names can be provided at the same Internet Protocol (IP) address, which you can manage using CICS system commands. Static responses can be provided for HTTP requests, formed from a document template or hierarchi- cal file system (HFS) file. This means that you can write CICS application programs to use a common protocol for
Improved connected, but inactive, sockets allow many more clients to connect to each CICS system. Using an internal
Improvements to SSL support
CICS Transaction Server, Version 3.1 introduces a range of improvements to security. Besides its existing support for Secure Sockets Layer (SSL), Version 3.0, CICS Transaction Server now supports the Transport Layer Security (TLS), Version 1.0 protocol. This includes support for the Advanced Encryption Standard (AES) cipher suites that offer
Resource definitions for TCP/IP service and CORBA Server are enhanced to allow the user to specify the precise list of cipher suites to be used in the negotiation. This capability is also included in the new uriMAP resource definition. To support management of these new capabilities and resources, CICS Transaction Server, Version 3.1 includes new system programming interface (SPI) commands.
CICS Transaction Server, Version 3.1 now supports certificate revocation lists (CRLs) when negotiating with clients, allowing any connections using revoked certificates to be closed immediately. A new transaction, CCRL, is provided to update the CRL in the Lightweight Directory Access Protocol (LDAP) server. These negotiations offer more flexibility. Now, you can specify a minimum, as well as a maximum, encryption level to negotiate with particular users.
You can also specify whether session IDs are shared across an IBM Parallel Sysplex® environment, improving the current use of the cache at the
An increased number of simultaneous SSL connections can now be used, as a result of the introduction of support for pthreads within the IBM Language Environment® enclave from which system SSL is invoked. With this support, your system can achieve better throughput and improve the support for new functions such as Web services.
