You can avoid many SAP issues by meeting the basic prerequisites required to integrate your SAP system with the Sybase Unwired Platform development environment.
Server prerequisites
Check the following for each Unwired Server in the production configuration:
- Verify that the SAP version to which you are connecting is supported. Check the Sybase Unwired Platform Installation Guide for supported versions.
- Verify you downloaded the correct versions of sapjco.jar, librfc32.dll, and sapjcorfc.dll from the SAP Web site. Also verify that you installed the files correctly in the installation directory. See System Administration for Sybase Unwired Platform > Environment Setup > EIS Connections > Preparing Unwired Server to Connect to SAP Servers. These files are critical for establishing connection.
- On Windows 7, Windows Vista, and Windows Server 2008, verify you downloaded the correct versions of msvcr71.dll and msvcp71.dll from the SAP Web site. Also verify that you installed the files correctly in the <WINDOWS_HOME>\System32 diretory. See System Administration > Environment Setup > EIS Connections > Preparing Unwired Server to Connect to SAP using Java Connectors
- If you are operating in a clustered production environment, you must also enable SAP mobile business objects to connect to an SAP R/3 system that uses a router. See System Administration for Sybase Unwired Platform > Environment Setup > EIS Connections > Preparing Unwired Server to Connect to SAP Servers.
- If you are using a connection pool, make sure it is configured correctly. See System Administration for Sybase Unwired Platform > System Reference > EIS Data Source Connection Properties Reference.
- If you are using the SAP Data Orchestration Engine Connector (DOE-C), make sure it is configured correctly. See System Administration for Sybase Unwired Platform > System Reference > EIS Data Source Connection Properties Reference and its SAP-related sub-topics.
Development prerequisites
Check the following for each Unwired Server in the development environment:
- Verify that the SAP version to which you are connecting is supported. Check the Sybase Unwired Platform Installation Guide for supported versions.
- Verify you downloaded the correct versions of sapjco.jar, librfc32.dll, and sapjcorfc.dll from the SAP Web site. Also verify that you installed the files correctly in the installation directory. See Sybase Unwired WorkSpace - Mobile Business Object Development > Configure > Configure - Eclipse Development Environment > Creating a Data Source Connection Profile > Creating an SAP Connection Profile > SAP JCO Connector Prerequisites for Development.
