This release introduces the coreadm command, which provides flexible core file naming conventions and better core file retention. For example, you can use the coreadm command to configure a system so that all process core files are placed in a single system directory. This means it is easier to track problems by examining the core files in a specific directory whenever a Solaris process or daemon terminates abnormally.
Two new configurable core file paths, per-process and global, can be enabled or disabled independently of each other. When a process terminates abnormally, it produces a core file in the current directory as in previous Solaris releases. But if a global core file path is enabled and set to /corefiles/core, for example, then each process that terminates abnormally would produce two core files: one in the current working directory and one in the /corefiles directory.
By default, the Solaris core paths and core file retention remain the same.
See "Managing Core Files (coreadm)" and coreadm(1M) for more information.
