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:

Select all

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!

Select all

AUTH=MASTER

should hint something

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?
