删除读写缓存组, 写缓存组删除前必须停止复制代理：

$ ttisql "uid=cacheadm;pwd=timesten;dsn=ttdb;oraclepwd=oracle"
Command> cachegroupsCache Group CACHEADM.READCACHE:Cache Group Type: Read OnlyAutorefresh: YesAutorefresh Mode: IncrementalAutorefresh State: OnAutorefresh Interval: 5 SecondsAutorefresh Status: okAging: No aging definedRoot Table: ORATT.READTABTable Type: Read OnlyCache Group CACHEADM.WRITECACHE:Cache Group Type: Asynchronous Writethrough (Dynamic)Autorefresh: NoAging: LRU onRoot Table: ORATT.WRITETABTable Type: Propagate2 cache groups found.Command> drop cache group readcache;
Command> drop cache group writecache;5245: The operation cannot be executed while the Replication Agent for this database is running.
The command failed.Command> call ttrepstop();
Command> drop cache group writecache;Command> call ttcachestop();
10021: Cache agent was not stopped due to cache agent policy setting.
The command failed.

停止缓存代理出错，是因为policy设置成了always：

$ ttadmin ttdb
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : always
Cache Agent Manually Started    : True
Database State                  : Open

将cache policy修改为manual:

$ ttadmin -cachepolicy manual ttdb
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : True
Database State                  : Open

确认缓存代理和复制代理未运行：

删除数据库，首先需要断开所有的客户端连接。

查看到有一个来自10.0.0.2的连接，实际上是Windows上安装的SQL Developer，在SQL Developer中断开连接就好了：

$ ttstatus

...

以下删除数据库，删除前请做好数据库备份：

[oracle@ttserver ~]$ ttdestroy ttdb
Failed to destroy data store: TT0839: Cannot access database because it is in use. A database may be considered to be in use due to its RAM Policy setting, even though there are no active connections to it. -- file "db.c", lineno 6078, procedure "sbDbDestroy"
[oracle@ttserver ~]$ ttadmin ttdb
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False
Database State                  : Open
[oracle@ttserver ~]$ ttadmin -rampolicy manual ttdb

Cache Agent Manually Started    : False
Database State                  : Closed
[oracle@ttserver ~]$ ttdestroy ttdb

确保所有数据库都已删除。

现在还有timesten守护进程在运行：

$ ttstatus
TimesTen status report as of Mon Dec 21 02:26:08 2020Daemon pid 2060 port 6624 instance tt181
TimesTen server pid 2067 started on port 6625
------------------------------------------------------------------------

End of report[oracle@ttserver ~]$ ttstatus
ttStatus: Could not connect to the TimesTen daemon.

by running "ttDaemonAdmin -start".
/home/oracle/tt181/info/daemon.status says:
2020-12-21 02:27:37 daemon shutting down due to user request

最后删除timesten实例和软件：

$ ttinstancedestroy** WARNING **The uninstallation has been executed by a non-root user.If the TimesTen daemon startup scripts were installed,you must run $TIMESTEN_HOME/bin/setuproot -uninstallto remove them. If you proceed with this uninstallation, youwill have to remove the startup scripts manually.** WARNING **All files in the directory:/home/oracle/tt181will be removed, including any file that you or other usersmay have created.Are you sure you want to completely remove this instance?

The TimesTen instance tt181 has been destroyed.$ chmod -R 750 /u01/installation/tt18.1.4.1.0/
$ rm -rf /u01/installation/tt18.1.4.1.0/

还剩instance admin用户没删，略。
