Hi All,
Can anyone help me with the rexx command to list the active DB2 subsystem's running on mainframe box(To which I'm connected to).
Your help is highly appreciated.
Thanks

Your requirement is a bit vague, but why do you want to do it in Rexx?
How about batch SDSF, for example? |

I'm working on automation of few db2 job based on few user input and it is in Rexx using user interaction. So only need in Rexx.
If in batch how can we do it?
Thanks

Look up the Rexx language reference and you will see that there is no such Rexx 'command'. (Rexx does not have commands - like any other language it has keywords and functions.)
Look in the SQL Language Reference and in particular the Rexx section and you may find something. However, SDSF is probably the better bet so read the about the SDSF/Rexx interface - I guess it will be in the SDSF manuals. |

| If you don't have access to console commands, then you can use the SDSF/Rexx interface (ISFEXEC) to return the results of an SDSF 'DA' command. This will give you a list of all of the tasks running in the system and from there you can figure out which of them are for the DB2 subsystems currently active. (That of course assumes that you have access to the SDSF 'DA' command. I have worked in shops where it wasn't permitted.) |

I've slightly modified a routine of Peter Nancollis called DB2ERLY.
This routines loops through all active tasks and checks whether DSNZPARS is loaded. This approach may not work the most elegant way but does the job.
| Code: |
/* rexx */
numeric digits 10
cvt=ptr(76)
jesct=ptr(cvt+296)
sscvt=ptr(jesct+24)
do until sscvt = 0
db2ssid = stg(sscvt+8,4)
call getcsects
sscvt=ptr(sscvt+4)
end
exit
getcsects:
if sscvt = 0 then return
erlyprhb=ptr(sscvt+20)
if length(erlyprhb) > 9 then return
erlyeepl=ptr(erlyprhb+76)
eeplents = stg(erlyeepl+8,2)
eeplcent=erlyeepl+32
found = 0
do i = 1 to c2d(eeplents) - 1 until found = 1
if stg(eeplcent+4,8) = 'DSNZPARS' then found = 1
if stg(eeplcent+4,3) <> 'DSN' then leave
eeplcent=eeplcent+32
end
if found then say db2ssid
return
ptr:
return c2d(storage(d2x(arg(1)),4))
stg:
return storage(d2x(arg(1)),arg(2)) |
Give it a try |

Thankyou very much for valuable replies.
I'm able to get the list of active db2 subsystems using code provided by Stefan.
Thanks alot Stefan. |

Here I see only one issue, that in a sysplex environment.
For ex:-
3 DB2 subsystem is defined on one L-par in which 2 are not datasharing
and
1 DB2 subsystem is defined on the other L-Par which is datasharing.
If we run the code on second L-Par , we are getting the complete list of subsystem(which are on the first L-Par also).
Looking around if we can get the list of DB2 subsystem which are active/defined on the specific L-par on we are running this code.
Thanks

You can combine this code of Stefan with REXX /SDSF interface as suggested by Don .
List active tasks with SDSF DA command , and compare it with list of DB2 this way you can build a list of DB2 active on particular Lpar .
Hope this helps .
Regards,
MJ |
