Speech Carlaestevao80,
Good afternoon,
then ... would be able to check along with the network staff or the staff who take care of the UNIX and Linux part ... because apparently this seems to be a problem user permission ... from what I realized, I believe that UNIX or Linux ... is not letting you create the file c:\oracle\product\10.1.0\admin\orcl\bdump\orcl2_lck0_3916.trc: for lack of permission .. !!

Anything posts here in the forum !!

ABS of your friend Hahu
PS: May God bless everyone !!

Good morning Carla.

What is the version of your bank because it will probably be necessary to perform a patch to fix this problem.

From what I saw in error is a problem with the communication between the servers. It uses the IPC protocol and when it tries to use a communication channel the same is already closed. It would be nice to check if there is no link to link or communication bottleneck.

I found this link http://www.orafaq.com/forum/t/66063/0/
occurred when he stopped an instance ...

has no resemblance to your case?

I also work with 10g in rac, we could create a specific topic, it has some peculiarities.

Have you ever been able to find out something? We already know more what to do ...
