By Shigeki Kimura posted 4 hours ago
RACFデータベースのコピー処理で利用する「IRRUT200」ユーティリティー・プログラムに関して、下記のような機能変更が行われました。 【z/OS V2R5の変更点】 ■RACF APAR OA61995 （対象： z/OS V2R5）に対するPTF適用後は、 「PGM=IRRUT200」にてRACFデータベースのコピー処理を行う際、従来の「IEBGENER」ではなく「IDCAMS/REPRO」ユーティリティー・プログラムを呼び出すように変更 されました。 【機能変更に伴う考慮事項】 ■RACF 「SETROPTS WHEN(PROGRAM)」指定による「プログラム制御」が有効で、PROGRAMクラスに「IDCAMS」プログラム（SYS1.LINKLIBデータセット）を保護するプロファイルが定義されている場合、 「PGM=IRRUT200」の実行RACFユーザーは、該当プロファイルに対する「READ」アクセス許可が必要 です。 ■「PGM=IRRUT200」実行時のメッセージ出力（SYSUT2 DD）に依存した何らかの仕組みがある場合、 出力メッセージの番号、テキスト変更に伴う影響有無の確認が必要 です。 【関連情報】 ■「IEBGENER」の代わりに「ICEGENER」を利用する環境では、「PGM=IRRUT200」実行時に「DFSPARM DD」ステートメントを通じて「OPTION NOOUTSEC」指定を行う場合があります。z/OS ...

Technology is everywhere, we can think of a place where it is available. It also allows us to communicate better with the world, we can now communicate our opinions, our views freely, technology has done so much good that its negative effects are hard to remember; it has continuously improved itself and still has a lot of room for improvement. Without technology, how would we be able to meet our basic needs so easily? Even before the invention of technology, man was able to meet his needs. However, it was difficult and so primitive back then. Look at today’s food – fresh, preserved or processed, food of any type is available at your doorstep just anytime. ...

Business events ZBEVF command enhancements (APAR PJ45677)

By Chris Filachek posted 3 days ago
Business events ZBEVF command enhancements improve the usability of the usage and error displays and provide several new ways to search for and display business events and dispatch adapters. Previously, the ZBEVF usage and error displays listed information for all business events and dispatch adapters across all ECB activation levels. In most cases, however, you need the usage or error counts only for deployed items at the current activation level. The display contained more information than necessary because it included undeployed items or listed items multiple times if the same item was included in multiple loadsets. In addition, you could use the ZBEVF ...

z/TPFDF recoup optimized chain chasing (APARs PH30068 and PJ46413)

By Chris Filachek posted 5 days ago
z/TPFDF recoup optimized chain chasing reduces the amount of DASD I/O resources and the time required by recoup to chain chase z/TPFDF indexed databases that contain a large number of detail subfiles with only a single pool record. Recoup is a maintenance utility that is used to find all in-use pool records and return any lost pools to the z/TPF system. Standard z/TPFDF recoup chain chasing finds in-use pool records by reading all z/TPFDF subfiles and the pool records used by those subfiles. If your z/TPFDF database contains tens of millions of pool records or less, recoup might be able to chain chase the database in less than an hour. However, as your ...

Additional trace information (PJ46309)

By Michael Shershin posted 5 days ago
APAR PJ46309 includes several enhancements that enrich the data in ECB trace. This enriched data provides a foundation to improve the understanding of the flow and processing that is done by an application running on the z/TPF system. All of the enriched data is available in z/TPF dumps as well as in trace log output. Copy-on-write trace A copy-on-write event happens when a z/TPF program updates a static variable. The static variable is in the program rather than on the ECB stack. Because z/TPF programs must be reentrant and because the static variable is in the program, a copy of the 4 KB page where the static variable resides is made when ...

z/OS Application Modernization with IBM Metal C

By John Parke posted 5 days ago
z/OS Application Modernization with IBM Metal C The IBM z/OS XL C/C++ ® compiler has an option referred to as METAL C. This option generates IBM high level assembler (HLASM) code instead of an object module. The advantage of using this option is that the generated code does not depend on Language Environment ® support at runtime; although it may require the Metal C runtime library (in LPA). METAL C allows the use of embedded system service calls: STORAGE OBTAIN, OBTAIN macro, CATLOG/CAMLST, etc. Routines can be created using METAL C, and then called from an assembler or high-level language program. Metal C uses standard MVS linkage conventions. IBM suggests ...
