About solaris memory management, you can read whatever has been written by Richard Mc Dougall.
About Oracle memory management, you can read whatever has been written by a member of tha "oak table" (Tom Kyte, Jonathan Lewis, Tanel Poder...)
Still regarding oracle : read about PGA automatic Tuning (from 9i i guess) as well as SGA automatique Tuning (from 10g i guess) (get info about how to set parameters sga_target, pga_aggregate_target, workarea_policy...)
Read also the concept guide Oracle as well as the Oracle Tuning guide of the version you are running.
make sur you have not exceeded the number of process/sessions (see gv$resource_limit view)
make your your system is correctly sized (semmns semmni etc... solaris parameter should be sized accordingly with the oracle instance it hosts (see Oracle Recommandation).
If you run Oracle in a local zone on solaris 10 then make sure you have a very recent patch update (Solaris 10 (8/07)) because the proc_lock_memory privilege (check with ppriv -v <pid>) has been added by default in the non-global zone so you can take advantage of the dism (Dynamic Intimate Shared Memory).

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. SEE ALSO
