OS 환경 : Oracle Linux 4.8, 6.8 (64bit)
DB 환경 : Oracle Database 10.2.0.3, 11.2.0.4
방법 : 오라클 10g R2 에서 오라클 11g R2 수동 업그레이드 마이그레이션 방법
오라클 10.2.0.3 환경의 싱글 db에서 11.2.0.4 버전으로 수동 업그레이드 하는 방법을 설명함
asis 환경 : Oracle Linux 4.8, Oracle Database 10.2.0.3
참고 : Oracle Linux 4.8에 Oracle 10g R2 설치 가이드 ( https://positivemh.tistory.com/1138 )
tobe 환경 : Oracle Linux 6.8, Oracle Database 11.2.0.4(엔진만 설치)
작업방식 요약 :
todb 서버에 11gR2 엔진만 설치해둔 상태로 asis 서버에서 datafile, controlfile, redo log file을 tobe 서버로 가져와 수동 업그레이드 진행
총 2개의 서버를 사용함
그리고 oracle datafile 용 disk 를 하나 추가해서 /oradata1로 마운트 시켜놓은 상태임
참고 : Oracle Linux 4 새로넣은 디스크 mount 시키기 ( https://positivemh.tistory.com/741 )
이 작업 방식을 동일 서버에서 사용하는 경우 db 버전에 따라 os 업그레이드도 필요할 수 있음
os 버전이 높아서 db만 업그레이드 해도 된다면 동일서버에서 신규 엔진을 설치하여 업그레이드 가능함
작업 전 효율을 높이기 위해 리두로그 크기를 50mb에서 300mb로 증가시킴
참고 : 오라클 19c redo log 크기 자동 변경 스크립트 ( https://positivemh.tistory.com/1047 )

Miscellaneous Warnings
**********************************************************************
WARNING: --> Database is using a timezone file older than version 14.
.... After the release migration, it is recommended that DBMS_DST package
.... be used to upgrade the 10.2.0.3.0 database timezone version
.... to the latest version which comes with the new release.
WARNING: --> EM Database Control Repository exists in the database.
.... Direct downgrade of EM Database Control is not supported. Refer to the
.... Upgrade Guide for instructions to save the EM data prior to upgrade.
WARNING: --> Your recycle bin is turned on and currently contains no objects.
.... Because it is REQUIRED that the recycle bin be empty prior to upgrading
.... and your recycle bin is turned on, you may need to execute the command:
PURGE DBA_RECYCLEBIN
.... prior to executing your upgrade to confirm the recycle bin is empty.
.
**********************************************************************
Recommendations
**********************************************************************
Oracle recommends gathering dictionary statistics prior to
upgrading the database.
To gather dictionary statistics execute the following command
while connected as SYSDBA:
EXECUTE dbms_stats.gather_dictionary_stats;
**********************************************************************
Oracle recommends reviewing any defined events prior to upgrading.
To view existing non-default events execute the following commands
while connected AS SYSDBA:
Events:
SELECT (translate(value,chr(13)||chr(10),' ')) FROM sys.v$parameter2
WHERE UPPER(name) ='EVENT' AND isdefault='FALSE'
Trace Events:
SELECT (translate(value,chr(13)||chr(10),' ')) from sys.v$parameter2
WHERE UPPER(name) = '_TRACE_EVENTS' AND isdefault='FALSE'
Changes will need to be made in the init.ora or spfile.

DOC> The following PL/SQL block invokes UTL_RECOMP to recompile invalid
DOC> objects in the database. Recompilation time is proportional to the
DOC> number of invalid objects in the database, so this command may take
DOC> a long time to execute on a database with a large number of invalid
DOC> objects.
DOC>
DOC> Use the following queries to track recompilation progress:
DOC>
DOC> 1. Query returning the number of invalid objects remaining. This
DOC> number should decrease with time.
DOC> SELECT COUNT(*) FROM obj$ WHERE status IN (4, 5, 6);

DOC> SELECT COUNT(*) FROM UTL_RECOMP_COMPILED;
DOC>
DOC> This script automatically chooses serial or parallel recompilation
DOC> based on the number of CPUs available (parameter cpu_count) multiplied
DOC> by the number of threads per CPU (parameter parallel_threads_per_cpu).
DOC> On RAC, this number is added across all RAC nodes.
DOC>
DOC> UTL_RECOMP uses DBMS_SCHEDULER to create jobs for parallel
DOC> recompilation. Jobs are created without instance affinity so that they
DOC> can migrate across RAC nodes. Use the following queries to verify
DOC> whether UTL_RECOMP jobs are being created and run correctly:
DOC>
DOC> 1. Query showing jobs created by UTL_RECOMP
DOC> SELECT job_name FROM dba_scheduler_jobs

실행 전 참고
- RAC 의 경우 단일 인스턴스만 기동해야함
- TSTZ 데이터에 액세스하거나 저장하는 모든 애플리케이션이 중지되어 있어야함
- upg_tzv_apply.sql은 아무런 확인 없이 DB를 2번 다시 시작함
- 일반적으로 upg_tzv_apply.sql은 upg_tzv_check.sql 보다 시간이 덜 걸림
- Multitenant db의 CDB에 대해 실행하면 모든 PDB가 Close 됨
