Abstract

Disclosed is a design for managing the installation of certain resource definitions into a CICS system which avoids certain difficulties associated with the need to invoke a Java Virtual Machine as part of the installation processing: The standard method for installing resource definitions into a running CICS system is for the Resource Definition Online (RDO) infrastructure code to read the definition record from the CICS System Definition (CSD) file and invoke the appropriate CICS domain gate for each resource. The domain code then adds the new resource to its state and passes it to the Catalog Domain to record for warm restart recovery. In some cases, Directory Manager is also used to record the new resource. However in the CICS implementation of Enterprise JavaBeans (TM) (EJB) support there are cases where it is necessary to invoke a Java Virtual Machine (JVM) as part of the resource installation process. These are: CorbaServer install where a directory on HFS (Hierarchical File System, the MVS implementation of the Unix (TM) file system) needs to be created (or emptied).
