1. alert_sid.log中查看'ORA-'的错误
清空日志:cat /dev/null > alert_wilson.log
此时,再查看alert_wilson.log文件,会发现已经增加了检查点信息了
locate alert_wilson.log
2. 检查“checkpoint”信息
SQL> show parameter log_ch
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_checkpoint_interval integer 0
log_checkpoint_timeout integer 1800
log_checkpoints_to_alert boolean FALSE
SQL> alter system set log_checkpoints_to_alert = true scope=both;
SQL> alter system checkpoint;
3. 检查有哪些用户连入oracle系统
select sid, serial#, username from v$session;
