Hi Alejandro,
We could not fix it , and we raised a SAP ticket for this, but they were just killing time.
But at the end of the day this is a driver issue I think.We were going to move all the database data to a new oracle DB , so now I will try to connect with that DB and not the one for which I got this error.
I know thats not ideal thing to do , but did not have any other option.
Meanwhile what you can do is , read the above given solutions from Vadim and Praveen and do the following:
1) Check what is version of the database with which you want to connect PI.
2)Version of your PI system , and its JRE version
3)find a compatible driver (from an authentic source, I think this is where we made mistake , my basis person got it from some unreliable website)
4)Go to http://hostname:<j2eeport>/nwa/classloader -> in the dropdown menu
select Libraries -> filter for the component name
"com.sap.aii.adapter.lib" -> click the resources tab ->see list of installed drivers, does it show the driver?
5)Do a CPA cache refresh or server restart
6)If above all does not work try using XPI inspector and see the logs
