This might interest some of you. Listed below are the Mainframe Interview Questions for 3-5 Years Experience: Database and SQL Describe different transaction isolation levels in DB2 and their implications. What SQL statements have you used extensively during development and support? Explain the effe...

As far as I know, there isn't a single, definitive way to pinpoint the exact moment a DB2 database was switched to read-only (RO) status. However, there are several methods that can help you narrow down the timeframe: 1. DB2 Logs: Check the DB2 diagnostic log files (db2diag.log and others) for relev...

1. File Organization: Ensure the VSAM file is a  KSDS (Key Sequenced Data Set) , as this organization allows for direct access based on keys. 2. File Definition: Define the file in your COBOL program, matching the file's structure and key field: COBOL FD VSAM-FILE RECORDING MODE IS V ACCESS MODE IS...

When you are binding a COBOL program that calls external functions like JNI_CreateJavaVM (Java Native Interface) from a shared library or DLL (Dynamic Link Library), you need to provide the necessary information for the linker to resolve these external names. This typically involves specifying the l...

Calling Java from COBOL on z/OS using JNI involves several steps. Below is a high-level outline of the process, and I'll also provide a simple example: Write the Java Class: Create a simple Java class that you want to call from COBOL. Save it as a .java file. For example: // HelloWorld.java public c...

To have access to the JNI source file located in the z/OS UNIX System Services (USS) file system at /usr/lpp/cobol/include, you need to mount the USS file system that corresponds to the path /usr/lpp/cobol. In z/OS, USS file systems are typically mounted under the /u directory. Therefore, you should...

There is a good possibility that they might not call you back in near future, however, as you've not to join them, so they should not block you from joining them in future. Good luck with your career.

That statement can be applied, possibly, to any career choice and not just mainframes, yes? Let me add my thoughts to this: It can be safely assumed that when computer started and at the same time when some companies had enough money to deploy such "machines" back then, only choice about c...

Hi inderkumar,

What Microsoft Learning Partner program has to do with this thread, please share your perspective.

Would you mind giving more example and explanation over it. It's not my area however with more information, it might help.

Salaries are very subjective - though a bit of home work should pay. Check what other skill-set along with mainframes you can learn, try them. Start working on some projects and apply along with mainframe - lately during 2020, salaries for mainframe programmers have seen a surge as well. You might b...

What error do you get? Could you share more details?

I am not sure if 'browse by file-aid' creates a Job in background but your system team can set the priorities to cancel anything of this nature for production job execution. This is a pretty common scenario and I've not it happens in shops where I have been to.

LOL - can easily relate to that and how true is that.

Look at Twitter saga. What do you think Elon Musk has done it the right way? I know this is not that forum, however, this just not ethical at all, IMHO.

10 hours, at least. I think it our screen should be less but in this IT world I doubt it's going to decrease.

I'm rather concerned for my daughter, she is on screen all the time for her online classes and so-called homework thereafter.

Are they not just two different things? Why do you want to compare them?

I don't understand such interview questions, even if you by some magic are able to do it, what difference does this make to your office-life? How's is this relevant for an interviewing process?

Robert is one of the most knowledgeable person around on this website. It's really great reading your views Robert. Appreciate sharing that with us.

Respect,
