QPASVRP

Target 5250 display station pass-through primary server job. This job log is for target pass-through communications functions.

QPASVRS

Target 5250 display station pass-through secondary server job. These contain more detailed messages for target pass-through communication functions

Subsystem jobs (QINTER and QCMN)

Interactive subsystem and communication subsystem. These job logs are for subsystem jobs.

For more information on pass-through primary jobs, see the Remote Work Station Support book.

Solving communication problems using communications trace

Sometimes, program debugging tasks are easier if you can trace the data that is sent and received on the communications line or within the network server. To run a communications trace, use the following commands:

STRSST (Start Service Tools)

The STRSST command takes you to a menu of tools to obtain error log information and communications trace information. For a detailed description of system service tools, see: “System service tools and communication problems” on page 82

STRCMNTRC (Start Communications Trace)

The STRCMNTRC command starts a communications trace for the specified line, network interface description, or network server description. The communications trace continues until one of the following occurs:

vThe system runs the End Communications Trace (ENDCMNTRC) command

vA physical line problem causes the trace to end

vThe Communications Trace function of the STRSST command ends the trace

vThe *STOPTRC parameter is specified, and the buffer becomes full

ENDCMNTRC (End Communications Trace)

The ENDCMNTRC command ends the trace currently running on the specified line, network interface description, or network server description. The ENDCMNTRC command saves the communications trace buffer and the associated System Licensed Internal Code (SLIC) data.

PRTCMNTRC (Print Communications Trace)

The PRTCMNTRC command writes the communications trace data for the specified line, network interface description, or network server description to a spooled file or a database file. The system can print trace data multiple times in either form, and parameters on the command allow for dividing and formatting of the data.

DLTCMNTRC (Delete Communications Trace)

The DLTCMNTRC command deletes the communications trace buffer and associated SLIC data for the specified line, network interface description, or network server description. The communications trace can be deleted once the trace has ended.

CHKCMNTRC (Check Communications Trace)

The CHKCMNTRC command returns the communications trace status for a specific line, network interface description, or network server description. The CHKCMNTRC command returns status for all of the traces of a specific type that exist on the system. The system returns the status through a message.

TRCCPIC (Trace Common Programming Interface (CPI) Communications)

You can start to trace Common Programming Interface (CPI) Communications either before running a job or after a job is active to find out where the error might have occurred. The TRCCPIC command captures information about CPI-Communications calls that is processed by your program.

For more information on how to access System Service Tools, see the Backup and Recovery book.

AS/400 specifications

The IBM AS/400, now known as the IBM iSeries, is a midrange computer system that has been a cornerstone of enterprise computing since its introduction in 1988. Designed to provide a robust platform for business applications, the AS/400 is celebrated for its reliability, scalability, and integrated database capabilities.

One of the key features of the AS/400 is its Integrated Operating Environment, which blends hardware and software resources seamlessly. This integration allows businesses to execute diverse workloads, ranging from traditional applications to modern web-based services, all on a single platform. The operating system, OS/400 (now IBM i), offers a rich set of APIs and tools for developers, simplifying application development and management.

Another standout characteristic of the AS/400 is its built-in database, DB2 for i. This powerful relational database management system allows for efficient data handling and provides advanced features such as support for SQL, XML, and JSON, making it easier for businesses to manage their data and integrate it with other systems. The database's tight integration with the operating system enables high performance and security.

In terms of scalability, the AS/400 can accommodate small businesses as well as large enterprises, with the ability to support hundreds of users simultaneously. Its architecture allows for easy upgrades in hardware, meaning that organizations can scale their systems without replacing the entire infrastructure.

Security is another critical attribute of the AS/400. With a sophisticated security model, it offers built-in user authentication, access control, encryption, and auditing capabilities to protect data and applications from unauthorized access.

The AS/400 also supports multiple programming languages, including RPG, COBOL, Java, and PHP, giving organizations the flexibility to choose the development tools that best fit their needs. This diversity helps maintain legacy applications while also developing new ones that leverage modern technologies.

Moreover, the platform supports both traditional green-screen interfaces and modern graphical user interfaces, allowing organizations to transition smoothly into contemporary user experience paradigms.

Overall, the IBM AS/400 stands out as a resilient, flexible, and secure computing platform that enables organizations to effectively manage their business operations, streamline processes, and adapt to changing market demands. Its unique combination of integrated features and capabilities ensures that it remains relevant in today's fast-paced technology landscape.
