Hello Jun,

Could you please check if the schema user account i.e. SAP<SCHEMA-ID>DB is locked? If it is locked then unlock it.

Also please attach dev_disp, dev_server0 and dev_jcontrol log files.

Hi,

If you are using oracle , make sure oracle client also upgraded along with kernel and DB.

Check the SCSxx instance. It must be running, otherwise the J2EE server cannot be started.

See the SCSxx/work/dev_ms file, it should contain a line that hostname is sapmk0ci

and it is listening on port number 3901.

SCS01 is not starting.

I see this in dev_ms file

Hello Juan

To find if Message Server is running or not, please check status Green in output of command:

sapcontrol -nr <SCS_Instance_ID> -function GetProcessList

For exception "[Thr 01] *** ERROR => Can't attach to message server (sapmk0ci/3901) [rc = -100]-"

1. Please check if the mshost=sapmk0ci and msport=3901 are correct and message server is actually reachable on this location.

2. In dev_ms file at location \usr\sap\<SID>\SCSXX\work you will see a statement like

[Thr  1] *** I listen to internal port XXXX (XXXX) ***

This is the correct message server port. All instances should connect to this port.

3. Please check paramters of /usr/sap/<SID>/<instanceID>/j2ee/cluster/instance.properties file

instance.ms.host=XXXXXX

instance.ms.port=XXXXXX

These should contain the correct values. If values are wrong you need to assgin correct values via configtool for all dispatcher and server nodes.

4. Please make sure that the following profile parameters exist in the instance profile in question. The instance profile can be found on the central file system share (sapmnt) in the SYS/profile directory. If they do not exist, add them.

  j2ee/scs/host = <hostname of your SCS instance>

  j2ee/scs/system = <instance number of your SCS instance>

5. Please check if all parameters exist as per following sap note:

741289 Profile parameters of the J2EE Engine are lost

6. Please check if following parameters exist in default profile file

j2ee/scs/host = <hostname of your SCS instance>

j2ee/scs/system = <instance number of your SCS instance>

j2ee/ms/port = <message server port>

If not, add them. When adjusting the DEFAULT profile please use

RZ10 transaction in R/3. If you edit the file directly the parameters

will be lost the next time the profile is modified with RZ10.

Hi Jun,

I also faced the same issue many times.

I hope by following the below steps will help u to solve this :

1.Check data base connectivity.

2.If it is failing and Restart ONLY DB and try to connect to config tool.

3.If the connection is fine then try to start JAVA.

Hope fully it will work.

Hi Jun,

         If possible better go for whole OS reboot so that services gets started cleanly.

Hi,

First of all please clean the memory(sapcontrol, cleanipc).

Then check, is there any service listening on port 3901.

You can check it with the command lsof -i:3901 on Unix.

Hi,

  Please maintain the correct hostname entry in your host file and try again.

If still you are facing the issue, please attach dev_server0, dev_disp , dev_ms for more analysis

Thanks and Regards,

Vimal

Hi Jun,

Could you check what this IP address is for  122.22.22.22.

If it is not of your server then hash this entry in /etc/hosts file and then check the system startup.
