Improve Portal Performance

[Former Member]

Hello All,

I got a opportunity to work on Portal Performance tuning activity . First time I will work in this scenario. I searched on SDN and found tons of links and forums but not any which explains about the things which need to be done .

Can someone please guide me , what are the things or settings at OS or Portal level which can be use to improve the performance of Portal.

Thanks

Hi,

check in the tons of links and forums you found for the material from SAP:

- PDFs and

- SAP Notes

that are about portal, KM, Java and OS settings.

For instance:

Hello Himani,

There are several sectors from which Portal Performance can be fine tuned -

Server side performance -

CPU Consumption

Memory (eg Java Garbage Collector, Memory Leaks)

Database Issues (SQL)

Log Responses - Only logging the critical information

Network performance (LAN, WAN)

Client side performance -

Browser optimization, Caching

Portal Runtime (PRT) for Performance

Portal Content Directory (PCD) for Performance

Page Content

Hardware Sizing & Scalability

Hi Himani,

There are different functions that are to be taken care of performance of portal likely :

A.Delta links should be used cautiously when you are after role and worksets. Especially when you are creating nested relationships between objects. For e.g. an iView can be a source as well as target. If a target is a source of another delta link, while rendering the hierarchy, rendering consumes huge chuck of time. Following image shoes typical example of such hierarchy.

B.If you have the user admin rights cehck the netweaver admisntartot(http://hostname:<port no>/nwa so that u can get all the detaisl of logs .

finally you can look into this for better peroformance :

Improve Portal Performance by Changing Log Levels

1. Open Visual Admin Tool. (usually in usr\sap\sid\DVEBMGS00\j2ee\admin)

2. Go to: active server -> Services -> LogConfigurator.

3. Click "To Advance Mode".

4. Go to the tab "Categories".

5. In each Severity field of all the logs, set the value to Error.

6. Go to the tab "Locations" and repeat the step 5.

7. Go to the active Dispatcher and repeat steps 2-6.

8. If there are more active servers, repeat the procedure for each Server

and Dispatcher node of each on of them, for the entire cluster.

9. Restart the server.

C.clear the caches in the system admisntartion -->navigation --caches and in deeply :

To improve Enterprise Portal Performance we need to do changes at Cache levelCompression EPCF service for script files

1) For changing the EPCF Service from standard to optimize

Goto System administrator -> Service Configuration -> Applications- com.sap.portal.epcfloader->Services->epcfloaderIn the properties of script set we need to change from standard to optimize

2) Compression Config Tool window, select: <instance> ?? services ?? http, and change theValue of the following properties:

Never Compressed To enable script files compression, delete the following content types from the list:

*.css, *.pdf, *.js, image, application/pdf, text/JavaScript

3) Cache level : CacheControl 604800 (seconds) Specifies the duration for keeping Responses in client cache (if the client is HTTP 1.1 Compliant).

HOPE THIS INFORMATION HELPS YOU!

Thanks&Regards
