Top Forums UNIX for Advanced & Expert Users Shared memory shortage but lots of unused memory Post 56870 by rhfrommn on Wednesday 13th of October 2004 05:10:52 PM

I can't help you with the specific kernel parameter since I don't know HPUX very well. You'll have to ask your DBA or look it up.

But, I think I know what is going on. Oracle sets its shared memory area when it starts up. Even if it looks to the OS like there is 5GB free, if you take any of it which Oracle expected to be able to use Oracle will complain. If you are setting aside some memory for caching as you described, you probably have to decrease the shared global area in Oracle to compensate.

Hope that helped, I know it wasn't long on details . . .

Shared memory for shared library

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability. Obviously, I'll have to worry about mutual exclusion. (0 Replies)

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.
