Issue while starting en.sap

[Former Member]

Dear Experts,

We are having issues while starting a SCS instance.

ms.sap is getting started easily but en.sap does not come up.

It fails with the below message

listen failed on port/service sapdp65

initialize_global: another instance of the enque server seems to be running. EXIT

Please help me on this

Output of netstat -ao is as below

tcp 2090 0 SUESY071:sapdp65 sapnodey073:coauthor ESTABLISHED off (0.00/0/0)

it is not showing any of PID associated with this port. (2090 is not a PID)

in Unix I think you can use netstat -ap to get the PID

Below is the reply for netstat -ap, however it does not shoe any PID attached to the port

tcp 2120 0 SUESY071:sapdp65 sapnodey073:coauthor ESTABLISHED -

Output at sapnodey073 is

netstat -a | grep sapdp35

tcp 0 0 sapnodey073:coauthor SUESY071:sapdp35 ESTABLISHED

Hi Juan,

Issue is solved as port was blocked by a process from a different user other than <SID>adm.

I have stop that process and restarted the SCS instance.

Thanks for all your help!!

Thanks for the reply, below is the output of netstat

netstat -a | grep sapdp65

tcp 2070 0 SUESY071:sapdp65 sapnodey073:coauthor ESTABLISHED

Does this mean, this port is in use? if yes how i can free it up or can i start en.sap on another port.

Thanks in advance!!!

I think you can use netstat -ao to get the PID of the service/program using the port.

If you are 100% sure that this is either a hanging/dead process or you are not affecting anything just kill the process and the port will be free

Seems like the port is been used?... is system number 65 unique in this box?...

check netstat -a for details on ports status...
