Chapter 9. Virtual File Systems, Swap Space, and Core Dumps


The following test objectives for exam 310-202 are covered in this chapter:

Explain virtual memory concepts and, given a scenario, configure and manage swap space.

  • The Solaris operating environment can use disk space, called swap areas or swap space, for temporary memory storage when a system does not have enough physical memory to handle currently running processes. A system's memory requirements change, and you must be knowledgeable in swap space management in order to monitor these resources and make ongoing adjustments, as needed.

Manage crash dumps and core file behaviors.

  • You can configure the creation and storage of crash dump and core files, depending on the requirement. You can create application core files on a global or per-process basis. You must be able to customize the configuration according to various circumstances.

Explain NFS fundamentals, and configure and manage the NFS server and client including daemons, files, and commands.

  • Network File System (NFS) facilitates the sharing of data between networked systems. NFS servers share resources that are to be used by NFS clients. This chapter describes NFS and the tasks required to administer NFS servers and clients.

Troubleshoot various NFS errors.

  • You must have a thorough understanding of the problems that can arise within the NFS client/server process and how to address them. This chapter describes a number of problem areas and what to do in order to rectify them.

Explain and manage AutoFS and use automount maps (master, direct, and indirect) to configure automounting.

  • AutoFS allows NFS directories to be mounted and unmounted automatically. It also provides for centralized administration of NFS resources. This chapter describes AutoFS and how to configure the various automount maps.
