    Oracle Web Cache
    Monday, December 18, 2006
    Register for R12 upgrade
    What is Oracle Web Cache ?
    Oracle web cache is component of 10g Application Server which is installed by default with Portal & Wireless or BI & Forms type Installation. You can also install standalone webcache for J2ee & webcache applications or to configure webcache with Oracle Applications 11i.

    Why I need Web Cache ?
    As name suggest web cache act as Cache for Web Servers including Oracle Application Server 9i, 10g to cache frequently used static & dynamic pages. Web Cache is used for increasing response time of your site by caching frequently used partial / full page , images, pdf. Web cache can also act as Software Load balancer or Reverse Proxy Server or Front end to your Applications to Hide server name.

    Is Web Cache configurable & Certified with Apps 11i ?
    Yes, Web cache can be configured with Apps 11i as reverse proxy server (for security) and Failover & Surge Protection (To minimize downtime) .
    *Web Cache can't be used as Load balancer for E-Business Suite as its not possible to set session stickyness in Webcache. (Thanks to Gaurav for pointing this out)

    Check Metalink Note 306653.1 Installing and Configuring Web Cache 10.1.2 and Oracle E-Business Suite 11i

    How to start / stop webcache ?
    To start/stop webcache with 10g AS, use
    opmnctl startprocstopproc ias-component=WebCache
    For standalone J2ee & Webcache Installation use
    webcachectl startstop

    How to troubleshoot Webcache Issues ?
    Webcache logs are at $ORACLE_HOME/logs event_logs & access_log , all issues errors are recorded in event_logs so check this file any issues related to Webcache .

      When u say Fusion middleware expert, does that mean u work on Oracle Fusion as well? i guess its still under development. Or it means something else??? was just curious...

    • At 12:54 AM, Blogger Atul Kumar said…

      There are two fusion projects running in parallel in Oracle, Fusion Middleware consist of oracle application server , collaboration suite , IM , soa suite , data hubs (anything apart from database) .

      What you are talking about which is still in development, is Fusion Applications (ERP)

      Hi Atul
      I don't Web Cache can be used as a software load balanceer with E-biz as Oracle doesn't support any kind of S/f load balancing. It will act as a s/f load balancer but not excatly load balancer. Refer Section 7 of NOTE.306653.1 "Configuring Oracle Web Cache solely as a software load balancer by specifying the parameter "LOADBALANCE ON="YES"" in the web cache configuration file "internal.xml" is not supported for Oracle E-Business Suite 11i and also this setting is not intended for Oracle E-Business Suite 11i. "

      Hi Guarav, Yes you are right Webcache can't be used for Loads balancing with Apps / E-Business Suite as its not possible to maintain session stickyness in Webcache which is required for Apps Load Balancer. I have updated it accordingly.
