Hello,

I have the same problem running ORACLE7 Server Release 7.3.2.3 on DIGITAL 
UNIX 3.2G. Whenever I try to run sqlplus, I get the same error message:

1492.4check your instance firstALFAM7::GOSEJACOBTue Apr 22 1997 12:4731

    Maybe a stupid question but did you check that your instance is up and
    running and that your ORACLE_SID points to the right instance?
    
    Otherwise a message like:
    
        SQL*Plus: Release 3.3.2.0.0 - Production on Tue Apr 22 14:39:55 1997
    
        Copyright (c) Oracle Corporation 1979, 1994.  All rights reserved.
    
        ERROR: ORA-01034: ORACLE not available
        ORA-07429: smsgsg: shmget() failed to get segment.
        DEC OSF/1 (AXP) Error: 2: No such file or directory
    
    Is the 'normal' way of sqlplus telling you that your instance is not
    available when you try to connect to a local instance. Sooooo check
    the status of your instance first.
    
    BTW. usually 'oerr <facility> <error code>' provides you with some idea
    of what might be going wrong; e.g. try
    
    	oerr ora 1034
        oerr ora 7429
    
    Hope this helps

    Maybe, mabye not. You may have the same messages, but those specific
    messages can have a lot of different causes. So you may well have a
    completely different underlying problem.

> My system parameters are the following:
    :

    The system params are only really useful in conjuction with the ORACLE 
    SGA params that act on them. Still, that shm-max appears too low.
    
    good luck,
    		Hein.
