VSAM Refresher in 30 Minutes

[@mayurchawde3516]

I am not from the coding background but with the help of this tutorial I was able to understand many things ... great explination and not just a theory you are using actual mainframe enviroment to explain the things which is great and its very interactive as well

[@puneethhegdeable]

I have just become a fan of yours!!, It was indeed a refresher. I have close to 10 yrs of experience in Mainframes, but to gather the information or recall them quickly, then we need to refer or google,at times, so many things can be skipped or overlooked. But your video for me is complete. You will definitely get the fruits of your work. I wish you all the success brother in whatever you do in your life!!!

[@KumarITChannel]

Thank you! so much Puneeth for your kind words... Much Appreciated..

[@ritikasinha8139]

Thank you so much for putting this video out. It was PERFECT. In learning VSAM basics, I searched for supplemental videos. Your video's the BEST one because you repeatedly show how submitting impacts the output in Command Prompt. Plus, you explain in a way that a beginner can easily understand and connect dots. Thanks again!

[@KumarITChannel]

You're very welcome!

[@Santhosh-h9e]

Really I refreshed the VSAM concepts well after seeing your video. Thank you very much Sir!

[@slambro7923]

Huge fan of these videos. Currently in training for a job being a mainframe analyst, and watching these feels so much more accessible than sifting through pages of IBM documentation and Redbooks. Thank you!

[@KumarITChannel]

Happy to help!

[@mahimarathore2443]

I am watching your videos from a period of time now and I must say that this is the best source I have found so far to learn mainframes. You put across all the concepts with so ease. Thank you so much and you are amazing 🙌

In DB2 everything is in a table, but in vsam world everything is in vsam ksds? If I have a master ksds with the code as key and a field state, and a ksds with the names of the states (CO, COLORADO etc), is the right way to do so? Thank you!

[@anuishwarya6601]

This half an hour video was very much useful and easy to understand each very point similarly can u do for cobol as well or suggest a link for cobol practical as theortical specially editing options how it works

[@higiniofuentes2551]

Hi Kumar, in other os, the idea of separate files is replaced by using a db system. The use of tables in db2 is not more quick, flexible and take less space? Or is because there are a lot of these files and they need to be maintained? Thank you!

[@KumarITChannel]

DB2 uses a database management system, which allows a central storage of data that leads to mutipul user can access at a time & process the data . and another thing is Flexibility, DB2 is flexible and VSAM is not ? For Ex: what it would take to add an index to existing data. With DB2, you add the index, rebind the program, and DB2 will take advantage of it without having to change any application code. With VSAM, you would have to explicitly code requests to use the new index.

[@puspapalany3076]

Hi Mr. Kumar, I'm going to move from Operation work to System Programming job, May I know what are the topics i can study so that I can gain a basic understanding what are the SP's duty.

[@KumarITChannel]

Hello! Transitioning from Operations to System Programming (SP) in the mainframe world is an exciting shift. System Programmers play a pivotal role in the mainframe environment, ensuring the stability, efficiency, and evolution of the systems. Here are the primary topics and areas you should focus on to gain a basic understanding of the duties of a System Programmer: z/OS Overview: Familiarize yourself with the z/OS operating system, its architecture, and its components. Job Entry Subsystem (JES): Understand JES2 and JES3, their roles, job processing, job queues, and internal processes. Initialization and Tuning: Learn about system initialization parameters (IEASYSxx, IEFSSNxx) and how to tune them for system performance. Data Management: Dive into VSAM (Virtual Storage Access Method) - its types like KSDS, ESDS, and RRDS, and utilities like IDCAMS. and many more...

[@vindhyan2472]

Bro can you please tell me whether the below one is ESDS or RRDS: Associations Data------Treat.* 0 Data ----- treat.*.* I am confused..both esds RRDS looks same..how to identify the differences in listcat ?

[@KumarITChannel]

RRDS - You can read the records randomly and it has index ESDS - It's a sequential & mainly used in IMS, CICS & DB2

[@anandramasamy7251]

hi ..y cant you make vedio for abend codes for all cobol,jcl,db2,cics,sql like that.if u have already pls share the link..thank you!!

[@lucwijnen1508]

System abend-Codes can be found online in IBM's documentations ! What do you mean by JCL Abend-Code, this does not exist ! When an abend-code is a user abend (not system), then you must read the book of Abend-Codes from the related context, e.g. COBOL, CICS, DB2, etc... SQL codes are user-codes reported in the DB2 documentation.
