How To Create A Custom Concurrent Program With Host Method and
Pass Parameters To The Shell Script [ID 266268.1]

Type HOWTO
Status PUBLISHED
Applies to: Oracle Application Object Library - Version: 11.5.0
to 11.5.10.2 - Release: 11.5 to 11.5 Goal PURPOSE: -------To
explain how to create a custom concurrent program with Host as the
method (shell script) and pass a number of user parameters from the
concurrent program to the shell script. This example will implement
a concurrent program that receives two parameters at the runtime of
the concurrent program: the database username and the user's new
password to be changed. The shell script will connect to the
database as system. It will verify if the user's password can be
changed. (Note: Allowed users will be stored in a flat file on the
CM-node.) Assumptions: ----------1. Oracle Applications Release 11i
is used. We are changing the database user password, not Oracle
Applications user's password. 2. We will not define a new
application, responsibility, etc. within 11i. We will use the
existing Application Object Library application and System
Administrator responsibility. 3. At runtime, the concurrent program
will need two parameters: database username and the new password.
If the database username is not listed in allowed_list.lst, the
user's password can not be changed. 4. The DBA group will be
notified by email once there is an attempt to change database
user's password. 5. FNDCPASS could be used, but this is not the
subject of this note. 6. If there is any user listed in the
allowed_list.lst (one user per line, no extra spaces) and that user
does not exist in the database, the concurrent request will
complete ok, but the DBA group will get a notification that
"database user doesn't exist". 7. Ensure the you test the procedure
in a test environment several times to become familiar with the
procedure. Verify that the program does what you require prior to
making the changes into production. 9. This procedure is not
supported by Oracle Support Services. This is just
an example and will have to be adjusted for your own needs.
SCOPE & APPLICATION: -------------------Technical Consultants,
Apps DBA, DBA. Solution Steps to create a custom concurrent program
with Host method and pass parameters to the shell
script.---------------------------------------------------------------------------------------------------
1. Copy/modify (if needed) chgdbpwd t o your CM-tier under
$FND_TOP/bin. 2. Create file allowed_list.lst under /s cripts.3.
Logon to Oracle Application 11i -> System Administrator

the following: - Seq: 10 , Parameter: Database User, Description:
Enter Database User to change the password for, Value Set: 15
Characters, and c lick on the Required: checkfield. - Seq: 11 ,
Parameter: Database User Passwor d, Description: Enter Database
User's New Password, Value Set: 15 Characters, an d click on the
Required: checkfield. Save your work.5. Navigate Security > Re

Reports and add one request Type: Program, Name: Change Database
User Password Save your w ork.6. Restart the Concurrent Managers.7.
Submit the concurrent request "Change Database User Password" ,
pass the parameters, under System Administrator res ponsibility. 8.
Connect using sqlplus to confirm the database user password has
changed.This procedure might help in case that HelpDesk will be
allowed to reset specific database password, without having access
to database users SYSTEM/SYS. Only the responsibility associated
with the concurrent request "Change Database User Password" defined
above is needed.-----script chgdbpwd starts here

start with parameter number 9. See the script chgdbpwd. Related
