23ai SYSTEM, SYSAUX, USERS Big tablespace 사용하지 않기
23ai SYSTEM, SYSAUX, USERS Big tablespace 사용하지 않기
23ai 는 Default Type 이 Big File 이라 초기생성시부터 Small file 로 생성가능한지 테스트 진행..
현재 상태는 아래와 같다.
SQL> select TABLESPACE_NAME, BIGFILE from DBA_TABLESPACES;
TABLESPACE_NAME BIG
------------------------------ ---
SYSTEM YES
SYSAUX YES
UNDOTBS1 NO
TEMP NO
USERS YES
SQL> alter session set container=PDB1;
Session altered.
SQL> select TABLESPACE_NAME, BIGFILE from DBA_TABLESPACES;
TABLESPACE_NAME BIG
------------------------------ ---
SYSTEM YES
SYSAUX YES
UNDOTBS1 NO
TEMP NO
USERS YES
CDB/PDB 모두 Big File 이다.
1. 우선 기본 Template 에서 아래 부분을 Big file 로 지정된 부분을 모두 false 로 변경

2. 스크립트를 실행해서 /u01/app/oracle/admin/TESTC/scripts/TESTC.sh
Database 를 생성
3. Database 생성시 많이 오래 걸림....1시간 30분 정도
4. 완료가 되면 확인을 해 보자.
