Paul Chang June 20, 2018 External Database Access (EDA) enables you to convert data stored in a Rocket UniVerse and UniData database to a first normal form (1NF) database, such as Microsoft SQL Server, then access that data using existing UniVerse BASIC programs, RetrieVe, or UniData/UniVerse SQL. For UniVerse running on a Linux platform, previously you had to purchase an ODBC driver to work with the EDA solution. Now, Microsoft provides you with ODBC Driver 17 for SQL Server on all Linux platforms. It is free and easy to install and use. UniVerse supports it starting with UV 11.3.1.6018 or later. In this blog, you will learn how to work with the UniVerse EDA solution with Microsoft ODBC Driver 17 for SQL Server on Linux. I’ll cover th

Michael Rajkowski April 12, 2017 In part one of the series “Python for the Rocket MultiValue Developer – Part 1 of 3 – Introduction” we discussed the architecture of the Python / MultiValue solution including the fact that the MultiValue and Python code both run in the same process. In this section, you’ll learn how Python interacts with the MultiValue Application Platform, through the use of the u2py module. THE U2PY MODULE The u2py module for Python allows developers to interact with the MultiValue Application Platform in the following ways: run U2 ECL/T

Paul Chang September 18, 2019 Overview External Database Access (EDA) enables you to convert data stored in a Rocket UniVerse or UniData database to a first normal form (1NF) database, such as SQL Server, Oracle and DB2 Server. You can then access that data using existing UniVerseBASIC programs, RetrieVe, or UniData/UniVerse SQL. UniVerse 12.1.1 supports a new EDA solution against MySQL Server. In this blog, you will learn how to work with the UniVerse EDA solution on Windows or Linux against MySQL server 5.6. I will provide sample steps to install &

Jonathan Smith February 6, 2019 Part 1 of 3 This blog post offers best practices related to implementing and using Replication, as part of a High Availability/Disaster Recovery (HA/DR) strategy. In Part 1, I’ll focus on preparation. I make no apology for this: U2 Replication is NOT an administration free option. In the event of a failure, your organization will absolutely depend on Replication. This blog series will help you to: Avoid common pitfalls that can be encountered in U2 Replication Understand the methods and strategies that have worked well for others Understand the tools that are available for monitoring and tuning of replication Preparation

Emma Breslin March 5, 2024 The Rocket MV team is pleased to announce the release of UniData 8.3.1, U2 Common Clients 5.4.1, and MV BASIC for Visual Studio Code (VS Code) 2.4.0 on February 26th, 2024. Rocket® UniData 8.3.1 UniData 8.3.1 HA/DR enhancements and bug fixes help you manage your replication environment more effectively. We’ve added a new script so you can stop and restart the repmanager, eliminating the requirement to restart UniData if the repmanager becomes unresponsive. We’ve enhanced the "invalid log sequence" message to include the actual and expected LSN number, which will assist you when debugging. We’ve added a skip option to the ud_rep

Paul Chang June 12, 2019 Using multiple unirpcd daemons to balance client requests can have a positive impact on performance. Also, using a different port for a specific application simplifies management. And, if users are on a newer version of UniData or UniVerse, they might want to use a different port specifically for a secure connection. On newer versions of UniDataand UniVerse, multiple Unirpcd Daemons with

Emma Breslin July 16, 2024 Rocket UniVerse 14.1.1 builds upon functionality implemented in version 11.4.1 and 12.2.1, making it the upgrade and modernization path for all customers on all prior versions. UniVerse 14 ensures business continuity and helps you manage your replication environment effectively with key HA/DR features. Replication is faster and more flexible with Field-Level Updates, since the entire record is no longer transmitted during u

Safwat Boulos January 24, 2019 We live in a fast-paced world where executives need real-time reports to make business decisions. Thus, users need information at their fingertips to deliver those reports. If your business-critical data lives in a UniDataor UniVerse MultiValue database, External Data Access (EDA) can help. What is EDA? EDA allows users to convert UniData and UniVerse nested relational data to First Normal Form (1NF), where it can reside in a SQL Server, DB2 or Oracle database, making the data easily accessible to standard tools such as Cr

