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.
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]

The updates to z/TPF support for Java address various defects. They are designed to work with updates made to the IBM® 64-bit Runtime Environment for z/TPF, Java™ Technology Edition, Version 8. All of the z/TPF components, as well as the IBM Java runtime shared objects, can be loaded to a z/TPF system by using either the E-type loader (OLDR) or the image loader (TLDR). Apply both updates to the z/TPF system at the same time. Download and install the PJ44655_ibm-java-jre-8.0-4.5.tar.gz package from the... [More]

Greater than 64 KB TCP read support increases the maximum amount of data that can be received on a single TCP socket read-type function from 64 KB (65535 bytes) to 1 MB (1048576 bytes). With this enhancement, the cost of reading large TCP messages in customer applications is significantly reduced in terms of application complexity and CPU consumption in the z/TPF system. Non-SSL z/TPF WebSphere MQ sender/receiver channels, SRVCONN channels, and MQ Client are updated to use this support when reading large MQ messages. For more... [More]
User exits for MongoDB requests provides two user exits for you to control pre-request and post-request processing by using z/TPF support for MongoDB. You can use the pre-request user exit (UMON_pre_request) in the following ways: Check resources or status for each received MongoDB request. Reject requests and return the reason why the requests are rejected. Optionally disconnect the MongoDB session from the z/TPF server for MongoDB. With the post-request user exit (UMON_post_request), you can apply accounting logic based on the... [More]
IBM delivered z/TPFDF default key support for z/TPF support for MongoDB (APAR PJ44378) in April of 2017. This support provides a way for you to access z/TPFDF files that do not have default keys defined in the z/TPFDF database definition (DBDEF). Previously, the default keys could be defined only in the DBDEFs and doing so was optional. Many DBDEFs do not have default keys defined; instead, the z/TPFDF application uses a DBKEY macro or dfkey() function to specify the file organization when the application inserts or updates LRECs. With... [More]
At the TPF User's Group meeting in Scottsdale, AZ, a hot topic was held on PUT Delivery Model Changes Not all customer representatives were able to attend the session, so we are posting this call for sponsor users to participate in phone calls and/or web meetings to provide feedback on the APAR reference data, prerequisite data, tar packages and tools that we currently provide. The responses collected will be used to enhance our deliverables, possibly by reformatting information, removing information that is redundant or no... [More]
