hi quasar,
AS per your screenshot, your environment deals with IMS/DB.
use the below command to login ims db region :
LOGON APPLID=IMS81CR1
after logon give your credentials and then work with IMS commands.
From my knowledge i worked with few IMS commands.
sample for u: /DIS DB ALL
DATABASE TYPE TOTAL UNUSED TOTAL UNUSED ACC CONDITIONS
CIDB UP STOPPED, NOTOPEN, NOTINIT
DBFSAMD1 MSNR
DBFSAMD2 MSRF
DBFSAMD3 DEDB SEQ DEPEND DIRECT ADDRES UP NOTOPEN
CUSDB AREA N/A N/A N/A N/A NOTOPEN
DBFSAMD4 DL/I UP NOTOPEN, ALLOCS
DI21PART DL/I UP NOTOPEN
IVPDB1 DL/I UP NOTOPEN, ALLOCS
IVPDB1I DL/I UP NOTOPEN, ALLOCS
IVPDB2 DL/I UP NOTOPEN, ALLOCS

DFSIVD3A AREA N/A N/A N/A N/A NOTOPEN
