Upgrading high availability

Use “en” for the language_code or you may omit the parameter completely as “en” is the default.

Note Template XML should be upgraded on all Job Scheduler servers upgraded to Adaptive Server version 15.0.1. Do not install them on pre-15.0.1 servers or servers where Job Scheduler is not installed.

Upgrading high availability

Using the following steps to upgrade high availability-enabled Adaptive

Server in active-active configuration:

1 Drop the high availability companionship. On the secondary server, use isql:

sp_companion <primary_server_name>, "drop" go

2Use the cluster system command to stop monitoring resources associated with Adaptive Server on each cluster node.

3Follow the upgrade steps in “Upgrading to Adaptive Server 15.0.2” on page 68 to upgrade each of the Adaptive Servers separately.

4Run the new Adaptive Server installmaster script against the newly upgraded Adaptive Servers.

5Run the new Adaptive Server installhasvss script against the newly upgraded Adaptive Servers.

6In the new Adaptive Server installation area, follow the instructions in Using Sybase Failover in A High Availability System to configure the permission and ownership for $SYBASE/$SYBASE_ASE/bin/sybha and $SYBASE/$SYBASE_ASE/install/sybhauser.

7In the new Adaptive Server installation area, modify high availability-related files such as the RUN_server_file, and the SYBASE.csh and SYBASE.sh files, if those files are required on that cluster platform.

8Reconfigure each resource associated with Adaptive Server depending on platform-specific requirements. For example, on Veritas Cluster, the HAase resource properties, the RUN_server_file, and Sybase_home need to be updated.

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.
