TNS 12549 error on installing Oracle 10g on Windows XP Home?

Question

Hi,
I installed Oracle 10g on Windows XP Home by clicking on Disk1\install\setup (NOT Disk1\setup as instructed since that did not work). Everything seemed to go fine except towards the end of the install I got a whole bunch of errors saying that "operating system resource quota exceeded". There were options to Ignore or Abort at most of these stages. I chose Ignore and the whole install seemed to complete but I am not able to connect to the database using sqlPlus. I looked at the log files created where I saw a whole bunch of errors in several files. For example in sqlnet log, I saw this error (among others) appeneded below. It seems obvious that some resource quotas were exceeded but I am not able to figure out exactly what quotas should be increased. Any help regarding this would be greatly appreciated.
Thanks.

XP Home is not supported, despite of this some people get oracle to work.
But in your case, possibly your machine has simply not enough resources, 12549 is a very generic error. Check the hardware requirements in the installation guide.
