ERROR at line 1:
ORA-00942: table or view does not exist

ls /oracle/oracle//product/10.2.0/db_1/dbs/orapworcl/$ORACLE_SID

ls $ORACLE_BASE/admin/$ORACLE_SID/bdump/alert_$ORACLE_SID.log

ls $ORACLE_BASE/admin/ora10g

二 总结

 

库名的查找

show parameter db_name;

select name from v$database;

 

实例名

select instance_name from v$instance;

show parameter instance_name;

 

Oracle服务器：库名+访问名

 

数据文件

select name from v$datafile;

 

控制文件

select name from v$controlfile;

 

日志文件

select member from v$logfile;

 

归档日志

desc v$archived_log;

select name from v$archived_log;

 

参数文件

select value from v$spparamerer where name=’spfile’;

select value from v$paramerer where name=’spfile’;

 

密码文件

ho ls $ORACLE_HOME/dbs/orapw$ORACLE_SID

 

告警日志

ho ls$ORACLE_BASE/admin/$ORACLE_SID/bdump/alert_$ORACLE_SID.log

ho ls $ORACLE_BASE/admin/ora10g
