.
-
Also the argument for $ZTIMEOUT is an expr that is XECUTEd, not a labelref that is DOne.

@gtmsupport Hi, according to the documentation, version 7.1-007 was released a month ago, are there any plans to post it here?

I've finally found what was the problem. A probe has been set to initiate a socket with GT.M. Unfortunatally, it does not wait for the response and close the socket on its side.
-
Hello, We've finally moved to systemd and haven't encounter any problems of course. There is just a slight impact on performance. Thanks,

Hello all, We're still using version V6.3-010 (quite old now). We are considering upgrading but for now we need to install it on a brand new Ubuntu 24.04 server. Unfortunatally, there's a problem on installation using the classic 'gtminstall' script. This version seems to be dependant on libncurses5. Here is the logged error in 'configure_xxx.err' file : ./geteuid: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory On Ubuntu 24.04, we...

Hello, We've installed GT.M V63010 on Ubuntu 22.04 server. I know that this version is quite old now. The database has been installed on a xfs partition. In our backup process, we're using 'mupip integ' to check our database. This task is really slow on this server compared to our old 'debian' server (*10 time slower) . Is it due to the xfs filesystem ? Is there a simple way to move from xfs to ext4 filesystem ?

FIS GT.M Support posted a comment on ticket #40
That depends on the kind of audit log you are looking for: * journal files capturing database updates are configurable as database characteristics and accessible in parsable form * principal device activity logs are configurable in the restriction facility * application audit logs are frequently stored in databases, but take care to choose a design that limits contention

Zeeshan Ali posted a comment on ticket #40
How does GT.M store audit logs, as a log file? or in a db table? How can audit logs be enabled and configured?
-
GT.M does not currently support ARM processors.
-
Thank you for your quick response! Do you happen to know of instructions to install GT.M on a mac os with M1 chip?
-
V5.3 is far out of date; V7.1-004 is the latest release; Debian repositories have a recent release for download. Documentation appears at: http://tinco.pair.com/bhaskar/gtm/doc GT.M can be installed in a docker environment, but we are not aware of any such available dockerfile

One suggestion is to delete all application object files before recompiling. Another is to enable core dumping and look at the stack and the context as a way of diagnosing the issue or of eliciting more useful help.

John: GT.M provides a Non-SQL key-value store database embedded in an implementation of the M language. You can find documentation at http://tinco.pair.com/bhaskar/gtm/doc/. Based on the limited information in your post, I'd guess your best bet might consist of a mupip bytestrem backup from transaction 1 followed by replication with a filter. However, in addition to mastering the mechanics of data migration, depending on the architecture of the replacement application, you may find the data mapping...

I am working with one of my clients who wants to re-architect their applications. They are also looking at migrating from GT.M database to MongoDB. What are the options available that would have the least amount of downtime on their production application? I want to know the options for CDC migration. Any help is appreciated. I am looking at around 2 TB of data. Downtime tolerance during migration is not more than 2 hours. I could not find anything on CDC in GT.M database, especially related to ...

Hello. I installed successfully GTM 6.3 on openSuse Leap 15.5. But after GTM installation I want to do a routine update and globales update. When I make globales update it works well but when I make routine update it appears to me Segmentation fault (core dumped) error. Can anyone help me? Thanks
-
This looks like an issue which was fixed in GT.M 6.3-010. http://tinco.pair.com/bhaskar/gtm/doc/articles/GTM_V6.3-010_Release_Notes.html#GTM-9190 Note that 6.1 is over ten years old, so it isn't surprising that it doesn't work well with much more modern operating system releases.
