We have a number of 18.104.22.168.0 oracle databases running on an NT server. We rebooted all our servers recently, and
one of the instances simply did not start up.
In NT Services, the OracleServicePODV and OracleStartPODV
both indicated they were running, but the database was NOT
up. We checked the strtPODV.cmd file - it had the correct
internal password and starttype. In Services, the startup was set to automatic, and the log on as System Account.
There is no record at all, not even of the shutdown ! The log details up to almost the minute of shutdown on 20th January, then the next entry is for 22nd january, when we started the database using svrmgr23.
