Are you preparing for IBM - MVS job interview?. MVS is Multiple Virtual Storage was one of the operating system commonly used on System/370 and 390 IBM computers. MVS supports very large virtual storage that is larger than available storage. MVS is the perfect solution for business problems that resulted from the need to run more applications. Job Control Language is the main user interface to MVS. Later on CICS and TSO, the interactive time sharing interface are used mainly to run development tools. TSO's basic interface is command line. MVS software recovery is used for problem debugging. Good knowledge on these concepts will fetch right job. Wisdomjobs framed IBM - MVS job interview questions and answers to make it easier for your interview preparation.
PDS can extend 15 time after it is allocated. PDSE can extend 122 times.
STEPS BEFORE MERGING?
DUMMY DATASET USES?
DIFFERENCES BETWEEN IDCAMS AND ICETOOLS?
DIFFERENCE BETWEEN ALL JCL UTILITY TOOLS?
dummy dataset means it dont have any control fields. so,we place a dummy
ex:SYSIN DD DUMMY(NO FUNCTION).
JCL UTILITY TOOLS:
IT IS USED TO CREATE,COPY OR PRINT SEQUENTIAL DATASETS.
I IS USED TO COPY NUMBERS OF PARTITIONED DATASETS.
THIS UTILITY IS CALLED DUMMY UTILITY ALSO BY USING THIS UTILITY WE CAN CREATE A DATASET.
16 - GPR
16 - Access Registers
16 - Control Registers
1 - Special Register called PSW
4 - floating-point Registers
To spool means "to operate (an input/output device) by using buffers in main and secondary storage." Not sure if there is any full form.
If you meant SDSF, it stands for sytem display and search facility.
A PDS or Partitioned Data Set is a dataset containing multiple members, each of which holds a separate sub-data set, similar to a directory in other types of file systems.
This type of dataset is often used to hold executable programs (load modules), source program libraries (especially Assembler macro definitions). A PDS is most somewhat analogous to a Zip file on microcomputers, except the files stored in a PDS are not compressed.
The Partitioned Data Set can only allocate on a single volume with the maximum size of 65536 tracks.
Besides members, a PDS consists also of their directory.
Each member can be accessed directly using the directory structure. Once a member is located, the data stored in that member is handled in the same manner as a PS (sequential) data set.
As in DIRECTORY we can store files as well as another DIRECTORY which includes other files but PDS includes only mebers not another PDS inside it
TYPE RECOVERYON on command prompt then UNDO command enable.
UNDO command is used to it rollbacks previous data.
SRCHFOR abc SRCHFORC xyz, (+5)
SRCHFOR 'abc' search for abc in the current PDS or LIBRARY.
SRCHFOR C 'xyz', (+5) search for 'xyz' and (+5) in continuation (i.e. in the same line only).
SMS in mainframe is Storage Management System. I hope it has nothing to do with telephone SMS.
Regarding the Storage Management System, I can say something soon.
You can create a new pds with file aid 3.2.
Here the question is, same structure of an existing pds. it is easy to note down the structure and type it again while allocating a daataset, but what is the shortest form of doing this is the question...
Panel name is ISPf/PDF primary option menu
Swap-in and Swap-out is the transfer of all valid pages between auxiliary storage to real storage and vice-versa.
Address space is the range of addresses in real storage.
The size of address space for 16 bit address space is 64kb
For s/370 the address space 21 bit- 16MB
For s370XA and EXA address space is 31 bit- 2GB
