Symentec BE backup software is installed on Oracle host which is in Windows platform and the backup operating is normal. Then installing HostAgent AppProxy software, after starting AppProxy service, we find that the BE backup Oracle DB operation has problem.
Modify the port number to another one in HostAgent AppProxy configuration file. (Do not collide with other software.)
By default HostAgent AppProxy software uses OS 10000 port, same as BE software, which causes the collision.
After installing HostAgent AppProxy software, execute netstat -an to check current OS ports condition, which avoids collision. If the other software occupies No.10000 port, we should modify it before installing HostAgent AppProxy.
