Web Application Performance Issue (WLS 12)

Hello guys,
I am new to weblogic and i recently downloaded weblogic server 12.1.3.0 and i created a domain and successfully deployed my web application.
My web app is Java Based (Mainly Servlets , DWR Requests ..), the problem is that it takes for ever to start and it is very slow .
I deployed it on Tomcat 7 previously and had no problem it was very quick.
I tried changing the JVM Arguments (xms , xmx and XX:MaxPermSize) but no luck with that .
Kindly can anyone help me with this issue .
Thanks in Advance.

What operating system are you using?
make sure you are trying a certificated configuration JDK and OS.
Oracle Fusion Middleware Supported System Configurations
If using unix/Linux OS based you migh be hitting low entropy issue, you can add
-Djava.security.egd=file:/dev/./urandom to JAVA_OPTIONS and retest the issue
Best Regards

  • 1 core VS multi core in a web application: performance issue

    Hi,
    I'm having trouble with a web application in a multi cpu server (w2ksp4, iis+wl9.2)
    I have prepared a set of JMeter stress tests, and the application is only capable to finish 5 transactions in a multi cpu (2 cpus with 2 cores each) but if I bind the JVM of the weblogic process to only 1 core, then the application can handle more than 60 transactions without errors.
    I'm in production side; developers tell me "hardware problem" but it seems more likely a poorly designed application (as per my previous experience with them)
    The syntoms are lot of null pointers exceptions and threads stuck when in multi core scenario.
    Althought I have not put lot of details, any of you have ever seen something similar?
    If anybody needs further information please feel free to ask
    Thanks,
    Antonio

  • Bex Web Application Designer issue: portal communication error

    hi experts,
    I am working with Bex Web Application Designer in BI7. we are using SP9. When i try to use the Web template its giving below error.
    The Requested operation could not be performed due to portal communication error.
    its message class is RSBOPLAP and message number is 018 and description is Java System error: An unknown error occured During portal communication.
    when i double click the below error details given.
    Diagnosis
    An error occurred in the BI components on the SAP J2EE Engine.
    System Response
    Procedure
    Contact your system administrator to have the error analyzed in detail.
    Procedure for System Administration
    Start the Visual Administrator, log on to the SAP J2EE Engine and choose "<J2EE_SID>" ->"Server" -> "Services" -> "Log Viewer".
    The file "defaultTrace.trc" includes detailed information about the error that occurred. In Windows, you can find this file in the Log Viewer under "Cluster <computer name>" -> "Server <server number>" -> "<drive>:\usr\sap\<SID>\JC<INSTANCE>\j2ee\cluster\server<NUMBER>\log". ". In Unix, the file is located under "/usr/sap/<SID>/JC<INSTANCE>/j2ee/cluster/server<NUMBER>/log".
    If the file does not include enough detail about the error, you can increase the log level to obtain more information. To do this, choose "<J2EE_SID>" -> "Server" -> "Services" -> "Log Configurator". On the "Locations" tab page, choose "com" -> "sap" -> "ip" -> "bi" -> "webapplications". Using the selection list on the right side of the screen, you can increase the log level, whereby "DEBUG" represents the log level with the most information. You can save your settings by choosing the "Save" icon. The change to the log level is active immediately. Once you have successfully analyzed the error, you should set the log level back to its default value using the appropriate pushbutton; continuous writing to the log file negatively affects the overall performance of the system.
    please give solutions to resolve the issue.

    hi shambhu,
    thanks for the reply, yes its related to basis but they are unable to trace it out. is SP9 support Bex Report Designer and Bex WAD??

