Migrating to HP DCE 1.7

Migrating an HP DCE 1.5 Server on HP-UX 10.20 to HP DCE 1.7 on HP-UX 11.0

Migrating an HP DCE 1.5 Server on HP-UX 10.20 to HP DCE 1.7 on HP-UX 11.0

See Managing HP-UX Software with SD-UX and the swcopy (1M), swinstall (1M) and swremove (1M) man pages for complete information on all aspects of HP-UX installation.

For information about migrating from HP-UX 10.x to HP-UX 11.0, see Installing HP-UX 11.0 and Updating HP-UX 10.x to 11.0 (B2355-90153).

Migration Procedures

HP highly recommends that you do a system backup before starting to do an update.

Migrating a System Without Retaining Cell Configuration

If you are migrating an HP DCE 1.5 server on HP-UX 10.20 to HP DCE

1.7on HP-UX 11.0, but you do not want to preserve your existing cell configuration:

1.Stop the cell using dce_config STOP at each cell member or run DCM from SAM to stop the entire cell.

2.Use dce_config REMOVE or run the DCM from SAM to remove the cell databases.

3.Upgrade the system from HP-UX 10.20 to HP-UX 11.0.

4.Install HP DCE 1.7 software as described in Chapter 4, and reconfigure DCE.

Migrating a System and Preserving Current Cell Configuration

If you are migrating an HP DCE 1.5 server on HP-UX 10.20 to HP DCE

1.7on HP-UX 11.0, and you want to preserve your existing cell configuration, perform the following steps:

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.
