Oracle 12.2.0.1应用缓存之二(缓存配置准备工作)

  1. 在ORACLE 中创建 timesten用户及内部表
[timesten@XAG8 conf]$  cd $TIMESTEN_HOME/install/oraclescripts
[timesten@XAG8 oraclescripts]$ pwd
/u01/timesten/tt181/install/oraclescripts

[timesten@XAG8 oraclescripts]$ ls
cacheCleanUp.sql  checkRAC.sql                   initCacheAdminSchema.sql  README.TXT
cacheInfo.sql     grantCacheAdminPrivileges.sql  RAC_README                ttCacheADGSiteFailover.sql

[timesten@XAG8 admin]$ sqlplus sys/123456@PDB1 as sysdba
[timesten@XAG8 oraclescripts]$ sqlplus sys/123456@PDB1 as sysdba
SQL>  select FILE_NAME from dba_data_files; 
FILE_NAME

  1. 将oracle 下的ttuser 用户作为缓存表的宿主&创建测试用表
18.1 無默認測試表的腳本
  1. 创建缓存管理用户
[timesten@XAG8 oraclescripts]$ cd $TIMESTEN_HOME/install/oraclescripts

[timesten@XAG8 oraclescripts]$  sqlplus sys/123456@PDB1 as sysdba

SQL> create user cacheadm identified by oracle default tablespace cachetblsp quota unlimited on cachetblsp;

SQL> @grantCacheAdminPrivileges "cacheadm"
  1. 配置Timesten 缓存数据库的DSN
[timesten@XAG8 oraclescripts]$  sqlplus sys/123456@PDB1 as sysdba

SQL> select value from nls_database_parameters where parameter='NLS_CHARACTERSET';
VALUE
--------------------------------------------------------------------------------
AL32UTF8

[timesten@XAG8 oraclescripts]$ cd $TIMESTEN_HOME/conf
[timesten@XAG8 conf]$ pwd
/u01/timesten/tt181/conf

[timesten@XAG8 conf]$ ttisql ttdb

Command> call ttconfiguration('DataBaseCharacterSet');
< DataBaseCharacterSet, AL32UTF8 >
  1. 在TimesTen 数据库中创建用户(缓存管理用户cacheadm,缓存用户ttuser【已创建】)
[timesten@XAG8 conf]$ ttisql ttdb

Command> create user cacheadm identified by timesten;

Command> grant create session, cache_manager, create any table, drop any table to cacheadm;
  1. 在TimesTen 数据库中设置缓存管理员账户
#将oracle 数据库中缓存管理员的用户名和密码存储在timesten中
[timesten@XAG8 conf]$ ttisql "DSN=ttdb; uid = cacheadm; pwd = timesten;OraclePWD=oracle"

Command> call ttCacheUidPwdSet('cacheadm','oracle');

#确定缓存管理用户名设置
Command> call ttCacheUidGet();
< CACHEADM >

#Testing the connectivity between the TimesTen and Oracle databases
Command> passthrough 3;
Passthrough command has set autocommit off.

Command> SELECT * FROM V$VERSION;

  1. 缓存与复制代理管理
# 查询代理运行状态
[timesten@XAG8 conf]$ ttAdmin -query ttdb | grep Started

Cache Agent Manually Started    : False

#启动缓存代理

#启动复制代理 (未定义和复制相关的缓存组,所以本次启动报错)

  1. 緩存組測試
[timesten@XAG8 conf]$ sqlplus sys/123456@PDB1 as sysdba
SQL> grant dba to ttuser;

[timesten@XAG8 conf]$ sqlplus ttuser/oracle@PDB1

#将基础表的读取权限赋予oracle的缓存管理用户
