Database Crashes With ORA-221, ORA-206, ORA-202, ORA-27072

One of my TEST database crashed with the above error.



Reason: it is due to BUG.



Solution: Apply the following patch 4401119



Solution



Workaround:

None. However the default server settings for AIX are:

MINIMUM number of servers [1]

MAXIMUM number of servers per cpu [100]

Maximum number of REQUESTS [4096]



This problem is improved slightly by changing the above values to something like:

MINIMUM number of servers (minservers) [64]

MAXIMUM number of servers per cpu(maxservers) [256]

Maximum number of REQUESTS (maxreqs) [8192]

Solution:

Apply patch 4401119 for the applicable Oracle version and Operating System



The issue is fixed in

10.1.0.5 (Server Patch Set)

10.2.0.2 (Server Patch Set)

11.1.0.6 (Base Release)
