oracle timesten tt的启动与停止

一、TT的启停
停服务：
1、停止复制与cache 进程；
2、停掉server进程；
3、卸载内存（对于RAM为手动管理的）

4、停掉 Daemon

启动反之。

二、启动实战。

1、起tt主守护进程：

ocs1节点：

ttdaemonadmin -start

tt@ocs1[/tt]$ttdaemonadmin -start
TimesTen Daemon startup OK.

ocs2节点：

tt@ocs2[/tt]$ttdaemonadmin -start
TimesTen Daemon startup OK.

此时查看tt状态：

tt@ocs1[/tt]$ttstatus
TimesTen status report as of Tue Jun  5 11:00:51 2018

Daemon pid 3384 port 53396 instance tt11
TimesTen server pid 3393 started on port 53397
------------------------------------------------------------------------
Data store /tt/DS/ocs
There are no connections to the data store
RAM residence policy: Manual
Data store is manually unloaded from RAM
Replication policy  : Manual
Cache Agent policy  : Manual
PL/SQL enabled.
------------------------------------------------------------------------
Accessible by group tt
End of report

没有任何进程信息，可以看到，daemon进程会自动启动tt server进程。

2、装载DS到内存：

ttadmin -ramload ocs

ocs1执行：

tt@ocs1[/tt]$ttadmin -ramload ocs
RAM Residence Policy            : manual
Manually Loaded In RAM          : True
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False

ocs2执行：

tt@ocs2[/tt]$ttadmin -ramload ocs
RAM Residence Policy            : manual
Manually Loaded In RAM          : True
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False

3、更改加载内存策略为always：

ttadmin -rampolicy always ocs

ocs1执行

tt@ocs1[/tt]$ttadmin -rampolicy always ocs
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False

ocs2执行：

tt@ocs2[/tt]$ttadmin -rampolicy always ocs
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False

4、启动replication复制进程：

ttadmin -repstart ocs

ocs1执行：

tt@ocs1[/tt]$ttadmin -repstart ocs
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : True
Cache Agent Policy              : manual
Cache Agent Manually Started    : False

ocs2执行：

tt@ocs2[/tt]$ttadmin -repstart ocs
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : True
Cache Agent Policy              : manual
Cache Agent Manually Started    : False

5、更改复制进程策略为always：

ttadmin -reppolicy always ocs

ocs1节点执行：

tt@ocs1[/tt]$ttadmin -reppolicy always ocs
RAM Residence Policy            : always
Replication Agent Policy        : always
Cache Agent Policy              : manual
Cache Agent Manually Started    : False

ocs2节点执行：

tt@ocs2[/tt]$ttadmin -reppolicy always ocs
RAM Residence Policy            : always
Replication Agent Policy        : always
Cache Agent Policy              : manual
Cache Agent Manually Started    : False

5、验证复制是否正常：

ocs1执行：

tt@ocs1[/tt]$ttisql ocs

Copyright (c) 1996, 2015, Oracle and/or its affiliates. All rights reserved.
Type ? or "help" for help, type "exit" to quit ttIsql.



connect "DSN=ocs";

1 row inserted.
Command> select * from test01 ;
< 1 >
< 2 >
< 3 >
< 4 >
4 rows found.
Command>

在ocs2上查看是否已经复制：

tt@ocs2[/tt]$ttisql ocs

Copyright (c) 1996, 2015, Oracle and/or its affiliates. All rights reserved.
Type ? or "help" for help, type "exit" to quit ttIsql.



connect "DSN=ocs";
Connection successful: DSN=ocs;UID=tt;DataStore=/tt/DS/ocs;DatabaseCharacterSet=TIMESTEN8;ConnectionCharacterSet=TIMESTEN8;AutoCreate=0;LogFileSize=40;DRIVER=/tt/TimesTen/tt11/lib/libtten.so;PermSize=32;TempSize=37;LockWait=1;CkptRate=40;CkptFrequency=300;CkptLogVolume=0;PrivateCommands=1;RecoveryThreads=3;TypeMode=0;LogBufMB=40;LogBufParallelism=5;
(Default setting AutoCommit=1)
Command> select * from test01 ;
< 1 >
< 2 >
< 3 >
< 4 >
4 rows found.
Command>

复制正常，可以在ocs2插入看ocs1是否正常同步：

tt@ocs2[/tt]$ttisql ocs

Copyright (c) 1996, 2015, Oracle and/or its affiliates. All rights reserved.
Type ? or "help" for help, type "exit" to quit ttIsql.



connect "DSN=ocs";
Connection successful: DSN=ocs;UID=tt;DataStore=/tt/DS/ocs;DatabaseCharacterSet=TIMESTEN8;ConnectionCharacterSet=TIMESTEN8;AutoCreate=0;LogFileSize=40;DRIVER=/tt/TimesTen/tt11/lib/libtten.so;PermSize=32;TempSize=37;LockWait=1;CkptRate=40;CkptFrequency=300;CkptLogVolume=0;PrivateCommands=1;RecoveryThreads=3;TypeMode=0;LogBufMB=40;LogBufParallelism=5;
(Default setting AutoCommit=1)
Command> select * from test01 ;
< 1 >
< 2 >
< 3 >
< 4 >
4 rows found.
Command> insert into test01 values(5); 
1 row inserted.
Command> select * from test01 ;
< 1 >
< 2 >
< 3 >
< 4 >
< 5 >
5 rows found.
Command>

