Fatal Error occurred - check the log /appworxdv/usr/install/aw_install.log
This error occurs during installation against existing data if there are any changes made to the master name, ip, os user, oracle id, or net_connect.
As you can see from the above example excerpt from the aw_install.log, the installation detected that there was a change to the master ip address. When a difference is detected, you will generally be prompted to "Change Database to new values" to which you should enter in Y for yes. However, in 9.4.2 this causes the installation to fail. . If there are no changes to the Master, IP, User, Oracle_ID, or net_connect values, then you shouldn't run into this issue.
This issue has been resolved in Applications Manager 9.4.2 Hot Fix 1. Please download the 9.4.2 HF1 from Automic Download Center - Component Downloads and run the installation to resolve the issue.
