Dont agree anything verbally,like that they will replace this next day or so.if you are casual they will not turn up. Make it written and signed by the executive atleast  in the job card. Dont take the old/damaged parts ...leave it in the service center itself if possible. Finally dont sign any papers given by them post servicing, also dont pay the bill till it got repaired/replaced. Give appropriate feedback based on your experience post servicing. For complaints There will be a GM associated with every dealers, give a written complaint,and lastly write to the company stating the issue.

Some times during development we used to get out of memory error if we try to view/modify the Dynamo AdminUI/Component Browser(through http://host:port/dyn/admin ) , this happens eventhough we had made the necessary settings for JVM parameters (MEM_ARGS and MaxPermSize) A work around for this issue is to just type the absoulute path of the component in the address bar For eg: if  you need to view/modify  the component, DeploymentServer through the component browser,g o to the Dynamo AdminUI/Component Browser,Browse to the path, http://host:port/dyn/admin/nucleus/atg/epub/DeploymentServer/ You can view/modify the component now!!!

Initiate the transfer formalities in the new location/branch Go to the gas agency,with the below mentioned documents New Transfer Voucher also called subscription Voucher Regulator Book ID proof Address Proof Electricity bill Within 2 minutes the authorities can initiate the gas connection to your new location. Additionally you need to provide your date of birth and mobile numbers  to update in their system,mobile number is very important, Booking can be done through this only, also  in some agency  you have to send sms through the registered mobile numbers for booking. Note: You have the luxury to give an alternate number which would be useful in certain circumstances,the authorities generally are ignorant and will not tell  anything about this,but  this can be helpful in future. See how can we initiate  Transfer Formalities in Old Branch

Initiate the transfer formalities in the old/current location/branch  Go to the gas agency,with the below mentioned documents Transfer Voucher also called subscription Voucher Regulator Book ID proof You have to enquire well before the location and agency to which you need to initaiate the transfer Within 2 minutes the authorities can initiate the transfer to your preferred location. You have to do a signature in the new Transfer Voucher/Subscription Voucher. That’s all you have to do !!! Note: You don’t have to surrender any cylinder,regulator or any things that you are currently using. See how to Initiate the  Transfer Formalities in New Branch

I encountered this issue while trying to run an ear module  from our application, the console logs are given below After researching a while,it seems that we need to add a specific permission,'modifyThread' in the java policy file if its not there. I had tweaked the java.policy file(location - jdk_xxx->jre->lib->security->java.policy) and added the below entry Be sure to take a back up of your policy file before doing  such changes,as there are chances your original file may get corrupt if something goes wrong. Now restart your Server and load your application, This solved the issue !!! if anybody has other thoughts,please share it here. Next tip

Console Log: In Weblogic Server Console logs we are getting the exception which says access is denied with the AccessControlException. This exception occurs when both the weblogic server and ACC is running  and we try to shutdown the weblogic server via shutdown scripts .The reason being the ATG control center is  running in some ther ports being initiated by the weblogic thread. To resolve the issue you have to tweak the weblogic policy file bea/wlserver_XX/server/lib/weblogic.policy file Add the below entry grant { permission javax.management.MBeanPermission "*", "*"; Now restart your Server and ACC to verify.Ideally this will resolve the issue !!! Next tip

XAConnection java.sql.SQLException Logs: /atg/dynamo/messaging/SqlJmsProvider    ---     java.sql.SQLException: Unexpected exception while enlisting XAConnection java.sql.SQLException: XA error: XAResource.XAER_NOTA start() failed on resource 'XXX_DS': XAER_NOTA : The XID is not valid. Fix: Tweak the configuration file of weblogic server and add an entry after the datasource params. jdbc-xa-params> <xa-set-transaction-timeout>true</xa-set-transaction-timeout> </jdbc-xa-params> Make sure you are taking backup of the original configuration file,chances are there while doing modification you may accidently corrupt the orignial file.After doing the necesary changes bounce the Server once,to verify the issue. Still if you are encountering the issue you have to increase the jta values.refer the section to do so Next tip

