IPWIZARD errors after installing Release 6.4.0
The errors:
If you are trying to use the IPWIZARD utility to set up a basic TCP/IP system on a newly-installed 6.4.0 system that does not have APAR PI70089 installed, the IPWIZARD utility will hang with the following console messages:
DTCIPW2508I DTCIPWIZ EXEC is attempting to create the DTCIPW2508I necessary configuration files USER DSC LOGOFF AS TCPIP USERS = xx
Upon return to the IPWIZARD panel interface, the following message is erroneously reported:
DTCIPW2521E Insufficient virtual addresses available
If one inspects the TCPIP server console (present in the TCPMAINT virtual reader) after the failed IPWIZARD configuration attempt, this TCPRUN error message should be apparent:
DTCRUN1002E File TCPIP DATA * was not found on any accessed disk or directory
The circumvention:
Before attempting to use the IPWIZARD utility to configure basic TCP/IP settings for a newly-installed system, the following circumventive action is necessary:
a) Logon the TCPMAINT user ID b) Issue the command: query search - This command should produce a result similar to: TCM191 191 A R/W TCM198 198 D R/W TCM591 591 E R/W TCM592 592 F R/W MNT190 190 S R/O MNT19E 19E Y/S R/O - Make note of the file mode letter cited for the TCPMAINT 198 disk. For this example, this is 'D', as cited in this line of the response output TCM198 198 D R/W c) Issue the command: listfile tcpip sdata * - This command should produce a result similar to: TCPIP SDATA F2 - Make note of the file mode letter cited for this result (for this example, the file mode letter is 'F'). d) Use the listed TCPIP SDATA file to create a 'dummy' TCPIP DATA file on the TCPMAINT 198 disk. e) Issue the command: copyfile tcpip sdata f = data d (repl f) Logoff the TCPMAINT user ID
After the above action is completed, one can use the IPWIZARD utility as needed. After a working TCP/IP configuration is in place, one can log back on to the TCPMAINT userid and erase the 'dummy' TCPIP DATA file from the TCPMAINT 198 disk.
These circumventive actions are necessary to overcome a known issue with the TCPRUN EXEC file (supplied with the z/VM 6.4.0 system deliverable) which incorrectly requires a TCPIP DATA file to be present for TCP/IP server initialization.
This problem is corrected by APAR PI70089 (PTF UI42274 for Release 6.4.0).
