  1. Copy the updated native library libsapjco3.so file in  $SL_ROOT/ldlib (usually /opt/snaplogic/ldlib) folder on every node in the Snaplex.
    Note: For Snaplexes with multiple nodes, make sure to install the library on every node.

  2. Restart all the nodes in the SanplexSnaplex.

Note

Update the following native library files under $SL_ROOT/ldlib/:

  • libsapjco3.so for Linux-based JCC nodes.

  • sapjco3.dll for Windows-based JCC nodes.

This is due to the parameter change in JCo (Java Connector) from 3.0 to 3.1. According to the JCo documentation, parameter jco.use_repository_roundtrip_optimization is used to optimize the metadata lookups.

In JCo 3.0.6, the default value of the parameter is 0, whereas, in JCo 3.1.10, the default value of the parameter is 1.
In the 3.0 driver, if the function module is not remote-enabled, the driver still calls the function module and the SAP server informs you regarding the failure. However, in the latest driver, if the function module is not remote-enabled, the JCo would detect it in advance, and the Snap fails.

Important: If you want to revert to the previous behavior, the JCo properties could be set through the jvm_options:

jcc.jvm_options=Djco.use_repository_roundtrip_optimization=0
