We have released V3.0.78 of IBM z/OS Connect with a new programmatic choice for developers creating OpenAPI 3 API requesters and API provider API First. Since IBM z/OS Connect v3.0.65, developers have been able to create the API requester and the generated artifacts only with COBOL. As of IBM z/OS Connect v3.0.78, developers can also create the same artifacts using PL/I. The IMS mobile templates have been updated with the note that existing IMS service provider configurations will not be affected by this change that is available from v3.0.78. For more information, see PH59261: z/OS Connect V3.0.78 and if you’re new to IBM z/OS Connect, ...
In z/OS 3.1, z/OSMF Sysplex Management plugin provides a new feature to allow the user to calculate CF structure sizes and directly apply changes to their CFRM policies (and rolled back to z/OS 2.5 with APAR PH47561). The main function of the CFRM Policy Editor CF Sizing is to perform CF Structure Sizing within a policy. This function is useful when you introduce a new workload or application, change an existing workload in some way, or want to modify your current structure sizes. Compare with current CFSizer website , this new function has below advantages: . Minimize manual input/re-input of sizing data. . Persistence of user sizing ...

Nachdem die Schweiz bereits im Januar mit der Gründung ihrer zTalents Gruppe gestartet hat, hatten wir am 6./7. Februar das erste Treffen unser "new new" to IBM Z Young Talents im Rahmen des EnergiZ@DACH Programms in Frankfurt. "new new" bedeutet dabei "gerade angefangen" oder "erst kurz dabei" auf dem Mainframe. Wir hatten 19 Teilnehmer, einen tollen Austausch und viel netzwerken und Vorträge aus dem Labor Böblingen von zum Thema "Hochverfügbarkeit" mit Martin Recktenwald und Marco Krämer und zum Thema " Typische Mainframe Umgebungen – von Monosystemen über Sysplex bis hin zu GDPS" mit Michael Grossmann von SVA. Es hat viel Spaß gemacht und es war ...
Honoring Leadership: From Global Leadership to Technological Pioneers As we celebrate Presidents' Day, a day to honor the leadership and wisdom nationally & globally, it's also an opportune moment to draw parallels between historical figures and IBM's pioneering role in the realm of IBM Z, Artificial Intelligence (AI) and Machine Learning (ML). What Is Machine Learning? Machine Learning (ML) is a branch of Artificial Intelligence (AI) and computer science. It focuses on the use of data and algorithms to mimic the ways in which humans learn. Learn Machine Learning w/ IBM Machine Learning and IBM IBM has a rich ...
従来、特定の z/OS システムを管理する SMP/E CSI ( Consolidated Software Inventory )は、システム担当者(システム・プログラマー)が把握しているのみで、何らかのプログラム・インターフェース経由で知ることはできません。 これに対し、 z/OS 3.1 では、「 UUID 」( Universal Unique Identifier )を z/OS SWI (ソフトウェア・インスタンス)と関連付けることで、 REST API によるプロパティー取得ができるようになりました。 ※例えば、 POST メソッドで取得した「 UUID 」を GET メソッドにて指定することで、対象の z/OS ソフトウェア・インスタンスに含まれる CSI 情報、導入済の製品情報などが入手可能 ※この新機能は、 LPAR または VM 下で稼働する z/OS ソフトウェア・インスタンスのみが対象 ・・・ プログラム製品やミドルウェアは対象外 ★「 UUID 」は、オブジェクトを一意的に識別するために使用される 128 ビットの値 ※ 32 個の 16 進文字( 0 ~ 9 、 A ~ F )で表現され、「 XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX 」形式で表示( 4 つのハイフンで区切られた、 8-4-4-4-12 形式) (例) bbc9e8d6-bd61-4f11-af48-ff500fffc178 ...
In my earlier post, I introduced the ingredients needed for creating a visual replica of all z16 I/O connectivity (using the IBM CHPID Mapping Tool /CMT and the Visio stencils provided within IBM ResourceLink). Constructing a Visual Representation of z16 Hardware and I/O Mapping - Part I - IBM Z and LinuxONE Community . In Part II, I will show you how to use these tools to construct a diagram showing all I/O drawer cards, their connections (e.g. FICON, OSA, zHyperLink, etc.). I will also address how to provide the same kind of reference for the CPC drawers (ICA-SR Coupling Links). In Part I, I provided a diagram showing the layout of a 2 frame z16 with ...

