Question Re: SAP Web Application Server Port in Technology Q&A

SAP Web Application Server Port

Former Member — Wed, 02 Mar 2016 15:01:39 GMT

Dear all,

i want to connect to a Web Application Server using the HTTP port, but it is not working.

http://localhost:50100/

HTTPS is working without any problems.

https://localhost:50101/

I started hte HTTPS site and checked the system information, please see attached jpg.

The system overview tells me, that HTTP Port is null.

But how can i change it?

Thanks in advance for our help.

Kind regards,

Klaus

Hello,

Check icm/server_port_XX parameter.

You can define them in proofile parameters as described in below link.

icm/server_port_&lt;xx&gt; - Internet Communication Manager (ICM) - SAP NetWeaver - SAP Library

Default Values AS Java

icm/server_port_0 = PROT=HTTP , PORT=5$ (SAPSYSTEM) 00, TIMEOUT=60 , PROCTIMEOUT=600

icm/server_port_1 = PROT=P4 , PORT=5$ (SAPSYSTEM) 04

icm/server_port_2 = PROT=IIOP, PORT=5$(SAPSYSTEM)07

icm/server_port_3 = PROT=TELNET , PORT=5$ (SAPSYSTEM) 08, HOST=localhost

In the screenshot it shows HTTP port as "null". Check if the icm parameter for HTTP is set in the profile or not.

Dear all,

thanks for your replys.

First of all i forgot to mention, that the ABAP Stack and the JAVA Stack is running on the same Server in different instances.

I checked the profiles of the JAVA instance, there are no entries depending on

icm/server_port_xx

So i think the system will use the default values.

But i found out something strange. I checked the Ports using netstat. If i shut down the JAVA Instance and only the ABAP Instance is running i get the following entries:

netstat -ano | findstr :50100

TCP 127.0.0.1:50100 127.0.0.1:65000 ESTABLISHED 13232

TCP 127.0.0.1:65000 127.0.0.1:50100 ESTABLISHED 9084

Then i checked the Process ID 13232 and 9084

13232 disp+work.exe

9084 icman.exe

So i think icman.exe is blocking the port 50100.

How should i solve this problem?!?

I think the best way is to change the JAVA Port to another one. But how can i do that?

I added the parameter

icm/server_port_0 = PROT=HTTP , PORT=50200 (SAPSYSTEM) 00, TIMEOUT=60 , PROCTIMEOUT=600

to the JAVA Default.PFL but it did not take any effect.

What can i do?

Thanks for you help.

Kidn regards,

Klaus

Hello Klaus,

All instances have ICM to handle web requests. ABAP or JAVA.

Normally if you install a dual stack system instance numbers come with 00 (CI), 01 (ASCS) and 02 (JSCS).

If you install ABAP and JAVA stack as different systems instances come with ABAP instances are 00 (PAS) , 01 (ASCS), Java instances are 02 (PAS) ,03 (JSCS).

I see that your instance number is 01.

Is your system dual stack? Or seperate ABAP and Java systems (SIDs)?

What are your instance numbers? Can you send SAPMC screenshot?

Or can you send the output of below command running on cmd with sidadm user.

sapcontrol -nr 01 -function GetSystemInstanceList

You should also define the parameter on instance profile not in default.

Dear Yuksel AKCINAR,

Thanks for your reply. This is the status of the CMD command:

sapcontrol -nr 01 -function GetSystemInstanceList

03.03.2016 09:49:24

GetSystemInstanceList

hostname, instanceNr, httpPort, httpsPort, startPriority, features, dispstatus

XXXX, 2, 50213, 0, 1, MESSAGESERVER|ENQUE, GREEN

XXXX, 1, 50113, 0, 3, J2EE|IGS, GREEN

Here is a screenshot from the SAP MMC

JM3 is JAVA, PM1 is ABAP.

I hope it helps.

Kind regards,

Klaus

yakcinar — Thu, 03 Mar 2016 09:10:36 GMT

Hello Klaus,

So, if you define this parameter in instance profile of JC3 as seen below, it must work.

(not like this PORT=50200 (SAPSYSTEM) 00 , be carefull)

icm/server_port_0 = PROT=HTTP , PORT=50100, TIMEOUT=60 , PROCTIMEOUT=600

Former Member — Thu, 03 Mar 2016 09:31:57 GMT

Dear Yuksel AKCINAR,

thank you for your reply. Now i have added the line

icm/server_port_0 = PROT=HTTP , PORT=50100, TIMEOUT=60 , PROCTIMEOUT=600

to the instance prifile of the JM3 instance by using notepad. I restarted the JAVA Instance.

is that doing ok?

it takes no effect at the moment, but i think it is clear, because the port is already in use at the moment.

