After upgrading to 9.1 version we see that the ArcotAdmin and ArcotUDS log files are not generated.
Release : 9.1
Component : AuthMinder(Arcot WebFort)
We have made logger changes in ArcotAdmin and ArcotUDS applications in 9.1 version and it was noticed that adminserver.ini and udsserver.ini files were not updated in Websphere Environment where these applications are deployed, It was still using the old adminserver.ini and udsserver.ini file.
After adminserver.ini and udsserver.ini files from 9.1 environment were used in Websphere, we saw the log files are created successfully.
