I beg to differ. Normally, a wrong entry in the semaphore in the /etc/system file will cause the DB to be unable to start up.
If the error you see happens a couple of days after restarting the DB, most likely it is due to fragmentation shared pool.
These are the things you can try in order:
1) Check for SQL that are not using binding variable, get your developers to change them to binding variable. This will reduce the number of distinct SQLs required to be cached in the shared_pool.
2) Increase the shared_pool and reduce the shared_pool_reserved size. This will allow more distinct SQLs to be cached in shared_pool and at the same time, reduce the usage of shared_pool_reserved. (This will help if the fragmented shared pool you are facing is at the shared_pool_reserved)
3) Check Oracle metalink for bugs related to this oracle error. I do know that Oracle 9i has a bug related to this, not too sure on Oracle 8i.

dbix::class::storage::dbi::oracle::wherejoins
DBIx::Class::Storage::DBI::Oracle::WhereJoins(3) User Contributed Perl Documentation DBIx::Class::Storage::DBI::Oracle::WhereJoins(3)
NAME
DBIx::Class::Storage::DBI::Oracle::WhereJoins - Oracle joins in WHERE syntax support (instead of ANSI).
PURPOSE
This module is used with Oracle < 9.0 due to lack of support for standard ANSI join syntax.
SYNOPSIS
DBIx::Class should automagically detect Oracle and use this module with no work from you.
DESCRIPTION
This class implements Oracle's WhereJoin support. Instead of:
SELECT x FROM y JOIN z ON y.id = z.id
It will write:
SELECT x FROM y, z WHERE y.id = z.id
It should properly support left joins, and right joins. Full outer joins are not possible due to the fact that Oracle requires the entire
query be written to union the results of a left and right join, and by the time this module is called to create the where query and table
definition part of the SQL query, it's already too late.
METHODS
See DBIx::Class::SQLMaker::OracleJoins for implementation details.
BUGS
Does not support full outer joins. Probably lots more.
