Enterprise Computing was introduced as one of the subjects in course curriculum with the

permission granted by Enterprise Computing University Relation Team , IBM, INDIA.

Enterprise Computing is being conducted as a part of MCA curriculum for 2-semesters.

Dr. E. Palayandi, former Head –in-charge, Dept. of Computer Centre (MCA) greeted Enterprise

Computing to be one of the subjects in the course curriculum in the year 2010.

Staff Members registered the username and password in the IBM Academic Initiative Membership.

This has helped the staff members to have continuous access to wealthy resources for academic

use, including IBM software, courseware, tutorials, discounts and much more amenities.

The WebEx training was successfully conducted in the MKU premises, which was organized by IBM.

MKU & MAINFRAME

IBM sent course materials and lab-oriented programs, assessment practice for JCL, Red Books,

ZOS : IBM System z Entry Level for z/OS Questions and Answers and slides to the department.

Mrs. Amala (In-charge, IBM Academic Initiative) discussed about the concepts such as ISPF, JCL, COBOL,

Db2, VSAM and CICS, in the first FACULTY ENABLEMENT WORKSHOP in our department.

KCTRADMIN (USA) issues an unique username and password for every student of each batch so that

the students can get a hands-on experience over the programming environment of IBM Mainframe.

Our lab is well- equipped with the latest technologies to match with the current IT trends. With the IBM

collaboration, we undergo lab sessions using Vista emulator to connect with KCTR server via Internet.

MKU & MAINFRAME
