How much memory does the system have? How much swap space? Has the /etc/system file been updated with the required parameters for Oracle? How long has the problem been occuring? (and what changed when it started - more users, more databases, new searches being launched daily...)

This isn't something one of us can just say "Yea, you need more memory" You have to work with your Oracle DBA and IT team to find out what was happening and what is happening, know/investigate any changes happening on the system be it OS or Oracle.

Give more details of what you have found and possibly a 'best guess' can be given back.

Post output from any of the monitoring tools showing your problem. If you haven't been watching your servers or at least have sar running and collecting information, turn it on to have some clue of what the server is doing at what times. Check for new cron jobs, increase in users utilizing the database, changes in your volume management (if you are using Vertias or any other volume manager, losing a disk drive and having it 'automatically' place databases on different disks that had the space (but really could not handle the increased load of hits) could cause problems (if you didn't have hot spares).

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.
