Can't connect through IPC

Hi,

One of our helpful sysadmins moved the file system Oracle was running on to a new disk and changed a whole bunch of file permissions. I've gotten the system so you can connect locally using the TCP connection as follows:

sqlplus scott_at_mymachine/tiger

But, the IPC connection is getting the message below. I know this is a problem with permissions on the shared memory segment (it's a Solaris machine), but don't know what I might do to fix it.

sqlplus scott/tiger

SQL*Plus: Release 8.0.3.0.0 - Production on Wed Aug 11 15:16:39 1999

ERROR:
ORA-01034: ORACLE not available
ORA-07320: smsget: shmat error when trying to attach sga. SVR4 Error: 13: Permission denied

I am able to connect to the database via either the oracle account or someone in the dba group, but I need this to work for all local system users.

Thanks,

• Tim
