Interesting Oracle Applications (EBS) Interview Questions

-
Below are some interesting interview questions that I have faced over the years.

  1. What is the difference between a concurrent manager and a cron job?


  2. Can one patch a CRS Oracle home with the CRS services up?


  3. Suppose, there are 2 nodes node1 and node2 with CRS cluster and one wants to patch node1. Can it be done with node2 being up?


  4. Suppose one fires a select statement and the data does not in the library cache, then the data, obviously, has to be fetched from the data files. Which background process is used for this purpose?


  5. What are the sizing requirements for say, a 100 concurrent users Oracle Apps Installation?


  6. What is the difference between a shared appl_top and a staged appl_top?

java.lang.ExceptionInInitializerError while trying to Access login page

-
Today morning, we (the DBAs) were faced with a strange issue. On Saturday (the 14th of February - (St.) Valentine's day!!), the UNIX boxes hosting our critical test instance went down for scheduled maintenance without any prior information. So, we could not bring down our databases and applications. As soon as the unix box came up, we encountered this issue. Let me briefly describe the environment, the issue, the analysis performed and of course, the solution to this most vexing problem. Environment : Apps Version : 11.5.10.2 with ATG RUP 5 DB Version : 10.2.0.3 Architecture : Two Node instance with database + admin on one tier and web server on another. PS : Another instance (development) exists on the same server with the same configuration, which was working fine. Issue : When trying to access the login page of Oracle Apps, received the below error. Even OAM login page was throwing the same error. Request URI: /OA_HTML/AppsLocalLogin.jsp Exception: java.lang.ExceptionInIniti

Solution to "End Program - WMS Idle"

Though this topic is unrelated any Apps DBA topics, I found it necessary to share the solution so that everyone benifits out of it ! Issue: I used to receive the below error message whenever I tried to shutdown windows XP. A rather vexing problem, no doubt. Cause: This message appears because when windows is trying to shutdown and end all the running processes, the WMS idle process keeps working. Thus an end-program message appears. The two most common reasons for this are: Scout service run by Nero 7 Microsoft Office Communicator 2005 Solution: The fix is simple, disable the Nero 7 scout service if it is enabled. For this, go to Start > All Programs > Nero > Tools > Nero Scout . On this screen , Uncheck Enable the Nero scout. This will fix the issue for most of the users, for the rest of you who are not using Nero are most probably getting this error because of Microsoft Office Communicator 2005. For that you need to either manually exit the communicator 2005 from the s

WGET shell Script for downloading patches

-
What I have to offer this time is a script using which you can download patches using WGET from Meta.....oops, from My Oracle Support, I should say! This script needs (or accepts) the following parameters: 1. Me...oops...MOS Username 2. MOS (I got it right this time!) password 3. Patch file name 4. ARU Number You can get 3 and 4 in the following way: Using MOS: Query for the particular patch, click on the download link, click on WGET Options on the left side bottom corner and then copy the WGET script to clipboard. That script will have both the patch name and the ARU number. Using HTML (supporthtml.oracle.com): Query for the particular patch, click on the patch, then RIGHT CLICK on the patch zip file link and click on copy shortcut in IE (or copy link location in Mozilla Firefox). This link will have both the patch file name and the ARU number. Using the classic patches window: Query for the particular patch, then RIGHT CLICK on the DOWNLOAD button and click on copy shortcut in IE (or
