Operating Systems Solaris Find memory usage for a process Post 303001775 by bakunin on Friday 11th of August 2017 04:10:36 AM

Notice that Oracle relies heavily on shared memory: in addition to listing all the processes for the database you need to issue a ipcs -m th display the shared memory segments and analyse what you get there.

I am no Oracle expert but i recall vaguely that any Oracle instance will allocate only a certain amount of memory for all its processes and this value is configurable. I am not sure, anyhow, if this value is the SGA, the PGA or whatever - check this with the DBAs, they should know. It might be easier to do this than to list and add and analyse some OS-output.

I hope this helps.

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.
