Can not connect to SDM during SUM execution phase

[Former Member]

Hello Experts,

I am facing an issue during a patch upgrade for our Solman system using SUM.The patch upgrade i started using option "Manual stack directory" and components included for update are LM-Service/IS-AGENT/J2EE Engine/J2EE Core.

During execution phase SUM is throwing the below error

"Could not detect system components. Could not detect deployed components. Could not synchronize the table with system component versions with SDM repository. com.sap.sdm.apiimpl.remote.client.APIRemoteExceptionImpl: Server JBLDCVSDSSM03 did not accept login request as admin on port 50018. Details: ERROR: Could not establish connection to server JBLDCVSDSSM03 at port 50018: Connection refused: connect (port 50018 to address 10.51.31.36) com.sap.sdm.apiimpl.remote.client.APIRemoteExceptionImpl: Server JBLDCVSDSSM03 did not accept login request as admin on port 50018. Details: ERROR: Could not establish connection to server JBLDCVSDSSM03 at port 50018: Connection refused: connect (port 50018 to address 10.51.31.36 ".

When I checked I found that SDM is not running.I tried to start the SDM using standalone and integrated mode but no luck.

After this it is creating 2 log files "sdm_server.err" and "sdm_server.out".But both the files are of 0KB and no content is there.

Please suggest.

Hi All,

Apologies for the delayed reply.

Here is the resolutionfor the issue--

In the instance profile  of our Central Instnace we had the entry as below--

jstartup/instance_properties = $(jstartup/j2ee_properties)

This means the paramter is only requesting the startup of the J2ee engine wheras the same is
is not requesting the startup of the SDM server.

The entry should be:

jstartup/instance_properties =$(jstartup/j2ee_properties);$(jstartup/sdm_properties)

We have modified the profile as above and restarted the system again.This time SDM started without any issue and also patch update completed successfully.

Thanks all for your valueable suggestions.

Best Regards,

Debaditya

Hello,

Please check if SDM is running or not using below commad :-

sapcontrol -nr <sysnr> -function J2EEGetProcessList

if its not running please start SDM from /usr/sap/<SID>/DVEBMGS<NR>/SDM/program/StartServer.bat

even after that SDM is not starting, then please check the logs at /usr/sap/<SID>/DVEBMGS<NR>/SDM/program/logs.
