Oracle 26ai Silent Mode 설치 테스트

pat98 — Wed, 17 Jun 2026 12:54:26 +0900

Silent Mode 로 설치 테스트 (Enterprise Edition 임)

이전에 19c 방식과 비슷하면서 약간 다르다.

Oracle 26ai SE2 설치 테스트

pat98 — Wed, 17 Jun 2026 12:48:00 +0900

26ai 는 아직 On-Premises에 Enterprise Edition 만 있음

클라우드는 지원이 된다.

일단 GUI에서는 안되니 silent mode 로는 되나? 테스트 한번해봄..

특정사이트에서 pdf 화일만 download 받는 방법

pat98 — Wed, 10 Jun 2026 10:37:51 +0900

특정사이트에서 필요한 파일만 받고 싶은 경우가 있다.

예를 들어 아래의 오라클 기술문서 Manual 사이트에서 전체 pdf 화일만 긁어서 다운 받고자 할 때 이렇게 하면 노가다 없이 쉽게 받아진다. (Chrome 확장프로그램 써도 되지만 커맨드로 간단하게)

문제가 발생했습니다. 나중에 다시 시도해 주세요 (14) 제미나이 프로

pat98 — Sun, 31 May 2026 12:47:20 +0900

최근 구글 제미나이 프로를 많이 쓰게 되면서 웹에서는 잘되는데 유독 핸드폰에서는 유독 이런 증상이 많이 발생하는 것을 경험했다.

문제가 발생했습니다. 나중에 다시 시도해 주세요 (14)

한번 더 누르면 되는데 여간 귀찮은게 아니다.

해결방법 :

여러가지 삽질하다가 찾아낸 방법은 뜬금없이 구글성인 인증을 하는 것이다.

https://myaccount.google.com/age-verification?utm_source=p0

1. 카메라로 얼굴인식 인증 (안경 쓴 경우는 벗고 촬영)

2. 카드번호 로 인증

둘 중에 편한 방법으로 하면된다.

인증을 마치고 다시 재실행하면, 언제그랬냐는 듯이 답변이 바로바로 나온다.

-> 오류가 완전히 없어지지는 않았지만 횟수가 현저히 줄었다.

CVE-2026-31431 취약점 업데이트 (Oracle Linux 인 경우)

pat98 — Wed, 20 May 2026 11:02:08 +0900

[취약점 개요 및 영향도]

1. 취약점 개요

A. CVE ID : CVE-2026-31431

B. 심각도 : Important (CVSS 7.8 / HIGH)

C. 영향 범위 : Linux Kernel 4.14 이상 (RHEL 8, 9, 10)

D. 취약점 : crypto: algif_aead (커널 암호화 인터페이스)

2. 취약점 영향도

A. 커널 암호화 인터페이스(algif_aead)의 연산 오류로 인해, 로컬 사용자가 페이지 캐시 조작을 통해 root 권한을 획득할 수 있는 취약점

B. 로컬 권한 상승(LPE) 취약점으로, 시스템에 일반 사용자 접근 권한이 있어야 악용이 가능

C. 공격 형태: 일반 유저 계정으로 Linux 암호화 API를 악용해 메모리 속 파일을 변조, root 권한을 획득하는 로컬 권한 상승(LPE) 공격

D. 공격 대상: 2017년 이후 출시된 Linux 커널(4.14~)을 사용하는 모든 서버, VM, 컨테이너 환경

다시 시도

1. opatch rollback -id 39034528 -silent -no_relink

이렇게 하면 relink 작업 수행하기 않기 때문에 rollback 까지는 잘 수행됨.

2. 그러나 이후 sqlplus 접속 시동하면

sqlplus: error while loading shared libraries: libclntshcore.so.19.1: cannot open shared object file: No such file or directory

3. 기존에 있던 19.30 RU 까지 다시 Rollback 진행해 봄

opatch rollback -id 38632161 -silent

4. 마찬가지로 no_relink 로 해야 진행이 됨.

opatch rollback -id 38632161 -silent -no_relink

5. 다시 원하는 19.30 RU (38632161) 적용함.

opatch apply /u01/install/38632161 -silent

결론 :

=> RHEL 9.x 환경에서는 RU rollback 작업이 원활하지 않을수 있으며, 전부 제거후 원하는 버전으로 다시 적용하는 것이 나은것으로 잠정 결론, (- applyRU 로 설치하기 때문? 인듯)

RHEL9 환경에서 CRS autostart 되지 않는 문제

pat98 — Fri, 24 Apr 2026 17:30:52 +0900

이슈 :

- RHEL 9.X 설치후 crs autostart 되지 않는 문제

root@rac1:/root# crsctl config crs
CRS-4622: Oracle High Availability Services autostart is enabled.

Autostart 설정되어 있어도 Reboot 하면 자동으로 올라오지 않는다.

원인 :

RHEL 9 부터 chkconfig rpm 이 기본설치 되지 않음

https://access.redhat.com/solutions/6837271

Bugzilla:2018112[1]

The chkconfig package is not installed by default in RHEL 9

The chkconfig package, which updates and queries runlevel information for system services, is not installed by default in RHEL 9.

To manage services, use the systemctl commands or install the chkconfig package manually.

For more information about systemd, see Introduction to systemd. For instructions on how to use the systemctl utility, see Managing system services with systemctl.

해결책 :

그냥 해당 버전에 맞는 chkconfig 받아서 설치해 주면 됨. (난 RHEL 9.7 이였음)

예시)

rpm -Uvh chkconfig-1.24-2.el9.x86_64.rpm

warning: chkconfig-1.24-2.el9.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID fd431d51: NOKEY

이때 /etc/init.d/ 디렉토리가 존재하여 설치가 안되는 경우가 있는데 안에 화일들을 백업후 디렉토리 지웠다가 설치후에 다시 복원시켜주면 된다.

설치 후 Reboot 하여 Autostart 되는지 확인 !!!
