VMS PIPE command

Post by tdirven » Thu Apr 02, 2020 11:59 am

Hi,

Why is this command not working. How can I correct it?

$ pipe sho sys/ima | sea sys$pipe java/wind=(2,2)
%SEARCH-F-RFAERR, RMS error using RFA access: RFA = 0, 0
-RMS-F-RAC, invalid record access mode

Without /window it works. But I would like to use /window option.

$ pipe sho sys/ima | sea sys$pipe java
DSA221:[JAVA605]JAVA$JAVA.EXE
DSA221:[JAVA605]JAVA$JAVA.EXE
DSA221:[JAVA605]JAVA$JAVA.EXE
DSA221:[JAVA605]JAVA$JAVA.EXE
DSA221:[java800.java$80.jre.bin]java.exe;1
DSA221:[JAVA605]JAVA$JAVA.EXE

The problem you're encountering is that a PIPE is a sequential device with no "memory" of prior data records that it has processed, and using /WINDOW in the SEARCH command requires an input file that can be processed with OpenVMS RMS library routines, thus allowing individual record access to allow it to move around in the file.

You can achieve your goal by creating a "real" output file instead of using the pipeline... something like this will probably work. (I don't have JAVA running, so I did a search on SERVER instead)

Code: Select all

$ pipe x="''f$unique()'.txt" ; show sys/image/out='x' ; search 'x' server/wind=(2,2) ; del 'x';*
