Recovering from a failed upgrade

5Copy the 32-bit$SYBASE/$SYBASE_ASE/install/RUN_<server> file to the equivalent 64-bit$SYBASE/$SYBASE_ASE/install directory.

6Edit the RUN_server file to reflect the new location of the interfaces, configuration, and log files.

7Remove all references to the 32-bit $SYBASE directories from your $PATH definition.

8Change to the 64-bit $SYBASE directory and source the ASE150.[csh, sh] script (Bourne shell).

9Change to the 64-bit $SYBASE/install directory and execute:

startserver -f RUN_server

10 After the 64-bit server starts, run installmaster, installmodel, and installmsg.ebf.

11If you used dbccdb for dbcc checkstorage, run installdbccdb. This

re-creates some tables in the dbccdb, and you may lose history data.

12Drop and re-create all your compiled objects, such as stored procedures, triggers, views, and defaults.

13If you have partitioned tables, update partition statistics.

14Run dbcc again on all databases to verify that they run cleanly.

Recovering from a failed upgrade

During the upgrade process, the log may get full due to the catalog changes that are made. If so, log in to the new server using isql, and issue:

isql> dump tran dbname with no_log

This frees the log space, and allow the upgrade process to continue.

In some cases, the pre-upgrade space estimations might be insufficient for the data copy phase of upgrade. In this case, you may get an error that there is insufficient space in the system segment for the upgrade. The upgrade process hangs, waiting for space to be provided. You can log in to the new server using isql, and use alter database to increase the size of the database.

Sybase 15.0.2 manual Recovering from a failed upgrade

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.
