Anybody got experience with implementing SSL on Sybase ASE 15.7 SP100 or higher?
I'm especially interested in performance impact of using SSL (especially with openssl)
With SSL opening the connection is slightly longer, but not really an issue so far.
But how does it work on a busy ASE server?
Will it cause significant extra load on the ASE?
Does it require changing some configuration options? like increasing additional network memory?
The commands to create self signed certificate with openssl, adding the certificate with sp_ssladmin and add the SSL listener is not that well documented
Main thing I noticed on ASE 15.7 SP122 I had to run this before I could add the certificate:
exec sp_ssladmin 'setcipher', 'All'
Check with: exec sp_ssladmin lscipher
if no rows returned, SSL will not work.
Config option "enable ssl" is static, so I bounced the ASE server.
After that adding the ssltcp listener with sp_listener "start", "ssltcp:host:port" was not working.
Every time got the same error: the specified port xxx is invalid
Bouncing the ASE server solved that issue, listener started fine.
what's your experience with openssl and Sybase ASE?
