ORA-01034, ORA-27101 and Linux errors on Fedora Core 2
I have been trying for days to get Oracle 10g up and running on Fedora
Core 2. I have followed Werner's directions exactly, but keep
receiving the following errors when I log into SQL*Plus. I have tried
all the solutions on your Web site.
[oracle@internal bin]$ ./sqlplus
SQL*Plus: Release 10.1.0.2.0 - Production on Mon Jul 12 22:45:24 2004

Enter user-name: SYS
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux Error: 2: No such file or directory
Make sure that you have set the ORACLE_SID and exported it in your
environment. If your instance is up and running, then you likely have enough
shared memory and semaphore resources. I know Werner's instructions include
information about setting up the proper kernel parameters, so if you followed
those instructions, you should already have things set up right. If you're
attempting to start the instance, you should connect like this:
sqlplus '/ as sysdba'
and hopefully things will go better -- or at least your error will change!
