Cause: After patch application, Maintenance mode is not disabled.

In my case, I encountered this error while accessing oracle E-business suite, I started the applications before disabling Maintenance mode which is incorrect.

Solution :

1) Login to applmgr user

2) Stop apache 

3) Run adadmin

4) use option 5 to disable maintenance mode

AD Administration Main Menu

————————————————–

1.Generate Applications Files menu

2.Maintain Applications Files menu

3.Compile/Reload Applications Database Entities menu

4.Maintain Applications Database Entities menu

5.Change Maintenance Mode

6.Exit AD Administration

Enter your choice [6] : 5

Please select an option:

1.Enable Maintenance Mode

2.Disable Maintenance Mode

3.Return to Main Menu

Enter your choice [3] : 2

sqlplus -s &un_apps/***** @/apps/vision/apps/apps_st/appl/ad/12.0.0/patch/115/sql/adsetmmd.sql DISABLE

Successfully disabled Maintenance Mode.

5) Restart Apache. 

We can even  enable or disable maintenance mode without using adadmin, 

ENABLE maintenance mode:

sqlplus -s apps/apps @$AD_TOP/patch/115/sql/adsetmmd.sql ENABLE

DISABLE maintenance mode:

sqlplus -s apps/apps @$AD_TOP/patch/115/sql/adsetmmd.sql DISABLE

Check the current status of Maintenance Mode:

select fnd_profile.value(‘APPS_MAINTENANCE_MODE’) from dual;

MAINT     =  MAINTENANCE MODE is ENABLED

NORMAL =  MAINTENANCE MODE is DISABLED
