downgrade nw 720 to old sapccmsr agent: possible? how?

[Former Member]

SAP really missed the boat on this one...

In NW 7.0x one ran ccms agent (sapccm$$) which talked RFC and had no trouble with saprouter.

Configuration was done at the remote site and was a snap.

As of NW 7.10 the ccms agent has been replaced with sapstartsrv which is configured from CEN.

CEN talks to remote msgserver at http port 81$$ who redirects CEN to http port 5$$13 at remote host.

The configuration and connection has reversed direction and uses http protocol. Saprouter be da#$ed!

I haven't got a single java AS that isn't separated from CEN by firewall and saprouter.

I am starting to accumulate SAP NW CE 7.20 and SAP NW PI 7.11 systems I can't hook up to CEN.

We're also moving into the cloud ... that doesn't help. More saprouters...

I want to break sapstartsrv and fall back to sapccmsr! (break because sapstartsrv seems to have a memory leak...)

Is this possible? Fall back to old ccms agent at the NW 7.20 level? How?

Hi Ken,

I don't think you will be able to do the downgrade you are talking about. But here are a couple ideas:

- in addition to the saprouter, you could put a web dispatcher at your network border and configure it to forward HTTP requests to the required destinations (e.g. msg server HTTP port, sapstartsrv port 5xx13 etc). The web dispatcher version 7.20 supports multiple back-end systems and non-SAP systems as described here: http://help.sap.com/saphelp_nw70ehp2/helpdata/en/b0/ebfa88e9164d26bdf1d21a7ef6fc25/frameset.htm. It would be a pain to maintain the webdisp configuration every time you wanted to add a new monitored system though.

- if the boundary between your CEN's network and the satellite system's network is secure (not internet, but internal like a Hosting company's MPLS/VPN connections to customer networks) you could use a forward proxy server which would be a lot simpler -- if the CEN supports this (haven't checked but most SAP functions that rely on the web are smart enough to support a proxy server)

- take the plunge and join the ramp-up to SolMan 7.1. The new monitoring concept skips the CCMS agents completely and relies on the SMD agents. Of course the SMD agents come with their own set of problems (grin) but at least the newer versions support connectivity over a saprouter

Good luck!
