hi everybody,
I increased the no.of servers to 7 as tamil said but constantly this error message is coming in alertlog-
skgpspawn failed:category = 27143, depinfo = 9261, op = spdcr, loc = skgpspawn
failed to start multi-threaded server 'S006', oer=27143
whats the problem???
its oracle 8.1.5 on NT 4.0 service pack 5.ora-600 I also saw in alertlog some days before,how to get rid of it?
any patches??

another thing -if at server i connect by giving scott/tiger I see ora-12560 tns protocol adapter error.

but if I issue scott/tiger@orcl its getting connected.this is happenning occasionally,if i restart for sometime the problem gets solved ,but again after sometime it comes.

thanks for all help.any suggestion is most welcome.
