Docs on this setting describe it thus:Sets the number of hash buckets in the per-user locking table. Adjust this based on the number of concurrent locks a user may hold.andThe number of hash buckets for the per-process locking table. This parameter is highly application dependent, If the application requires a large number of locks in one transaction (more than 20), you should increase this setting to the closest prime number to the maximum number of locks per transaction.  So if we have identified our maximum locks per transaction is a rather large number, like 5000, then this calculation would derive to 4999. That does not seem to make sense.Is there any real-world feedback on this?

Greetings y’all!We currently have a development environment that I would like to have, on a regular cadence, updated with production data.Are any of y’all doing that know?  I’m being told by our VAR that it is next to impossible to do.

Hello, With an older release of D3 Windows (32bits), it was possible to connect to my D3 database using D3 Windows Class Library Reference.But, with the last release od D3 (64 bits), it doesn’t work. In D3 Programs, i don’t find this dll: D3clslib.dll Any idea ? ThanksRegards.Christophe.

This subject seems to be changing every week. (Yes, I have read the AI posting form ​@Mike Rajkowski  from 2 years ago, but we are living in the super-fast lane) I keep seeing new AI’s focusing on specific niches.   According to my Google AI search Claude and Lovable are the current AI that understand Unibasic (I always search for Unibasic because PICK and BASIC are too generic).  I decided to explore Lovable with a paid subscription and have had good results creating MV programs.  I even uploaded sample MV A/R accounting module documentation, and Lovable generated working screens and programs (not MV programs) with logic to connect with a LiteSQL database!!! I could use the screens on desktop and mobile devices. I do plan on fine-tuning my results to use Unibasic and see what it does.  What is everyone using, and for what purpose?  

The Rocket® MV team is pleased to announce the release of U2 Toolkit for .NET 3.1.3 on October 16th, 2026. The Rocket® U2 Toolkit for .NET Provider offers a free .NET data provider interface for Rocket UniVerse® and Rocket UniData®, while U2 Toolkit for .NET Developer adds the ability to develop in Microsoft® Visual Studio. U2 Toolkit for .NET 3.1.3 enhancements and improvements include:Support for .NET 10. The U2 Toolkit driver now supports applications running on the .NET 10 runtime, enabling .NET 10 applications to connect to UniVerse and UniData servers using the U2 Toolkit API. NuGet package availability. The U2 Data Client and U2 Entity Framework Core packages are now available directly from NuGet. Both packages target .NET 10 and can be installed and managed using the standard NuGet Package Manager in Visual Studio or the .NET CLI, simplifying dependency management and ensuring alignment with the latest supported .NET tooling. Updated End User License Agreement (EULA). The EULA

The default uvconfig values for these settings are:N_AFT 5000 N_AFT_SECTION 17 N_AFT_SECTION_BUCKET 23  These result in 294.12 files per SECTION, and 12.79 files per SECTION BUCKET. The N_AFT setting is too small for our needs so we will be increasing it. What I am interested to explore is what are the deciding factors needing consideration when adjusting N_AFT_SECTION and N_AFT_SECTION_BUCKET ? Should the current ratios be maintained as best as possible? For example, if N_AFT is set to 15000 a custom setting of 53 for N_AFT_SECTION would result in 283.02 files per SECTION and 12.31 files per SECTION BUCKET, which are close to the default ratios.Is this the best approach, or should I take a different track? 

Hello,We are currently using D3 and noticed that the number of RPC client connections is limited to 3, as shown by the :MAXUSERS command.During some long-running update processes (updating more than 4,000 items), an RPC connection remains allocated for 1 to 2 minutes, which can become a limitation when multiple processes run simultaneously.Could you please confirm whether the maximum number of RPC client connections can be increased?If so:Is this a configurable parameter? Does it require an additional license? What is the maximum supported number of RPC client connections?Thank you for your assistance.Best regards,

We are running Universe 11.3.1 on AIX 7.2.  I have 9 production accounts, mirrored on development and test LPARs.  That all adds up to thousands of files.     Formerly we used Fast c/s to monitor the entire system and stay on top of undersized files to prevent application slowdowns.  Unfortunately, it is no longer supported.Does anyone know of a similar application or product we could use?  If so, could you speak to the efficiency, ease of use etc.?Thanks in advance.

In all my years of using UniObjects for Java (UOJ), I have not paid attention to memory leaks in my syntax. They existed I am sure, but why bother if the process is pretty quick and was getting re-used by the web server. Of course, I would make sure that I closed files or make sure that I close sessions. I have a Windows machine running a 3.5 gig of memory that has been working for years.This year (2026) I upgraded the web server from Apache Tomcat 9 to Apache Tomcat 11. I upgraded Java from 17 to to 25. It was painful because of the Javax libraries which are no longer supported at this Java release and had to be replaced with Jakarta libraries. All of the all other libraries like BIRT, our Unidata/Universe Report writer, required updates to run in Java 25 as well.All of this increased my war file size by at 25%. That does not sound much but on this particular machine the margin of error was gone we would run out of memory several times a month. Every minute or so depending on what the

Had a customer report today that there’s a strange bug in the SB+ expression parser.  The sample he provided was this:IF(1,170,””)”MR2”)The spurious ) at the end should be a syntax error.  But it is not.    As long as all quotes are “, this returns either 170 or “)”MR2 depending on if the condition is true or false.  It also gets converted in EEGC as follows:IF 1 THEN   VALUE = 170END ELSE   VALUE = '")"MR2'ENDThis is not a crisis, but I wanted to post this in case anyone else happens to make the same mistake we did, with that extra “)” at the end of an expression. 

Greetings Rocketeers!We are on WIndows, preparing to move from Universe 11.xxx to 14.xxxHave any of y’all made this upgrade recently?  Were there any functional issues after upgrading?  Is there a test plan available anywhere we could get our hands? Many THX,

We are having trouble connecting via unirpc (MVQuery) to our Unidata 8.4 (Windows 25) server.  My work PC does not have a problem.  While RDP’d into the server, when I try to connect to an account, I’m getting → So far, 2 other PC’s get the same message.  I’m trying to setup logging/tracing for this.  I’ve placed ...\include\ud_database into TRACE_LEVEL=2.  If this is producing output, I can not find it.  What else can I do to track this down? Thank you,Jonathan WellsAptron, Corp.
