Intellectual records
Animated assembling, loading and execution process

 

As an IT player with more than 20 years experience, certainly i have a number records. `Some can be categorized as intellectual records. which are 2 major areas: 

Systems solution software

During more than 20 years, a lot of systems software products have been made, include tens of local utilities, command processors, exit routines, some interface, some local subsystems functions, and even solution products.  Most of them were gone, because they were kept in legacy tapes and/or floppies which no longer supported.  Only few of them can be rescued and currently are placed in freeware page in this site and CBT as file 535 and 536.

Regardless they were rescued, three of them were solution products where each provides a solid set of functions to establish a unique mechanism for certain system management.   There are listed below together with 3 zJOS-XDI products.  

Publications

To complete my intellectual contribution, i wrote some article in many IT bulletines.  In 1995 i wrote 3 mainframe books explaining detail about mainframe architecture and technology in both theoretical and practical aspects.  

Materials listed on my freeware page are some of my intellectual products

 

Systems Solution Software

1 zJOS/Sekar 
  Package zJOS-XDI
Function Integrated event manager solution
A subsystem with a set of service routines to intercept system events and execute user's defined action or set of actions.  In a networked z/OS and/or OS/390 hosts, users can define actions on certain host to be triggered by occurrence of event on either the same or other host in the network.

Platform z/OS, OS/390, TCP/IP
First released 2004
2 zJOS/Puspa
  Package zJOS-XDI
Function Integrated automatic job scheduler solution
A subsystem with a set of service routines to manage JES2-based jobs scheduling.  It intercepts job and job step status information to trigger other (successor) job in user's defined schedule flow.    In a networked z/OS and/or OS/390 hosts, Puspa capable to intercept job and job step status information on any host runs zJOS Agent.  This means, each scheduled job in Puspa can have predecessors and successors on any combined hosts.  Hence, users can define schedule crossing inter hosts in the network.

XDI/AutoXfer

  Package zJOS-XDI
Function Automatic spool files distribution
A set of service routines and JES2 SSI application to intercept each spool file occurrence on user's specified spool classes and manage FTP job to download it onto user's defined recipients.   Distribution mechanism is based on user's defined hierarchy of destinations and recipients.   Each recipient represents a targeted computer.

Platform z/OS, OS/390, JES2, TCP/IP
First released 2003
4 SSRF
  Package SSRF
Function VM-MVS Output management system
A set of VM and VM/GCS service routines, VM/VTAM and MVS/VTAM applications and JES2 SSI application to manage MVS spool files on JES2 spool and VSE spool files on VM spool.   Both set of spool files (on VM and MVS) are transfered user's defined recipients via SNA network.

Platform MVS/ESA, JES2, VM/XA, VTAM
First released 1990
5 SIOPAT
  Package SIOPAT
Function System and I/O performance analysis tools
A set of statistical analysis routines combined with RMF and VMAP report reader routines to analyze MVS and VM performance information.   It results system and I/O performance reports.  Besides, it provides interactive tool to estimate capacity growth and simulate some tuning actions.

VM/SPICO

  Package VM/SPICO
Function VM automated operation solution
A set of VM/CP and CMS service routines, VMCF and IUCV applications and VM/CMS nucleus extensions to intercept some system events (including all CMS users activities) to trigger user's defined set of actions.
