Configuring HP DCE Cells

Integrating DCE Services with MC/ServiceGuard

1. To restart the package on a specified host, enter:

cmrunpkg -nhost pkg-name

2. To reenable packet switching after halting the package, enter:

cmmodpkg -nhost pkg-name

See Managing MC/ServiceGuard for procedures on using SAM to administer MC/ServiceGuard clusters and packages.

Summary of DCE-MC/ServiceGuard Installation and Configuration

The following steps summarize the process of installing and configuring DCE with MC/Service Guard.

1.Install the MC/ServiceGuard cluster.

2.Start the MC/ServiceGuard cluster.

3.Identify and mount the shared volumes manually from the primary node.

4.Identify the hostname and IP address to be dedicated for the DCE package.

5.Manually activate the package IP address from the primary node using the cmmodnet command.

6.Configure DCE Core Services.

7.When the above configurations are complete, the DCE daemons will start up automatically. Stop them manually using dce_config.

8.Manually unmount and deactivate the shared volume.

9.Manually deactivate the package IP address from the primary node using the cmmodnet command.

10.Configure the DCE package scripts.

11.Apply the Package Configuration on the ServiceGuard cluster.

12.Start the ServiceGuard cluster.

UX DCE Software specifications

HP UX DCE Software, or Hewlett-Packard UNIX Distributed Computing Environment, represents a significant tool in the realm of distributed system architecture. Designed primarily for enterprise environments, HP UX DCE enhances the reliability, scalability, and manageability of applications over diverse networked systems.

One of the main features of HP UX DCE is its ability to integrate various computing platforms, enabling seamless communication and resource sharing across distributed nodes. This facilitates the creation of complex applications that can operate on a multitude of systems, thus enhancing operational flexibility. DCE employs standardized interfaces, which means applications written for one platform can run on any other platform that supports DCE, promoting cross-platform compatibility.

In terms of technologies, HP UX DCE utilizes Remote Procedure Calls (RPC) as a core feature. This mechanism allows different applications to communicate and invoke procedures on remote systems as if they were local calls. Additionally, DCE includes a robust security model that incorporates Kerberos for authentication, ensuring that communication between nodes remains secure and protected against unauthorized access.

Another significant characteristic of HP UX DCE is its distributed file system, which allows for transparent file access across different machines. The DCE File System (DFS) provides a unified namespace and manages data replication and consistency across distributed storage resources. This reduces the complexity of data management and enhances data availability.

HP UX DCE also supports a variety of programming languages, making it accessible for developers accustomed to different coding environments. This versatility encourages widespread adoption and innovation, as developers can leverage existing skills to create distributed applications.

Furthermore, HP UX DCE is built for high availability, ensuring that critical applications remain responsive even in the face of hardware or network failures. Its inherent component redundancy and fault-tolerant architecture are designed to minimize downtime, which is essential for mission-critical applications in enterprise scenarios.

In conclusion, HP UX DCE Software provides a comprehensive framework for developing, deploying, and managing distributed applications. Its core features such as RPC support, a secure authentication mechanism, a robust file system, and cross-platform compatibility make it a vital resource for organizations aiming to leverage distributed computing effectively. As enterprises evolve, HP UX DCE stands out as an influential solution in the dynamic landscape of distributed environments.
