Question:
I received the following ORA-27300 error in my alert log:
ORA-27300: OS system dependent operation:spcdr:9261:4200 failed with status: 997
ORA-27301: OS
failure message: Overlapped I/O operation is in progress
ORA-27302: failure occurred at: skgpspawn
Process startup failed, error stack:
Errors in file /u01/home/oracle/diag/rdbms/xxxx.trc:
ORA-27300:
OS system dependent operation: fork failed with status: 11
ORA-27301: OS failure message: Resource temporarily unavailable
ORA-27302: failure occurred at: skgpspawn5
How do I deal with this ORA-27300 error?
Answer:
To diagnose any error, you first start by using the
oerr utility to display the ORA-27300 error:
ORA-27300: OS system dependent operation: string failed with status:
string
Cause:
OS system call error
Action:
Contact Oracle Support
I noted that the maximum user process for this server was set to
2047 and when I check the total number of process it is reaching the
OS limit, causing the ORA-27300 error. We need to check the
"processes" Oracle parameter to ensure that it is large enough and
we also need to increase the process limit to fix the ORA-27300
error and here are the commands for each OS:
Linux:
Increase the nproc in /etc/security/limits.conf file
Solaris
10: Increase the project.max-lwps value
For HP and
Solaris: Increase the maxuprc
For AIX:
Increase maxuproc
