Retrieve Forgotten Apps Password in Oracle EBS R12

February 20th, 2023, posted in Oracle Queries
Share
I am going to share steps to retrieve the password in Oracle Apps.
But no guarantee that it will work on all EBS version. It was tested on R12.2.3.
 

Steps:

 
1: log in to the database server with sys user
 sqlplus / as sysdba
 
2: Create Function to decrypt the encrypted password
SQL> create FUNCTION apps.decrypt_pin_func(in_chr_key IN VARCHAR2,in_chr_encrypted_pin IN VARCHAR2)
 RETURN VARCHAR2  AS  LANGUAGE JAVA NAME ‘oracle.apps.fnd.security.WebSessionManagerProc.decrypt(java.lang.String,java.lang.String)
return java.lang.String’;  /
 
3 : Query for Encrypted password
SQL> select ENCRYPTED_FOUNDATION_PASSWORD from apps.fnd_user where USER_NAME=’GUEST’;

Output

 ENCRYPTED_FOUNDATION_PASSWORD
  ——————————————————————————–  ZG37E123746712BDB2D99E048FE44AE662F2713E2EDB443391BABA0414CADDB7A2E6DD45BBAFA7270A663E5EEBA837F5548A
 
4: Past the Encrypted password from the above query output into the below query and execute
SELECT apps.decrypt_pin_func
(‘GUEST/ORACLE’,’ZG37E123746712BDB2D99E048FE44AE662F2713E2EDB443391BABA0414CADDB7A2E6DD45BBAFA7270A663E5EEBA837F5548A’)
from dual;

Output

 APPS.DECRYPT_PIN_FUNC
(‘GUEST/ORACLE’,’ZG37E123746712BDB2D99E048FE44AE662F2713E2EDB443391BABA0414CADDB7A2E6DD45BBAFA7270A663E5EEBA837F5548A’)
  ——————————————————————————–
  oracle123
 
5: Test apps password is working or not
 SQL> conn apps/oralce123;
Connected.

Change Allowed In Items Primary UOM in Oracle EBS R12.2.9 And Higher Versions

December 1st, 2020, posted in Oracle EBS Application
Share

Allowed to change Item’s Primary UOM in Oracle EBS R12.2.9 and higher versions

 

Prior to Oracle EBS R12.2.9, Item’s Primary Unit Of Measure(UOM) can be selected only at the time of item creation and cannot be updated once the item is saved.

There is a new feature added in Oracle EBS 12.2.9 latest version, where it is allowed change item’s primary UOM after the item is created When no transactions exist like material transactions, Sales Orders, Purchase Orders, Work Orders, Onhand etc.,

Item’s UOM won’t be updated if there are transactions or related records exists. This is to Maintain data Integrity and avoid corruption.

  1. Creating “VM TEST” master item with primary uom as Each.

oracle application,oracle ebs,oracle master item,oracle inventory master items,oracle apps dba

2. Extending “VM TEST” item to M1 inventory org.

oracle application,oracle ebs,oracle master item,oracle inventory master items,oracle apps dba

3. Query “VM TEST” item in M1 inventory org.

oracle application,oracle ebs,oracle master item,oracle inventory master items,oracle apps dba

Initially the item is created with primary UOM as “Each”. This item is newly created and there are no transactions exist.

4. Change primary uom from EACH to EA in the master item form ( primary UOM is master controlled item attribute) -> A concurrent request will be submitted when UOM is changed and saved.

oracle application,oracle ebs,oracle master item,oracle inventory master items,oracle apps dba

5. It runs “EGO Spreadsheet Java Concurrent Program” process and completes normal when the UOM is changed.

oracle application,oracle ebs,oracle master item,oracle inventory master items,oracle apps dba,EGO Spreadsheet Java Concurrent Program

Note: The concurrent program will have error like below if there are any transactions exists.

MESSAGE NAME: INV_UOM_CANNOT_UPDATE
ERROR MESSAGE : You cannot update UOM field when the inventory transactions exist in current or one of child orgs.

6. Re-Query “VM TEST” in the organization items form for M1 inventory org. You can see that primary UOM is changed to EA

Decoded INST_TOP Oracle R12 INSTANCE_HOME

June 13th, 2020, posted in Oracle
Share

 

Features on this R12 INST_TOP

-All the logs files have been moved from APPL_TOP,ORACLE_HOME to this to top

  • All configuration files have been moved to INST_TOP
    like
    DBc file
    All the http related config files
    appsweb.cfg
    All the start or stop scripts
    all the OC4J related config files

-we can now share the Apps and technology stack among multiple nodes and even instances (Dev,Test, Production) as all the log and config are located in this top.We will have INST_TOP for each context.

-Configuration and log files are co-located

-Easier collection of instance state
-Minimize disk usage and maximize performance

Filesystem look

/inst/apps/ ($INST_TOP)
• /admin
• /scripts ($ADMIN_SCRIPTS_HOME) All the start and stop are here
• /appl ($APPL_CONFIG_HOME) All the apps env are here
• /fnd/12.0.0/secure ($FND_SECURE) dbc file lis located here
• /certs
• /logs ($LOG_HOME) all the logs are located
• /ora ($ORA_CONFIG_HOME)
/10.1.2
/10.1.3 ($ORACLE_CONFIG_HOME) all the techstack(oacore,forms) related config files
• /pids
• /portal
• /rgf

Some more changes to variable

OA_HTML =$COMMON_TOP/webapps/oacore/html
JAVA_TOP=$COMMON_TOP/java/classes
AF_JLIB=$COMMON_TOP/java/lib
JAVA_BASE=$COMMON_TOP/java/

Advantage  of INST_TOP

-Clear distinction between the shared file system and the file system unique to an instance
-Ability to share code (Apps, technology stack) among multiple  nodes and even instances (Development ,Test, Production)
-Enables split ownership of applications and technology stack file systems
-Improves code safety by making shared file system read-only while not patching
-Configuration and log files are co-located
-Easier collection of instance state
-Ability to use network or local storage for various file system portions
-Minimize disk usage and maximize performance

R12.2 Changes

-R12.2 contains the Fusion Middleware 11g tech-stack. The logfile and configuration files is located in that Oracle Home

–Concurrent Manager log/out files have been moved in Non editioned File system

Where to Put INST_TOP in shared file system

It is recommended to put INST_TOP on local filesystem  in shared APPL_TOP filesystem  architecture. This is because of the Apache mutex problem.Apache performance is highly sensitive to mutex file access latency, and at higher loads is also sensitive to I/Os per second. In case you have INST_TOP on shared filesystem, it is suggested to point these context variable to local file-system

s_lock_pid_dir
s_pids_dir
s_web_pid_file

 

 

Conclusion
