ORA-27302: failure occurred at: skgpspawn3 可能的原因及處理


問題現象:


Mon May 26 07:08:58 GMT+08:00 2014Process startup failed, error stack:
Mon May 26 07:08:58 GMT+08:00 2014Errors in file /oracle/app/admin/oracle10/bdump/oracle10_1_psp0_7733326.trc:
ORA-27300: OS system dependent operation:fork failed with status: 12
ORA-27301: OS failure message: Not enough space
ORA-27302: failure occurred at: skgpspawn3


根據報錯檢查本地磁碟,儲存空間,發現均無異常。


問題解決:

1、根本原因是因為交換空間 swap space (paging space) 設定不合理導致

正確配置參數:

RAM                                 SWAP
1GB to 2GB                     1.5 times RAM
> 2GB and <= 8GB          1 times RAM
> 8GB                              0.75 times RAM

In 11.2, it is:
RAM                                  SWAP
1GB to 2GB                     1.5 times RAM
> 2GB and <= 16GB        1 times RAM
> 16GB                            16GB RAM


2、此外還需注意下spfile 中是否含這類記憶體參數:

lock_sga=true
-  db_keep_cache_size=<High Value >


3、或者也有可能確實是系統實體記憶體不足了


4、當然 使用者的環境變數限制 的某些參數設定頁會導致這個問題 可以用這個命令查看下: ulimit -a
