CC7.1CMServer性能调优

 

IBM Rational ClearCase v7.1的CM Server，可以进行如下方面的性能调优。

 

•1.        WAS调优

1.1 调整WAS中的channelwrite类型为sync

(1) 启动WAS admin console:

http://<host>:12060/ibm/console

(2)在Admin Console中进行如下操作

Servers -> Application Servers -> serverName -> Web Container Settings -> Web Container -> Custom Properties:

   按新建:

   增加如下值对:

   名称: com.ibm.ws.webcontainer.channelwritetype

   值: sync

   按确定，然后保存配置.

(3) 重新启动WAS进程      

如需更多信息，请参考WAS TechNote http://www-01.ibm.com/support/docview.wss?uid=swg21317658

 

1.2 调整JVM和线程池（Thread Pool）设置

(1) 启动WAS admin console:

http://<host>:12060/ibm/console

(2) 调整JVM设置

Parameter Name

Suggested Value

Location

JVM heap size of the application server

min=1024 MB, max=1024 MB

Servers->Application Servers->Server1->Process Definition>Java JVM

(3) 调整Thread Pool设置

Parameter Name

Suggested Value

Location

Default thread pool of the application server

min=200, max=400

Servers->Application Servers-> server1 -> Thread Pool-> Default

"Web container" thread pool of the application server

min=200, max=400

Servers->Application Servers-> server1 -> Thread Pool ->WebContainer

 

•2．  设置CM Server MBean属性

 

serverThresholdCount = 200

maxServerCount = 300

 

如需设置上述属性，需要在命令窗口中参照下面命令进行设置

>cd C:/Program Files/ibm/RationalSDLC/common/CM/scripts

>C:/Program Files/ibm/RationalSDLC/common/CM/scripts>"c:/Program Files/ibm/RationalSDLC/common/eWAS/bin/wsadmin.bat"

 

wsadmin>source teamAdminUtils.jacl

wsadmin>set t [getTeamServer]

wsadmin>set cc [$AdminControl getAttribute $t ccServerFactory]

wsadmin>$AdminControl setAttribute $cc maxServerCount 300

wsadmin>$AdminControl setAttribute $cc serverThresholdCount 200

 

wsadmin>$AdminControl getAttributes $cc maxServerCount

wsadmin>$AdminControl getAttributes $cc serverThresholdCount

 

3.   CM Server的Windows注册表

 

Parameter Name

Suggested Value

Location

Note

LockMgrCmdLine

-a almd -f 1024 -u 1024 -q 4096

HKEY_LOCAL_MACHINE/SOFTWARE/Atria/ClearCase/CurrentVersion/LockmgrCmdLine

 

On Linux VOB:

/var/adm/rational/clearcase/config/lockmgr.conf

LOCKMGR_OPTS = -u 1024 -q 4096

This should apply on VOB Server

total desktop heap size

96 (or bigger)

HKeyLocalMachine/SYSTEM/CurrentControlSet/Control/Session Manager/Memory Management/SessionViewSize

non-interactive desktop heap size

1024 K

For 64 bit machines, 2048 or 1024 as needed.

HKeyLocalMachine/SYSTEM/CurrentControlSet/Control/Session Manager/SubSystems

4.     WAS service logon

确保 选中了"允许服务与桌面交互"  (在Windows的服务面板中)
