am using oracle 92 and i'm trying to link my java programs to it. however since i got a cable internet connection my java programs keep throwing oracle errors. ORA-12547: TNS:lost contact or /and ORA-12570: TNSacket reader failure. However if i physically disconnect the internet (pull it out of the usb) they work fine. Im thinking i have a problem with sql net. (i tried using toad but also came up with similar tns problems). Also looked in the process manager and (an assumption) i don't see a process for sql net. there is one for sql plus though. Any ideas how to fix this problem. If i have to reinstall oracel is there a way i can just install the necessary components instead of the whole bloody thing.

cheers
