SOA Cluster Installation - Issues & Resolutions

Some issues that we might face during cluster installation:

Issue#1:

XML Parsing Error: no element found on esb console

Resolution#1:

The cause of the error was cluster_name collision for esb-dt and esb-rt.

vi $ORACLE_HOME/j2ee/oc4j_soa/applications/esb-rt/META-INF/orion-application.xml
vi $ORACLE_HOME/j2ee/oc4j_soa/application-deployments/esb-rt/orion-application.xml

Change “cluster_name” value to “ESBCluster” from "esb". Update your esb systems with this name on esb console i.e. update Cluster Name of each system with "ESBCluster".

Issue#2:

You see message “You have more than one instance of the Application Server Control application running in this cluster. This is not a recommended configuration and could lead to unexpected problems. Please stop the additional instances of Application Server Control or disable routing to these instances.” on the enterprise manager console.

Resolution#2:

Execute below command on all the non primary nodes.

opmnctl stopproc process-type=admin application=ascontrol

Issue#3:

When replacing the existing OPatch with a new patch then on running command opatch –version below error might come:
-bash: $ORACLE_HOME/OPatch/opatch: Permission denied

Resolution#3:

cd $ORACLE_HOME

chmod -R 755 OPatch

Issue#4:

java.net.SocketTimeoutException: Read timed out or java.net.SocketTimeoutException: connection reset when trying to initiate a bpel process on the bpel console.

Resolution#4:

Modify httpd.conf available at $ORACLE_HOME/Apache/Apache/conf on all the nodes.

Set KeepAlive as ‘Off’. Restart HTTP Server using command

opmnctl startproc process-type=HTTP_Server

I also recommend to cross check your load balancer setting. Sometime incorrect setting also causes this issue.

Issue#5:

An unhandled exception has been thrown in the ESB system. The exception reported is: "java.lang.Exception: Failed to create "ejb/collaxa/system/DeliveryBean" bean; exception reported is: "javax.naming.NameNotFoundException: ejb/collaxa/system/DeliveryBean not found

Resolution#5:

Modified ant-orabpel.properties file available @ $ORACLE_HOME/bpel/utilities.

Cluster=true

oc4jinstancename = SOA_GROUP

local.oc4jinstancename = oc4j_soa

Please make sure there is no space after true,SOA_GROUP and oc4j_soa.

Issue#6:

During installation of Oracle Service Registry, the installation fails with “null

Installation failed. If accessible, see "/oracle/registry_10_1_3/log/install.log".

To correct installation parameters and resume installation click Recover.” error.

Resolution#6:

One cause of this error is incorrect java version.

[oracle@HOSTNAME ~]$ java -version

java version "1.4.2"

gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-44)

update the JAVA_HOME to point to the soa suite java

export JAVA_HOME=$ORACLE_HOME/jdk

Issue#7:

During installation of DB, swap space requirements availability check the expected result ie swap memory is less than the actual result.

Resolution#7:

You can resolve this issue by creating a swap file. If installer is expecting 7832 the swap should have 7832*1024 = 8019968

1. Login as root

2. dd if=/dev/zero of=/swapfile bs=1024 count=8019968

8019968+0 records in

8019968+0 records out

8212447232 bytes (8.2 GB) copied, 82.5765 seconds, 99.5 MB/s

3. mkswap /swapfile

Setting up swapspace version 1, size = 8212443 kB

4. swapon /swapfile

5. Edit /etc/fstab

/swapfile swap swap defaults 0 0

6. Verify by cat /proc/swaps

7. Exit from root
