修改limits.conf
1.echo "* hard nofile 8192" >> /etc/security/limits.conf
2.echo "* soft nofile 8192" >> /etc/security/limits.conf 2. 新建timsten用户
1.groupadd -g 600 timesten
2. useradd -g 600 -u 600 timesten
3. passwd timesten
3. 安装
首先安装JDK(64位系统需安装JDK 64版本)
1.[root@flypig timesten]#mkdir /etc/TimesTen/
2. [root@flypig timesten]#chown timesten:timesten /etc/TimesTen/
3. su – timesten
4. cd $TIMESTEN_PRODUCT
5. ./setup.sh
6. Please choose an instance name for this installation? [ tt70 ]
7. Timesten版本选择:安装AMD64和Intel EM64的版本
8. Timesten产品选择:Oracle TimesTen In-Memory Database
9. Timesten组件选择:Client/Server and Data Manager
10.安装目录:/opt
11.是否打开 access control:yes
12. daemon log位置:/opt/TimesTen/log
13.没有特别说明的部分,都默认回车
14.
4. 环境配置
在/home/timesten/.bash_profile中添加以下行(SUSE9下面是.profile)
1.. /opt/TimesTen/tt70/bin/ttenv.sh
2.export JAVA_HOME=/opt/java
5. 增加数据库用户
1.[timesten@flypig timesten]$ source ~timesten/.profile
2. [timesten@flypig]$ttisql TT_tt70
3. Command> create user tt_test identified by 'tt_test';
4. Command> grant ddl,admin to tt_test;
5. Command> grant write to tt_test;
6. Command> grant SELECT to tt_test;
7. Command> quit
6. 增加用户DSN
1.[timesten@flypig timesten]$mkdir –p /opt/TimesTen/imdb
2. [timesten@flypig timesten]$vi /opt/TimesTen/tt70/info/sys.odbc
.ini
3.在 [ODBC Data Sources]下面增加:
4. imdb=TimesTen 7.0 Driver
5.在最后面增加:
6. [imdb]
7. Driver=/opt/TimesTen/tt70/lib/libtten.so
8. DataStore=/opt/TimesTen/imdb/imdb
9. DatabaseCharacterSet=US7ASCII
10. Authenticate=0
11. UID=tt_test
12. PWD=tt_test
13. #ipcs memory size(M),该内存大小必须比shmmax小,否则用户DSN会进不

14. PermSize=5000
15. Connections=2047
16. #permsize*20%
17. TempSize=1000
18. CkptFrequency=600
19. CkptLogVolume=256
20. LogBuffSize=256000
21. LogFileSize=256
22.测试用户DSN:
23. [timesten@flypig timesten]$ttisql imdb
24.连接成功出现command命令行则配置没有问题!
25.
7. 数据对象安装
1.[timesten@flypig timesten]$ttisql imdb
2. Command> 执行标准SQL语句
3.或者:将SQL语句写在文本里,如imdb.schema.20070507
4.执行ttisql –f imdb.schema.20070507
8. Active/Standby数据库配置
1) 在另外台服务器上安装新的一套Timesten,配置同上,两台Timesten记为Timesten1和Timesten2,准备将Timesten1为Active,Timesten2为Standby
2) 在/etc/hosts里面加入各台Timesten
3) 同步Timesten1和Timesten2的时间,最好用ntp之类的定时(20分钟)同步一下时钟,否则replication就会失败
4) 在Timesten1上安装好所有的用户数据库对象
5) 创建replication的schema
1.[timesten@Timesten1 timesten]$ttisql imdb
2. Command> create active standby pair
3. IMDB on "Timesten1", IMDB on " Timesten2"
4. store IMDB on " Timesten1"
5. port 20000
6. store IMDB on " Timesten2"
7. port 21000;
说明:
Timesten1、Timesten2为hostname
IMDB为用户DSN
6) 将Timesten1置为active,启动replication agent
1.[timesten@Timesten1 timesten]$ttisql imdb
2. Command> call ttRepStateSet(‘active’);
3. [timesten@Timesten1 timesten]ttAdmin –repStart imdb
7) 退出连到imdb(Timesten2)的所有连接,从imdb(Timesten1)复制数据库
1.[timesten@Timesten2 timesten]$ ttRepAdmin -duplicate -from imdb
-host timesten1 -UID tt_test -PWD tt_test imdb
2.如果出现imdb为in use错误,用ttDestory删除imdb,再试
3. [timesten@Timesten2 timesten]$ ttDestroy imdb
8) 启动Timesten2的replication agent
[timesten@Timesten2 timesten]$ ttAdmin –repStart imdb
9) 检查状态
1.[timesten@Timesten1 timesten]$ ttisql imdb
2. Command> call ttRepStateGet;
3. < ACTIVE >
4.
