Solman login

[Former Member]

Hello

I have just installed Solution manager 7.1 in oracle linux 7 with oracleDB 12.1. But know I cant login to solman. The sap system starts without any error:

lsnrctl start

startsap

But Saplogon cant connect to server. As I understand, saplogon connects to 3200 port. I check in server, no program listen to this port, while in other sap systems this port is listened by this process: dw.sap<SID>_DVE.

How can I find the source the problem?

Thank you

Hi Aram,

Just check whether your able to see the dw_ & ms_ process on os level.

also run the dpmon pf=<instance profile> to check the work process and are running correctly.

IF there is no work process running then do check the logs under /usr/sap/SID/DV*/work for dev_w0 and dev_ms log file for more on the error.

Also based on your instance number the port for ms will change and do check the 32<Instance number port> for listening.

And do verify your sap gui entries are correct to connect using SPAGUI.

And do maintain the sapms<SID> entries in your C:\Windows\system32\drivers\service directory

Let us know if you need any further help.

Regards,

Ram

Hello ramkrishna

Thank you for fast reply.

Just check whether your able to see the dw_ & ms_ process on os level.

There are two ms processes

ms.sapSM2_SCS02 pf=/usr/sap/SM2/SYS/profile/SM2_SCS02_test5

ms.sapSM2_ASCS01 pf=/usr/sap/SM2/SYS/profile/SM2_ASCS01_test5

and no one dw process.

IF there is no work process running then do check the logs under /usr/sap/SID/DV*/work for dev_w0 and dev_ms log file for more on the error.

There is no dev_ms file. The dev_w0 is attached to this reply. There are errors in dev_w0.

Also based on your instance number the port for ms will change and do check the 32<Instance number port> for listening.

This two ports are listened

tcp        0      0 0.0.0.0:3201            0.0.0.0:*              LISTEN      10087/en.sapSM2_ASC

tcp        0      0 0.0.0.0:3202            0.0.0.0:*              LISTEN      8573/en.sapSM2_SCS0

But I cant connect to that ports too.

When I compare with working system this line is missed

tcp        0      0 0.0.0.0:3200            0.0.0.0:*              LISTEN      23623/dw.sapSME_DVE

The sapgui entries and  services entries are correct

Best regards

Aram

Hi Aram:

As per the developer traces you provided you have *** ERROR => shmget(10040,486000000,992) (28: No space left on device)

Can you please check recommendadtion as per below:

Hi ARam,

From the dev_w0, its clear there the shared pool 40 is having no space.

I would recommend you to run the sappfpar check for  the instance profile and increased the shared pool 10 & 40.

Also do verify your kernel parameters for kernel.shmmax & kernel.shmall.

# SAP settings

kernel.sem=1250 256000 100 1024

vm.max_map_count=2000000 (see SAP Note 900929 for more information)

2002167 - Red Hat Enterprise Linux 7.x: Installation and Upgrade

2069760 - Oracle Linux 7.x SAP Installation and Upgrade

Do let us know the outcome.

Please attach output of ipcs -l command and ipcs -u (after unsuccessful start up of instance). In general you need to pay attention to kernel.shmmni and kernel.smhall parameters.

Additional share trans.log & dev_w0 log files too.

there is no trans.log file dev_w0 ahave already shared, in the third message.

In general you need to pay attention to kernel.shmmni and kernel.smhall parameters.

Where I can find the minimal or recommended values for this parameters

Now the parameters are

kernel.sem = 250        32000   100     128

kernel.shmmax = 6166132737

kernel.shmmni = 4096

kernel.shmall = 1204322

I would recommend you to run the sappfpar check for  the instance profile

The execution of sappfpar check returns this result

***ERROR: Size of shared memory pool 40 too small

================================================================

SOLUTIONS: (1) Locate shared memory segments outside of pool 40

               with parameters like: ipc/shm_psize_<key> =0

SOLUTION: Increase size of shared memory pool 40

          with parameter: ipc/shm_psize_40 =486000000

and increased the shared pool 10 & 40.

How can I change this( ipc/shm_psize_40) parameters where are they located?

This lines I find in /var/log/messages

Hi:

As indicated above you cretainly have issue with your Shared memory.

1. What kernel level are you using? Did you try updating your kernel patch?Review Note 941735
- SAP memory management system for 64-bit Linux systems

2. ipc/shm_psize_40 can be set in your instance profile parameter to a value suggested by report sappfpar. But before changing any of these values that please review above note and you may reach out to your OS Admin for help.

Hi,

*** ERROR => shmget(10040,486000000,2016) (28: No space left on device) [shmux.c

Do you check & confirm for the sufficient space on the system as well.

Regards,

[former_member182657]

Hi,

Could you share result for the command

ps -ef |grep dw  

ps -ef |grep ora 

Additional share trans.log & dev_w0 log files too.
