I want to start our db on a sun solaris ultar80 with solaris2.7. I connect me as internal at sqlplus. Then i make a startup and after that the error occurs: ORA-27102 out of memory SVR4 Error:22:Invalid argument Then i look after the error ORA-27102 and i should consult the trace file for details: i looked after all the trace-files but there are no. So i controlled our init.ora if the all path are right. All is right. Whats now. Thanks for help Thomas Schmidt Best Regards Thomas Schmidt Thomas_Schmidt@eplus-online.de If you have no aims, you will never reach a goal !!!
