SPAM and JSPM vs. SUM for NW 7.0 support stacks
Any feedback regarding recommendation on whether to use SPAM (Abap) and JSPM (standalone java stack) vs. SUM when applying support stacks would be appreciated.
The current system being looked at is NetWeaver 7.0, both standalone ABAP and Java support stacks. Note this is sps only, not an upgrade or EHP.
SAP Tech Ed 2012 had a session specifically focusing on this topic, "ALM215 Software Update Manager – The Tool for System Maintenance", with description "Special focus is given to the question of whether to use SPAM or SUM for applying SPs." Any insight from that session would be great!
In looking at SUM for sps only, there's a debate as to whether the additional complexity layer of the tool warrants the benefits.
For example, for Abap, is the preprocessing phase (building the shadow instance) really beneficial when in the case of this particular system downtime is not really a concern.
I have seen the OSS notes stating SUM being supported for NW 7.0 and onward, that's not the question here.
Thanks for any recommendation or feedback.
