Tracing ORA-01427

To Trace Oracle error ORA-01427


SQL> alter system set events '1427 trace name ERRORSTACK level 10';


After the error occurs, see the trace generated in the udump directory.

Testing on 15 Dec 2010, now sql that caused the error, is listed on trace file.

Stats Pack or AWR

Since none of my databases are Enterprice Licenced, I dont get to use AWR year on year.
So hence alwasy foget the AWR command, still surviving with the stats pack command.

Here's one that I need remember:


@?/rdbms/admin/awrrpt.sql


Munin 10+ cpu patch

for 10 or cpu box:


please login to lnx-db28.nid as root.

vi /usr/share/munin/plugins/cpu

search for NCPU

remove a space e.g.

From

NCPU=`expr \`grep '^cpu. ' /proc/stat | wc -l\` - 1`


To (Only removing the space after cpu.)

NCPU=`expr \`grep '^cpu.' /proc/stat | wc -l\` - 1`


Restart munin node on that box

/etc/init.d/munin-node restart

Found below link very useful:

Keeing a copy here, in case the orginal is moved or broken.


==============
Discount Fixed
==============

Step 1: Create a new button for the main screen.

Login as Admin and goto maintainence --> resources and add the following line to "Ticket.Buttons"

< button key="button.discount" name="button.discount" code="Code.Discount" />


Step 2: Create a new resource called "Code.Discount" and add the follwing code to it.

import com.openbravo.format.Formats;
import com.openbravo.pos.ticket.TicketLineInfo;
import com.openbravo.pos.ticket.TicketProductInfo;

discountamount = sales.getInputValue();

index = sales.getSelectedIndex();
if (index >= 0) {
line = ticket.getLine(index);
if (line.getPrice() > 0.0 && discountamount > 0.0) {

sdiscount = Formats.CURRENCY.formatValue(discountamount);

ticket.insertLine(index + 1,
new TicketLineInfo(
"Discount " + sdiscount,
line.getProductTaxCategoryID(),
line.getMultiply(),
-discountamount,
line.getTaxInfo()));
sales.setSelectedIndex(index + 1);
} else {
java.awt.Toolkit.getDefaultToolkit().beep();
}
} else {
java.awt.Toolkit.getDefaultToolkit().beep();
}


Step 3: Add permission to who all can use this function.

Either Administrator, Manager or Employees etc...

The following line will be added to maintainence ==> roles.


< class name="button.discount" />


Restart your POS and goto sales screen to check out your new button........ Viola


I would add one more step:

add following line in the pos_messages.properties located in Locales folder so a proper label on the button is placed.


button.discount=Discount



==================
Discount Percentag
==================

Here is the code for a user entered discount percentage rate.

Pros: You can enter discount amount. i.e. 10% of total ticket entered as 10

20% of total ticket entered as 20 and so on

Cons: You can not remove the discount once entered. ( can anyone point me how to add this exception as it gives out a strange error )



Input this code in a new resource called "discount.Total"



// % Discount for the total of the receipt

import com.openbravo.format.Formats;
import com.openbravo.pos.ticket.TicketLineInfo;
import com.openbravo.pos.ticket.TicketProductInfo;
import java.util.Properties;

discountperc = JOptionPane.showInputDialog(null, "Input percentage.....");
double discountrate = Double.parseDouble(discountperc);
discountrate = discountrate/100.00;

total = ticket.getTotal();
if (total > 0.0) {
sdiscount = Formats.PERCENT.formatValue(discountrate);

taxes = ticket.getTaxLines();
for (int i = 0; i < taxes.length; i++) {
taxline = taxes[i];
ticket.insertLine(ticket.getLinesCount(),
new TicketLineInfo(
"Discount " + sdiscount + " of " + taxline.printSubTotal(),
taxline.getTaxInfo().getTaxCategoryID(),
1.0,
-taxline.getSubTotal() * discountrate,
taxline.getTaxInfo()));
}
sales.setSelectedIndex(ticket.getLinesCount() - 1);
} else {
java.awt.Toolkit.getDefaultToolkit().beep();
}


now create a new button in "Ticket.Buttons"


< button key="button.discount" name="button.discount" code="discount.Total" />


and also add the permission in maintenance -> roles


< class name="button.discount" />
