This evening i googled a little bit, looked into some blogs and suddenly i thought about webservices and security... What about using SOAP with SSL?
The the first step should be to configure the Oracle HTTP Server with SSL.
This sounds very easy, so i took a look at the documentation. Brrr...
There was nothing useful. Only something like: "on the menu bar choose wallet manager"
BUT how can i choose this on the Linux or UNIX server?
After a long search i found this nice documentation.
I do not know, wether it is the right version and so on, but just the information that the cli is owm was enough...
Perhaps i will try it tomorrow evening or not, but now i know how to start and this is quite enough.
