Understanding peoplesoft architecture

I have written article specially for new peoplesoft dbas who most of time try to figure out how to find the details regarding a peoplesoft application. Peoplesoft application consists of database server, application server and webserver. Batch server is also present for reporting purposes.
Lets follow the top down approach and assume that you have been given a URL and are asked to find all the peoplesoft application details from it. (We are assuming you have access to all the servers and your application has a simple configuration with one webserver,one application server and one database server.)

Webserver details
URL: http://delta1:8101/psp/prod/?cmd=login

Information to gather:
  • Server name hosting our webserver    : delta1
  • Port no. on which PIA is running        : 8101
  • Peoplesoft Website name                   : prod

Log into webserver(delta1 in our case) and enter the following command.
# ps -ef|grep 8101

psoft  385244       1   0   May 18      - 17:08 java -Xms256m -Xmx256m -Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0 -Dweblogic.Chunksize=65536 -Djava.util.logging.config.file=/psoft/weblogic/web849/psoft8101/webserv/GHRMS/applications/peoplesoft/ -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.Jdk14Logger -Dweblogic.Name=WebLogicAdmin -Dps_vault=/psoft/weblogic/web849/psoft8101/webserv/GHRMS/psvault -Dweblogic.ProductionModeEnabled=true -Dssl.debug=false -Dps_home=/psoft/weblogic/web849/psoft8101 weblogic.Server

Information to gather from it:
  • Owner/User of the process: psoft
User shown above has rights to start and shutdown the application. If you plan to stop/start the application you need to be logged in as this user, unless you plan to use root user to administer it.
  • Location from where it is running: /psoft/weblogic/web849/psoft8101/webserv/GHRMS/applications/peoplesoft/
Above path tells you the place where your website is installed which is our webserver home.

Application Server details
cd to webserver path noted in step2
cd /psoft/weblogic/web849/psoft8101/webserv/GHRMS/applications/peoplesoft/
and enter the following command.

# find ./ -name

Now get the peoplesoft website name which we noted down in the first step. In our case it's 'prod'. Now we need to open the configuration file related to it.

Enter the following command.

# more ./PORTAL/WEB-INF/psftdocs/prod/

Now that we have opened the configuration  file we'll get the appserver details from it. Parameter psserver will provide you with the application server details. It would be similar to
(To keep things simple we are considering the case of one appserver connected to one webserver)

Information to gather:
  • Application Server name     : appserver1
  • JSL Port                             : 9010

Log into appserver and enter the following command.
# ps -ef|grep 9101
   psoft  679954       1   0   May 31      -  0:29 JSL -C dom=PROD_56831 -g 95 -i 200 -u appserver1 -U /psoft/pt849/appserv/PROD/LOGS/TUXLOG -m 0 -A -- -d /dev/null -n //appserver1:9101 -m 9 -M 12 -I 5 -j ANY -x 40 -S 10 -c 1000000 -w JSH

Information to gather:
  • Owner name                    : psoft
User who has started the application server
  • Location of PS_HOME   : /psoft/pt849/appserv/PROD
Path mentioned above is the appserver directory of PS_HOME
  • Domain name                  : PROD
Application Server domain name

Database server details
Navigate to PS_HOME/appserv directory using cd command
# cd /psoft/pt849/appserv/PROD

Open application server configuration file "psappsrv.cfg"
more psappsrv.cfg
; Database Signon settings
DBName= psftdb

Information to gather:
  • Database/Service name: psftdb

Enter the below command at the prompt
tnsping database/service name
tnsping psftdb

Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = psftdb)))
OK (10 msec)

Information to gather:
  • Database server host name       : dbserver
  • Port no                                    : 1521

We have backtracked our path from webserver to database server and gathered major details about webserver, application server and database server which are the main components of peoplesoft architecture.