PermGen or Permanent Generation space is a part of Heap where it stores the Class definitions.By default JVM will take the value as 32m,if we have not set this explicitly,so this is comparitively very less. the issue stated here points that there is no enough Perm Gen space avaialable as per your current JVM settings,so increase it to avoid this issue.Again you need to select appropriate values based on your  development environment,how much hardware support etc. You need to modify this in any webLogic startup Script,i had modified this in setDomain.env file. Increase the heap size to MEM_ARGS=-Xms _ _ _ m -Xmx _ _ _ _ , here i have given values as 512 and 1024 respectievly. Set the Perm size MaxPermSize=_ _ _m,the value given here is 512 . Ideally the Max PermGen value allocated to JVM will be 50% of the Max Heap Size(Xmx). Also typically in a development environment ,if you are using one Admin Server to manage multiple Managed Servers and all your appli...

Java Transaction Timeout Issues We need to basically moidfy the transaction timeout parameter which by default is set as 30seconds by weblogic, many requests might  get timedout  between this very short period,so depends upon your requirement choose the best value that works for your development environment.I had modified it to 600. Two way you can achive this. one is again tweaking the configuratin file and another way to modify it through the admin console. Increase the transaction timeout seconds through console( Services->JTA),or modify in config.xml. If you are modifying the configuration file make sure to take  a backup copy,restart the server,ideally you may not further experience this issue.   Next tip

Avoid NullPointer Exception due to ATG caching of request attributes If you are following best practices while developing ATG applications,you have to be careful enough to avoid any nullpointer exception which crops up during ATG caching of request attributes. The solution  is pretty straight forward,you have to tweak your weblogic configuraion file a bit to add the entry like below. Set  the keep-alive-enabled property to false, in your config.xml. Make sure to take a backup of your original config.xml and restart the server to reflect these modifications. Next tip

For Running ACC in seperate VM ,you will experience some issues related to  authorisation,users with DAS are not impacted by this. So if you are using weblogic server there is an easy fix for this,you have to tweak your configuration file and add an entry to resolve this issue, below is the modification you have to do in your config.xml file. Take a backup copy of your original configuration file,this will save you once the original file is corrupted.restart the server,start your ACC in seperate VM from the component browser/adminUI,ideally you may not experience this issue further.

I encountered a strange issue while trying to execute build tasks through Ant tool,this is related to the java target. i got an exception 'NoClassDefFoundError’,it seems to an error in one of the classes in sun.reflect package,i have no clue on how to fix this error,but after doing some research ,i came to know that its always the best practice to run the Java code in a seperate JVM,To achieve this Ant tool has provided you a parameter named ' fork ',which upon setting as 'true' has solved the issue !!!  <java classname="xxxxx" fork="true"> Basically this will use a new JVM to run the code,thereby reducing the chances of running out of memory  issues too. you can verify how to  Suppress warnings in Ant Next tip  

I have experienced an issue,while trying to access the application running in  a remote machine, i was getting a 'connection refused' message,and not able to load the application pages further. Environment ATG 9.1 Weblogic10.0. I faced this issue while accessing the web application remotely on another machine through http protocol Upon further analysis,found the root cause,and that was due to an entry in the config.xml file which is none other than the listen address property   which is added as  'localhost' by default by the weblogic configuration. I deleted this entry and its working fine now !!! <listen-address>localhost</listen-address> Next tip

Suppressing Ant Warnings After Switching to  Jdk1.5 ,end up in seeing lot of ant warnings,some of the warnings  are too generic,like the one listed below. " warning: non-varargs call of varargs method with inexact argument type  for last parameter; [javac] cast to java.lang.Object for a varargs call". For me a bunch of warning like this makes no sense other than eating my entire console. So i decided to suppress these warnings. If you also want to get rid of these warnings, Add the attribute nowarn="on" to the  javac task in our build files. <javac fork="yes" destdir="${dir.java.bin}" debug="true" deprecation="false" optimize="off"   nowarn="on" > You will not be seeing the warning  next time !!! NoClassDefFoundError   while using Ant. Next tip

