Hi all j2ee guru
As l went through the a few manuals of iplanet 6.5. l have a few questions in mind. It is highly appreciated somebody can share with me your insight into following questions
1) In some samples come along with iplanet 6.5, in their ias-web.xml and web.xml, the web app are set as "distributable". Also, all servlets are set "sticky". My question is why the JSP don't need to be set as "sticky". If l have a web site made up of serveral ten of thousand of JSP pages, it will be a big trouble to explicitly set each page as "sticky" ??
2) Technically, are there any difference in setting the web app as "distributable" and setting servlet / jsp explicitly as "sticky" ?
3) Let's say, if the sample include a stateful session bean, do l have to set that stateful session bean to "sticky". If so,
does it mean the invocation from servlet to stateful session bean and from stateful session to CMP/BMP will take place in same JVM process.
4.1) how can l config the iplanet to make the invocation from session bean to entity bean take place in same VM
4.2) how can l config the iplanet to make the invocation from servlet to EJB including session bean and entity bean take place in same VM
4.3) how can l config the iplanet to direct the requests from same session to same JVM including HTTP session / stateful session bean.
5) Is there any latency as session is synchronized by "dsync" process. If the application is set as "distributable" (support load-balancing), but the servlet is NOT set as sticky. Will it cause any trouble due to latency of synchronization of session among iplanet servers
6) l find that l can't clear up all concept of iplanet merely studying its manual. Are there any good material / website for iplanet. Please provide them to me
thanks a lot
