PI Upgrade Error :Unable to execute the SDT request ABAP operation extract on hostname & Could not connect to host <hostname> on port 4240.

Dear Experts,

We are doing upgrade of PI  System from NW 7.3 to NW 7.3 EHP1 SP14

with SUM Tool 1.0SP12_14.

Our system : ( AIX, DB2 , PI -  NW 7.3 )

We got stuck on ABAP Extraction phase in SUM ,

Below is the error: unable to execute the sdt request abap operation extract on hostname

and also  we got the error as could not connect to host on port 4240.''

Unable to execute the SDT request ABAP operation extract on hostname

<hostname> instance 00

Extraction of the ABAP upgrade request ABAP has failed

Error from unit observer Tool connector failed.

Connection to SAPup could not be established, see following messages.

Could not connect to host <hostname> on port 4240. Connection refused Connection refused

1.I tried to do the upgrade with fresh SUM from Market place , but I got stuck at extraction

phase .

2. we have tried to free the port 4240  and also we had taken a clean

reboot of system , still it point to the same error

3. we have used to change the port and run the below command

./STARTUP httpport=4438 guiport=4436 -srvarg=/UseCaseService/abaptoolport=4434

and we have changed the port 4240 to 4440 in sdt request.xml and sdtstatistics......xml

4. given full permissions on Upgrade DIR -- No luck.

but unfortunately no luck , still we stuck on this error

Below  attached is the snapshot of the issue on SUM and We have issue on PIP  system

Could you please help us in resolving the issue  or give us suggestions.

Hi shafeeq,

If you are running the SUM from a NFS mount point then you might face the issue.

So extract the SUM tool in /usr/sap/<SID>/ and then start the STARTUP SCRPT.

Let me know the outcome.

With Regards
