概述

今天主要分享一下两个shell脚本，主要是为了查看数据库进程的相关信息和存储过程信息，下面一起来看看吧~

数据库连接脚本

use script settdb.sh for DB login details registry

#!/bin/bash
tmp_username=$SH_USERNAME
tmp_password=$SH_PASSWORD
tmp_db_sid=$SH_DB_SID

#check $1 and $2 should be mandatory from input
if [[ -z $1 ]] || [[ -z $2 ]]; then
echo '***********************************************'
echo 'WARNING :UserName And PassWord Is Needed!'
echo '***********************************************'

exit
fi
if [[ -z $3 ]] && [[ -z $ORACLE_SID ]];then
echo '***********************************************'
echo 'WARNING :There is Instance can be used !'
echo '***********************************************'
exit
fi

SH_USERNAME=`echo "$1"|tr '[a-z]' '[A-Z]'`
SH_PASSWORD=$2
echo '***********************************************'

if [[ -z $3 ]]
then
 SH_DB_SID=$ORACLE_SID
 echo 'Using Default Instance :'$ORACLE_SID
 echo .
else
 SH_DB_SID=`echo "$3"|tr '[a-z]' '[A-Z]'`
fi

if [[ $SH_DB_SID = $tmp_db_sid ]] && [[ $SH_USERNAME = $tmp_username ]] && [[ $SH_PASSWORD = $tmp_password ]];then
 echo 'Instance '$SH_DB_SID 'has been connected'
 echo '***********************************************'
 exit
fi

export SH_USERNAME=$SH_USERNAME
export SH_DB_SID=$SH_DB_SID
export SH_PASSWORD=$SH_PASSWORD
export DB_CONN_STR=$SH_USERNAME/$SH_PASSWORD
#echo $DB_CONN_STR
listfile=`pwd`/listdb
Num=`echo show user | $ORACLE_HOME/bin/sqlplus -s $DB_CONN_STR@$SH_DB_SID| grep -i 'USER ' | wc -l`
if [ $Num -gt 0 ]
 then
 ## ok - instance is up
 echo 'Instance '$SH_DB_SID 'has been connected'
 echo -e '--' `date`'-- n--'$SH_USERNAME@$SH_DB_SID 'has been connected --n' >> listdb
 echo '***********************************************'
 echo 'Initalize DB login details registry OK!'
 echo 'Now you can Execution script~'
 echo '***********************************************'
 $SHELL
 
 else
 ## inst is inaccessible 
 echo Instance: $SH_DB_SID Is Invalid Or UserName/PassWord Is Wrong 
 echo '***********************************************'
 exit
 fi
del_length=3
tmp_txt=$(sed -n '$=' listdb) 
echo '***********************************************'
echo '********* ' $SH_USERNAME'@'$SH_DB_SID '**********'
echo '***********************************************'
curr_len=`cat $listfile|wc -l`
if [ $curr_len -gt $del_length ]; then
echo ' There Are Below Sessions Still Alive '
echo '***********************************************'
fi
sed $((${tmp_txt}-${del_length}+1)),${tmp_txt}d $listfile | tee tmp_listfile
mv tmp_listfile $listfile

输出：

./settdb.sh 用户名 用户密码

showpid.sh

脚本内容：

#!/bin/bash
echo "=================================================查看数据库进程spid：$1的相关信息====================================================="
if [ -z "$1" ]; then 
 echo "no process has provided!" 
 exit 0

fi

输出：./showpid.sh 数据库进程ID

这个一般要跟前面的会话脚本配合使用，主要是为了获得数据库进程更多明细。

showproc.sh

脚本内容：

一开始是想输出存储过程明细的，但是考虑到shell脚本看这些内容毕竟很痛苦，所以改成了去获得当前数据库所有存储过程，特定的存储过程还是用plsql看吧~

#!/bin/bash
echo "=======================================查看数据库用户$1的存储过程信息=========================================="

set linesize 1000
select owner, object_name,object_id,object_type,aggregate,pipelined,parallel,interface,deterministic,authid from dba_procedures
where owner=upper('$1') and object_type='PROCEDURE'
/
exit;
END`

if [ -z "$PROC_OWNER" ]; then
 echo "no object exists, please check again"
 exit 0
else
 echo '*******************************************'
 echo " $PROC_OWNER "
 echo '*******************************************'

#sqlplus -silent $DB_CONN_STR@$SH_DB_SID <<EOF
#prompt .
#set long 99999
#set pages 0
#select text

#where type='PROCEDURE' and owner=upper('$1')

exit

输出：./showproc.sh rfuser
