Release Notes
About what System Agent release is shipped by any CA WAAE release:
When you expand the .iso image of the CA WAAE scheduler DVD, select your platform, then select the "AGT" directory, then "patches".
For example, on the CA WAAE 11.3.6 SP6 image, this "patches" directory name is "1-SP7" which in fact contains the files used to install/upgrade the System Agent to 11.3 SP7
If you repeat the same exercise with the CA WAAE 11.3.6 SP5 DVD, you'll see that it brings up the System Agent to 11.3 SP6
With the CA WAAE 11.3.5 DVD, for Linux, the "patches" directory contains 1-RO51863.
This patch is is about: LNX-CA WA AGENT R11.3 SP1 CUMULATIVE 1