2022 年 7 月 10 日時点で、 Shopz オーダー時に指定する導入方法として「 CustomPac installation dialog 」(従来型 ServerPac )の選択肢が削除され、それ以降は、 z/OSMF ソフトウェア管理タスク( Software Management )とワークフローを用いて導入する新しい PSWI 形式(ポータブル・ソフトウェア・インスタンス)の ServerPac のみが使用可能 になりました。 ※ PSWI は、 SWI (ソフトウェア・インスタンス: SMP/E CSI 、 Target 、 DLIB 、非 SMP/E 管理)に含まれるデータセット群をアーカイブした一連のファイルで構成 この変更は、 z/OS 、 CICS 、 Db2 、 IMS などをはじめ、 Shopz でオーダーする全ての IBM Z ソフトウェア製品の ServerPac に適用されるため、「 z/OSMF 」稼働が各種 ServerPac 導入の前提となります。 z/OS では、 2021 年 9 月 30 日利用開始の「 z/OS V2R5 」以降、 PSWI 形式の ServerPac が提供されています。「 z/OS V2R5 」の場合、オーダー時期によっては従来型 ServerPac も使用可能でしたが、 2023 年 9 月 29 日に利用開始を迎えた 最新の「 z/OS 3.1 」では、 PSWI 形式の ...
APAR PJ45801 added support to the z/TPF automated test framework for test case overrides and intercepts with the TPF_TC_OVERRIDE, TPF_TC_INTERCEPT, and TPF_TC_COMPLETE macros. As part of this support, hooks in the CP were activated during an IPL if the z/TPF automated test framework was enabled. The activation of these hooks can delay the IPL process on a z/TPF system unnecessarily. Defer z/TPF automated test framework hooks improves IPL performance by deferring the activation of the override and intercept hooks until the first time that the z/TPF automated test framework is invoked after an IPL. The activation occurs even if the first invocation of the z/TPF ...

With the increase in memory on z/TPF systems, the amount of data included in dumps is growing. To reduce the dump size, PJ47200 provides you with the capability to include selected data in the dumps generated by the offline diagnostic output formatter (DOF), also known as the dump post processor. To reduce the dump size, you can specify the following DOF options in the JCL EXEC statement. · SELECT · OWNER SELECT The SELECT option which was introduced by PJ39499, is enhanced with the capability to dump one of the override areas created by the IDATB macro or ZIDOT command. If an in-use block type (IXWUSE) is specified ...

IBM Z Anomaly Analytics (ZAA) provides a platform to collect and analyze Key Performance Indicators (KPIs). In the latest continuous delivery release, several KPIs are marked as deprecated, meaning that we plan to remove them in a future release. The result will be more focused anomaly detection and reduced noise in the anomalies detected. The first release of ZAA supported anomaly detection only for Db2. We have added support for CICS regions, MQ Queue Managers, IMS regions and RMF data from z/OS. We now support 5 subsystems and over 400 KPIs. Our customers needed help understanding the meaning of the individual KPIs and the significance of an anomaly ...
Linux on IBM Z and IBM LinuxONE use the s390x hardware architecture, so for some applications a little work sometimes has to be done so they compile and run as expected. This work is often done as a collaboration between the open source projects themselves and a team at IBM that helps with validation that the software is working as expected. This effort is an on going collaboration with every release of the software needing to be validated. For the month of January 2024, the team worked to also validate the latest versions of the following: Apache ActiveMQ Apache Camel Apache CouchDB Apache Hbase Apache JMeter Apache Kafka Apache Solr ...

EZ Ordered Indexing!

Please check out our No SQL for z/OS? So EZ! blog post for a high-level background on EZNoSQL. We are still enthusiastic about EzNoSQL and even more excited to announce this new functionality! EzNoSQL now offers you two choices for your primary index: Ordered and Unordered. Let’s talk about each option and what it means for you with EzNoSQL: Unordered Index: Unordered Index randomizes the key-values to store the documents in the database. Using unordered index means that the keys cannot be searched sequentially and that the key-values will not be returned in order of insertion. Unordered index does not introduce ...
