achenlie is correct. If you have dropped to half-duplex it will be chronically slow. Just re-patching a cable can be enough to cause this issue when autonegotiation is in force. If you have the problem it may well be fixed by a total cold start where you bring up the network first, then the storage, then the servers.
Imho whether Jumbo Packets will cause or cure a performance issue depends on the network hardware.
To get an idea of scale, can your DBA post the contents of the following Oracle 9i system table along with how long the Oracle server had been up at the time:
This table includes i/o stats and other useful pointers such as counts of performance killers like disc sorts.
I wish to substituite a string on each line but ONLY if it appears within double-quotes:

I wish to change the "#" characters within the double quoted string to "_":

... but as you see, the "comment" hash... (2 Replies)
Hi All,
How does Solaris 9/10 alert the server? Where do you get the error on the server?
Is there some kind of verifying of errors (like in AIX, CERTIFY resources or diagnose)?
Please let me know.
Thanks,

Hi,
I have a script that calls an external program to perform some calculations and then I read with "grep" and "sed" values from the output files. I've noticed that performance of KSH93 degrades with every iteration. The output files are all the same size, so I don't understand why after the... (2 Replies)
Hi, say for example if there is high disk write IO in one disk (detected from NMON), how to we identify what processes is writing on that particular disk? (3 Replies)

Session::Store::Oracle(3) User Contributed Perl Documentation Session::Store::Oracle(3)NAME
Apache::Session::Store::Oracle - Store persistent data in a Oracle database
SYNOPSIS
use Apache::Session::Store::Oracle;
my $store = new Apache::Session::Store::Oracle;
$store->insert($ref);
$store->update($ref);
$store->materialize($ref);
$store->remove($ref);
DESCRIPTION
Apache::Session::Store::Oracle fulfills the storage interface of Apache::Session. Session data is stored in a Oracle database.
SCHEMA
To use this module, you will need at least these columns in a table called 'sessions':
id varchar2(32) # or however long your session IDs are.
a_session long
To create this schema, you can execute this command using the sqlplus program:
CREATE TABLE sessions (
id varchar2(32) not null primary key,
a_session long
);
If you use some other command, ensure that there is a unique index on the table's id column.
CONFIGURATION
The module must know what datasource, username, and password to use when connecting to the database. These values can be set using the
options hash (see Apache::Session documentation). The options are DataSource, UserName, and Password.
Example:
tie %hash, 'Apache::Session::Oracle', $id, {
DataSource => 'dbi:Oracle:database',
UserName => 'database_user',
Password => 'K00l'
};
Instead, you may pass in an already-opened DBI handle to your database.
tie %hash, 'Apache::Session::Oracle', $id, {
Handle => $dbh
};
The last option is LongReadLen, which specifies the maximum size of the session object. If not supplied, the default maximum size is 8 KB.