It is a production system, i will do that on Sunday and give feedback as soon as possible.

Kidn regards,

Klaus

Re: SAP Web Application Server Port

yakcinar — Thu, 03 Mar 2016 09:44:51 GMT

Hello Klaus,

I was going to advise you,

1- Configure all instances (ABAP+JAVA) port parameters as described in below link.

icm/server_port_&lt;xx&gt; - Internet Communication Manager (ICM) - SAP NetWeaver - SAP Library

2- Stop all instances

3- Then start again.

In addition;

* You can also check port usages from SAPMMC Tool Access Points tree element of each instance.

* You can restart ICM of and ABAP instances on SMICM transaction Administration menu without restarting the instance

Waiting for feedback.

Yuksel AKCINAR

Dear Yuksel AKCINAR,

thank you for your reply.

Now i have restarted the ICM in the ABAP Instance and the port is free now. I checked it with Netstat.

As you mentioned i added the line

icm/server_port_0 = PROT=HTTP , PORT=50100, TIMEOUT=60 , PROCTIMEOUT=600

to the instance profile of the JM3 instance by using notepad. I restarted the JAVA Instance.

Then i checked the Ports in the SAPMMC Tool Access Points as you toled, but 50100 is still not available.

I checked the ICM Parameters in the ABAP Stack using rspfpar and i got following values:

icm/server_port_0

PROT=HTTP,PORT=8000,TIMEOUT=2400, HOST=xxx, EXTBIND=1

icm/server_port_1

PROT=HTTPS,PORT=0443,TIMEOUT=2400, HOST=xxx, EXTBIND=1

icm/server_port_2

PROT=SMTP, PORT=0025,TIMEOUT=2400,HOST=xxx,EXTBIND=1

Is there in JAVA Stack a possibility to add the ICM Parameters through a web interface?

I do not understand why it will not work now.

Kind regards,

Klaus

Hello Klaus,

You can use icm monitor from SAP MMC. For administration of icm you need to sign in.

You can create a user for signin using below first link.

The others are useful for icm.

Check active services in ICM admin screen on SAP MMC.

When you login you will have chance to "Change Service, Add Service, Activate/Deactivate Service, Delete Service"

Creating Administration Users - Internet Communication Manager (ICM) - SAP NetWeaver - SAP Library

Using the Web Administration Interface - Internet Communication Manager (ICM) - SAP NetWeaver - SAP Library

Using the Command Line Programs icmon and wdispmon - Internet Communication Manager (ICM) - SAP NetWeaver - SAP Library

Dear Yuksel AKCINAR,

thank you for your reply. I found this point only in the ABAP Instance, not in the JAVA Instance.

I cannot see the JAVA Ports there. Any other Idea what i can try?

Kind regards,

Klaus

Hello Klaus,

As you may see I sent the picture from my Java instance NW 7.4.

What is the version of your Java system?

There must be an icm node in SAP MMC.

Did you check dev_icm, dev_disp, dev_ms trace files of your Java system?

Regards,

Yuksel AKCINAR

Re: SAP Web Application Server Port

Reagan — Thu, 03 Mar 2016 12:14:33 GMT

You have two separate stacks. (ABAP separate and Java separate). You cannot monitor or administer the Java stack from the ABAP stack using Tx SMICM. Have you checked the ICM log of the J2EE stack to see if the HTTP service was started? If you have set the ICM profile parameters correctly then check what is happening to the port. Check using jcmon/jsmon tool for the port.

Former Member — Thu, 03 Mar 2016 12:22:51 GMT

Dear all,

it is a 7.01 system and ABAP and JAVA is separated.

Where can i find the JAVA ICM log?

Kind regards,

Klaus

Re: SAP Web Application Server Port

yakcinar — Thu, 03 Mar 2016 12:28:47 GMT

Hello Klaus,

Check work directory of the Java instance for dev_icm, dev_disp, dev_ms files. (drive:\usr\sap\JC3\<Instance>\work)

If you cannot find sthg attach them to this discussion.

Regards,

Yuksel AKCINAR

Re: SAP Web Application Server Port

Reagan — Thu, 03 Mar 2016 12:29:07 GMT

The ICM log file should be present in the work instance directory. In your case it should be

<Drive>:\usr\sap\JM3\JC01\work\dev_icm

Re: SAP Web Application Server Port

Former Member — Thu, 03 Mar 2016 12:29:52 GMT

Please check dispatcher Ports properties for http service in configtool or Visual Administrator. Also please attach dev_dispatcher log file.

Re: SAP Web Application Server Port

Isaias_SAP — Thu, 03 Mar 2016 12:29:57 GMT

Hello Klaus,

The trace files are always located at the "work" folder of the instance (/usr/sap/JM3/J02/work).
