Changes to SAP Netweaver 7.3

Question

Hello,
We did an upgrade last month to SAP Netweaver 7.3 (BI double stack) and we noticed that in our services (SMICM) SMTP was not active anymore.
I checked the instance profile and saw that these services were added in the profile :
icm/server_port_1 = PORT=5$(SAPSYSTEM)00,PROT=HTTP,TIMEOUT=60,PROCTIMEOUT=600
icm/server_port_2 = PORT=5$(SAPSYSTEM)01,PROT=HTTPS,TIMEOUT=60,PROCTIMEOUT=600
icm/server_port_3 = PORT=5$(SAPSYSTEM)04,PROT=P4
icm/server_port_4 = PORT=5$(SAPSYSTEM)06,PROT=P4SEC
icm/server_port_5 = PORT=5$(SAPSYSTEM)07,PROT=IIOP
icm/server_port_6 = PORT=5$(SAPSYSTEM)03,PROT=IIOPSEC
icm/server_port_7 = PORT=5$(SAPSYSTEM)08,PROT=TELNET,HOST=localhost
I tried to add icm/server_port_8 with SMTP but when this was done the system won't start anymore.
When i put all the above lines in comment the system starts up normally and the SMTP service is active again.
But i miss 3 services : P4SEC, IIOPSEC and HTTPS.
Are these services ncessary in Netweaver 7.3 or not ?
Can anyone help me with me problem ?
Regards,
Marc.

Hi,
I think the reason of your "new" services is that you have decided to keep BW 7.3 as double stack.
As Netweaver J2EE 7.3 does not have a dispatcher process anymore it uses the ABAP stack ICM instead.
Therefore the ICM needs now to listen to the ports needed by the specific J2EE protocols (P4, IIOP, TELNET, etc).
This does not explain why you cannot add the SMTP line.
This may be one more reason why dual stack is no more recommended.
In my company we also have an upgrade project from BW 7.0 dual stack  to BW 7.3 with abap and J2EE stacks separated as 2 different SIDs. In fact we just upgrade BW abap and we reinstall from scratch BW java.
