Introduction:
Journal print utility helps to find information about record logged on them, it also reads data from MVS log stream and displays in readable format. DWWJUP print utility use IXGCONN and IXGBRWSE to establish/disconnect connection to the log stream and reads the log stream contents appropriately. STARTTIME and STOPTIME parameters denotes ranges, also CICS VR journal print utility DWWJUP will supports INCLUDE, EXCLUDE commands to filter the data from a specific log stream to generate specific report.
Command format:

VSAM files are widely used in CICS applications and it contains critical information with a huge data set. It is always a better idea to keep a backup of these files in your PC for future use.

1.      Introduction
The CICS IA host side collects the Dependency, Affinity, and Command Flow data that can be used to carry out threadsafe analysis on a program or a transaction. The Load Module Scanner also provides the reentrant information to the report. The CICS IA threadsafe analysis report can be run in the CICS IA plug-in.
 
Threadsafe report can be used by the CICS programmer to analyse the thread safety aspects of their programs and for a better compliance with the best practices of the CICS application.

The Mainframe remains one of the primary workhorses of the computer world. Mainframes can process massive amounts of data; processing over 70 percent of the world’s most important computing transactions every day. Organizations like banks, credit card companies, medical facilities, stock brokerages, and others depend on the Mainframe for job processing and cannot afford errors and downtime. ​

The challenge with today’s developers is creating multiplatform applications. Developers come from different backgrounds and need to skill themselves to create applications and deploy them in multiple target runtimes.

With service recently made available in 4th quarter 2019, File Manager for z/OS provides several batch report enhancements. You can now split batch report sections across different DDs, rather than having all your output go to SYSPRINT, and certain batch reports now provide additional data set information for relevant input and output files.

Terminal emulators for IBM System Z (mainframes) and System I (AS/400) systems continue to be the primary user interface for many business-critical applications, systems programmers and application developers around the world. Terminal emulators are often underappreciated software, however their users typically require the highest level of reliability, availability, usability and security because they are essential enabler to access many core business applications and data.

​HCL Z Asset Optimizer (ZAO) is a market leading software asset discovery product for IBM z/OS mainframe systems. ZAO recognizes over 12,000 mainframe software products and features from IBM and other software vendors, as well as reports inventory and usage of in-house programs.  Benefits include:

​HCL’s Z Data Tools APIs (ZDT APIs) product now provides REST APIs to access Z data.
The Z Data Tools APIs REST Service enables client applications to access Z data using REST APIs. Client applications can read data sequentially, by relative record or database position, or by key.
