I found a bug in Oracle 11g today related to startup, I did startup

It said Oracle instance started
Shwhed me sga information
SHowd Database Mounted

After mounted it got hung, in the past after 10 minute sor so, it will show I thing database open, but today it did for hours.

I thought my database was not opened. then my users told that they are accessing database without problem,

So, I opened another problem and wow I could connect so database was open eventhough it wa shung in startup.

HAs anyone notice dthis with Oracle

This Oracle is really buggy. I did not notice while I was testing for last 3 months, but as soon as I went to production, I have encountered this problem.

Now my scripts for shuttiong down database etc will not work because they will hung. Received on Tue May 18 2010 - 16:15:55 CDT
