With z/TPF support for MongoDB, when accessing a document (or z/TPFDF subfile), either all the data within that subfile is exposed to the end user or none of it. There are mechanisms as part of z/TPF user security that can prevent an end user from seeing a MongoDB collection (or z/TPFDF file), however, there is no mechanism for an end user to see a subset of the data in a MongoDB collection. This becomes an important concept as some customers have z/TPFDF files that can contain a mix of end-user information. Opening this z/TPFDF file for... [More]

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]

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]
