获取trace文件的脚本
mkdir /oracle/qwedir
create table sys.tab_ospid (SID NUMBER,SERIAL# NUMBER,PADDR RAW(8),SPID VARCHAR2(12));
启动捕获trace文件脚本
#!/bin/bash
. /oracle/.profile
sqlplus -s "/ as sysdba" <
set pagesize 0
set feedback off
set heading off
set trimout on
set trimspool on
spool /oracle/qwedir/trackspid.log
select 'exec dbms_system.set_ev('||aa.sid||','||aa.serial#||',10046,4,'''');'
from v\$session aa
where aa.type='USER'
and aa.username in ('ZHJS_APP','ZHJSBY','ZHJS_USER','ZHJS_PARAM')
and aa.program not like 'sqlplus%'
and aa.program<>'plsqldev.exe'
and aa.status='ACTIVE'
and not exists (select 1 from sys.tab_ospid bb where bb.sid=aa.sid and bb.serial#=aa.serial#);
spool off
insert into sys.tab_ospid
select aa.sid,aa.serial#,aa.paddr,bb.spid
from v\$session aa,v\$process bb
where aa.type='USER'
and aa.username in ('ZHJS_APP','ZHJSBY','ZHJS_USER','ZHJS_PARAM')
and aa.program not like 'sqlplus%'
and aa.program<>'plsqldev.exe'
and aa.status='ACTIVE'
and aa.paddr=bb.addr
and not exists (select 1 from sys.tab_ospid cc where cc.sid=aa.sid and cc.serial#=aa.serial#);
commit;
exit;
QWEEOF
ORA_CMD=`cat /oracle/qwedir/trackspid.log`
echo "-------------------------------------- "
echo $ORA_CMD
echo "-------------------------------------- "
sqlplus -s "/ as sysdba" <
exit;
ASDEOF
rm /oracle/qwedir/trackspid.log
exit;
可以放在crontab 定时几秒中运行
终止trace文件脚本
#!/bin/bash
. /oracle/.profile
sqlplus -s "/ as sysdba" <
set pagesize 0
set feedback off
set heading off
set trimout on
set trimspool on
spool /oracle/qwedir/ktrack.log
select 'exec dbms_system.set_ev('||sid||','||serial#||',10046,0,'''');'
from sys.tab_ospid;
spool off
exit;
QWEEOF
KORA_CMD=`cat /oracle/qwedir/ktrack.log`
echo "-------------------------------------- "
echo $KORA_CMD
echo "-------------------------------------- "
sqlplus -s "/ as sysdba" <
exit;
ASDEOF
rm /oracle/qwedir/ktrack.log
exit;
获取trace文件，将trace文件scp到其他服务器
select 'scp -P12321 /oracle/product/9.2/db/rdbms/log/cntjs_ora_'||SPID||'.trc oracle@135.148.12.1:/backup' from sys.tab_ospid;
ps -ef|grep LOCAL=NO
sqlplus "/ as sysdba"

oradebug tracefile_name
oradebug event 10046 trace name context off;
alter system set events '10046 trace name context forever,level 12';
alter system set events '10046 trace name context off';
create table mapping_table tablespace TJ_BK as
select object_id id,owner,substr(object_name,1,30) name from dba_objects
where object_type not in ('CONSUMER GROUP','EVALUATION CONTEXT','FUNCTION','INDEXTYPE','JAVA CLASS','JAVA DATA','JAVA RESOURCE','LIBRARY','LOB','OPERATOR','PACKAGE','PACKAGE BODY','PROCEDURE','QUEUE','RESOURCE PLAN','SYNONYM','TRIGGER','TYPE','TYPE BODY')

目标端

sqlplus \' sys/oracle@cntjs as sysdba\'
create or replace directory SPADIR as '/backup';
---创建sqlset
