Mike,

There is an acb error code (2 or 4 bytes) that is useful. It used to be documented w/the VTAM OPEN as opposed to VSAM open. If I remember correctly it should be in the VTAM programming book(s). That will get you more detail.

All,

we currently move to another z/OS System (ADCD-based) and I have a poblem with one of our applications.

This dialog-application generates the 3270 Datastream itself and communicates to the 3270 terminals using a VTAM ACB.

I've configured this ACB as usual:

AMYAPP   VBUILD TYPE=APPL
MYAPP    APPL  APPC=YES,
               AUTH=(ACQ,PASS),
               MODETAB=LOGMODES,
               PARSESS=YES

(of couse, I've put the continuation char in column 72)


The command "D NET,IP=MYAPP,SCOPE=ALL" gives the following:

IST075I NAME = ADCD.MYAPP, TYPE = APPL
IST486I STATUS= CONCT, DESIRED STATE= CONCT
IST1447I REGISTRATION TYPE = CDSERVR
IST977I MDLTAB=***NA*** ASLTAB=***NA***
IST861I MODETAB=LOGMODES USSTAB=***NA*** LOGTAB=***NA***
IST934I DLOGMOD=***NA*** USS LANGTAB=***NA***
IST1632I VPACING =  8
IST1938I APPC = YES
IST597I CAPABILITY-PLU INHIBITED,SLU INHIBITED,SESSION LIMIT NONE
IST231I APPL MAJOR NODE = AMYAPP
IST654I I/O TRACE = OFF, BUFFER TRACE = OFF
IST1500I STATE TRACE = OFF
IST271I JOBNAME = ***NA***, STEPNAME = ***NA***, DSPNAME ***NA***
IST228I ENCRYPTION = OPTIONAL , TYPE = DES
IST1563I CKEYNAME = MYAPP CKEY = PRIMARY CERTIFY = NO
IST1552I MAC = NONE MACTYPE = NONE
IST1050I MAXIMUM COMPRESSION LEVEL - INPUT = 0, OUTPUT = 0
IST1633I ASRCVLM = 1000000
IST1634I DATA SPACE USAGE: CURRENT = ***NA*** MAXIMUM = ***NA***
IST171I ACTIVE SESSIONS = 0000000000, SESSION REQUESTS = 0000000000
IST172I NO SESSIONS EXIST
IST314I END


Now, when I tra to open the ACB in my assembler prog, I get the RC=8 in R15. This just says "ACB was not opened" - very helpful :-(

Any hints how to track this down? My VTAM Skills are very, very, very limited (I'm a Coder - not an VTAM-Admin)!


         OPEN  PACB
.......
PACB     ACB   AM=VTAM,APPLID=APPL1,EXLST=EXLST1,MACRF=LOGON
EXLST1   EXLST AM=VTAM,LOGON=LOGON1,SYNAD=SYNAD1,LERAD=LERAD1,
               RESP=RESP1,TPEND=TPEND1,LOSTERM=LOSTERM1,
               DFASY=DFASY1,NSEXIT=NSEXIT1,RELREQ=RELREQ1,SCIP=SCIP1
.....
APPL1       DC    X'08'
APPL1A      DC    CL8'MYAPP   '



Thank you very much for any hint!


Bye,
Michael
