1.startup Linux下Oracle报以下错
ORA-27102:out of memory Linux-X86_64

2.检查alter日志报:

  Current log# 1 seq# 514390 mem# 0: /opt/oracle/product/10.2.0/oradata/orcl/redo01.log

3.检查redo日志大小:
SQL>select bytes/1024/1024 from v$log;

BYTES/1024/1024
---------------
            50
            50
            50
4.参考其它省redo日志大小添加并修改redo日志大小后:

SQL> select bytes/1024/1024 from v$log;

BYTES/1024/1024
---------------
    500
    500
    500
    500
    500

5.检查alter日志中不再报Checkpoint not complete错误系统正常.
