APPENDIX A Alternative Installation Methods

In either case it is possible to custom configure the servers as well as being able to select a typical install and use the default configuration values.

Except for the absence of the GUI screens all actions of the Installer are the same and the result of an installation in silent mode is exactly the same as one done in GUI mode with the same responses.

Note The value for -options,-options-template, and -options-record must specify an absolute path.

Installation in silent mode can fail when a response is required from the user. Such a response is required when files already exist on disk and appear to be newer than the files the installer is attempting to install, or when files have been modified by the user.

Set the following options at the command line level to specify actions to take when installing in silent mode:

•replaceExistingResponse – stores your response to whether you want to replace a file that currently exists on your system with the one being installed.

•replaceNewerResponse – stores your response to whether you want to replace a file that currently exists on your system with the one being installed if the existing file is newer than the file being installed.

•removeExistingResponse – stores your response to whether you want to remove a file that currently exists on your system.

•removeModifiedResponse – stores your response to whether you want to remove a file that has been modified since installation.

Any of these options can be specified on the command line or within the options file as follows:

-G <option>="<value>"

Valid values are:

•yesToAll

•yes

•noToAll

•no

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.
