Using Oracle Trace Analyzer (trcanlzr.sql)
Dave Moore: Author of Oracle Utilities
Oracle has provided another utility initially designed for performance tuning Oracle Applications. Trace Analyzer is provided in the form of a PL/SQL package (TRCA$ ). The Trace Analyzer utility is available via download on the Oracle Metalink web site.
How Oracle trace analyzer Works
Trace Analyzer requires that a one-time configuration be performed. During this configuration, many objects are installed in the database to serve as a tracing repository. Once downloaded from Metalink and installed, a SQL script can be executed passing in the name of the trace file.
Executing Oracle Trace Analyzer
First, tracing needs enabled at the appropriate level. For example, to provide maximum trace data, a Level 12 trace can be started for the current session:
SQL> ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT FOREVER, LEVEL 12';
After the session executes for enoug ......

Most of admins neglect setting password on TNSlsnr Clients for Oracle databases. Oracle ensures that you can either connect to TNSlsnr on a localhost or through mapping to a remote Oracle database using .ora files.
This is not the case anymore Based on Jwa perl client.
This client is a FULL client, with Packet crafting reassembled.
Supports all the commands as the version that is shipped with Oracle.
Allow you to totally control an unprotected Oracle Database Server remotelly , without having to map or install Oracle.
Download Here
Commands Supported
ping , version , service , status change_password, help, reload, save_config, set connect_timout set display_mode, set log_directory , set log_file , set log_status , show , spawn stop
this version works on Oracle9i.
On Oracle 10g only "version" command is working.
This is feedback i got from Pete Finnigan Oracle Security
The 10g listener is by default protected by local authentication rather than by a password like in the ......
数据库名(DB_NAME)、实例名(Instance_name)、以及操作系统环境变量(ORACLE_SID)
在ORACLE7、8数据库中只有数据库名(db_name)和数据库实例名(instance_name)。在ORACLE8i、9i中出现了新的参数，即数据库域名(db_domain)、服务名(service_name)、以及操作系统环境变量(ORACLE_SID)。这些都存在于同一个数据库中的标识，用于区分不同数据库的参数。
一、什么是数据库名(db_name)?
数据库名是用于区分数据的内部标识，是以二进制方式存储于数据库控制文件中的参数，在数据安装或创建之后将不得修改。数据库安装完成后，该参数被写入数据库参数文件pfile中，格式如下：
.........
db_name="orcl" #(不允许修改)
db_domain=dbcenter.toys.com
instance_name=orcl
service_names=orcl.dbcenter.toys.com
control_file=(...............
.........
在每一个运行的ORACLE8i数据库中都有一个数据库名(db_name),如果一个服务器程序中创建了两个数据库，则有两个数据库名。其控制参数据分属在不同的pfile中控制着相关的数据库。
二、什么是数据库实例名(instance_name)
数据库实例名则用于和操作系统之间的联系，用于对外部连接时使用。在操作系统中要取得与数据库之间 ......

最近从Excel中到了一些数据，结果一个列的数据是以逗号分隔的字符串，想把它拆分开找到了下边的方法，贴出来分享一下：
CREATE OR REPLACE PROCEDURE sptstr (srcstr varchar2) as
stmp varchar2(2000);
begin
select srcstr into stmp from dual;
while nvl(length(stmp),0) > 1
loop
insert into tabtest(col) select substr(stmp,1,instr(stmp,',')-1 ) from dual;
select substr(stmp,instr(stmp,',')+1) into stmp from dual;
end loop ;
commit;
end sptstr;
