Limitations
The SSL connection between the Java SSL client (QXO webapp on Tomcat) and the SSL server (SSL-enabled QXOUI AppServer) is slower because of encryption and decryption of data on both ends. The performance could be slow with OE11.1 because Progress APIs from OE11+ use secure random numbers for the Java client to connect to the SSL-enabled AppServer. The connection takes time, especially on Virtual Machines. The workaround is to use the OS Random Number Generator to increase the Entropy to speed up the random number generation, but at the same time, it reduces security. On OE10.2B and lower versions, the performance is not an issue.To run the OS Random Number Generator for OE11 and later versions:• On Linux: Execute the /sbin/rngd -r /dev/urandom command as root.
• On HP-UX: There is no native random number generator. Install it from the HP site and configured it on HP-UX.
