I have an insert/update trigger for a Oracle table.
Is there a way to send the details of the affected row(all columns) as a message to JMS?
I can write a Java Program, 'loadjava' that and call from the trigger.
Does this way affect performance?
Is there any native way of achieving this?
There is indeed a native way: use AQ JMS from PL/SQL, see https://docs.oracle.com/database/121/ADQUE/jm_exmpl.htm#ADQUE1600. In short you create an AQ queue with a JMS payload type; then you can post messages with PL/SQL from the trigger. An external Java client can connect to the database and read the messages with JMS.
I don't know how much a call into Java would affect performance, but I try to avoid it. It was a nice idea but it never really caught on, so it remains a fringe case and at least early on there were always issues. PL/SQL on the other hand works.
If you need to send data to another message queue product (tags activemq and mq) you can read the messages in Java and forward them. It adds an extra step, but it is straightforward.
loadjava have many problems and not stable if there is many classes loaded and many business, take a look Calling Java from Oracle, PLSQL causing oracle.aurora.vm.ReadOnlyObjectException
Oracle AQ as i know is not free.
I have implemented the same need after trying many possibilities by creating only 1 class loaded to oracle with loadjava which is called as a procedure by a trigger and have the responsability to call an external java program with all needed parameters and log external process output to a table, as below.
i have encoded text mesage to BASE64 because i used JSON format and some specials caracters can causes problems as a parameters to external java program.
i have used "#*#jms_separator#*#" as a separator in the sent parameter string to parse the content if i need to send many parameters to the external program.
the whole duration of ShellExecutor.shellExec is around 500ms and running since 1 year without any problem.

I have a custom DB Appender which extends the logback DBAppender. My application has 100 parallel threads. These threads also log the events into database through the custom db appender while processing the requests.
The performance of the logback is so slow that with the logs disabled, the execution finishes in 20 mins. Whereas with the logs enabled, it takes almost 5 hours to finish most of the time waiting for the logs to be written to proceed to the next step as my logging is synchronous.
At first I thought the slow performance could be due to the synchronized doAppend method of logback appender. However, I later noticed that DB appender extends the
UnsynchronizedAppenderBase(public abstract class DBAppenderBase<E>
/* */ extends UnsynchronizedAppenderBase<E>).
Can anyone help me understand what could be the reason for this poor performance?

I'm implementing a load test scenario against a IBM MQ with Gatling.
The setup is basically the same as mentioned here
Problem: I'm not able to initialize the required ContextFactory with IBM MQ - which should be com.ibm.mq.jms.context.WMQInitialContextFactory.
The WMQInitialContextFactory cannot be found.
But my build.sbt is containing the IBM MQ dependency correctly (being successfully retrieved by our internal Nexus :
"com.ibm.mq" % "com.ibm.mq" % "8.0.0.3"
My gatling scenario:
package com.myawesomecompany.loadtest
import com.ibm.mq._
import com.ibm.mq.jms.MQConnectionFactory
import com.ibm.mq.jms.JMSMQ_Messages
import com.ibm.msg.client.wmq.common.CommonConstants
import io.gatling.core.Predef._
import io.gatling.core.scenario.Simulation
import io.gatling.jms.Predef._
import javax.jms._
import scala.concurrent.duration._
class JMSLoadTest extends Simulation {
val jmsConfiguration = jms
.connectionFactoryName("ConnectionFactory")
.url("devmq01.company.dmz")
.credentials("mqm", "mqm")
.contextFactory(classOf[com.ibm.mq.jms.context.WMQInitialContrextFactory].getName)
.listenerCount(1)
.usePersistentDeliveryMode
val scn = scenario("Load testing GPRSForwarder").repeat(1) {
exec(jms("testing GPRSForwarder...").reqreply
.queue("COMPANY.TEST.QUEUE")
.textMessage("00001404020611100E033102C20EBB51CC1C036EFFFF00010002323802000200FE05001400000000FFFFFFFFFFFFFFFFFF040010038B0D6912EB10CE070206110F37298C")
.jmsType("test_jms_type")
)
}
setUp(scn.inject(rampUsersPerSec(10) to 1000 during (2 minutes)))
.protocols(jmsConfiguration)
}
The setup is equivalent to this one - but instead of using ActiveMQInitalContextFactory, I'm forced to use the "counterpart" of IBM MQ.
According to official docks the WMQInitialContextFactory should be in com.ibm.mq.jms.context but it is not. Ore is there some constant in CommonConstants which I can use to initialize a ContextFactory ?
Thanks a lot in advance.
Problem: I'm not able to initialize the required ContextFactory with
IBM MQ - which should be
com.ibm.mq.jms.context.WMQInitialContextFactory. The
WMQInitialContextFactory cannot be found.
Do not use WMQInitialContextFactory. It was an MQ SupportPac someone created where they wanted to use MQ as the JNDI repository. It is not a good idea plus the SupportPac does not support any form of security (i.e. SSL/TLS or security exit).
You should use a file based MQ JNDI. Here's a basic example:

Not directly related to your problem, but JMSToolBox with its scripting feature, is a tool that allows to perform bulk/load test on IBM MQ.
With it you can define a script, composed of steps, that will read a template with variable placeholders and repeatedly put messages in one or multiple destinations. It can also directly read saved messages from a directory etc.
You can download it from SourceForge here
Documentation of the script feature is here

i have used httppost to send and retrive the data from the site.but when i run the program i m not getting the required data
i want to pass the s1 and s2 paramters to the htp post method.but i m nt getting how to do it
You have your parameters as the params in your doInBackground method here String... params. So you can use them like this:
protected String doInBackground(String... params) {
s1=params[0];
s2=params[1];
//...
}
Instead of:
protected String doInBackground(String... params) {
s1=un.getText().toString();
s2=pw.getText().toString();
//...
}
Trying to compress the image using JAI with TIFF format. It works fine on Windows XP, But it produces 10 times bigger size file on Windows 7 compared to Windows XP.
Using JAI 1.1 and JRE 1.6_0_16
What might be the issue? Appreciate your assistance.
