It comprises of several sub-components such as Snapshot, Memory Based Planner, Loader Workers, etc. These modules are primarily written in C/C++, Java, Pro*C, PL/SQL. This system is supported on Linux, Solaris, AIX, Windows and HPUX.

Responsibilities include design, development, testing and implementation of enhancements and new features, bug fixing, performance tuning, high level support, interaction with various teams whose data feeds into ASCP. Performance was tuned using SQL Hints for the DMLs and Valgrind for memory leaks.

Enterprise Manager Grid Control

This project involves the design and development of a number of enhancements and bug fixes for the Enterprise Manager Tool in Java and Perl. It was implemented on Oracle Enterprise Linux platforms using Oracle 11g database. Worked on automation of Agent Patching and Provisioning Tools.
