To support Client-Library connection caches, EAServer includes a native threaded version of Open Client Client-Library using the shared library libjct_r.sl. This version supports all features in Open Client 11.1, plus the high availability and failover and wide table features from Open Client 12.5 (varchar/varbinary columns more than 255 bytes long and tables with more than 255 columns). You can use these Opent Client 12.5 features only when connected to Adaptive Server® Enterprise version 12.5 or later.
