Hi Muthu,

Reboot the server and then take a start of SAP system.

or Clear the shared memory used by <sid>adm by using the command ipcrm command.

Hi Muthu,

Run the below comamnd

ipcs -mS (It will list the shared memory occupied)

Checked the shared memory and delete them under sidadm.

Clean the shared memory.

ipcrm -s <shared memory segment>

Also follow the steps

i. cleanipc XX remove

2. Kill all the process running under sidadm and sap process.

Also do refer the link

Hi Muthu,

Also do paste the dev_server0 and dev_jstart log , it might may happen that your port are getting used by some other process.

use cleanipc XX remove (XX instance number)

for both CI and SCS.

Also, use ipcs to find ID and clean with ipcrm.
