Restore Oracle Application Server ias_admin password ?

Just go to the directory $ORACLE_HOME/sysman/j2ee/conf. In this directory you'll find the configuration file jazn-data.xml. Inside this configuration file you'll find the definition of the ias_admin user including his encrypted password:
Here's my own ORACLE_Home Path : c:\oracle\FRHome_1\sysman\j2ee\config\jazn-data.xml
  • snippet from jazn-data.xml
Inside the tag <credentials> you see the encrypted password of the ias_admin. To reset the password, just change the value inside the tag <credentials> as follows:

  • snippet from jazn-data.xml

The new password you have to provide in clear text has to start with a "!". Be aware that the new password must match the password rules: minimum 6 signs and one sign must be a number. After your changes, stop the ASC and restart it with following commands:

  • emctl stop iasconsole
  • emctl start iasconsole
Now you can login with your new password and inside the jazn-data.xml the provided password in clear text is automatically changed into an encrypted password.

INSTR Function :

It calculates the position of specific text we define inside Character.

For example :

SELECT   INSTR ('cocacola', 'co', 2) FROM DUAL

The result is :


We can use combination of INSTR and SUBSTR to extract characters between specific text as following:

SELECT SUBSTR('1/9/1438', 1 ,INSTR('1/9/1438', '/', 1, 1)-1) "DAY", SUBSTR('1/9/1438', INSTR('1/9/1438','/', 1, 1)+1,

INSTR('1/9/1438','/',1,2)-INSTR('1/9/1438','/',1,1)-1) "MONTH", SUBSTR('1/9/1438', INSTR('1/9/1438','/', 1, 2)+1) "YEAR"

FROM dual;

The result is :
1  9  1438
