Paul Chang May 15, 2019 Overview External Database Access (EDA) enables you to convert data stored in the Rocket U2 database to a 1NFdatabase, such as Microsoft SQL Server, then access that data using existing UniVerse BASIC programs, RetrieVe, or UniData/UniVerse SQL. There are a number of reasons to join EDA tables. When combining rows from multiple tables in one query, you need to use the JOIN command. There are several types of joins including inner join, outer join and full other join. The simplest join is called equal join. By default, the SQL Server database is set to the “SQL_Latin1_General_CP1_CI_AS” collation. The primary key of an EDA file is created by the “SQL_Latin1_General_CP1_CS_AS” collation. So, when you are trying to use an equal join on these two collation fields, you’ll get the following error “’cannot resolve collation conflict between “SQL_Latin1_General_CP1_CI_AS” and “SQL_Latin1_General_CP1_CS_AS” in the equal to operation’ #468’”. When you map the STATES file

Mary Schulz February 20, 2024 This is the third MVX: Performance release focused on improving replication as part of a MultiValue HA/DR strategy. We’ve added replication charts to provide you with more insights into the replication status and latency of your MV databases. You can now see four different charts showing you the subscriber latency trend, the estimated time to catch up, and the distribution of replication data for all groups or a selected group. This is a big improvement over using XAdmin, where you had to do the mental math to understand the estimated time to catch up. You can also use the Graphical Range drop-down menu in MVX: Performance to select a time range for viewing the data trends. Two of the replication charts now support aggregated group data, which means you can see the combined data for multiple groups in one chart. This can help you compare and contrast the replication performance of different groups. To learn more about these and other features, please refe

Ben Peach June 20, 2023 If you’ve ever configured a Rocket UniVerse or Rocket UniData (U2) product for SSL, you’ve likely come across the option to set ‘Authentication Strength’. The options are Strict and Generous. While that wording is descriptive enough to tell you that ‘Strict’ is probably better when it comes to security, what does it mean in real terms? First, it’s important to know that secure communication these days is mostly done using a protocol called TLS (this includes U2). TLS, or Transport Layer Security, was launched in 1999 as an upgrade to the Secure Sockets Layer (SSL) version 3.0. TLS can be thought of as SSL 3.1 or 4.0. Some argue that the name was changed simply to avoid any legal issues with SSL’s original creator, Netscape. ‘SSL’ is still generally used to describe secure communications; the terms SSL and TLS are used interchangeably. This article is no exception. If the systems communicating with each other are all U2 databases, you can simply set them all to

Brian Cram November 14, 2024 The Rocket® D3® MVS Toolkit versions 2.2.3.121 and earlier required activation. We no longer have the ability to activate those versions. If you are running an older version, we highly recommend that you upgrade. If you decide to continue to run on the older version, at least make sure you have a current Web Service Export just in case your Toolkit installation breaks, and you are forced to upgrade. A Web Service Export is much like a Pick file-save: hopefully you never need it, but if you do, you'll be glad you have it! Upgrading the MVS Toolkit has more benefit that just removing the need for activation. The older Toolkit versions use Jetty and Java versions that have been deprecated because of security issues. If you have questions or need help upgrading, please contact Rocket D3 support.

August 8, 2018 Traditionally, U2 applications need to provide OS-based user credentials (namely, OS user account names and passwords) to establish a connection to U2 database servers, which then perform authentication based on the credential and set the identity of the U2 processes accordingly. With the proliferation of the Cloud, more and more users are moving their applications into the cloud where OS-based authentication schemes are increasingly getting harder to maintain and use. Some U2-based application vendors are beginning to adopt third-party Identity Management (IdM) products for their in-cloud applications. With such an approach, the end users are no longer issued or asked to provide OS-based credentials for logging into the applications. Instead, they authenticate to the third-party IdM where an access token is returned to the application after a successful validation. The application consumes the token and provides services according to the granted rights embodied in the

Jonathan Smith July 25, 2024 With the increasing use of containers and cloud environments, the demand for seamless, automated software installations and upgrades has grown. Manual authorization at the end of UniVerse and UniData installations or upgrades is no longer acceptable. To address this, Jonathan Smith, Rocket® Software Principal Technical Support Engineer, has developed the "Rocket U2 Auto License Python Script," which automates the license authorization step, complementing the 'silent' (aka no manual intervention) installation capabilities of UniVerse and UniData. Jonathan designed the Rocket U2 Auto License Python Script to work across all current GA releases of UniVerse and UniData. It is also compatible with older versions of UniData from 7.3 onwards and UniVerse from 10.2 on Unix and 10.3.6 on Windows. The script operates whether UniVerse and UniData are running or not. Notably, the script supports UniData's feature of licensing without restarting. The script retrieves

Michael Rajkowski March 29, 2017 Rocket Software has added support for the Python development language to Rocket® UniVerse 11.3.1 and Rocket® UniData 8.2, on Linux and Windows only. Python will also be added to Rocket® D3 in the second half of 2017. Adding Python support gives experienced and new MultiValue developers the opportunity to code in one of the most popular development languages available today. To help developers get started Rocket created a Python community page that hosts links to code samples, documentation and lots more. PYTHON IN MULTIVALUE – THE BASICS Python now sits at the same level as the other access method used by the MultiValue developer. Our MultiValue Python module consists of two parts. The main access point for the Python developer is the u2py module, which is Python code. The u2py module calls a module written in C. Since both Python and the U2 databases are written in C, it is compatible and can be embedded into the database. The entire box represents

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.

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

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------------------------------
