Oracle10g Express in Linux FC6 startup error...

[Joncamp]

I just installed Oracle10g Express on Linux FC6.

I get errors in Java and SQLPlus when trying to connect to the database, or start it.

In SQLPlus as "sysdba" when I type "startup" I get this error...
ORA-27100: shared memory realm already exists

And in Java or SQLPlus when I try to connect as a valid user I get this error...
ORA-01034: ORACLE not available
ORA-27123: unable to attach to shared memory segment

Please help me.

Hello,

welcome to Oracle forums at tek-tips!
But first of all let me tell you that there also is an Oracle 10g forum here. You might get faster and better help there. (Oracle 8 is a bit out of date; not sure how many members still have a look at here.)

But anyways, I think your question will have the same answer in all versions of Oracle.

27100, 00000, "shared memory realm already exists"
// *Cause: Tried to start duplicate instances, or tried to restart an
// instance that had not been properly shutdown
// *Action: Use a different instance name, or cleanup the failed instance's
// SGA

There may be better ways of of doing a cleanup the failed instance's SGA, but a server reboot should solve it.

hope this helps
