PI86942 enhanced z/TPFDF data event processing on PUT 14 so that you can use data events with z/TPFDF databases that do not require holding a record for updates. Now, APARs PI89192 and PJ45037 provide additional enhancements to z/TPFDF data event processing on PUT 14.
z/TPFDF data event processing collected data event information only for updated LRECs or the full subfile. However, when data event information was collected only for updated LRECs, there might not be enough context for applications to properly process these LRECs. Unchanged LRECs in a subfile can contain identifying information for updated LRECs in the subfile, which might be needed. For example, unchanged LRECs might contain the customer ID, while the changed LRECs contain the latest transaction information. In this example, you had to write additional application or enrichment code to collect the customer ID.
With z/TPFDF APAR PI89192 and co-requisite z/TPF APAR PJ45037, z/TPFDF data event processing now provides the ability to automatically collect LRECs when the z/TPFDF subfile is opened for updating. This enhancement allows all or selected unchanged LRECs to be collected and provide missing context for changed LRECs. With this support, you do not need to write additional application or enrichment code to collect these unchanged LRECs.
