Update from a Previous Version of Event Stream Processor

Sybase Event Stream Processor maintains backwards compatibility with previous versions. If desired, you can continue running the previous version after you have installed your update.

When you update Event Stream Processor:

Projects written for the previous version will run on the current version and produce the same results without having to be recompiled. Use the Studio interface to open or import existing projects.
With the following exceptions, adapters and client programs written with the previous SDK are compatible with the current release without having to be recompiled with the latest SDK:
- Java client code compiled against the 5.0 Java SDK must run using JRE 7 under Event Stream Processor version 5.1.
- For the Custom Adapter Framework, the return type for the following functions has changed from int to int64_t: getNumberOfGoodRows, getNumberOfBadRows, getTotalRowsProcessed. If your application written in 5.0 uses any of these functions, rewrite the application for 5.1.
- For security reasons, Event Stream Processor no longer supports the no authentication option.
- Kerberos authentication is now ticket-based. Update existing adapters and clients to use Kerberos ticket-based authentication and setter methods.
Deployment scripts work the same way in the current version as they did in the previous version without any changes.

Installation Location
When installing the current version of Event Stream Processor, you can either install to an entirely new directory, or you can install to the same directory as your previous version (or to the same directory as any installed Sybase product).
Clearing the PATH Variable
When you update your installation, ensure that the previous setting for the PATH system variable is cleaned up.
Updating your License
