Mainframe Training Overview:
This bootcamp is a lecture and hands-on workshop course.
Participants learn and will demonstrate practical programming skills required to function as an entry-level programmer in an IBM Mainframe COBOL environment.
The use of structured COBOL design and coding techniques are emphasized throughout the class. Common mainframe programming scenarios and problems are presented and reinforced through a series of hands-on workshop problems.
Access to a working z/OS via TSO/ISPF system is required for student workshop sessions. Students should be ready and willing to devote some extra time before and after class hours to completing workshop problems.
Company standards and coding conventions can be added to this class as needed. Review of company "best" programs can be reviewed to show the "best that programs can be".
Each day will begin with a review of important topics from the previous day or 2.
This bootcamp training provides the fundamental, essential skills to function as an IBM mainframe COBOL entry-level programmer.
Additional training will be required for specific skill areas of mainframe processing based on the position the participant will be assuming.
This course provides a brief overview of VSAM, DB2 and CICS. Students will require specific training in these areas in order to acquires the skills necessary to utilize them effectively in a role as Application Developer. Participants will benefit from follow up training in I.T. soft skills and a more in-depth presentation of some topics.
Please refer to the schedule below for a general sequence of topics. Due to the nature of this class students must attend entire session. (i.e. They cannot drop in for only week 1 or week 2). The most effective manner in which to schedule the training is in one continuous 10 day block, a break may be inserted between weeks 1 and 2. If breaks are inserted between any weeks, it is suggested the break be no longer than 10 days.
Mainframe Training Audience:
New programmers with little or no mainframe programming experience who require knowledge and skills of an entry-level programmer in the IBM Enterprise COBOL, mainframe environment.
