all, do you have such experience about machine restart by itself without indication why ??? there is no indication on OS log - no log entries about why machine restart there is no indication on CRS log - no node eviction information simply machine restart by itself :) on each machine, I have 1 ASM instance and 2 database instance since 4 months ago, the machine was fine, without problem and never restart by itself of course :) please let me know if someone has the same experience...and please give me a clue ...... -- regards ujang Joyoboyo's prophecy on 1st industrial revolution: * Tanah Jowo kalungan wesi. The island of Java will be circled by an iron necklace. * Prahu mlaku ing dhuwur awang-awang. There will be a boat flying in the sky. * Pasar ilang kumandhange There will be markets without crowds * Akeh udan salah mongso. Rains will fall in the wrong season. -- //www.freelists.org/webpage/oracle-l
