Error description
Co-existence and Compatibility for CICSPlex SM regions interacting with CICSPlex SM 6.3 agents.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM Users. * **************************************************************** * PROBLEM DESCRIPTION: Compatibility and co-existence updates * * required for operation of previous * * CICSPlex SM releases with 6.3 CPSM * * agents. This allows compatibility * * with ATTLSAWARE support for IPIC. * **************************************************************** * RECOMMENDATION: The PTF(s) addressing this APAR should be * * applied to all CPSM CICS regions (CMAS,LMAS * * and WUI regions) and these restarted. This * * can be performed in any order. * **************************************************************** Due to changes in resource definitions included in 6.3, co-existence changes are required to be applied at earlier releases, to ensure compatibility when 6.3 CMAS and MAS agents are also active within a CICSplex. CICS TS 6.3 adds support for ATTLSAWARE for IPIC connections TCPIPSERVICE and IPCONN definitions (TCPDEF and IPCONDEF). This has included introducing SSL(ATTLSAWARE) for IPIC. To allow these definitions to be installed on earlier releases a change is required to allow co-existence for these definitions. This encompasses the following: - IPCONDEF definitions with SSL(ATTLSAWARE) - TCPDEF definitions with PROTOCOL(IPIC) and SSL(ATTLSAWARE) - IPCONN resources installed with SSL(ATTLSAWARE)
Problem conclusion
Changes have been made to ensure correct co-existence with 6.3 release MAS and CMAS agents. This allows previous releases to display and query the new SSL(ATTLSAWARE) value for these definitions and resources. Change have been made to allow 6.3 IPCONDEF and TCPDEF definitions to be installed into previous release CPSM agents, with the SSL attribute being altered to SSL(NO) when installed. This results in resources installed in this release with: - IPCONDEF resources installed with SSL(ATTLSAWARE) are installed as a IPCONN with SSL(NO). - TCPDEF resources installed with PROTOCOL(IPIC) and SSL(ATTLSAWARE) are installed as a TCPIPService with SSL(NO). When these 6.3 definitions with SSL(ATTLSAWARE) are installed in an applicable pre-6.3 LMAS region they are installed with SSL(NO). As a result if the remote partner requires a TLS/SSL connection, the connections will be rejected and these will not operate correctly. Keywords: CIC0603C/K IBM.Coexistence.CICS.V6R3