java.net.MalformedURLException . cannot understand  protocol "dynamosystemresource" Solution: Add protocol.jar to the Classpath,you can add an entry inside the Weblogic Startup Script (c:\bea\user_projects\domains\your_domain\bin\startWebLogic.cmd). set CLASSPATH=% SAVE_CLASSPATH%;c:\bea\user_projects\domains\your_domain\protocol.jar. then copy the protocol.jar file from C:\ATG\ATG9.1\DAS\lib\protocol.jar  to lib directory of your weblogic domain folder.Basically this jar file s hould be in the classpath of your application server. One occurrance of this issue is due to the creation of weblogic domain  after ATG Installation,because generally during the Installation  ATG installer will take care  of all the above steps.so in that case you can ignore this . Finally Restart your Server.Ideally this will solve  the issue.Good Luck.  Next tip

Since you know all component in ATG defaultly send their log events to a single logQueue component,we might need to customize log formats which best suits for our own components. For formatting log messages for your own components,there were two OOTB classes provided by ATG atg.service.datacollection.FormattingFileLogger   and atg.service.datacollection.FormattingConsoleLogger you can create your own logger components   by creating the component(properties) for the class FormattingFileLogger/FormattingConsoleLogger. Example #/xxx/xxx/xxx/xxx/xxxFormattingFileLogger $class=atg.service.datacollection.FormattingFileLogger $scope=global # directory and file name logFileDir=logs/application_logging logFileName=myApp_ formatFields= '<',dateTimeStamp:d/MMM/yyyy:H:mm:ss,'>',' [',sessionID,'] ',browserID,'"',comma,'IP="',ipAddress,'"' similar way you can create the Console Logger ...

For getting Refund through Efiling I have not provided enough supporting at the time of filing income tax returns,due to that my 80C Section was showing only Rs 76903 where actually i have supporting to show till Rs 1 lakh,so the tax was calculated based on the Supportings and Rs 32503  was deducted from my salary,The details is updated in the Form 16 document.Now i have to get back the returns since i have the proofs with me. So during filing IT Returns ...

If you are facing any issue with the snap shot mismatch  while deploying the Assets to Staging,Production,run the below query in the CA       You will  get the latest snap shot ID for Staging and Production. In CA Server,Go to the Component Browser,Browse to the path http://hostname:port/dyn/admin/nucleus/atg/epub/DeploymentServer Enter the snapshot id in the property Force snapshot ID click “init” button. Do the same for the Staging and Production environment.This will resolve the issue. See also Tweaking for Manage Snapshot Functionality See also BCC target site inaccessible  

Following are the implicit modules inside ATG EAR. atg_bootstrap.war: Nucleus is started by the module this also runs the servlet pipeline for DAF and DAS (for JHTML) modules . DAF servlet pipeline will be used for serving JSP Pages and J2EE Servlets. DAS Pipeline will be used for serving JHTML pages and Dynamo Servlets atg_bootstrap_ejb.jar: You know how the ATG classes are loaded by the application which you can see inside the atglib folder generally, There will be a EJB with a single session inside this module.The class loader of this session EJB will take care of  loading the classes for ATG application. atg_admin.war: ATG Component Browser or Dynamo Administration UI  will be started using this module

Basically two modes for EAR Creation, Development Mode and Standalone Mode,Main difference between these two is how the application access the Nucleus configuration information.For Development mode,the configuration information is accessed through the ATG installation and for other it takes from the EAR file. Ant File Application generally uses their own Ant build files to generate/create ATG EAR,it use  CreateUnpackedEarTask which uses clasees present inside assembler.jar.we can also use the runAssembler command directly. runAssembler for development mode runAssembler XXX.ear -m Modules .This will create the ear in the exploded form which is generally used in our day to day development environment runAssembler for standalone mode runAssembler [-standalone] XXX.ear -m Modules . This will create the ear in the  standalone form,which is used in production enviornment where you may not need an ATG installed platform to run the applicati...