在ocs1上查看是否同步：

tt@ocs1[/tt]$ttisql ocs

Copyright (c) 1996, 2015, Oracle and/or its affiliates. All rights reserved.
Type ? or "help" for help, type "exit" to quit ttIsql.



connect "DSN=ocs";
Connection successful: DSN=ocs;UID=tt;DataStore=/tt/DS/ocs;DatabaseCharacterSet=TIMESTEN8;ConnectionCharacterSet=TIMESTEN8;AutoCreate=0;LogFileSize=40;DRIVER=/tt/TimesTen/tt11/lib/libtten.so;PermSize=32;TempSize=37;LockWait=1;CkptRate=40;CkptFrequency=300;CkptLogVolume=0;PrivateCommands=1;RecoveryThreads=3;TypeMode=0;LogBufMB=40;LogBufParallelism=5;
(Default setting AutoCommit=1)
Command> select * from test01 ;
< 1 >
< 2 >
< 3 >
< 4 >
< 5 >
5 rows found.
Command>

ok。双向复制都正常。

三、停tt实战。

1、停replication代理。

在使用ttamdin -repstop ocs停代理进程之前，需要先把复制策略改为手动manual，否则直接停会报错：

tt@ocs1[/tt]$ttadmin -repstop ocs
*** [TimesTen][TimesTen 11.2.2.8.0 ODBC Driver][TimesTen]TT10016: Replication Agent was not stopped due to repPolicy setting. 
*** ODBC Error = S1000, TimesTen Error = 10016

咱们可以看下错误码10016是什么意思。

10016 Replication Agent was not
stopped due to repPolicy
setting
An attempt has been made to stop a
replication agent for a database, but the
replication policy is set to "always." See
"Starting and stopping the replication
agents" in the Oracle TimesTen In-Memory
Database Replication Guide for information on
setting the replication policy.

意思就是复制策略是always的情况下，不允许停复制进程。

咱们先改为manual后在停：

ttadmin -reppolicy manual ocs

ocs1节点执行：

tt@ocs1[/tt]$ttadmin -reppolicy manual ocs
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : True
Cache Agent Policy              : manual
Cache Agent Manually Started    : False
tt@ocs1[/tt]$

然后在停replication进程：

ttadmin -repstop ocs

tt@ocs1[/tt]$ttadmin -repstop ocs
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False
tt@ocs1[/tt]$

然后在节点ocs2上执行一遍：

tt@ocs2[/tt]$ttadmin -reppolicy manual ocs
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : True
Cache Agent Policy              : manual
Cache Agent Manually Started    : False
tt@ocs2[/tt]$ttadmin -repstop ocs
RAM Residence Policy            : always
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False
tt@ocs2[/tt]$

2、停掉server进程

ocs1上执行：

ttdaemonadmin -stopserver

tt@ocs1[/tt]$ttdaemonadmin -stopserver
TimesTen Server stopped.
tt@ocs1[/tt]$

ocs2上执行：

tt@ocs2[/tt]$ttdaemonadmin -stopserver
TimesTen Server stopped.
tt@ocs2[/tt]$

3、卸载内存：

ttadmin -ramUnload ocs

tt@ocs1[/tt]$ttadmin -ramUnload ocs
ttAdmin: TimesTen Error: 10010; RAM unload ignored due to ramPolicy setting
tt@ocs1[/tt]$

看看官方文档怎么说：

意思就是你不能在设置了内存管理策略是always的情况下去卸载内存。要设置成manual。

按他说的来。

ttadmin -ramPolicy manual ocs

ocs1执行内存策略为manual。

tt@ocs1[/tt]$ttadmin -ramPolicy manual ocs
RAM Residence Policy            : manual
Manually Loaded In RAM          : True
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False
tt@ocs1[/tt]$

ocs2执行：

tt@ocs2[/tt]$ttadmin -ramPolicy manual ocs
RAM Residence Policy            : manual
Manually Loaded In RAM          : True
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False
tt@ocs2[/tt]$

然后卸载内存：

ttadmin -ramunload ocs

ocs1执行：

tt@ocs1[/tt]$ttadmin -ramunload ocs
RAM Residence Policy            : manual
Manually Loaded In RAM          : False
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False
tt@ocs1[/tt]$

ocs1执行：

tt@ocs2[/tt]$ttadmin -ramunload ocs
RAM Residence Policy            : manual
Manually Loaded In RAM          : False
Replication Agent Policy        : manual
Replication Manually Started    : False
Cache Agent Policy              : manual
Cache Agent Manually Started    : False
tt@ocs2[/tt]$

4、停daemon主进程。

ttdaemonadmin -stop

ocs1执行：

tt@ocs1[/tt]$ttdaemonadmin -stop
TimesTen Daemon stopped.
tt@ocs1[/tt]$

ocs2执行：

tt@ocs2[/tt]$ttdaemonadmin -stop
TimesTen Daemon stopped.
tt@ocs2[/tt]$

到此tt的启停就都演示完了。
