4 Binding Ports Lower Than 1024 on UNIX With the Internet Communication Manager (ICM) you can bind ports with numbers 0 up to and including 1023 (well known ports) on Unix systems too. The external binding program icmbnd included in the standard delivery is used for this. Usually the ICM itself binds the ports. If you want to use icmbnd to bind configured ports, change the parameter specification for icm/server_port_<xx> in the profile (transaction RZ11). Integration On Unix systems only users with superuser authorizations can bind ports with numbers lower than For this reason either the ICM process must be provided with these authorizations, or the port must be bound by an external program and then the listen socket transferred to the ICM. Activating External Binding To ensure the ICM itself does not attempt to bind the port, you specify an additional option when you are configuring ports with icm/server_port_<xx>: EXTBIND=1 The format of this parameter is: icm/server_port_1 = PROT=HTTP, PORT=8080, TIMEOUT=30, EXTBIND=1 Usually icmbnd is called directly from the ICM, though the program can also be called from external systems to make new ports known to the ICM. icmbnd can also be used to bind ports >= 1024, but then the startup time of the ICM is longer. icmbnd is also available for Windows. As the user <sid>adm can bind any number of ports on this system, there is no need to use the icmbnd here. SAP AG Delta 7 Course Overview - 4

5 icm/plugin_<xx> This parameter is used to specify the protocols supported by the ICM. <xx> must be specified in ascending order from 0. A protocol is specified by the name of the protocol (for example, HTTP, HTTPS) and a shared library (plug-in) for the protocol. The plug-in can be associated with the parameter icm/server_port_<xx> at one or several ports icm/server_port_<xx> Use You can use this parameter to specify the service/port that is to be used for a protocol. Either the service name or the port number can be specified. You can also determine additional service properties. This is described in the procedure below. Prerequisites A plug-in for the protocol must be specified in the parameter icm/plugin_<xx>, as otherwise the service cannot be started. There cannot be more than one service allocated to a single port. Also, a service cannot be started if another program is using the port or service. SAP AG Delta 7 Course Overview - 5

6 Monitoring the Status of the ICM Use The ICM monitor provides various functions for monitoring the status of the ICM and for detecting any possible errors. Functions You can find the functions described here in the Go To menu. Trace files To display or reset the trace file dev_icm, choose Go To Trace file or Go To Trace Level. You can also set the trace level here (values can be between 0 and 3; the default is 1). You can also display just the start or the end of the file (the first or last 1000 lines). This is a very useful function for large files. Choose Goto Trace file Display start or Display End. If you want to view the trace file of the external binding program icmbnd, choose Goto Trace file Display Dev_icmbnd. Parameters Choose Goto Parameters to display or change the ICM profile parameters. If you choose Change, you can display the RZ11 documentation for every parameter that is executed by placing the cursor on the parameter name and choosing Documentation. The value field is ready for input for those parameters that can be changed dynamically. Note that with dynamic changes, these are lost the next time the instance is started.

7 The Transaction SMICM (ICM Monitor) is in comparison with SM51 (Instance Overview) and it contain also a work process Overview. The Advantage in the SMICM is that you can restart the ICM without restarting the SAP Instance (no bounce of the system). For the ICM Usage in the web Application Server it in mandatory to update the basis Kernel 7.00 regularly, e.g. the Released Kernel support Stacks. The ICM get his updates together with the Kernel Patches. Please check also the interfere between Kernel and ICM. In the 6.x it happened sometime that Kernel patches produced errors in the web interface. Additional Notes for Settings/Performance of the integrated ITS: Note Timeout for ICF services based on ITS Note Integrated ITS: Configuration Parameters Note SAP Integrated ITS updates for NetWeaver 2004s (7.00) Note Integrated ITS, mimes cache control: max-age Note OutOfMemory due to http response compression Note WebAS Java 7.00 SP06 - List of corrections Note Http transmission of XI messages with huge payload fails SAP AG Delta 7 Course Overview - 7

8 Additional Notes for SSO/SSF Settings Here on this page you see the Steps to check the SSO configuration for the WAS web reporting for BI. By Default, only HTTP is active you will get a prompt from your web browser as soon you want to log on to your WAS Server with The Disadvantage is, that you only get two fields: Username and Passwords. If you want to have additional Functionality like Language field or changing Password you need to enable the SSO configuration on the system. This configuration is also the necessary Pre Requisites to integrate the BI system into the EP 7.0 Portal. Note BEx Web Java: Analysis of communication/logon problems Note Checking the SSO configuration Note Collective Note: Analyzing issues with Single Sign On (SSO) Note Central note on WS Security (ABAP 7.00 and later) Note Select the right version of an SAP security toolkit Note Common error messages when setting up Single Sign-On Load Balancing with HTTP/HTTPS: Note Message server: Status code for redirect requests Note Load balancing using message server through HTTPS SAP AG Delta 7 Course Overview - 8

