Features Added in Enterprise Server 2.1 Update 1

Enterprise Server

The following new features and enhancements are available:

Enterprise Server Clustering allows the scaling-out of work units, so that an increased number of operating system images can share the workload, resulting in high-performance, multi-system data sharing across all platforms.
Historical Statistics Facility
The Historical Statistics Facility has been extended to include the generation of JCL file records, increasing the amount of information customers have available to assist them in monitoring and tuning their Enterprise Server installations.
Recovery of in-doubt XA transactions
Some events in XA environments can result in ‘in-doubt’ transactions, where all parts of a composite transaction are not committed through all participating resource managers. The recovery of such in-doubt transactions is now supported.
SSL Support for the CICS Web Interface
Enterprise Server now allows clients and servers to identify themselves through X.509 certificates and participate in SSL-enabled conversations.
