Pre-Con Ed: Optimizing System & Network Performance Part I: What's New in CA SYSVIEW® 14.2
0 likes470 views
The document discusses new features in CA SYSVIEW 14.2 for optimizing mainframe system and network performance. It describes the Operational Intelligence feature which uses predictive analytics to detect anomalies earlier. It also describes the Mainframe Team Center, which provides a modernized user interface and consolidated view of information across tools to help generalists and experts collaborate more efficiently to identify issues and remediate them faster. Additional core updates in CA SYSVIEW 14.2 include enhancements to WLM monitoring and data collection, support for larger CICS logging buffers, and improved CICS storage monitoring.
