检查表空间的使用
以下的脚本检测表空间的使用。如果表空间只剩下10%，它将会发送一个警告email。
##################################################################### ## ck_tbsp.sh ## ##################################################################### #!/bin/ksh sqlplus -s < tablespace.tmp mailx -s "TABLESPACE ALERT for ${2}" $DBALIST < tablespace.tmp fi
警告email输出的例子如下：
TABLESPACE_NAME USED (MB) FREE (MB) TOTAL (MB) PER_FREE ------------------- --------- ----------- ------------------- ------------------ SYSTEM 2,047 203 2,250 9 % STBS01 302 25 327 8 % STBS02 241 11 252 4 % STBS03 233 19 252 8 %
查找出无效的数据库对象
以下查找出无效的数据库对象：
#####################################################################
## invalid_object_alert.sh ##
#####################################################################
#!/bin/ksh . /etc/oracle.profile sqlplus -s <
STATUS FROM DBA_OBJECTS WHERE STATUS =
INVALID ORDER BY OWNER, OBJECT_TYPE, OBJECT_NAME; spool off exit ! if [ `cat invalid_object.alert|wc -l` -gt 0 ] then mailx -s "INVALID OBJECTS for ${2}" $DBALIST < invalid_object.alert fi$ cat invalid_object.alert OWNER OBJECT_NAME OBJECT_TYPE STATUS --------------------------------------------

监视用户和事务（死锁等）
以下的脚本在死锁发生的时候发送一个警告e-mail：
################################################################### ## deadlock_alert.sh ## ##################################################################
##!/bin/ksh .. /etc/oracle.profile sqlplus -s < 0 OR BLOCK > 0 ORDER BY block DESC; spool off exit ! if [ `cat deadlock.alert|wc -l` -gt 0 ] then mailx -s "DEADLOCK ALERT for ${2}" $DBALIST < deadlock.alert fi
