The system has not been taken off maintenance mode completely

A problem was reported by the users stating they are seeing the following warning message:

"The system has not been taken off maintenance mode completely"

When I started working on this issue, I made the following observations:

- Users with profile option "Self Service Personal Home Page mode" set to "Framework Only" saw this warning message when they logged in.
- Users with profile option ""Self Service Personal Home Page mode" set to "Personal Home Page" did not see this warning message.
- Not all users who have the "Self Service Personal Home Page Mode" set to "Framework Only" experienced this issue. About a third of users were not seeing this message.
- A patch was applied in our environment previously.
- A quick check from "adadmin" revealed that maintenance mode had been disabled.

As I continued to work on this issue, I found that the reason for this problem was that the apps services on mid-tiers were started after patching without disabling the maintenance mode. The Maintenance Mode was later disabled and the services on third mid-tier brought up. This was the reason users were experiencing the warning message.

Corrective Action: Bounce of online midtier services which were started before disabling the maintenance mode.

Troubleshooting tips:

A comparison of apache/jserv startup time stamp on each online box with the maintenance mode disabled time stamp in adadmin log would reveal whether or not apache/jserv was started before disabling maintenance mode. The corrective action will need to be applied to only those online midtiers where services were started before maintenance mode was disabled.
