| Hello. I am building a new tech lpar, I have experience with z/OS but not so much with VTAM, TCPIP and TN3270. I am copying datasets from other lpars with appropriate modifications. I am able to start VTAM and TCPIP successfully and issue NETSTAT commands, etc. However, when I try to start TN3270, I get $HASP373 and $HASP395 saying it started and ended. No other messages. I am not able to FTP in to do FILEMODE=JES and get output. The port 23 is correctly allocated to TN3270 task. I have the terminals and application LU varied active in VTAM. Can anyone suggest a solution? Thank you in advance. Martin |

| What does the TCP/IP TN3270 parameter member look like? I'd start debugging by looking at that member. |

I tried to attach these to the post but couldn't figure out how yet, thank you. |

If TN3270 shuts down, how do you know this? What does a console command D TCPIP,TN3270 show? |

As I say, when I try to start TN3270 it starts and then ends. It does not stay active.
If I issue D TCPIP I get this:
2018121 12.40.30 TECH
EZAOP50I TCPIP STATUS REPORT 198
COUNT TCPIP NAME VERSION STATUS
----- ---------- -------- --------------------------------
1 TCPIP CS V1R13 ACTIVE
*** END TCPIP STATUS REPORT ***
(Notice I am on z/OS V1.13, back level, I know.)
S TN3270
$HASP373 TN3270 STARTED
$HASP395 TN3270 ENDED |

You may want to try the debugging as shown in www.ibm.com/support/knowledgecenter/SSQ2R2_9.1.1/com.ibm.ent.dbt.zos.doc/cgdita/tdeftcp1.html -- such as trying to set up to connect to a different port (the reference uses 2023), which hopefully will show up any problems with your current configuration. The fact that TN3270 starts and stops immediately indicates there's probably some configuration error.
Another possibility would be to use the Redbook IBM z/OS V1R13 Communications Server TCP/IP Implementation: Volume 2 Standard Applications (SG24-7997) section 2.7 to debug your configuration. It tells you to add DEBUG to a copy of your configuration so you can use console command V TCPIP,,OBEYFILE to turn debugging on and off for your TN3270. |

Can you try changing the LU names to different range
from
| Code: |
DEFAULTLUS
L00T0001..L00T0030
ENDDEFAULTLUS |
to
| Code: |
DEFAULTLUS
LXXT0001..LXXT0030
ENDDEFAULTLUS |
I remember facing similar issue when LU names were same between two lpars. Wouldn't hurt trying I guess. |

| Are there any error messages at all in the SYSLOG or TCPIP or TN3270 task? |

| Hello, thank you for your suggestions. I was finally able to logon, the problem with the TN3270 proc was the ACID did not have RACF access to read the SYS1.VTAM* (SYS1.VTAMLIB) concatenation in the TN3270 PROC STEPLIB. Shame on me! Thanks again, I am learning enough to now be dangerous. Marty |
