Application Servers as Delivered

all software under the one directory


Why Change?

• Delivered structure for servers does not lend itself to easy PeopleTools upgrade

• Initial logical server structure too unpredictable

• Early tests, indicated system failure with the proposed increase

• Increased user base 40+ to 2500+ requires substantial increase in flexibility and robustness


And the GSC?

• Also the technique appears to be officially supported• 717563: WebLogic: How do I install multiple

instances of WebLogic 5.1 • 200731212: How to Start Multiple WebLogic 5.1

Instances on Windows 2000/NT as Services (SP9)• 714889 - Installing and Removing the Multiple

WebLogic NT Services • Partially correct – but use beasrv.exe

• 720177 - How to configure Weblogic for multiple NICs?


The Hardware Change - Physical Server setup

• Database Server• 2 cpu 750mgz – 3GB Mem

• Application Server

• 2 cpu Xeon 2.4 ghz – 1 GB Mem

• Web Server• 2 cpu 1.4 ghz – 2 GB Mem

• Report Server• 1 cpu Xeon 2.4 ghz – 1GB Mem


The Software

• Database – Oracle 8.1.7.4 on Solaris 8• All other servers Windows 2000• PeopleSoft HRMS 8.0 SP1• PeopleTools 8.18• SQR 8.18• Crystal 8.0

Each instance has all the software


Perceived Benefits

• Allowed us to progressively upgrade PeopleTools 8.14.10 to 8.18.x

• Different Tools versions in different environments. Permitting testing of tools versions through chain of environments.

• Substantial increase in system stability & scalability with the new structure

• Reviewed several physical/logical combinations


Configuration - Considerations

• Tuxedo

• Application Servers

• Weblogic webserver


Tuxedo

• Install on each server• One Important Configuration Consideration

• Some possible tuning opportunities


Queue and Maximum Message Size

• Typical Tuxedo Message ~100Kb• If message > ¾ of message queue/max

message size then written to disk• This is slow

• Provide room for queuing• Recommend at least 256Kb

• See 8.4 Red Paper for on-line performance


Number of Message Queues

• Number of queues =

2 * (

PSAPPSRV + PSQCKSRV + PSQRYSRV + PSSAMSRV + PSDBGSRV + PSPUB*)

+ 7

• (More server types in 8.4).


Tuxedo – IPC settings


Weblogic Issues

• Only one Windows Webserver• Used for Dev, Test and Production

• On Windows, only one Weblogic installation per Weblogic version.

• Want to run different PeopleTools versions on same Weblogic installation – how to upgrade?


Weblogic Server

• Only one Weblogic server per physical windows server because of use of registry.

• These would be environmental variables on Unix.


How to create a copy of myserver – part 1

• Copy the entire myserver directory to myserver_newserver

• Amend the Weblogic.properties for the new server

• Rename the directory in \psftdocs to the new server (say newserver)

• Amend the configuration.properties within this directory


How to create a copy of myserver – part 2

• Rename the directory under public_html to the new server (say newserver)

• Amend the signon.html within this directory• Delete access.log & other log files from

myserver_newserver directory


Weblogic SP9

• Required in order to support multiple NT services.

• BEA Documentation uncharacteristically contradictory• beasvc.exe instead of install.exe and remove.exe


Multiple Application Servers

• Two new servers for Application Servers.• Still need different PeopleTools versions on

each servers• Multiple %PS_HOME%

• Only one Tuxedo installation per Windows server• One configuration to support all domains

•Application Servers and Process Schedulers under Tuxedo


Multiple Application Servers

• One PeopleTools version per %PS_HOME%• Need to set this variable before running

psadmin


PIA Install quirks

• PIA Location

• Weblogic NT Services


Weblogic NT Services

• PeopleSoft PIA Installation process only creates service that runs default myserver

• Don’t run myserver, use it as a template only


Create NT Service per Web Server

• Used beasvc.exe to create and delete NT services for each Weblogic server.• Introduced at SP9• Do not use install.exe and remove.exe (up

to SP8)• If you have to delete a service you will

probably have to reboot the Windows server because the service table will lock.


First, do it without a service

• Get the various web servers starting from just an ordinary batch script.• Get the environmental variables for the

JVM right.• The put those variables into script to create

service.


installNtServiceXXXX.cmd Part 1 of 3

set MYSERVER=myserverXXXXset JAVA_HOME=C:\PROGRA~1\JavaSoft\

JRE\132DB1~1.1_0set WEBLOGICHOME=d:\ps\weblogic51set CLASSPATH=%WEBLOGICHOME%\lib\

weblogic510spboot.jar;%WEBLOGICHOME%\classes\boot;%WEBLOGICHOME%\eval\cloudscape\lib\cloudscape.jar

…



• This is variable comes from the batch script.

How the services should look


PIA Location

• No matter what you specify for the location the servlet files go to myserver!• (PT8.18.10)

• So don’t actually use myserver• Use it as a template


Upgrading Tools for Weblogic – Part 1 of 2

• Install the websever changes into myserver• Copy the following 3 directories from

myserver to myserver_newserver structure• Clientclass• Serverclasses• servletclasses


Upgrading Tools for Weblogic – Part 2 of 2

• Backup Weblogic.properties, configuration.properties, signon.html to compare with new files for changes

• Copy all files from myserver\psftdocs to target server

• Copy all files from i to target server• Rebuild Configuration files from scratch &

compare to backups


Upgrading

• You can move an upgrade between different versions of PeopleTools• Do in 2-tier mode• Can connect to different patch releases

• 8.18.xx (may not be supported)

• If different minor releases go via file• 8.14 -> 8.18• Just like a PSFT patch!

• Thus Application upgrades can overtake PeopleTools upgrade.


Other bits

• Tuxedo and Terminal Services• Don’t• Can’t start a server when a TS window open

• Multiple NIC’s• Different IP address and/or different ports• Load balance across IP address

• even on same network card • and on same physical NT server• Hence multiple JVM without Weblogic clusters


Finally

• Questions?