  • Socket based application - Performance Issues - Suggestions Needed

    Hi All,
    We have an application which basically has been developed using core java. Here is a high level information about the application:
    a) It opens a serversocket which allows clients to connect to it.
    b) For every new client connection, a separate thread is created and this thread deals with requests from clients, processing the data and replying back to clients.
    c) Each socket is polled continuously and sockettimeout is 2 seconds. If there is a timeout, we handle the situation and socket is again read. So basically sockets is read every 2 seconds. If number of timeouts reaches a configurable value, we close the connection and thread is dropped as well.
    d) In production, three instances of this application are running with the help of a cisco load balancer. It is there for last 5 years.
    However there has always been some minor performance isssues and we have sorted them out using different types of garbage collectors, by introducing hardware load balancers, upgrading the code for new Java versions. It is currently running on 1.4.2.
    However there has always been some performance issues and today while googling over internet I came across following on the bea website which says that core java sockets are not as efficients as native API. BEA has implemented its own APIs for weblogic. My queries are:
    a) Are there any better Java Socket/network API (for solairs, I know Java is plateform independenet but there could be lib which also using native libs) which are much more efficient than Core Java.
    b) We are getting the InputStream/OutputStream and creating objects of DataInputStream/DataOutputStream to read the data 'Byte-By-Byte'. Each byte can have different information thats why it is required. Are there any better way of getting info than what we are currently doing.
    c) As I mentioned, we are continously polling the socket for read operation with a timeout value of 2 seconds. What is the better among the following from performance point of view: (1) Frequent read operation with a lesser timeout value or (2) Less Frequent read operations with larger timeout value. (3) Any better idea??
    Please suggest few things or pointers which I could do to improve the performance of the applcations. Many thanks.
    Thanks,Akhil
    From BEA website:-
    "Although the pure-Java implementation of socket reader threads is a reliable and portable method of peer-to-peer communication, it does not provide the best performance for heavy-duty socket usage in a WebLogic Server cluster. With pure-Java socket readers, threads must actively poll all opened sockets to determine if they contain data to read. In other words, socket reader threads are always "busy" polling sockets, even if the sockets have no data to read. This unnecessary overhead can reduce performance."

    My recommendations:
    - Always use a BufferedInputStream and BufferedOutputStream around the socket streams
    - Increase the socket send and receive buffers to at least 32k if you are on a Windows platform where the default is a ridiculous 8k, which hasn't been enough for about 15 years.
    - Your 2-second timeout is far too short. Increase it to at least 10 seconds.
    - Your strategy of counting up to N short timeouts of S seconds each is completely pointless. Change it to one single timeout of N*S seconds. There is nothing to be gained by the complication you have introduced to this.

  • Application Performance Issue

    Hi !
    We have developed a web application which was moved to staging around an year ago. Now the application is facing connection failures and session time outs. We inferred that it is 'coz of the increase in the size of database resluting in larger outputs causing the timeouts..There are hundreds of users accessing the application at a given time....and lakhs of recs in each table...around 60 tables in total
    We are using weblogic server 5.1 and java,jsp,ODBC for the application development. We suggested that the connection pools size be increased and the time out value be increased as well....
    But , we r also trying to check the frontend to see if it can be optimized in a better way....
    My question is ..do u think that the usage of preparedstatement in place of statement object in jsp's and java files is going to make any difference....
    Also, can u also suggest any other methods to follow to optimize the performance....
    any suggestions are welcome..Thanks in advance

    Prepared statements make a difference if you execute the same query over and over again. It means it doesn't have to parse the sql string each time, but can just plug in different parameters.
    In your case though, I don't think it would make much of a difference. The time is being spent in running the query, not parsing it.
    I would look at your database queries - maybe add an index to the table to speed things up?
    What database are you using specifically? How are you connecting via ODBC? Using the JDBC-ODBC bridge? Maybe look at a pure JDBC driver?
    The general rule is that 90% of the time is spent in 10% of the code. Its finding the 10% you need to optimize that is the problem. Run a profiler to see what is taking the time.
    Good luck,

  • ADF-JSF: Application Performance Issue

    Hello!
    My question or set of questions will be a bit vague...I am simply not sure where to look for problem(s). So here is what I have. Application implemented with ADF-JSF (JDEV ver:10.1.3.2.0). It basically has 5 pages. Each page containes user input form, commandButton and result table. Functionally, each page is a 'search page' that returns results based on what user specified in the form. Components on each page are bound to VO that is based on EO (DB table). Tables have at least 2.5M records up to 16M. Certain indexes exist (for most common searches) to improve the performance. However, there have been performance issues found and largely they would be grouped into the following:
    1. User is on page A, performs the search, goes to page B (via link) and performs other search, then goes back to A and similar search takes much longer to return results. Seems to me that this moght be related to memory. Maybe results of the previous search are cashed and it takes new search to retreive results longer as the VO cashe needs to be cleared first. Does that make sense?
    2. User is on page A and then goes to B. Leaves browser for 10-20 minutes and tries to go back to A. It takes up to a minute before page reloads with the previously displayed results. I am thinking this has to be related to page lifecycle where AM tries to re-execute bindings ( I do not think it is passivation issue though). What is the best practice to control the lifecycle?
    Any pointer on where to look for the solution is very welcome.
    Rade

    Carl,
    To use Tom Kyte's analogy, you are firing a gun into a room full of people hoping to hit the bad guy. You haven't seemed to have gotten any information about where the performance issues lie. It could be in the DB, network, ADF Business Components, JSF layer, other stuff monopolizing resources, etc, etc. I have ADF BC apps developed in 10.1.3.3 that run quite well.
    So, I would recommend you spend some time investigating where the performance problems lie. Try turning on logging output, check machine utilization - use your investigative techniques to find the bad guy so you can then work on fixing him.

