Setting up Tomcat with SSL and client certificate authentication

1. Correctly install all OpenSSL and APR library
2. Modify conf/server.xml

<Service name="Catalina">

.....

    <Connector protocol="org.apache.coyote.http11.Http11AprProtocol" port="8443" SSLEnabled="true" connectionTimeout="20000" SSLCertificateFile="SSL.cer" SSLCertificateKeyFile="SSL.key" SSLCACertificateFile="CA.cer" SSLCertificateChainFile="CAChain.cer" maxThreads="150" scheme="https" SSLVerifyClient="require" SSLProtocol="TLSv1" SSLCARevocationFile="crl.pem" SSLVerifyDepth="2" />


.....
</Service>

remark:
All certificate file should be in PEM format
SSK.key should have no password
crl.pem should be used to block revoked certificate

Visual GC Error: Not Supported for this JVM (Remote Connection)

http://fahdshariff.blogspot.hk/2012/02/visual-gc-error-not-supported-for-this.html

An error occurred while consolidating disks: msg.disklib.CID_MISMATCH.

Today I meet this error when trying to consolidate snapshots.

Finally, I find that I could be easily solve by 1 step.

1. Click go to snapshot from the latest and try consolidate.
2. Repeat going to a earlier snapshot until you get consolidate snapshot success.
