Linux下TimesTen主備搭建、重建cache group、重建備機操作
整個過程都比較簡單，這裡也就都不加描述了，適合初學者做為參考。

NOTE: Each TimesTen installation is identified by a unique instance name.
The instance name must be a non-null alphanumeric string, not longer than 255 characters.
Please choose an instance name for this installation? [ tt1121 ]
Instance name will be 'tt1121'.
Is this correct? [ yes ]
Of the three components:
[1] Client/Server and Data Manager
[2] Data Manager Only
[3] Client Only
Which would you like to install? [ 1 ]
Of the following options :
[1] /home/timesten
[2] /Timesten
[3] Specify a location
[q] Quit the installation
Where would you like to install the tt1121 instance of TimesTen? [ 1 ]
Where would you like to create the daemon home directory? [ /home/timesten/TimesTen/tt1121/info ] /Timesten/tt11/info
The daemon logs will be located in /Timesten/tt11/info
Would you like to specify a different location for the daemon logs? [ no ] yes
Where would you like the daemon logs to be written? [ /Timesten/tt11/info ] /Timesten/tt11/logs
Are you sure you want the daemon logs to be written to /Timesten/tt11/logs? [ yes ]

Creating /home/timesten/TimesTen/tt1121 ...
Uncompressing ...
NOTE: If you are configuring TimesTen for use with Oracle Clusterware, the daemon port number must be the same across all TimesTen installations managed within the same Oracle Clusterware cluster.
NOTE: All installations that replicate to each other must use the same daemon port number that is set at installation time. The daemon port number can be verified by running 'ttVersion'.
The default port number is 53388.
Do you want to use the default port number for the TimesTen daemon? [ yes ]
The daemon will run on the default port number (53388).
NOTE: For security, we recommend that you restrict access to the
TimesTen installation to members of a single OS group. Only members of that OS group will be allowed to perform direct mode connections to TimesTen, and only members of that OS group will be allowed to perform operations that access TimesTen data stores, TimesTen files and shared memory. The OS group defaults to the primary group of the instance administrator. You can default to this group, choose another OS group or you can make this instance world-accessible. If you choose to make this instance world-accessible, all database files and shared memory are readable and writable by all users.
Restrict access to the the TimesTen installation to the group 'timesten'? [ yes ]
NOTE: Enabling PL/SQL will increase the size of some TimesTen libraries.
Would you like to enable PL/SQL for this instance? [ yes ] no
PL/SQL will not be enabled. It can be enabled later by running
/home/timesten/TimesTen/tt1121/bin/ttmodinstall.
In order to use the 'In-Memory Database Cache' feature in any databases
created within this installation, you must set a value for the TNS_ADMIN
environment variable. It can be left blank, and a value can be supplied later
using/bin/ttModInstall.
Please enter a value for TNS_ADMIN (s=skip)? [ ] s
NOTE: It appears that you are running version 4.1 of the g++ compiler. TimesTen ships with multiple sets of client libraries and server binaries : one built for compatibility with g++ 3.4.6 and one with g++ 4.1.0. The installer has created links to the 4.1.0 library in the/lib directory and to the 4.1.0 server binary in the /bin directory. If you want to use a different compiler, please modify the links to point to the desired library and server binary.
Installing server components ...
What is the TCP/IP port number that you want the TimesTen Server to listen on? [ 53389 ]
Do you want to install QuickStart and the TimesTen Documentation? [ no ]
Would you like to install the documentation (without QuickStart)? [ yes ] no
Installing client components ...
Would you like to use TimesTen Replication with Oracle Clusterware? [ no ]
NOTE: The TimesTen daemon startup/shutdown scripts have not been installed.
Run the 'setuproot' script :
cd /home/timesten/TimesTen/tt1121/bin
./setuproot -install
This will move the TimesTen startup script into its appropriate location.
The startup script is currently located here :
'/home/timesten/TimesTen/tt1121/startup/tt_tt1121'.
The documentation was not installed.
To manually install the documentation, run the command 'setup.sh -installDoc'
The 11.2.1.8 Release Notes are located here :
'/home/timesten/TimesTen/tt1121/README.html'
Starting the daemon ...
TimesTen Daemon startup OK.
End of TimesTen installation.
