Creating defaultsfile - an easy guide!

-
This post is for the automation fanatics and enthusiasts. Of course, the others aren't excluded! The defaultsfile option that can be used with adutilities is a handy option to save time during patching or other maintenance activities.

Though the defaultsfile gets a mention by almost everyone in the context of reducing downtime, the method of creating it is not, unfortunately. In this post, I'd like to share this using an example - compiling apps schema using adadmin.
Note: The full explanation of creating a defaultsfile is mentioned in Chapter 2 (Maintaining Your System) of the Oracle Applications Maintenance Procedures.
1. Run adadmin command as below:

adadmin defaultsfile=$APPL_TOP/admin/$TWO_TASK/<DEFAULTS_FILE_NAME>


e.g.:

adadmin defaultsfile=$APPL_TOP/admin/$TWO_TASK/adadmin_cmpl_apps_schema.txt


The above command searches for a file with name adadmin_cmpl_apps_schema.txt in $APPL_TOP/admin/$TWO_TASK directory. If it exists, it uses the values provided in that file. Else, it creates a new file and the contents of the new file would be the answers that one provides at the subsequent prompts of adadmin.

Note: Not mentioning the correct path would error out as below. So, always ensure that you mention the full path to the default file.

$ adadmin defaultsfile=adadmin_maint_on.txt

Copyright (c) 2002 Oracle Corporation
Redwood Shores, California, USA
Oracle Applications AD Administration
Version 11.5.0

NOTE: You may not use this utility for custom development unless you have written permission from Oracle Corporation.

You have not specified the correct path for defaults file.

The expected location of the defaults file is
$APPL_TOP/admin/$TWO_TASK
and you must provide full access path to the file.

2. Assuming that the defaultsfile does not exist, proceed as you normally would for compiling apps schema.

3. Once the compilation is complete, exit out of adadmin and look for the file $APPL_TOP/admin/$TWO_TASK/adadmin_cmpl_apps_schema.txt.

4. Voilà! You are done! You have the defaultsfile (including passwords) for compiling apps schema. Whenever you want to compile apps schema using adadmin NON-INTERACTIVELY, run the below command:

$ adadmin defaultsfile=$APPL_TOP/admin/$TWO_TASK/adadmin_cmpl_apps_schema.txt

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
