Technical experts from the IBM Transaction Processing Facility (TPF) Development Lab share knowledge and information about the TPF product set - including z/TPF, TPF Operations Server (TOS), z/TPF Database Facility (z/TPFDF), and the TPF Toolkit.
z/TPF support for Java™ (APAR PJ43892) changed the data types for the following fields in page 1 of the ECB: ce1dstmp, ce1extim, ce1istim. For more information about this change and how it might impact your programs, see serv ice bull etin 197 .
The TPF Lab will be closed Thursday and Friday, November 23 and 24, 2017 for the U.S. Thanksgiving Holiday. The Lab will resume normal operations on Monday, November 27, 2017. If you have a critical problem that requires immediate assistance, please open a Severity 1 PMR/ETR and offshift support will be notified. (See Op e n in g Pr o b le m s w i t h t h e S e rv i c e R e qu e s t T o o l for more information.)
IBM TPF Toolkit 4.2 Interim Fix 11 is now available on the update site. This fix contains maintenance and security fixes only. For more information on the security fixes, see the security bulletin . IBM TPF Toolkit administrators, please make note of the migration information in the updated service.html that is installed in the root installation directory after applying the interim fix. There is a co-requisite z/TPF APAR (PJ45031) for this interim fix that should be applied to your z/TPF development environment for the best user experience... [More]
Name-value pair collection allows you to understand and analyze system resource usage by horizontal and/or vertical annotations in your application. Horizontal annotations are made in your application using name-value pairs and can represent various aspects such as message type, message origin, customer, input values, and etc. Vertical annotations are made in your application by using ECB owner name change and can represent code packages, phases of processing and etc. Collection of the data occurs on the TPF system and the...

IBM Knowledge Center content for z/TPF PUT 14 was refreshed September 29 to add all enhancements and maintenance APARS that were released since the most recent refresh in August. Enhancements since the August refresh include the following new function: FARF6 fixed file record support Watch this space for information about new content for PUT 14 in IBM Knowledge Center.
An enhancement to z/TPFDF data event processing now available on PUT 14 allows you to use data events with more z/TPFDF databases. Event message data event support for z/TPFDF, provided with APAR PI18980, allows you to collect updated LRECs or full subfiles when a subfile is modified. However, data event processing only collects data when a z/TPFDF subfile is opened with a hold. It is possible for applications to make updates to a subfile that is opened without a hold, as long as the file’s database definition (DBDEF)... [More]
FARF6 fixed file record support extends the use of FARF6 addressing to fixed file records for both z/TPF and z/TPFDF databases. FARF6 is an 8-byte symbolic file address. Previously, FARF6 addressing was supported for only 4 KB long-term duplicated pool records and 4 KB short-term pool records. With this enhancement, FARF6 addressing can be used for fixed file records of all sizes: small, large, and 4 KB fixed file records. In addition, you can use FARF6 fixed file record types when you create a fixed file system (FFS) or pool file system (PFS).... [More]
A new aparPrereq command has been added to the zTP F AP A R D o wnl o ad t oo l s package. This command identifies the cumulative set of prerequisite APARs for a given APAR and will report on whether those prerequisites have been applied to a specified set of TPF_ROOT folders. Refer to the help message within the aparPrereq command for details.
IBM Knowledge Center content for z/TPF PUT 14 was refreshed August 30 to add all enhancements and maintenance APARS that were released since the most recent refresh in June. Enhancements since the June refresh include the following new function: Crypto Express6S and OSA-Express6S support

As was done for JSON in PJ44767, DFDL support has been updated to allow an XML document to be created directly from binary data without the use of infonodes through the use of the tpf_dfdl_buildDoc API. This makes creating an XML document not only easier and faster, but enhancements have been made to the resultant layout of the XML document to make the document smaller than when built using DFDL and infonodes. The resultant XML document will also be in UTF-8 encoding, thus avoiding the need to translate it from EBCDIC. ... [More]
With Logging for z/TPF Support for MongoDB (PJ44239), we now support the ability to log queries, administration, and updates made with z/TPF support for MongoDB (PJ42292). This article will help you create and setup a Logstash plugin to receive logging events. What is Logstash? While a visit to their website will give you complete information ( https://www.elastic.co/products/logstash ), in general, Logstash provides an extensible data processing pipeline. How do I setup Logging for z/TPF Support for MongoDB? For more... [More]

Even though DFDL support has provided the ability to create JSON from binary data for several years, the process used an internal tree structure known as infonodes. The building of this internal tree before building of the JSON document provided some additional overhead that could be avoided. DFDL support has been updated to create a new API (tpf_dfdl_buildDoc) that does not use infonodes in the process of creating the JSON document. This new API makes it not only faster, but even simpler to use. This update also... [More]
