[20210401]跟踪sqlplus登录执行了什么.txt

--//昨天做了测试，链接http://blog.itpub.net/267265/viewspace-2765851/，顺便记录一下登录过程执行了什么。

1.环境:
SCOTT@book> @ ver1
PORT_STRING                    VERSION        BANNER
------------------------------ -------------- --------------------------------------------------------------------------------
x86_64/Linux 2.4.xx            11.2.0.4.0     Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

alter system set events 'sql_trace off';
alter system set events 'sql_trace [sql:cm5vu20fhtnq1|3nkd3g3ju5ph1|459f3z9u4fb3u|0ws7ahf1d78qa|5ur69atw3vfhj|0k8522rmdzg4k] bind=true, wait=true';
alter system set events '10046 trace name context forever, level 12';
--//使用sqlplus登录。
alter system set events 'sql_trace off';

2.测试结果如下：
$ extractsql.sh /u01/app/oracle/diag/rdbms/book/book/trace/book_ora_51309.trc
select privilege# from sysauth$ where (grantee#=:1 or grantee#=1) and privilege#>0
select /*+ connect_by_filtering */ privilege#,level from sysauth$ connect by grantee#=prior privilege# and privilege#>0 start with grantee#=:1 and privilege#>0

select decode(failover_method, NULL, 0 , 'BASIC', 1, 'PRECONNECT', 2 , 'PREPARSE', 4 , 0), decode(failover_type, NULL, 1 , 'NONE', 1 , 'SESSION', 2, 'SELECT',  4, 1), failover_retries, failover_delay, flags from service$ where name = :1
--//前面6条执行的sqlplus来之oracle执行文件内部，获取连接用户的权限。
SELECT USER FROM DUAL
BEGIN DBMS_OUTPUT.DISABLE; END;
SELECT ATTRIBUTE,SCOPE,NUMERIC_VALUE,CHAR_VALUE,DATE_VALUE FROM SYSTEM.PRODUCT_PRIVS WHERE (UPPER('SQL*Plus') LIKE UPPER(PRODUCT)) AND (USER LIKE USERID)
SELECT CHAR_VALUE FROM SYSTEM.PRODUCT_PRIVS WHERE   (UPPER('SQL*Plus') LIKE UPPER(PRODUCT)) AND   ((USER LIKE USERID) OR (USERID = 'PUBLIC')) AND   (UPPER(ATTRIBUTE) = 'ROLES')
BEGIN DBMS_APPLICATION_INFO.SET_MODULE(:1,NULL); END;
SELECT DECODE('A','A','1','2') FROM DUAL

3.继续测试toad的情况是否一样。

$ extractsql.sh book_ora_51333.trc

select SYS_CONTEXT('USERENV', 'SERVER_HOST'), SYS_CONTEXT('USERENV', 'DB_UNIQUE_NAME'), SYS_CONTEXT('USERENV', 'INSTANCE_NAME'), SYS_CONTEXT('USERENV', 'SERVICE_NAME'), INSTANCE_NUMBER, STARTUP_TIME, SYS_CONTEXT('USERENV', 'DB_DOMAIN') from v$instance where INSTANCE_NAME=SYS_CONTEXT('USERENV', 'INSTANCE_NAME')
select decode(failover_method, NULL, 0 , 'BASIC', 1, 'PRECONNECT', 2 , 'PREPARSE', 4 , 0), decode(failover_type, NULL, 1 , 'NONE', 1 , 'SESSION', 2, 'SELECT',  4, 1), failover_retries, failover_delay, flags from service$ where name = :1

4.收尾：
SYS@book> alter system set events '10046 trace name context off';
System altered.

SYS@book> alter system set events 'sql_trace off';
System altered.

5.附上extractsql.sh脚本：
$ cat ~/bin/extractsql.sh
#! /bin/bash
awk '/PARSING IN CURSOR/,/END OF STMT/' $1 | egrep -v '^PARSING|^END OF STMT'
