Yes, thanks SudhakarReddy, I have this solution in mind (i.e. compiling pljava from sources against my own glibc/OS) but I have to know from which version of pljava to start (e.g. 1.4.3, 1.5.0, 1.5.1b ...?) ! So could someone tell me which version pf pljava is shipped with pega 7.2.2 (because this is not mentioned in the ResourceKit)
PLJava is specific to the version of Postgres it was built against along with any other dependencies such as glibc. The correct answer is for them to update their version of glibc. The pljava.so binary for postgresql 9.5 which is shipped with the Pega 7.2.2 instllation media is GLIBC version 2.12.
