    Hi,

    I need someone  to throw light on the issue which we are facing.

    We have an WAS ND 7.0 environment with hybrid clustering of application server (a combination of horizontal & vertical app servers). The Servers run on Solaris Sparc 64 bit OS. We have 3 applications deployed over 3 set of hybrid clusters.
    Example:
    Lets assume 3 applications - AP1 , AP2 , AP3
    3 Physical nodes - N1, N2, N3
    Each Node has 2 Application Servers for each application -
    in N1 -> N1ASa, N1ASaa, N1ASb, N1ASbb, N1ASc, N1AScc
    in N2 -> N2ASa, N2ASaa, N2ASb, N2ASbb, N2ASc, N2AScc
    in N3 -> N3ASa, N3ASaa, N3ASb, N3ASbb, N3ASc, N3AScc

    Cluster - C1, C2, C3
    C1 cluster -> N1ASa, N1ASaa, N2ASa, N2ASaa, N3ASa, N3ASaa
    C2 cluster -> N1ASb, N1ASbb, N2ASb, N2ASbb, N3ASb, N3ASbb
    C3 cluster -> N1ASc, N1AScc, N2ASc, N2AScc, N3ASc, N3AScc

    AP1 -> installed in C1
    Ap2 -> installed in C2
    Ap3 -> installed in C3

    All the application servers are having same configuration, same connection time out value, almost same settings except the path

    Request flow : Request -> Load Balancer -> Web Server -> App Server

    All the Applications running (AP1, Ap2, Ap3) are having just a simple jsp page(home page) initially and then connecting to db, which(jsp home page) can be called from a link defined in an html file placed in web server.

    When the request comes to webserver for AP1 home page, the request gets routed to application server and i get the home page.

    And, When the request comes to webserver for AP2 home page, the request gets routed to application server and i get the home page.

    Now, When the request comes to webserver for AP3 home page, the request gets routed to application server and i dont get the home page or get the home page after a long time.

    When checked in System out logs of the Application Server (N1ASc, N1AScc, N2ASc, N2AScc, N3ASc, N3AScc), i get the  error in following order.

    After 15 to 20 mins, i started to get
    1. java.io.IOException: Connection reset by peer

    After some time i started to get a new error along with the existing one
    java.io.IOException: Connection close: Read failed.  Possible end of stream encountered.

    After some time, i started to get a new error
    FreePool      E   J2CA0045E: Connection not available while invoking method createOrWaitForConnection for resource OracleDS



    Request you to please throw some light on this issue

    Thanks & Regards
