SOA 11g install

finally I got some time to look at 11g and the first set of challenges were to 1) set Jdev 11g and 2) to install SOA 11g on Linux

1) For Jdev we need 11.1.1.2.0 above to be able to see SOA projects, After installing JDev the SOA composite editor can be installed using -> help -> check for updates

2) Installing 11g on Linux is covered in couple of blogs one here, official site here, broadly 5 steps
a) installing DB - 11.1.0.7 (linux_11gR1_database_1013.zip and patch 6890831)
b) using RCU for SOA schemas (ofm_rcu_linux_11.1.1.2.0_disk1_1of1.zip)
c) installing weblogic 10.3.2.0 (ope111130_wls1032_linux32.bin) using bundled Sun JDK
d) installing SOA 11g (ofm_soa_generic_11.1.1.2.0_disk1_1of1.zip)
e) configuring SOA for Weblogic

Good thing is this install is much easier that 10gR3 on weblogic9.2 as all configurations are wizard based.

For DB install all the steps are covered here - make sure all steps r followed also as in patch 6890831. For additional linux packages yum can be used. While dbconsole stop/start there will be an OC4J Configuration errror, the solutions is here

For weblogic/soa set up create a Middleware directory, chowner to the oracle user created as part of db install, as OUI will not work with root user.

While starting weblogic admin server if you see following error - your weblogic version is not proper, use 10.3.2.0

Failed to initialize the application 'em' due to error java.lang.NoSuchMethodError: weblogic.application.ApplicationLifecycleEvent.getDeploymentOperation()Lweblogic/application/DeploymentOperationType;.java.lang.NoSuchMethodError: weblogic.application.ApplicationLifecycleEvent.getDeploymentOperation()Lweblogic/application/DeploymentOperationType

While starting managed serevrs if you see errors like -
BEA-000386 Server subsystem failed. Reason: java.lang.NullPointerExceptionjava.lang.NullPointerException at weblogic.management.bootstrap.BootStrap.find(BootStrap.java:473)
or
BEA-000286 Failed to invoke startup class "JPS Startup Class", java.lang.ClassNotFoundException: oracle.security.jps.wls.JpsWlsStartupClassjava.lang.ClassNotFoundException: oracle.security.jps.wls.JpsWlsStartupClass at java.lang.Class.forName0(Native Method)

start the servers as root user and best way to start the managed servers is from the admin console, and for that start nodemanager, also make sure to modify nodemanger.properties under wlserver_10.3/common/nodemanager/ with StartScriptEnabled to true.

Next is to understand the big-bang changes in 11g and appreciate the value it has to offer.
