|Oracle Solaris Cluster Data Services Planning and Administration Guide Oracle Solaris Cluster 4.0|
This chapter provides planning information and guidelines to install and configure Oracle Solaris Cluster data services. This chapter contains the following sections.
For introductory information about data services, see Oracle Solaris Cluster Concepts Guide.
Oracle Solaris Cluster software can provide service only for those data services that are either supplied with the Oracle Solaris Cluster product or are created with the Oracle Solaris Cluster data services application programming interfaces (APIs).
If an Oracle Solaris Cluster data service is not provided for your application, consider developing a custom data service for the application. To develop a custom data service, use the Oracle Solaris Cluster data services APIs. For more information, see Oracle Solaris Cluster Data Services Developer’s Guide.
Note - Oracle Solaris Cluster does not provide a data service for the sendmail(1M) subsystem. The sendmail subsystem can run on the individual cluster nodes, but the sendmail functionality is not highly available. This restriction applies to all the sendmail functionality, including the functionality of mail delivery and mail routing, queuing, and retry.
