Question Robert Cemper · Nov 20 Working with Named Pipes While creating my latest examples for the JavaContest I faced the needto communicate with my code from a program in IRIS to my Java code. Communication with |CPIPE| worked as READ or WRITE but not both?In the Documentation Named PIPEs are explained rather shortly."Once open, a pipe acts like an ordinary device."

Question Robert Cemper · Oct 15 embedded Python over ECP With ECP we have the option to have a collection of Frontend instancesAll Frontend servers typically have a common Master in the backgroundConcentrating data on the Master server is the primary goal.

Is embedded Python code also stored in Globals? What is the recommended solution for a similar installation? #ECP #Embedded Python #InterSystems IRIS 1 2 0 96
