TimesTen 安装 - Linux prerequisites Semaphores
Shared memory
To increase the shared memory size to 2048 MB, log in as root and edit the
/etc/sysctl.conf file by adding the line:
kernel.shmmax=2147483648
If your configuration is greater than 8 GB, you should also increase the value of the
shmall parameter. The value is in KB and should be equal to
ceil(SHMMAX/PAGE_SIZE). Page size is generally 4K on x86 systems and 16K on
Itanium. For example, for a 64 GB database on Itanium, you should specify the
following parameters values:
kernel.shmmax=68719476736
kernel.shmall=4194304
如果是x86系统，共享内存是1GB，（shmall = shmmax/4KB）,则参数设置为：
# 1GB
kernel.shmmax = 1073741824
# 1 * 1024 * 1024KB/4KB=262144
kernel.shmall = 262144
【重要的配置文件】
TimesTen根路径在/home/tt/TimesTen/tt1122（tt为用户）下
1./etc/sysctl.conf 配置和内存等相关的先决条件，我认为主要是内存
2.sys.odbc.ini（/home/tt/TimesTen/tt1122/info/sys.odbc.ini） 配置ODBC数据源、Server DSN、User DSN等
3.sys.ttconnect.ini（/home/tt/TimesTen/tt1122/info/sys.ttconnect.ini） 配置User DSN要连接的服务器的IP和PORT，用在sys.odbc.ini中的User DSN
4..bash_profile（/home/tt/.bash_profile,前面有个【.】） 配置用户tt的启动参数。如一些tt需要的环境变量。

The instance name must be a non-null alphanumeric string, not longer than 255 characters.Please choose an instance name for this installation? [ tt1122 ] Instance name will be 'tt1122'.Is this correct? [ yes ] yesOf the three components: [1] Client/Server and Data Manager [2] Data Manager Only [3] Client OnlyWhich would you like to install?

[ 1 ] Where would you like to create the daemon home directory? [ /home/tt/TimesTen/tt1122/info ] The daemon logs will be located in /home/tt/TimesTen/tt1122/infoWould you like to specify a different location for the daemon logs? [ no ] yesWhere would you like the daemon logs to be written? [ /home/tt/TimesTen/tt1122/info ] Installing into /home/tt/TimesTen/tt1122 ...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 53396.Do you want to use the default port number for the TimesTen daemon? [ yes ] yesThe daemon will run on the default port number (53396).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 'tt'? [ yes ] yesNOTE: Enabling PL/SQL will increase the size of some TimesTen libraries.Would you like to enable PL/SQL for this instance? [ yes ] yesIn order to use the 'In-Memory Database Cache' feature in any databasescreated within this installation, you must set a value for the TNS_ADMINenvironment variable. It can be left blank, and a value can be supplied laterusing <install_dir>/bin/ttModInstall.Please enter a value for TNS_ADMIN (s=skip)? [ ] sNOTE: It appears that you are running version 4 or higher 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 <install_dir>/lib directory and to the 4.1.0 server binary in the <install_dir>/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? [ 53397 ] Do you want to install QuickStart and the TimesTen Documentation? [ no ] yesWhere would you like to install the quickstart and doc directories (s=skip)? [ /home/tt/TimesTen/tt1122 ] The TimesTen Quickstart applications can take up to 64 Mbytes of disk space.Depending on how your system is configured, you may not want to create theQuickStart DemoDataStore directory in the default location,/home/tt/TimesTen/tt1122/info/DemoDataStoreWhere would you like to create the DemoDataStore directory?
