有时候想查看一个package的信息，但是对于package的名字不是很确定，比如只知道一个大概，知道一些关键字，这个时候通过图形工具是查找不到package的信息的，而且对于package的信息，我只关心package里面有哪些存储过程，哪些函数等，看看简单的参数情况就可以了，类似sqlplus的desc的形式。
shell脚本的实现如下，
以下的脚本是查看是否有对应的package信息。
PROC_OWNER=`sqlplus -silent $DB_CONN_STR@$SH_DB_SID < set pagesize 50 feedback off verify off heading on echo off
col owner format a20
col object_name format a30
col subobject_name format a10
set linesize 150
break on object_name
select object_name,owner,subobject_name,object_type,object_id, created,last_ddl_time,status
from dba_objects where object_type like 'PACKAGE%' and object_name like upper('$2%') and owner=upper('$1')
order by object_name
/
exit;
END`
if [ -z "$PROC_OWNER" ]; then
echo "no object exists, please check again"
exit 0
else
echo '*******************************************'
echo " $PROC_OWNER    "

PACK_LIST=` sqlplus -s  $DB_CONN_STR@$SH_DB_SID < col name format a30
col text format a100
set linesize 200
set pages 50
break on name
select name,text  from dba_source where owner like UPPER('$1') and name like upper('$2%') and type='PACKAGE'
and (text like '%PROCEDURE %' or text like '%FUNCTION %' )
order by name,line;
exit;
END`
echo "  $PACK_LIST    "
echo '*******************************************'
fi 
exit

 运行脚本的情况如下所示。

[ora11g@rac1 dbm_lite]$ ksh findpack.sh sys dbms_metadata

如果想知道更多的package的信息，可以使用如下的脚本。

PROC_OWNER=`sqlplus -silent $DB_CONN_STR@$SH_DB_SID < set pagesize 40 feedback off verify off heading on echo off
col owner format a20
col object_name format a30
col subobject_name format a10
set linesize 150
break on object_name
select object_name,owner,subobject_name,object_type,object_id, created,last_ddl_time,status from dba_objects where object_type like 'PACKAGE%' and object_name=upper('$2') and owner=upper('$1')
ORDER BY OBJECT_ID
/
exit;
END`

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

sqlplus -silent $DB_CONN_STR@$SH_DB_SID < prompt .
set long 99999
set pages 0
select text
from dba_source
where type in ('PACKAGE BODY','PACKAGE') and name=upper('$2') and owner=upper('$1')
order by type, line;

EOF
exit

脚本运行情况如下：
[ora11g@rac1 dbm_lite]$ ksh showpack.sh sys DBMS_METADATA_UTIL|less
