The LI REQ,complib,DIAGDATA  command was introduced in R3.3 PGA2. This data is used by Grid Resiliency function, which was supported since R4.1.2. 

This command is supported only with a grid configuration and not with a stand-alone cluster. 

This command helps you monitor the health of clusters in the grid communication, which provides diagnostic information for handshake between two clusters in the grid.
