Rocket® U2 | UniVerse & UniData®

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 the sample steps that will convert the UniVerse CUSTOMER file data into SQL Server tables. Note You must order an additional UniVerse EDA package license to work on this solution. You can verify the EDA license information using the “uvregen -z” command. R

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/TCL commands ** read/write U2 files ** handle U2 dynamic arrays manage U2 SELECT lists call U2BASIC catalogued subroutines control U2 transactions ** Introduced in this article GETTING STARTED WITH THE U2PY MODULE The installation of Rocket UniData and Rocket UniVerse includes Python (version 3.4.1). The initial install of Python sets up the needed “.pth” file to point to the u2py module. The u2py.py module provides the interaction

Emma Breslin April 30, 2024 The Rocket MV team is pleased to announce the release of Rocket UniData8.3.2 and Rocket MultiValue Performance Experience (MVX: Performance) 1.10. UniData 8.3.2 is the first UniData release certified with the Rocket MultiValue Performance Experience (MVX: Performance) 1.10, which is available for our customers on maintenance. MVX: Performance monitors the performance of your UniData server and provides DBAs or developers with a better way to track down issues. It determines the root cause of issues, including the server, the operating system, the hardware, or a combination. DBAs can easily receive alerts when over 40 performance monitoring events occur, so constant monitoring is not required. In addition, UniData 8.3.2 and MVX: Performance 1.10 provide you with an enhanced replication experience, bolstering High Availability and Disaster Recovery (HA/DR) capabilities. UniData 8.3.2 extends the security features introduced in UniData 8.3.1, which included

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 & configure the setting to connect to MySQL Server 5.6.Note: You must order an additional UniVerse EDA package license to work on this solution. You can verify the EDA license information using the “uvregen -z” command.

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 HA/DR 101. The first thing to do when setting up your machines within Replication – primary and standby (the most common configuration) is make sure that both of these machines have fixed IP addresses – their IP addresses do not change. Then, setup a high-level name at the DNS level such as ‘live’- to connect to the current primary or

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_repadmin command to facilitate recovery from stalled subscriber groups. UniData 8.3.1 security upgrades and enhancements help keep your applications and business safe and compliant. By upgrading to OpenSSL v3.0, UniData supports a wide array of protocol levels. OpenSSL 3.0 includes a major architectural change from OpenSSL 1.1 and bring

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 different port numbers on Microsoft Windows is supported. When you install UniData or UniVerse, the unirpcd daemon uses deaful port # 31438. This allow all U2 clients ti connect to the UniData or UniVerse server without any additional setting. You might want to start two unirpcd daemons with two different ports for shared unirpcd daemon loading. This blog provides details on U2 clients working against the Unirpcd daemon with different port setting., e.g. # 32438.

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 updates, only the individual field that was modified is replicated - significantly improving performance! Facilitate Replication recovery with the uv_repadmin skip option which allows you to skip an incomplete transaction that has caused replication to stop processing. By using the skip option, administrators keep Replication processing and avoid log build-up and the eventual reset and refresh of Replication due to a stalled group. Facilitate Replication recovery with the enhanced uvreptool. When Replication has stopped processing due to

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 Crystal Reports or any of the many open source products. EDA benefits and implementation EDA allows users to seamlessly transform your UniData and Universe nested-relational data to a normalized form where external SQL tools can access your MultiValue application’s data. Since most users are accustomed to SQL, EDA makes them independent, allowing them to manipulate the data and generate the reports of their choice. EDA lifts the burden fr

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. Theoretically a UniData dynamic file can grow to 500GB but the internal management of these multiple sub-files requires complicated code and multiple file I/O operations and hence reduces performance of the files. The block-size of the data file is limited to 16K and as data records are now getting larger and larger this also is a performance limitation of the 32Bit model. 64-Bit The 64-Bit data model introduced at UniData 8.1 will resolve these issues so that data files will have virtually no restrictions on file siz

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-type field conversions against SQL Server. Note You must order an additional UniVerse EDA package license to work on this solution. The EDA license information could be verified using the “uvregen -z” command. REQUIREMENTS Rocket MultiValue product Ver

Managing product marketing for the MultiValue business unit means that I have an opportunity to interact with customers, and hearing how Rocket products have improved services and offerings for their customers.Using a combination of UniData and U2 RESTful services, Fudtrak has created a mobile app allowing users to locate, view the menu of, call, and socially engage with their favorite food trucks.
