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.
In 2014, the IBM TPF Lab introduced Event Message Business Events, which included support for data events for z/TPFDF Files. When an application updates a database, data events allows the z/TPF system to automatically detect updates to customer databases and then capture, format, and transmit those updates as data events - all without changes to customer applications! With APAR PJ43301 on PUT 13, event message business events is extended to support data events for z/TPF files, which means z/TPF can create data events for both... [More]
With APAR PJ43020, the z/TPF TCP/IP stack now supports the use of UNIX domain sockets. UNIX domain sockets allow for interprocess communication on the same machine while using sockets as a transport mechanism. The implementation of UNIX domain sockets will allow application programmers another method of interprocess communication as well as make future porting efforts easier. UNIX domain sockets differ from internet sockets in that they bind to a unique file path on the file system rather than a port and IP address combination. UNIX... [More]

The XML, JSON, and DFDL parsers have been updated by PJ43545 and PJ43302 to support Unicode data. Previously, XML documents had to be translated to either EBCDIC 500 or 1047 code pages to use tpf_doc* APIs. Many Unicode characters, however, have no mapping in these EBCDIC code pages. For JSON, Unicode characters could be read from a JSON document but there was no method for adding Unicode data when creating a JSON document. For DFDL, only EBCDIC 1047 strings were supported. With PJ43545, Unicode UTF-EBCDIC encoded... [More]

The TPF Lab will be closed on the following dates: Friday, December 25 Friday, January 1 We will have limited staff working from now through the end of the year so you may experience longer than usual response times. The Lab will resume normal operations on Monday, January 4, 2016. We would like to wish our customers a Happy Holiday season and best wishes for the New Year!
The IBM Tivoli Monitoring Agent for z/TPF V1.1.2 Fix Pack 1 is available from the TPF Family Products: Tools web page and adds support for the following new z/TPFDF data collection counters. CACHE_PARTIAL_IO_COUNT CACHE_PARTIAL_IO_REQUEST CACHE_READ_HIT CACHE_READ_MISS BLOCK_READ_DEPTH APARs PJ43474 and PI44953 add support to continuous data collection to collect those new counters in the existing CDC_TPFDF metric.

The ZDECB command that is used to display information about active ECBs was updated to support filtering and sorting ECBs based on owner names and named limit sets. The USER parameter was added to display owner names and named limit sets of ECBs. Owner name notes: The owner name format is high.mid , where high is a high-level qualifier and mid is a mid-level qualifier. Qualifiers are case-sensitive and can be up to eight characters in length. If you enter a high-level qualifier without a mid-level qualifier, ECBs that have an owner... [More]

APAR PJ42459 provides support for the enhanced-DAT facility 2 (EDAT-2). During dynamic-address translation, EDAT-2 allows a region-third-table entry to specify the absolute storage location of a 2G-byte block instead of a segment-table origin. When DAT tables are set up to use EDAT-2, system performance may be improved due to a significant reduction in the number of TLB entries used for translation of addresses in the 2G-byte block, thus allowing the TLB entries to be used to translate other addresses. When PJ42459 is applied, the... [More]
A reminder that starting Monday November 16, 2015, the severity and critical columns will be removed from the z/TPF APAR data spreadsheet and corresponding csv files that are posted on the TPF Fam ily Prod ucts : Ma inte nanc e we b page. The HIPER column will remain as the single indicator of high impact and pervasive APARs. This change is being made to simplify APAR classification and help you to more easily identify high impact and pervasive APARs. Please note that to support the new csv file format,... [More]
It has been brought to our attention that some of the z/TPF APEDITs include maketpf build instructions for a program named " stcwp ". Please be advised that the " stcwp " program is a TPF Lab-only program and it should not have been referenced in the APEDITs. Please ignore any maketpf instructions you encounter for " stcwp ". Starting with PUT13, the APEDITs will not include references to the " stcwp " program.
By Barry Goldberg & William Lappan With enhanced format-1 globals support, the I-stream unique primary and extended global areas are relocated to system virtual memory (SVM) above 2 GB to alleviate memory constraints below 2 GB. Only the main I-stream is allocated below 2 GB. Previously, all format-1 global areas used SVM below 2 GB, which limited the number of I-streams that you could add to the z/TPF system. After you enable enhanced format-1 globals support, each application I-stream uses the same virtual addresses below 2 GB as the main... [More]

The DASD module status commands ZDMFS and ZDMOD DISPLAY have been updated to include filters for MPLF connect devices, offline devices and devices in module copy state. The information presented by these new filters was in each of the displays prior to this APAR, but the onus was on the user to find the desired modules by status. With this APAR applied the user can find modules by status more quickly. This is an aid in the case of finding offline modules or determining if your MPLF connect devices are evenly spread. In...

APAR PJ41739 corrects issues with network services database (NSD) processing that were introduced with APAR PJ42209. At the time that APAR PJ41739 was released, the additional problem with PJ42209 was not identified; therefore, APAR PJ41739 was not marked as fixing APAR PJ42209. The z/TPF APAR data spreadsheet has been updated to mark APAR PJ41739 as fixing APAR PJ42209. If you plan to apply or have already applied APAR PJ42209, ensure that you also apply APAR PJ41739. If you already applied APAR PJ42209 and cannot apply the correcting APAR... [More]

APAR PJ43266 - mymalloc support for z/TPF The purpose of mymalloc support is to reduce the performance impact when many ECBs are obtaining a large number of unique small sized ECB heap buffers. When a large number of unique ECB heap buffers are obtained a corresponding large number of ECB heap control table entries are obtained. Managing a large number of unique ECB heap control table entries has overhead. After the initial 151 ECB heap control table entries are used, a 4 KB system heap frame is obtained to hold the next 31 control table... [More]
