Ref NoteID: ID 840963.1

Have performed below actions to fix it.

SQL> select sum(bytes/1024/1024),sum(maxbytes/1024/1024) from dba_data_files where FILE_NAME like '%system09.dbf';
SUM(BYTES/1024/1024) SUM(MAXBYTES/1024/1024)
-------------------- -----------------------
                1501                       0

SQL>alter database datafile '/u01/db/apps_st/data/system09.dbf' resize 1000M;

Check for Corruption Now: NONE :)

Unable To View workflow Status Diagram

In a fresh R12 installed instance, When clicked on the Status diagram following message appears "You have encountered an unexpected error. Please contact the System Administrator for assistance."

When pressed on the click Here link the below error message displays:
oracle.apps.fnd.framework.OAException: java.lang.NullPointerException ( and it displays lot of lines with the exception message)

Solution:

Set the profile option Server Timezone at Site level (should be set to the value of database timezone) and Bounce the Apache Server

Function not available to this responsibility. Change Responsibilities or contact your System Administrator

In R12 after setting up New CUSTOM TOP, When you try to access Forms we are hitting "Function not available to this responsibility. Change Responsibilities or contact your System Administrator"

Even after defining the CUSTOM_TOP properly and defining the TOP in application env, this error would occur.

Solution:

1)In R12 go to $INST_TOP/ora/10.1.2/forms/server
2)Make sure your CUSTOM_TOP is defined in  default.env
Example:
Add the entrey as below  in the default.env
XXXYZ=/u01/oracle/EBSR12/apps/apps_st/appl/xxxyz/12.0.0

3)Bounce adopmnctl.sh stopall & Startall

4)Re-test the issue.