5.[timesten@Timesten2 timesten]$ ttisql imdb
6. Command> call ttRepStateGet;
7. < STANDBY >
8.
9.[timesten@timesten2 timesten]$ ttRepAdmin -showstatus imdb

9. 客户端安装
参考以上服务器的安装过程,安装组件选择:[3] Client Only,配置ODBC:
1) 在sys.ttconnect.ini增加Timesten Server
1.[timesten@flypig timesten]$ vi /opt/TimesTen/tt70/info/sys.ttco
nnect.ini
2.增加Timesten Server:
3. [imdb]
4. Description=TimesTen Server
5. Network_Address=10.2.0.99
6. TCP_PORT=17003
默认情况下,64位Timesten的port是17003,32位试17002
2) 在sys.odbc.ini增加DSN配置
1.[timesten@flypig timesten]$ vi /opt/TimesTen/tt70/info/sys.odbc
.ini
2.增加DSN:
3. [imdb]
4. TTC_SERVER=imdb
5. TTC_SERVER_DSN=imdb ######这个为服务端的DSN########
SERVER就是我们上面配的Timesten Server
3) 在客户机的profile中增加:
1.[timesten@flypig timesten]$ vi .profile
2.
3.. /opt/TimesTen/tt70/bin/ttenv.sh
4) 测试配置:
[timesten@flypig timesten]$ ttisqlcs imdb
ttisql在自身服务器上使用,ttisqlcs在客户机上使用
10. 常用命令列表
/opt/TimesTen/tt70/startup/tt_tt70:Timesten起停
ttSize:计算表大小,如 ttSize -tbl tt_ref imdb
ipcs:共享内存查看
ttAdmin –repStop:停replication agent,如 ttAdmin –repStop imdb
ttAdmin –repStart:起replication agent,如 ttAdmin –repStart imdb
drop ACTIVE STANDBY PAIR:删除replication配置,ttisql命令
ttRepAdmin -showconfig:显示repliation配置信息,如ttRepAdmin –showconfig imdb
ttRepAdmin -showstatus:显示repliation配置信息,如ttRepAdmin –showstatus imdb
CALL ttRepStateSet('ACTIVE');:Replication状态置为active,ttisql命令ttDestroy:删除用户DSN所有数据,如ttDestroy imdb
ttRepAdmin -duplicat:数据库之间复制,如ttRepAdmin -duplicate -from imdb1 -host timesten1 -UID tt_test -PWD tt_test imdb2
ALTER ACTIVE STANDBY PAIR:加复制表,standby机子需要重新复制数据库,如ALTER ACTIVE STANDBY PAIR
INCLUDE TABLE tab1 ttisql
call ttRepStateGet; :获取Replication状态(active/standby),ttisql命令ttDaemonLog:Timesten的日志查看,-f可以tail日志
tables 显示数据库表,ttisql命令
ttAdmin -ramPolicy:修改ram策略,如 ttAdmin -ramPolicy always imdb ttAdmin -repPolicy:修改replication策略,如 ttAdmin -repPolicy always imdb
11. 已知问题和处理方法
Replication失效:
1) 确认各台机子的replication agent都在,可以用ttRepAdmin –showstatus命令
2) 确认两台主机的时间一致,不一样的话日志中会有错误信息:
ttDaemonLog | grep Err
17:13:27.61 Err : REP: 12368: IMDB1:transmitter.c(5752): TT16224: Transmitter thread failure due to high clock skew 943 with peer store IMDB3
无法在netapp上使用Timesten
1) mount参数加exec
2) 修改/opt/TimesTen/tt70/info/ttendaemon.options,在里面加
-allowNetworkFiles。
