I have an M5K with disk issues I'm trying to troubleshoot, and it's causing me some confusion. I know the host has four on-board HDDs, but the format command's output shows c0t0d0, c0t1d0, c3t0d0, and c3t1d0. cfgadm -al shows c0t3d0 as the DVD-ROM drive, and c1 and c2 as SAN disks. Confused yet?

I think it is really great that you can try out a SunFire server for 60 days, risk free.

LEARN ABOUT PHP
oci_set_client_info
OCI_SET_CLIENT_INFO(3) OCI_SET_CLIENT_INFO(3)
oci_set_client_info - Sets the client information
SYNOPSIS
bool oci_set_client_info (resource $connection, string $client_info)
DESCRIPTION
Sets the client information for Oracle tracing.
The client information is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL
statement is executed.
The client information can subsequently be queried from database administration views such as V$SESSION.
The value may be retained across persistent connections.
PARAMETERS
o $connection
-An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).
o $client_info
- User chosen string up to 64 bytes long.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Setting the client information
<?php
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the client information
oci_set_client_info($c, 'My Application Version 2');
// Code that causes a roundtrip, for example a query:
$s = oci_parse($c, 'select * from dual');
oci_execute($s);
oci_fetch_all($s, $res);
sleep(30);
?>
// While the script is running, the administrator can see the client
// information:
sqlplus system/welcome
SQL> select client_info from v$session;
NOTES
Note
Oracle version requirement
This function is available when PHP is linked with Oracle Database libraries from version 10 g onwards.
Tip
Performance
With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO pack-
age. This is less efficient than using oci_set_client_info(3).
Caution
Roundtrip Gotcha
Some but not all OCI8 functions cause roundtrips. Roundtrips to the database may not occur with queries when result caching is
enabled.
