Upgrading the server

CHAPTER 5 Upgrading Adaptive Server

Set the OLDSYBASE_ASE variable to the SYBASE_ASE appropriate to your older server. If you are upgrading from 12.0 for example, it should be ASE-12_0. If your preupgrade version is earlier than 12.0, specify it as null:

set OLDSYBASE_ASE=""

This is required if you are using sybatch.exe to perform your upgrade.

Install the new Adaptive Server into the same directory as the Adaptive Server you are upgrading.

This section covers the upgrade process, and outlines the following tasks:

•Installing version 15.0.2 software on the target computer. See Chapter 2, “Installing Adaptive Server.”

•Upgrading the servers with syconfig or sybatch.

•Post-upgrade tasks, including how to enable earlier versions of programs and databases, allowing them to utilize the new version’s functionality.

Note The installation procedure for Sybase Central and the Adaptive Server plug-in for Sybase Central has changed. Beginning with version 12.0, Adaptive Server uses the following locations: Sybase Central in the x:\Program Files\Sybase\Sybase Central\win32 directory and Adaptive Server plug-in for Sybase Central in the %SYBASE% directory. Earlier versions used the x:\sybtools directory. The Installer modifies your CLASSPATH, PATH, Profiles, and Registry entries to these specific new locations.

To upgrade the server after you have installed the new software:

1Run Start Programs Sybase Adaptive Server Enterprise Server Config.

2Click Upgrade Adaptive Server in the Configure Sybase Servers window.

3Enter the name of the old Sybase directory. Enter the name of the old Adaptive Server directory, such as ASE-12_0. Enter the old OpenClient Server directory such as OCS-12_0.

4Click Continue.

5In the Existing Servers window, select the Adaptive Server to upgrade and choose Continue.

15.0.2 specifications

Sybase 15.0.2, a product of the Sybase corporation (now SAP), is a relational database management system (RDBMS) that provides robust solutions for data management, security, and performance. This version builds upon its predecessors, offering improved features and enhancements that cater to both enterprises and developers.

One of the standout features of Sybase 15.0.2 is its advanced performance capabilities. The version introduces optimization enhancements such as the Query Optimizer, which is designed to ensure efficient execution of complex queries. This optimizer analyzes SQL statements and tables to choose the most efficient means of retrieval, thus reducing execution time and improving the overall performance of the database.

Sybase 15.0.2 supports improved scalability, allowing organizations to handle increased workloads without significant changes to their infrastructure. This scalability is crucial for businesses experiencing growth, as it ensures that performance remains consistent and reliable.

Another notable characteristic is the robust security architecture integrated within Sybase 15.0.2. The system includes features like data encryption, user authentication, and authorization mechanisms, making it suitable for environments that handle sensitive information. Database administrators can implement fine-grained access controls to manage user permissions effectively.

Moreover, Sybase 15.0.2 boasts support for a wide range of programming languages and frameworks. This versatility allows developers to build applications using their preferred tools, promoting productivity and ease of integration into existing systems. The database management system also supports various platforms, including Windows and UNIX, enabling diverse deployments across different environments.

In addition to these technological enhancements, Sybase 15.0.2 emphasizes data integrity through its robust transaction management system. It implements the ACID properties (Atomicity, Consistency, Isolation, Durability) to ensure that all database transactions are processed reliably, thereby maintaining the integrity of data even in high-transaction scenarios.

In conclusion, Sybase 15.0.2 is a feature-rich RDBMS that combines performance, scalability, security, and flexibility. Its advanced capabilities not only enhance data management for organizations but also provide a solid foundation for developers seeking to create efficient and secure applications. The improvements in this version make it a compelling choice for enterprises looking to optimize their database operations in an increasingly data-driven world.
