Mainframe, MVS and zOS Discussion

Hi,

Can someone please explain in simple terms, what is the function of DBCTL? I did not answer this question.

what happened when You googled with "DBCTL" ?

It is used to access IMS files for CICS Transactions and it is an address space. The DBCTL region is like the IMS Transaction Manager without the support for terminals or message queues. The DBCTL environment has only IMS DB installed. The processing goals of the DBCTL environment are to:

• Process network transactions without IMS TM; that is, use IMS DB with a different transaction management subsystem, such as CICS.
• Run batch application programs to update databases at certain intervals (for example, process a payroll or produce an inventory report).
• Run database utilities using batch.

Please have a look at this link for more detail: https://www.ibm.com/support/knowledgece ... ctlenviron


This is pretty broad question for an interview, I believe.
