Cause:
SOA is very strict in namespaces.
- Open the wsdl in JDEV to find cause of the issues.
- Check the import schema elements for discrepencies.
- Check if Schema being imported has same targetNamespace as the WSDL's targetNameSpace. Then import the same targetNamespace.

Swap Space in Linux
How to check the swap file in linux:
root> swapon -s
Disk Usage :
root> df -m
Memory usage:
root> free -m
To create 1GB swap space
root> sudo dd if=/dev/zero of=/swapfile bs=1M count=1024
root> sudo mkswap /swapfile
root> sudo swapon /swapfile
root> /swapfile swap swap defaults 0 0
root> /swapfile swap swap defaults 0 0
To Add additional Swap space:
root> dd if=/dev/zero of=/extraswap bs=1M count=6144
root> mkswap /extraswap
root> swapon /extraswap
root> vi /etc/fstab
/extraswap none swap sw 0 0
Add the above Line.
Sort Disk usage :
Sort Disk usage :
du -H --max-depth=1 /home/user
Linux Setup for SOA install on AWS -EC2
Create a M3-Large instance on AWS -EC2:
Create m3 large instance for SOA installation on AWS -EC2.
1. Choose Static Elastic IP. So that you do not loose IP when server is restarted.
2. Save the KeyPair on local Machine. Use PuttyGen to create the PPK file.
3. Use Putty to login to the terminal using the PPK.
a. Hostname: Public DNS name from AWS console.
b. Port : 22 for ssh.
c. Putty-> connection -> ssh -> Auth -> Browse for PPK file.
4. Default username used to login to AWS Instance is 'ec2-user'.
root> vi /etc/sysconfig/network
Change Hostname to Fully Qualified name.
HOSTNAME=obprodb.objectprosolutions.com
Change HOSTName on AWS EC2 Linux:
root> vi /etc/sysconfig/network
Change Hostname to Fully Qualified name.
HOSTNAME=obprodb.objectprosolutions.com
Direct your custom hostname to AWS Public IP:
Create the A Record in your DNS control pointing to AWS PUBLIC IP.
Create User:
From Root user:
ec2-user> sudo useradd oracle
ec2-user> sudo su - oracle
oracle> mkdir .ssh
oracle> chmod 700 .ssh
oracle> touch .ssh/authorized_keys
oracle> chmod 600 .ssh/authorized_keys
oracle> vi .ssh/authrized_keys
Paste the public key here.
P.S: PuttyGEN is used to dispaly the public key
Now login to terminal using the new user 'oracle'.
To Delete a user:
userdel -r oracle
To allow Remote access to User:
su - oracle
mkdir .ssh
chmod 700 .ssh
touch .ssh/authorized_keys
chmod 600 .ssh/authorized_keys
Run YUM Update:
root> yum update

WSM-00138: The path to the certificate is invalid
Scenario:
Oracle SOA calling secured service on Vordel Gateway. OWSM policy used is 'oracle/wsm_username_tokoen_with_messsageprotection_client'. Using this policy request message signed with SOA platform's certifacte along with UserNameToken.OWSM policy expects the response message also be signed. So we have configured the gateway the sign the response message with Root CA.
We have imported Root CA to SOA's Keystore as trust.
Issue:
The path to the certificate is invalid. [[
Validation failed for the
certificate "Subject DN:- CN=test.oprosoa.oprohome.com, OU=Information
Technology, O="ObjectPro LLC.", L=Atlanta, ST=Georgia, C=US, Serial Number:-
132780370344752896279323, Issuer DN:- CN=OPRO Enterprise Certification
Authority 01, DC=ObjectPro LLC, DC=com"
Certificates in cert path
used for validation are:-
"Subject DN:-
CN=test.oprosoa.oprohome.com, OU=Information Technology, O="ObjectPro LLC.", L=Atlanta, ST=Georgia, C=US, Issuer DN:- CN=OPRO Enterprise
Certification Authority 01, DC=ObjectPro LLC, DC=com"
]]
Solution:
According to Below Oracle Notes. We need to import if any intermediate chain of certificates as well, in order to successfully read the response.
We have imported the dependent ENT CA certificate and issue is resolved
Cause: The intermediate and root certificates of the certificate were not present in the keystore during verification.
Action: Make sure that the entire certificate chain is available in the keystore for verification.
Level: 1
Type: ERROR
Impact: Security
