Changing the SSL values below take effect immediately.
Question, if a process that uses SSL is constantly running, does it need to be recycled for the changes to take effect.

Paul,
Yes, you will want to change the QSSLCLS system value. Here's what I am using now on my 7.1 systems to eliminate SSLv3 and the reduce the number of allowed Ciphers for my servers:
System value . . . . . : QSSLCSL
Description . . . . . : Secure sockets layer cipher specification list
Sequence Cipher
number Suite
0
10 *RSA_AES_256_CBC_SHA256
20 *RSA_AES_128_CBC_SHA256
30 *RSA_AES_128_CBC_SHA
40 *RSA_AES_256_CBC_SHA
50 *RSA_3DES_EDE_CBC_SHA
60 *RSA_DES_CBC_SHA
System value . . . . . : QSSLCSLCTL
Description . . . . . : Secure sockets layer cipher contro
Cipher control . . . . : *USRDFN *OPSYS, *USRDFN
System value . . . . . : QSSLPCL
Description . . . . . : Secure sockets layer protocols
Protocols
*TLSV1
*TLSV1.1
*TLSV1.2

Jim,
System values.
Do I need to change QSSLCSL?
Normally, this is managed by IBM PTFs, correct?
QSSLCSL *SEC Secure sockets layer cipher specification list
QSSLCSLCTL *SEC Secure sockets layer cipher control
QSSLPCL *SEC Secure sockets layer protocols

Rob,
I think so, but not sure.
Where do we look to see if configured?

Ok, maybe you found no usage, but that may not mean that you don't still have it configured? Is that the issue?

I was notified by our corporate security admin (via Nessus scan) that
SSLv2 and SSLv3 were still being used on the I and needed to be disabled.
20007
SSL Version 2
and 3 Protocol
Detection
Medium 10.5.2.5 TCP
21 No iSeries
I turned on the TRCINT per doc N1020594, left it run for 7 days, found no usage of SSLv2 or SSLv3, only *TLSV1.0
http://www-01.ibm.com/support/docview.wss?uid=nas8N1020594
What am I missing here?
How and where do I confirm if SSLv2 or SSLv3 is still configured?
How do I disable?
Thank You