  • Excluding Members from EPMA application - performance issues?

    We are building a new application using dimensions from our Shared Library and I had a question about excluding some members.
    For one dimension, I was able to use the "Add to App View" functionality, which was able to bring in only the one tree of members I wanted, without having to exclude anything, which seems to be the best way of doing this.
    For another dimension, I need to pick and choose members from within the hierarchy, so I will need to add almost all parents, and then go through and exclude some members. Will this cause any performance issues having excluded members? Will the excluded members get deployed to planning or do they just sit in EPMA?
    Any help would be appreciated.

    Hi,
    Excluded members are not deployed to Planning, therefore would not impact performance negatively.
    Cheers,

    There is some performance issues
    Example:
    Old serve     : 1 hrs (time taken)
    New server  : 2 hrs (time taken)
    Could you please tell me how to increase the webi report performance in new server?

    We are having Backend as SAP BW.
    Dashboard and Webi reports are created with Backend SAP BW.
    i.e thru Universe on top of Bex query and then webi report and then dashboard thru live office.
    My point is that when we have created webi reprts with date range as parameter(sometimes as mandatory variable which comes as prompt in webi) or sometimes taking L 01 Calender date from Bex and creating a prompt in webi,  we are facing that reports are taking lot of time to open. 5 minutes 10 minutes and sometimes 22 minutes  to open.
    This type of problem never ocurred when Backened was Oracle.
    Also when drilling in webi report,it takes lot of time .
    So can you suggest any solution?

    Hi Gaurav,
    We logged this issue with support already, it is acknowledged.
    What happens is that whenever you use an infoobject in the condition
    (so pull in the object into condition and build a condition there,
    or use that object in a filter object in the universe and then use the filter)
    this will result in that object being added to the result set.
    Since the query will retrieve a lot of different calendar days for the period you selected,
    the resultset will be VERY big and performance virtually non-existent.
    The workaround we used is to use a BEX variable for all date based selections.
    One optional range variable makes it possible to build various types of selections
    (less (with a very early startdate), greater (with a very far in the future enddate) and between).
    Because the range selection is now handled by BEX, the calendar day will not be part of the selection...
    Good luck!

  • Accessing BPEL processes via a proxy web service performance issues

    Hello,
    I have more BPEL processes implemented, each such a process implementing business functionality in a certain domain (generally, a domain has more business processes).
    The request was to provide a single web service for each domain. It means that all the business methods (processes) in the same domain should be accessed through the same web service. This request doesn't make possible to expose the BPEL processes themselves as web services that could be directly consumed by different clients of the application.
    The alternative will be to implement the "domain" web services through a Java class, for instance. With this approach, the Java based domain web services will expose the needed business methods to the clients. And the Java class will get the request input parameters and will call the corresponding BPEL process via SOAP. This scenario would be fine, but... this approach would imply a supplementary marshalling/unmarshalling process at the domain web service level. The data returned by the BPEL processes could be very large and in such a situation the Java based domain web service will introduce an important performance drawback.
    Is there any other solution to this case that will allow the using of a "proxy" domain web services that will not introduce any important drawback via marshalling/unmarshalling?
    Many thanks in advance!

    Hello,
    First, thank you Sandor for your answer.
    I understand that it is possible to create a BPEL process that exposes multiple operations/messages. This would be exactly what I need: a single process (web service) that will expose many operations. Could anyone, please, point me to such an example?
    So far I thought that there is possible to have only one operation exposed with a BPEL process, what is delimited between the receive/reply blocks (in the synchronous case).

  • BPS Web Application performance

    Hi
    We are facing serious performance problems when opening a BPS planning web layout. This has been working fine until we compressed the planning cube accesed trough the layout. When monitoring the dialog processes it seems like the process i hanging without doing anything. There is onlye about 25k records in the cube an only about 10 characteristics so in general it is a very little transactional cube.
    Queries against the transactional cube is responding normal.
    We are using Oracle 10.2.0.2.0 and BI 7.0 SP13
    Has anybody experienced this? and do you know the solution.
    Chris

    Not sure if this helps
