The PCI is a generic interface internal to Adaptive Server; it is installed by default when you install or upgrade Adaptive Server. The PCI Bridge, a component internal to the PCI, performs the actual work between Adaptive Server and the JVM plug-in.
The PCI Bridge provides:
Native thread (process) management
Memory management
Synchronization (lock, condition, and event) management
Data access service support
Configuration management
On-demand function dispatching with automatic plug-in loading
Signal and exception handling
Platform runtime support
Dynamic instrumentation facility
Error message channeling to the Adaptive Server error log
For most scenarios, the default PCI Bridge configuration is appropriate and sufficient. If necessary, and with the advice of Sybase Technical Support, you can use the sp_pciconfig system stored procedure to modify the PCI configuration. sp_pciconfig includes parameters that allow you to list, report, enable, or disable the directives and arguments in sybpcidb. See “Changing configuration values in a running server”.
