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
Jifty::DBI::Handle::Oracle - An oracle specific Handle object SYNOPSIS
DESCRIPTION
This module provides a subclass of Jifty::DBI::Handle that compensates for some of the idiosyncrasies of Oracle. METHODS
connect PARAMHASH: Driver, Database, Host, User, Password Takes a paramhash and connects to your DBI datasource. database_version Returns value of ORA_OCI constant, see "Constants" in DBD::Oracle. insert Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted. build_dsn PARAMHASH Takes a bunch of parameters: Required: Driver, Database or Host/SID, Optional: Port and RequireSSL Builds a dsn suitable for an Oracle DBI connection blob_params column_NAME column_type Returns a hash ref for the bind_param call to identify BLOB types used by the current database for a particular column type. The current Oracle implementation only supports ORA_CLOB types(112). apply_limits STATEMENTREF ROWS_PER_PAGE FIRST_ROW takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting with FIRST_ROW; distinct_query STATEMENTREF takes an incomplete SQL SELECT statement and massages it to return a DISTINCT result set.
