[2013-04-02T12:12:09+05:30] [webcache] [NOTIFICATION:1] [WXE-09612] [main] [ecid: ] Oracle Web Cache 11g (11.1.1.6), Build 11.1.1.6.0 111121.2021

[2013-04-02T12:12:09+05:30] [webcache] [ERROR:1] [WXE-09707] [main] [ecid: ] Failed to start the server.

Cause:

> There is in an inconsistency at the O/S level in the IPv6 setup which makes WebCache try to listen on an IPv6 interface although IPv6 is not really configured.

> You can verify if the IPV6 enable by  "lsmod |grep ipv6", if you don't find the module, then it's not IPV6-enabled in the kernel.

Solution:

1. Stop WebCache with $MW_HOME/<instance home>/bin/opmnctl stopproc ias-component=webcache1 a

2. Backup the $MW_HOME/<instance home>/config/WebCache/webcache1/webcache.xml file.

3. Add the <IPV6 ENABLED="NO"/> tag below the </MULTIPORT> tag  as in the following example:

<MULTIPORT>
         <LISTEN IPADDR="ANY" PORT="8090" PORTTYPE="NORM"/>
         <LISTEN IPADDR="ANY" PORT="8094" PORTTYPE="NORM" SSLENABLED="SSL">
            <WALLET>/oracle/product/middleware/asinst_1/config/WebCache/webcache1/keystores/default</WALLET>
         </LISTEN>
         <LISTEN IPADDR="ANY" PORT="8091" PORTTYPE="ADMINISTRATION"/>
         <LISTEN IPADDR="ANY" PORT="8093" PORTTYPE="INVALIDATION"/>
         <LISTEN IPADDR="ANY" PORT="8092" PORTTYPE="STATISTICS"/>
      </MULTIPORT>
      <IPV6 ENABLED="NO"/>

4. Restart WebCache and verify it can be started up now.

$MW_HOME/<instance home>/bin/opmnctl startall

    Great, It helps. Thanks for sharing

    Just correct

    Muchas gracias por recordarme esto, por default esto no sucede en un OEL 5.5 pero esta vez lo hice que un OEL 5.9 y me ocurrio el mismo error

    Agrego que en algunos casos luego de agregar esa linea en el archivo les pasa que los 2 componentes webcache1 estan Down, como Root debemos configurar las mismas variables de entorno que usa oracle

    Ir a ../as_1/webcache/bin y ejecutar como root webcache_setuser.sh de esta manera
    # sh webcache_setuser.sh setroot oracle

    El archivo webcached tendria que tener los siguientes permisos
    -rwsr-x--- 1 root oinstall 7.8M Aug 23 11:57 webcached
