DB2 - Determine Cost Savings in USD - After performance Tuning
Dear Team
Have this interesting question on how to determine cost savings(USD) based on performance tuning in Db2
I am using DB2 v10.5 . I worked on db2 procedure that loaded 20Million records in just 2 Mins.
ETL execution time reduced from 30 Mins to 2 Mins.
From 15 Hrs Monthly to 1 Hr
From 180 Hrs Yearly to 12 Hrs
So how should we calculate (180-12)=168 Hrs savings in-terms of cost savings in USD.
Should we refer Cost estimate during previous/updated query or any other way .
Please guide

Dear all,
I have a Local zone , where users feel that performance is not good.
Is it wise to collect the inputs from the local zone rather than taking from the global zone.
And also Can I tune from Global zone , so that it will reflect in local zone.

db2_pclose
DB2_PCLOSE(3) 1 DB2_PCLOSE(3)
db2_pclose - Closes a persistent database connection
SYNOPSIS
bool db2_pclose (resource $resource)
DESCRIPTION
This function closes a DB2 client connection created with db2_pconnect(3) and returns the corresponding resources to the database server.
Note
This function is only available on i5/OS in response to i5/OS system administration requests.
If you have a persistent DB2 client connection created with db2_pconnect(3), you may use this function to close the connection. To avoid
substantial connection performance penalties, this function should only be used in rare cases when the persistent connection has become
unresponsive or the persistent connection will not be needed for a long period of time.
PARAMETERS
o $connection
- Specifies an active DB2 client connection.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Closing a persistent connection
The following example demonstrates a successful attempt to close a connection to an IBM DB2 i5/OS database.
<?php
$conn = db2_pconnect('', '', '');
$rc = db2_pclose($conn);
if ($rc) {
echo "Connection was successfully closed.";
}
?>
The above example will output:
Connection was successfully closed.
