其实这个问题确切来说由于自己的疏忽所造成，之前做过RAC到单机的恢复实验，生产环境并无涉足，当时测试环境为Redhat5.4+Oracle1
一、概括
其实这个问题确切来说由于自己的疏忽所造成，之前做过RAC到单机的恢复实验，生产环境并无涉足，当时测试环境为RedHat5.4+Oracle11g+RAC，存储方式为ASM；生产环境为hpux+Oracle10g+RAC,存储方式为裸设备；就目前来看，，跟数据文件的存储方式有关。
二、 Hpux中，recover完成，执行’alter database open resetlogs’时报以下错误

根下目录dev为设置目录，我们需要修改redo日志目录，以完成数据库open操作，语句如下：
SQL> alter database rename file '/dev/vgdb/rredo1_1a_256m' to '/oracle/oradata/pmssd/redo01.log';
我并没有按照以上语句操作，而是重新创建了控制文件，这个问题是自己犯二了。修改完redo日志目录后就可以把数据库open了。
下面是我在linux ASM模式下的操作（’alter database open resetlogs’)。如以下日志，数据库自动重建了redo日志，并指定到了相应目录

MySQL은 sqlite와 어떻게 다릅니 까?Apr 24, 2025 am 12:12 AMMySQL과 Sqlite의 주요 차이점은 설계 개념 및 사용 시나리오입니다. 1. MySQL은 대규모 응용 프로그램 및 엔터프라이즈 수준의 솔루션에 적합하며 고성능 및 동시성을 지원합니다. 2. SQLITE는 모바일 애플리케이션 및 데스크탑 소프트웨어에 적합하며 가볍고 내부질이 쉽습니다.
MySQL의 색인이란 무엇이며 성능을 어떻게 향상 시키는가?Apr 24, 2025 am 12:09 AMMySQL의 인덱스는 데이터 검색 속도를 높이는 데 사용되는 데이터베이스 테이블에서 하나 이상의 열의 주문 구조입니다. 1) 인덱스는 스캔 한 데이터의 양을 줄임으로써 쿼리 속도를 향상시킵니다. 2) B-Tree Index는 균형 잡힌 트리 구조를 사용하여 범위 쿼리 및 정렬에 적합합니다. 3) CreateIndex 문을 사용하여 CreateIndexIdx_customer_idonorders (customer_id)와 같은 인덱스를 작성하십시오. 4) Composite Indexes는 CreateIndexIdx_customer_orderOders (Customer_id, Order_Date)와 같은 다중 열 쿼리를 최적화 할 수 있습니다. 5) 설명을 사용하여 쿼리 계획을 분석하고 피하십시오
MySQL에서 트랜잭션을 사용하여 데이터 일관성을 보장하는 방법을 설명하십시오.Apr 24, 2025 am 12:09 AMMySQL에서 트랜잭션을 사용하면 데이터 일관성이 보장됩니다. 1) STARTTRANSACTION을 통해 트랜잭션을 시작한 다음 SQL 작업을 실행하고 커밋 또는 롤백으로 제출하십시오. 2) SavePoint를 사용하여 부분 롤백을 허용하는 저장 지점을 설정하십시오. 3) 성능 최적화 제안에는 트랜잭션 시간 단축, 대규모 쿼리 방지 및 격리 수준을 합리적으로 사용하는 것이 포함됩니다.
MySQL을 통해 어떤 시나리오에서 PostgreSQL을 선택할 수 있습니까?Apr 24, 2025 am 12:07 AMMySQL 대신 PostgreSQL을 선택한 시나리오에는 다음이 포함됩니다. 1) 복잡한 쿼리 및 고급 SQL 기능, 2) 엄격한 데이터 무결성 및 산 준수, 3) 고급 공간 기능이 필요하며 4) 큰 데이터 세트를 처리 할 때 고성능이 필요합니다. PostgreSQL은 이러한 측면에서 잘 수행되며 복잡한 데이터 처리 및 높은 데이터 무결성이 필요한 프로젝트에 적합합니다.
