Peoplesoft database connectivity part 3/3 : Apps/Batch/Pia

After DataMover and AppDesigner, last part of the Peoplesoft database connectivity, this one devided in 4 parts : the application server, the process scheduler, the PIA and finally the front end user connections.
Once again, all these tests will require a level trace settings, but only on server side. The files generated will be only on server, under $PS_CFG_HOME/appserv/domain_name/LOGS and $PS_CFG_HOME/appserv/prcs/domain_name/LOGS.

Note : all the tests below have been done from a W2k8 64bit workstation, on Peopletools 8.50.02 , Peoplesoft OVM database server (Peopletools 8.50.02/HCM9.1), Peoplesoft App/Batch server (Peopletools 8.50.02) and Peoplesoft PIA server (Peopletools 8.50.02).

1. The Application server connection
To determine how the connection is working, we'll set the trace file in the configuration file psappsrv.cfg as following :
;=========================================================================
; Server Trace settings
;=========================================================================

;-------------------------------------------------------------------------
; SQL Tracing Bitfield
...
;TraceSql=0
TraceSql=63
TraceSqlMask=12319
...
;TracePC=0
TracePC=2124
TracePCMask=4095
Then simply start the AppServer :
----------------------------------------------
Quick-configure menu -- domain: APPDOM
----------------------------------------------

TDE Encryption Algorithm: ''
1. connect to the database with connectid (people)
2. check database name in PSDBOWNER
3. check if the user choose to manage the appserver (PS) is an application user in PSOPRDEFN and get the SYMBOLICID
4. from SYMBOLICID, it takes the ACCESSID and password
5. reconnect to the db with ACCESSID user (SYSADM)
=> Starting the application server does nothing but a 2tier connection

Again, there are hundreds of queries fired when starting the application server, we'll keep only the following :

=> Once again, update and insert for auditing purposes, and then an interesting query, the last one to check if the user PS configured to managed the AppServer is authorized to do so. Unfortunately, nowhere in the log file we can see which role is required.

2. The Process Scheduler connection
To determine how the connection is working, we'll set the trace file in the configuration file psprcs.cfg as following :
[Trace]
;=========================================================================
; Trace settings
;=========================================================================
; SQL Tracing Bitfield
...
;TraceSQL=0
TraceSQL=63

;-------------------------------------------------------------------------
; PeopleCode Tracing Bitfield
...
;TracePC=0
TracePC=2124
Then startup the process scheduler :

No big differences between Apps and Batch server, except (of course) in the statements executed.

3. The PIA connection
To determine how the connection is working, we'll set the trace file in the configuration file psappsrv.cfg as defined in part 1 above. The PIA connects to the Application server through the JSL port defined in configuration.properties (for the PIA) and psappsrv.cg for the Application server. This is the only one link between them.
Just starting up the PIA (startPIA.sh for Weblogic) create a file under the log directory of application server : PTWEBSERVER_psovmpia.tracesql
Note : PTWEBSERVER is configured in configuration.properties to manage the webserver, psovmpia is the name of the server hosting the webserver.
And here a first remark : the name appears in clear. Ok, then what's wrong ?
The thing is the user who manage the webserver has been encrypted in the configuration.properties file :
...
## sd="Web User Id", ld="The User Id that the Portal uses to access the web profile"
WebUserId={V1.1}JP9ukEkTssmYrzsK1yvXFg==
## sd="Web Password", dt="e", ld="The User Password that the Portal uses to access the web profile", tip="The password is automatically encrypted on the server side"
WebPassword={V1.1}JP9ukEkTssmYrzsK1yvXFg==
...
And seeing this file and the log file name, we could easily determine what is the password (in that peculiar case they are same).
Going through the log file itself, it is showing the Tuxedo session connection :

So, the PIA is connecting in 3tier mode to the application server, and again, the log file does not help to determine which roles are needed for PTWEBSERVER, but helps a lot to see all the tables read and modified during the PIA startup.

4. The front end connection
The front end user has no idea about the the PIA, application server and even less about database user to be used. From the given url, he needs only an application user. But behind this "simple" action of login, hundreds of queries are executed against the database.
Here below the first lines of the file generated when a user enter to the login page and press enter (format mask of the file is _.tracesql).

So, it is starting exactly like the PIA connection, but immediately check the user's roles.
It is also checking of the Webbrowser language (here ENG) has been installed onto the database :

Bind-1 type=2 length=3 value=ENG

Finally, it takes from the database the portal name for further page construction :

...
Here we can see a big difference, so far, no Peoplecode have been seen in the trace file, the real business is starting right now, with menus and pages building.

The main conclusion of this part 3 is App and Batch are connecting in 2tier mode against the database, the PIA in 3tier mode and an other layer has been added for front end user in 4tier mode, the presentation layer.

Of course, this "series" was not to intend to answer to every single question (I did not show the entire trace file, and a lot of part are still hidden and not showing in trace file), but hopefully it helped to understand the key point of the Peolesoft security and the main differences between all the possible connection to a Peoplesoft database.

Enjoy,

Nicolas.

Hi,

Stumbled upon your blog about the peoplesoft connects. Interesting stuff.
But there is one thing youi never mention an which I (DB tuning expert) find very interesting and strange as well.
When logging on there is a query:
SELECT COUNT (DISTINCT CLASSID)
FROM PSROLEUSER A, PSROLECLASS B, PSROLEDEFN C
WHERE A.ROLEUSER = :1
AND A.ROLENAME = B.ROLENAME
AND B.ROLENAME = C.ROLENAME
AND A.ROLENAME = C.ROLENAME
AND C.ROLESTATUS = 'A'

Strange enough after this the same query is used again and now without the count. This is really weird since it is relatively expensive query in the system I am working on. In my system the query does 96 logical IO's. times 2 makes 192 logical reads. This does not seem very high, but the system I am tuning has a hugh amount of logon's.
My question, for which I have not found an answer, is WHY is it doing it twice. I do not see any valid reason for this.

Erik,
That's indeed weird, I have no explanation neither, one pass would be enough, unfortunately this is how it is coded. Probably it is a a legacy of older version...
I remember older Peopletools I worked on with a lot of login time issues (<=8.48), that has greatly been improved since then, but we have still that kind of stuff.
Just few thoughts : try to keep the lowest as possible the number of roles... You could also investigate a code change on the login to query a MView (containing all required columns - CLASSID and ROLEUSER - and refreshing on change of the underlying tables), but of course, it moves you out of support.
Good luck,

Nicolas.

Hi could you tell mewhere can I find the Query that checks the user roles at the login, some WEBLIB or FUNCLIB. Thanks a lot
