Oracle从10g升级到11g详细步骤数据库旧版本:10.2.0.4
数据库新版本:11.2.0.2
OS 版本: Solaris 10
参考文档:Complete Checklist for Manual Upgrades to 11gR2 [ID 837570.1]
第一部分 - 安装11gR2软件
这里对软件的安装就不详细说明了,可以参考相应的文档。
这里需要注意的是:如果你想在11gr2上打上最新的PSU或CPU,可以先在软件级别上打上PSU或CPU,这样就不用跑两次catbundle.sql,减少停机时间。
第二部分 - 初步检查
1. 在升级之前,确保所有的组件和对象都是valid:
select substr(comp_name,1,40) comp_name, status, substr(version,1,10) version from dba_registry order by comp_name; --针对组件
select substr(object_name,1,40) object_name,substr(owner,1,15) owner,object_type from dba_objects where status='INVALID' order by owner,object_type; --针对对象
如果有invalid的对象,运行utlrp.sql重新编译对象。
2. 确保sys和system下没有重复的对象:
select object_name, object_type from dba_objects where object_name||object_type in (select object_name||object_type from dba_objects where wner = 'SYS') and wner = 'SYSTEM';
上面这条语句只能返回以下4条记录:
OBJECT_NAME OBJECT_TYPE
---------------------------------------- ---------------
DBMS_REPCAT_AUTH PACKAGE BODY
DBMS_REPCAT_AUTH PACKAGE
AQ$_SCHEDULES_PRIMARY INDEX
AQ$_SCHEDULES TABLE
如果有其它记录返回,则必须根据下面这篇文档把重复记录删除:
How to Clean Up Duplicate Objects Owned by SYS and SYSTEM Schema [ID 1030426.6]
第三部分 - 升级前工作
Step 1.
从11gR2的Oracle Home下拷贝以下文件至一个临时文件夹:
$ORACLE_HOME/rdbms/admin/utlu112i.sql
Step 2.
登陆数据库,运行:
$ sqlplus '/ as sysdba'
SQL> spool upgrade_info.log
SQL> @utlu112i.sql
SQL> spool off
SQL>
Step 3.
从下面这篇文档里可以下载到脚本dbupgdiag.sql:
Script. to Collect DB Upgrade/Migrate Diagnostic Information (dbupgdiag.sql) [ID 556610.1]
运行这个脚本:
cd $ cd $ORACLE_HOME/rdbms/admin
$ sqlplus / as sysdba
sql> alter session set nls_language='American';
sql> @dbupgdiag.sql
sql> exit
如果该脚本报告有invalid对象,运行以下命令重编译无效对象:
$ sqlplus "/ as sysdba"
SQL> @utlrp.sql
从10.2开始,CONNECT角色的权限变少了,,所以如果你是从10.2之前升级到11g的话,升级之后,需要重新授予缺少的权限,但是如果是从10.2及之后升级到11g的话,就不需要重新赋权限了,本例是从10.2.0.4升级到11g的,因此不需要该步骤。
Step 5.
生成重建dblink的脚本,以防万一数据库需要降级。和Step 4一样,本例是从10.2.0.4升级到11g的,因此不需要该步骤。

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