MySQL 데이터베이스를 어떻게 보호 할 수 있습니까?Apr 24, 2025 am 12:04 AMMySQL 데이터베이스의 보안은 다음 조치를 통해 달성 할 수 있습니다. 1. 사용자 권한 관리 : CreateUser 및 Grant 명령을 통한 액세스 권한을 엄격히 제어합니다. 2. 암호화 된 전송 : 데이터 전송 보안을 보장하기 위해 SSL/TLS를 구성합니다. 3. 데이터베이스 백업 및 복구 : MySQLDump 또는 MySQLPump를 사용하여 정기적으로 백업 데이터를 사용하십시오. 4. 고급 보안 정책 : 방화벽을 사용하여 액세스를 제한하고 감사 로깅 작업을 가능하게합니다. 5. 성능 최적화 및 모범 사례 : 인덱싱 및 쿼리 최적화 및 정기 유지 보수를 통한 안전 및 성능을 모두 고려하십시오.
MySQL 성능을 모니터링하는 데 사용할 수있는 몇 가지 도구는 무엇입니까?Apr 23, 2025 am 12:21 AMMySQL 성능을 효과적으로 모니터링하는 방법은 무엇입니까? Mysqladmin, Showglobalstatus, Perconamonitoring and Management (PMM) 및 MySQL Enterprisemonitor와 같은 도구를 사용하십시오. 1. MySQLADMIN을 사용하여 연결 수를보십시오. 2. showglobalstatus를 사용하여 쿼리 번호를보십시오. 3.pmm은 자세한 성능 데이터 및 그래픽 인터페이스를 제공합니다. 4. MySQLENTERPRISOMITOR는 풍부한 모니터링 기능 및 경보 메커니즘을 제공합니다.
MySQL은 SQL Server와 어떻게 다릅니 까?Apr 23, 2025 am 12:20 AMMySQL과 SqlServer의 차이점은 1) MySQL은 오픈 소스이며 웹 및 임베디드 시스템에 적합합니다. 2) SQLServer는 Microsoft의 상용 제품이며 엔터프라이즈 수준 애플리케이션에 적합합니다. 스토리지 엔진의 두 가지, 성능 최적화 및 응용 시나리오에는 상당한 차이가 있습니다. 선택할 때는 프로젝트 규모와 향후 확장 성을 고려해야합니다.
MySQL을 통해 어떤 시나리오에서 SQL Server를 선택할 수 있습니까?Apr 23, 2025 am 12:20 AM고 가용성, 고급 보안 및 우수한 통합이 필요한 엔터프라이즈 수준의 응용 프로그램 시나리오에서는 MySQL 대신 SQLServer를 선택해야합니다. 1) SQLServer는 고 가용성 및 고급 보안과 같은 엔터프라이즈 수준의 기능을 제공합니다. 2) VisualStudio 및 Powerbi와 같은 Microsoft Ecosystems와 밀접하게 통합되어 있습니다. 3) SQLSERVER는 성능 최적화에서 우수한 성능을 발휘하며 메모리 최적화 된 테이블 및 열 스토리지 인덱스를 지원합니다.

mPDF는 UTF-8로 인코딩된 HTML에서 PDF 파일을 생성할 수 있는 PHP 라이브러리입니다. 원저자인 Ian Back은 자신의 웹 사이트에서 "즉시" PDF 파일을 출력하고 다양한 언어를 처리하기 위해 mPDF를 작성했습니다. HTML2FPDF와 같은 원본 스크립트보다 유니코드 글꼴을 사용할 때 속도가 느리고 더 큰 파일을 생성하지만 CSS 스타일 등을 지원하고 많은 개선 사항이 있습니다. RTL(아랍어, 히브리어), CJK(중국어, 일본어, 한국어)를 포함한 거의 모든 언어를 지원합니다. 중첩된 블록 수준 요소(예: P, DIV)를 지원합니다.
