Hi Erman

We have a load balancer infront of our EBS 12.1.3 and ssl certificates are also kept in load balancer. As per industry changes, our network administrator has updated the ssl certificates with SHA-2. Now, after the changes, the outbound notification mails were not going out. The errors were :
======
HTML content -> oracle.apps.fnd.wf.common.HTTPClientException: Unable to invoke method HTTPClient.HTTPConnection.Get caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
===

So we had to revert back the certificates to again SHA-1. So my question to you is, if the certificate changes are done in Load balancer, do we need to again import the root and intermediate certificates to our Apache server using wallet manager?
