Alert users to possible database crashes with error 221 unable to write to controlfile on AIX 5L. The error stack that is generated is:
ORA-00221: error on write to controlfile
ORA-00206: error in writing (block 3, # blocks 1) of controlfile
ORA-00202: controlfile: '/u03/oradata/paimg/control03.ctl'
ORA-27072: File I/O error
IBM AIX RISC System/6000 Error: 22: Invalid argument
Additional information: 7
This problem is specific to Oracle 10g on AIX 5L.
Database crashes with ORA-221, ORA-206, ORA-202, ORA-27072
Impact:
The database impact is severe since it causes the database to crash. In addition this error is usually the result of a resource
exhaustion. So once it is encountered it is more than likely that this problem will be encountered again on the production
system.
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 for bug 4401119
