EM 접속하는 법

1. port 주소 알기

cd $ORACLE_HOME/install

cat portlist.ini

 

2. EM 기동여부 확인

emctl status dbconsole

 

3. 접속

http://[[자기 ip 주소]]:1158/em

 

username : sys

shell 예

변수 $1로 만들어서 실행시

./파일명 넣을값

 vi a.sh

mkdir $1

 

ex) ./a.sh dddd

dddd 디렉토리가 만들어짐

이 것이 modifed parameter 파일 임

 

  예)db_recovery_file_dest_size (fra 크기)

	static	dynamic
script	1. 확인      show parameter o7 2. 수정     scope = both ->>     scope = spfile ->> 현재 셋팅은 바꾸지 않고, 파라미터 파일만 바꿈.     alter system set O7_DICTIONARY_ACCESSIBILITY = TRUE scope=spfile; 3. instance 재부팅    shutdown immediate; 4. 확인    show parameter o7	1. 현재값 확인      show parameter db_rec 2. 값 변경      ALTER SYSTEM SET db_recovery_file_dest_size = 3G SCOPE=BOTH 3. 확인      show prarmeter db_rec
em	spfile 탭에서만 수정후 재부팅 yse	current, spfile 탭 두 군데 다 고쳐줘야 함

 

 

통상적인 parameter 파일 백업

create pfile='/home/oracle/_setting/initorcl.ora.090519_1' from spfile;

고장내기--

[oracle@orcl ~]$ rm /u01/app/oracle/product/10.2.0/db_1/dbs/spfileorcl.ora

S SYS> shutdown abort
ORACLE instance shut down.
S SYS> startup
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/u01/app/oracle/product/10.2.0/db_1/dbs/initorcl.ora'

 

백업한 parameter 파일로 복구하기

   -pfile로 시작만 하기

   startup pfile='/home/oracle/_setting/initorcl.ora.090519_1' nomount;

 

  create spfile from pfile='/home/oracle/_setting/initorcl.ora.090519_1';

 

  shutdown

 

  startup

 

 

alert log 스크립트로 보기

1. alert log 위치 찾기

S SYS> @p
Enter value for key: background

NAME                 VALUE
-------------------- -----------------------------------------------------------             -
background_core_dump partial
background_dump_dest /u01/app/oracle/admin/orcl/bdump

2. alertlog 파일 열기

[oracle@orcl ~]$ cd  /u01/app/oracle/admin/orcl/bdump
[oracle@orcl bdump]$ vi alert_orcl.log

 

3. alter log 검색

/ 로 검색

정규 표현식 특수 문자는 앞에 \(역슬러쉬) 필요

ex)May 19 14:\(4\|5\)

 

 Dynamic Performance Views

momory에서 읽음

v_$ 로 시작

v$fixed_table에 리스트

계속 바뀜 

 

sys로 찾아야 함

 

 

 

 숙제

1.  자신만의 parameter file 내용 정리 체계 확립할 것.

2. alter log 파일 분석할 것,

   1. 내용의 종류 : 시각 기준으로 끊을 것.
   2. 시간 축 : 내용의 종류를 입력.
