Netweaver CE Basics for MII

This section contains a collection of links that relate to Administration, Configuration, Installation and Troubleshooting Netweaver CE as it relates to MII.  A downloadable guide with similiar information can be obtained here




Administering Composition Environment

Provides an overview of tools such as NWA (SAP Netweaver Administrator), Config Tool, Configuration Editor, SAP MMC and basic administration tasks in the CE environment.

NWA Overview

Help documentation as it relates to all of the options within NWA (SAP Netweaver Administrator).  This is organized in the same order as the menus found in NWA.


Log Configuration:  Available by navigation to Problem Management -> Logs and Traces -> Log Configuration within NWA.  The MII log configuration can be changed by setting the "Show" option to "Tracing Locations" and then navigating Com -> sap -> xmii.  It is recommended that production systems under normal operations have the log level set to Error.  For debugging scenarios Info or Debug should be utilized.

Log Viewing:  The MII application logs can be found in both the applications_<nn>.log and the defaultTrace_<nn>.log, which can be accessed in multiple areas

  •  Application server log - \usr\sap\<SID>\<instance name>\j2ee\cluster\server<n>\log
  •  SAP Management console
  •  NWA - available by navigating Problem Management -> Logs and Traces -> Log Viewer
    Using "Show View" selected either SAP Logs or Default Trace.  The "Show View Properties" will open options to filter the log view.  Using "Filter by Content" select "Application" - "contains" and type "xmii", then apply the filter.

User Management

Provides steps neccesary for performing functions related to user administration such as configuration and adding and/or activating different types of users.  Roles related to MII are:

  • SAP_XMII_Administrator: Users assigned to this role have the same permissions as users assigned to the SAP_XMII_User and SAP_XMII_Developer roles. They also have administration access, with the following exceptions: NWDI configuration read and write, encryption
    configuration, and import and export of configuration data.
  • SAP_XMII_Developer: Users assigned to this role have access to the SAP MII Workbench and some administration screens, such as Time Periods, Connection Store Editor, andCredential Store Editor.
  • SAP_XMII_DynamicQuery: Users assigned to this role have permission to run dynamic queries (queries without a query template). By default, this permission is granted to users assigned to theSAP_XMII_Developer role but not the SAP_XMII_User role. You can assign this role to specific or all users.
  • SAP_XMII_Read_Only: Users assigned to this role have read permission for administration screens and access to the SAP MII Workbench without save permission unless specifically granted.
  • SAP_XMII_Super_Administrator: Users assigned to this role have access to everything with no limitations.
  • SAP_XMII_User: Users assigned to this role have read access but no access to administration screens or the SAP MII Workbench.

Action Permissions

A listing of actions defined within the UME (User Management Engine) that provide access to certain MII functions.

Java System Reports

Java System Reports provide metrics and alerts relating to system performance and errors.  The reports can be helpful when troubleshooting performance problems and during application tuning.  Several charts and reports are delivered by defaults relating to items such as memory usage, thread counts, etc.




Configuring the log in screen

Provides the steps necessary to customize the Netweaver login screen.


SAP MII Installation guide which contain the necessary steps to setup a JRA connection.  When a connection is defined three types show up in MII;

  • nonGlobalTX -  connections which are acquired from connection factory with this setting will not be enlisted into distributed(JTA) transactions. This is SAP specific setting.  Non-shareable, non-global trx, application authorization 
  • shareable - only one physical connection will be created and will be shared even if the application wants to acquire two.  Shareable, global trx, application authorization
  • unshareable - any connection that is acquired will be it's own separate physical connection.  Non-shareable, global trx, application authorization


Provides the steps necessary to configure topics that can then be used within a MII transaction to send/read JMS messages.


The IDOC/RFC listeners can be configured by opening NWA and navigating to Configuration Management -> Infrastructure - > Application Resources.  Using the "Show" option select Resource Adapters.  The listeners will be labled as XMIIIDOC<n> and XMIIRFC<n>.  After selecting one change the Resource Details tab to Properties.  The property MaxReaderThreadCount needs to have of at least 1.  This property is basically the connection pool setting of the listener, assigning a large value may be wasting resources where as setting a small value may require a wait period to obtain a connection.  If an invalid configuration is entered the IDOC/RFC connector will be stopped.  At this point in NWA you will have to navigate to Operation Management -> System -> Start & Stop, select the Java EE Applications and search for the appropiate connector and restart it.  They are named in the following format sapjra~xMIIIDOC<n> or sapjra~xMIIRFC<n>


In addition to this link the NWDI Configuration Guide for MII 12.1  and MII Install guide should be reviewed for specifics that relate to MII.  MII Project Building and Deploying should also be reviewed.

Resource Management

Provides an overview for managing JDBC Drivers and DataSources, and JCA and JMS Connection Factories.
