Hi,
I'm new in IMS and I'm trying to learn. I'm using zOS ADCD 1.4. Does IMS have a master console to issue commands like "DIS DB ALL"? or are these commands issued in batch?
I would like to know the databases that are in the system and if there are any that I could use to write a simple program.
Thank you very much!

The IMS commands are issued thru the MVS console

Hi Enrico,
Thanks for your reply. If I issue "/DISPLAY", "DISPLAY" or "DIS DB ALL" in the MVS master console I get "COMMAND INVALID"
I also found that in the IMS Primer redbook on chapter 8, page 53 it talks about a primary and a secondary master console.
How can I find them?

the command D CONSOLES will tell,
anyway the console displaying the sequence of IPL messages will be the master console
did You check if the / is the proper char to send commands to your IMS subsystem

Ok, if I issue "D C" in the master console I get this:
D C
IEE889I 17.24.17 CONSOLE DISPLAY 407
MSG: CURR=2 LIM=1500 RPLY:CURR=1 LIM=10 SYS=P390 PFK=00
CONSOLE/ALT ID --------------- SPECIFICATIONS ---------------
SYSLOG COND=H AUTH=CMDS NBUF=0 UD=N
ROUTCDE=ALL
01/02 01 COND=M AUTH=MASTER NBUF=1 UD=Y
0700 AREA=Z,A MFORM=T,J
P390 DEL=RD RTME=1 RNUM=19 SEG=14 CON=N
USE=FC LEVEL=ALL PFKTAB=PFKTAB1
ROUTCDE=ALL
LOGON=OPTIONAL
MONITOR=JOBNAMES
I dont know how to determine the master consoles form that list. I also changed the variable CMDMCD to "Y" in the start proc and checked the CRC (Command Recognition Character) is "/".
Now every time I issue an IMS command like "/DIS DB ALL" I dont get the "COMMAND INVALID" like before but I dont see any output, nothing happens. Are the messages redirected somewhere else?
Thanks!

the output should bounce back on 0700,
the console where You entered the command

I get no response from any command, not even "/CHECKPOINT FREEZE" it seems like IMS is ignoring all commands I issue.
Is there any securitu option that might be causing this?
