On our AIX lpar we have the following settings...
lsattr -El sys0| grep maxuproc
maxuproc 16384 Maximum number of PROCESSES allowed per user True
However for a number of hours the alert log posted these type of entries....
ORA-27300: OS system dependent operation:fork failed with status: 11
ORA-27301: OS failure message: Resource temporarily unavailable
ORA-27302: failure occurred at: skgpspawn3
this went on for a couple of hours then stopped....
Not sure where to proceed , as this is a one time occurence for this db.
Thanks in advace