Jonathan Smith March 13, 2019 UNIDATA HASHED FILES AND OVERFLOW In this first section we are going to discuss the two main types of UniData Hashed File (Static and Dynamic) and we’re going to discuss the two types of overflow that can occur in these files. The objective of file resizing is to minimize overflow as overflow is a performance overhead. 32-BIT V 64-BIT DYNAMIC HASHED FILES 32-Bit A UniDatastatic file or a sub-file of a dynamic file are limited to 2GB in size. Theoreti

Paul Chang July 18, 2018 External Database Access (EDA) enables you to convert data stored in Rocket UniVerse and Unidata databases to a first normal form (1NF) database, such as Microsoft SQL Server, then access that data using existing UniVerse BASIC programs, RetrieVe, or UniData/UniVerse SQL. For the UniVerse I-type fields, they can be mapped in many ways to SQL Server. This post will expand the mapping section of the External Database Access manual. Some additional mapping for I-type field dictionary items will be supported in UV 11.3.1.6018 or later version. In this post, you will learn how to work with the UniVerse EDA solution with I-type field dictionary items. I will provide you with sample steps for each of the different I-t

Hi All,We have a customer who are upgrading their hardware and OS to a Hyper-V environment running Windows 2022.Does anyone have any experience of running Unidata/Windows 2022 in a Hyper-V environment? Any issues we need to be aware of?Any comments/suggestions are much appreciated.Many thanks.Barry GreenCBS Software

Hi, We recently (last week) installed OpenQM 4.0-9 onto my new notebook. Today, I found that some spreadsheets that rely on the QMClient connection were not working (could not connect to server). It turns out that the QMClient.dll was installed into C:\\Windows\\SysWOW64 instead of C:\\Windows\\System32. Has anyone else struck this? And can someone from Rocket comment on why this is occurring? [Those Windows folder names are quite misleading. System32 is supposed to contain 64-bit libraries, while SysWOW64 contains 32-bit libraries. Who thought that was good naming?] Cheers, Brian------------------------------Brian SpeirsWellington NZ------------------------------

Hey all- I've managed to locate the Unidata Dictionary, Commands, Basic and Administrator manuals. But, after years of being on other platforms, I'm really struggling with queries and report formatting in UniData. Operators like BY-EXP, ID.SUPP, HEADING, etc, keep popping into my recollection, but I'm still having a difficult time with syntax and order. The UniBasic manual helps to some extent, but I'm hoping there might be a more in-depth Manual (or training) specific to creating and formatting reports from ECL.thanks in advance for any assistance- Rich------------------------------Richard LucibellaDirectorRocket Forum Shared Account------------------------------

Does Rocket have any future plans for a uvnet comparable for uniData?

Hi, We are experiencing issues with our UniVerse session, where randomly the session gets frozen and becomes unresponsive. It's random and occurs once or twice per month, and the only solution we have is to restart UniVerse and it starts working. Has anyone experienced this issue or is there a fix around this. We are using Centos to host UniVerse 11.3.1 and this issue has started since November last year.   Below is a sample error message : kernel: uvapi_server[9052]: segfault at 0 ip 00007f7aa5a6b586 sp 00007fff414b15e8 error 4 in libc-2.17.so[7f7aa5938000+1b6000]kernel: uvapi_server[9045]: segfault at 0 ip 00007ff5418e0586 sp 00007ffc9b5592a8 error 4 in libc-2.17.so[7ff5417ad000+1b6000]  Thanks,------------------------------Amarendra RakeshBusiness System ManagerSMC CorporationSydney NSW AU------------------------------

I've noticed that a number of lppick processes are hanging around long after they should have exited.  I've seen this in v9, but I figured it was just a bug that would get resolved with v10.3.4.  Apparently not. :( Example: In the past, I've just killed these processes but before I go about that this time, I wanted to find out if there was something I can do to ensure that it doesn't keep happening. I should note that this isn't isolated to one of my plants - here's the list from my other plant: Both hosts are on RHEL 9.4 and using D3 v10.3.4. What do I need to do in order to keep these orphan processes from stacking up? Thanks folks! g. ---------------------