This is also valid for Windows based systems (no read only permission). If you forgot to change the permission after you restarted the system, you have to stop the SAP system and change the permission before SAP is restarted. You will have no effect when you only restart the ICM service. The SMTP service will be used for various reason like in SEM or in the process chains for BI. It is also used together for the Information Broadcasting, the new feature of BI 3.x and above. SAP AG Delta 7 Course Overview - 9

10 Some more Informations about SSL/SSO: Check the library sapcrypto.<ext> (o, so, sl, dll) if you are using the latest version which you can download from You must use a s-user ID for the download. See notes and for details. The library must have 775 or on W2K read permission before restarting SAP. Check for the right parameters in the SAP instance profile (Example Windows): sec/libsapsecu = g:\usr\sap\bi1\sys\exe\run\sapcrypto.dll ssl/ssl_lib = g:\usr\sap\bi1\sys\exe\run\sapcrypto.dll ssf/ssfapi_lib = g:\usr\sap\bi1\sys\exe\run\sapcrypto.dll ssf/name = SAPSECULIB Check with the transactions: STRUST - Trust Manager STRUSTSSO2 - Trust Manager for Logon Ticket SAP AG Delta 7 Course Overview - 10

12 More Information can be found in the following Notes: Note : Digital signatures with SAPCRYPTOLIB Note : Problem analyze with HTTPS-Communication Note : Checking the SSO configuration Note Common error messages when setting up Single Sign-On Configuration check SAP delivers the sso2test.htm BSP application. You can use this application to check whether an SSO2 cookie can be created. Start Transaction SE80 'SYSTEM' BSP application Pages with flow logic Right-click on sso2test.htm Test Follow the instructions on the screen You can also execute the following JavaScript command from the address bar of your Internet browser to check whether an SSO2 cookie currently exists: javascript:alert(document.cookie); As a result, all current cookies are issued in an alert box. If an SSO2 cookie exists, an entry would have to exist that begins with 'MYSAPSSO2=...' SAP AG Delta 7 Course Overview - 12

13 This Configuration step is done automatically, if all pre requisites are fulfilled to start and run the NetWeaver Administrator Template Installer (CTC). System parameter/settings login/accept_sso2_ticket = 1 login/create_sso2_ticket = 2 icm/host name full To enable the Internet browser accept the SSO2 cookie, you must enter a fully qualified host name in accordance with notes and SAPSECULIB / SAPCRYPTOLIB You must use the SAP Security Library or the SAP Cryptographic Library. Transaction STRUST Transaction STRUSTSSO2 In this transaction, you define which systems are meant to accept logon tickets. This is necessary, for example, when you want to access data from one system of a BI application to another application of another system, without having to log on again.

15 See online help /frameset.htm for more details of the configuration. Configuring the web dispatcher for SSO: c/content.htm Setting Up and usage of the web dispatcher: Whenever you want to scale Java Instances like the abap instances (central instance with application servers) the web dispatcher is needed for the load balancing If SAP Systems are accessed from the Internet via DMZ, the abap and java Instances must be available via web dispatcher. These addresses are later used instead of the real server addresses from abap and java. You can modify the CTC BI-Java Template before you start the configuration web dispatcher for Abap used in the entry SAP_BW in the Systemlandscape in Java web dispatcher for Java used in the table entry RSPOR_T_PORTAL in Abap SAP AG Delta 7 Course Overview - 15

16 Note Inactive services in the Internet Communication Framework This is the overview web tree for the web services. Black indicates that the service is active Grey would indicate that the service in inactive Blue indicates that the service is active, but the underlying service is still inactive. Use the Feature to activate all underlying services also (Recommended way even when no service is under the active service.) Note that for the SEM cockpit and for the WAS standard login also some services in the basis section had to be active. The alias public should also turned to be active You can also define your own aliases to have shorter web URL s, e.g. /sap/bw/bex /web SAP AG Delta 7 Course Overview - 16

17 Please make sure that the whole tree in BI has a active compression flag, especially the sap/bi/bex and the sap/bi/mime tree. You can do this once and transport this settings through your system Landscape Please note that sometime corrections in the basis support packages an deactivate the service by accident. Than you simply have to turn the service back to active. SAP AG Delta 7 Course Overview - 17

18 When you change something in a service, the service keeps active all the time. You don t have to restart the service. The Button Test Service switches directly to the web output without having a web query ready. Note Which BEx Analyzer version is called by RRMX?
