Issue/Introduction

Description:

The SAP agent will crash on UNIX platforms after running for about 30 minutes to an hour. This can happen because the JCO is not correctly installed/applied.

Agent and SAP logs will show errors like these:

[CRITICAL] [Thread-23, 5, main] CybSAPJobManager.requestProcessedNotify[:1132] - SAP ERROR: Connecting -Unexpected Problem: JCO.classInitialize: Could not load middleware layer com.sap.mw.jco.rfc.MiddlewareRFCJCO.nativeInit:

Solution:

To install the SAP Java Connector:

Log in to SAP Service Marketplace.

Navigate to SAP Java Connector, Tools & Services.

Download the latest version of SAP JCO for your operating system.

Note: For HP-UX systems, download 32bit JCO, even if the OS is 64bit.

• Stop the agent if it is running.
  
  
• Remove any previous version of the JCO library from the agent installation directory.
  
  
  1. For example, to remove SAP JCO 2.1.6, complete these steps:
     
     
     1. Delete the following files and links from the agent installation directory:
        
        
        • *2.1.6.*
          
          
        • librfccm* and libsapJCOrfc.* (UNIX)
          
          
        • librfc32.dll and sapJCOrfc.dll (Windows)
          
          
     2. Delete the sapJCO-2.1.6.jar file from the jars/ext subdirectory of the agent installation directory.
        
        
• Extract the sapJCO.jar file to jars/ext subdirectory of the agent installation directory.
  
  
• Extract the following libraries to the agent installation directory:
  
  
  1. On UNIX, extract librfccm and libsapJCOrfc.
     
     
  2. On Windows, extract librfc32.dll and sapJCOrfc.dll.
     
     
• Start the agent.
