Re: [ES40-developers] SCSI support for OpenVMS has arrived

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello all,

some news from Installation world :-)

The Openvms installation fails (40%) with a OpenVMS error (no errors  
in DOS console), maybe some memory error (???).

%PCSI-I-PRCOUTPUT, output from subprocess follows ...
%SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual  
address=000000000019E08C, PC=000000007FDC3BB4, PS=0000001B

%PCSI-E-MODREPLERR, error replacing module INSTALL in library  
DISK$ALPHASYS:[VMS$COMMON.][SYSLIB]DCLTABLES.EXE
-SYSTEM-F-ACCVIO, access violation, reason mask=!XB, virtual  
address=!XH, PC=!XH, PS=!XL
%PCSI-E-OPFAILED, operation failed
Terminating is strongly recommended. Do you want to terminate? [YES]

I replied "NO" :-) So I'll keep you in touch about the news...

regards,
fausto
