SAP Note 1581595 - rfcexec or startrfc fail after upgrade

Component : RFC -

Solution : https://service.sap.com/sap/support/notes/1581595 (SAP Service marketplace login required)

Summary :
SAP Note highlights changes in the delivery of RFC SDK programs like rfcexec from Release 720 onwards due to security concerns. The programs startrfc and rfcexec, identified as security risks, are omitted from the kernel and classic RFC SDK packages. Users must now install the NetWeaver RFC SDK to use these programs. Configuration details including the update of LD_LIBRARY_PATH and usage of security files (rfcexec.sec) are provided, ensuring these programs operate within secured environments. Additionally, operational guidelines on running rfcexec as a registered or started server are outlined.
