About me


I am Sushanth. Full name is Sushanth Bobby Lloyds.

I am a Db2 DBA on z/OS platform with over 11 Years of work-experience living in Chennai, India. I specialise in reviewing Complex SQLs, accesspaths & setting up lots of Queue Replication in Db2 used to setup SQL Replication as well and i am well versed with Rexx scripts to automate repeatative tedious tasks.

I am insightful, creative, self-driven, result oriented IT professional with notable success in research, planning, analysis and implementation of solutions and have hands-on experience in all stages of project life cycle development. Besides my specialization in DB2, my current passion is in Big Data & Cloud and I am doing a lot of self-studies, courses to understand how it works and to improve my knowledge on the subject as well. Other than that, I am pretty cool to work with.

# Work Experience

Royal Bank of Scotland(RBS) / Natwest Group | Sept 2011 - Present


  • Infrastructure Analyst - Db2 DBA | Sept 2011 - Dec 2016
  • Technical Lead - Db2 DBA | Dec 2016 - Present

Work Activities

  • Migrated entire Relationship Manager Platform from SQL Replication to Q Replication ( which includes 583 tables source tables ) without any issues/incidents.
  • Review 200+ programs for access path changes for every release(Quarterly) in RMP Banking Platform
  • Setup and implement SQL Replication & Q Replication for large number of tables for each release
  • Running EZ-DB2 Traces for analyzing online application performance
  • Identified lots of worst performing queries in Development itself and suggested developers to modify them.
  • Supported the bank during the critical RBS MAJOR RED ALERT in 2012( one of the world’s biggest technical failures )
  • Db2 Driver installations

Tools/Utilities which I created to improve work & performance

  1. Advanced Explain Tool( REXX + ISPF Panels )

    Purpose : To reduce the time taken to review lots of DB2 packages in development environment. Main functionality is to pick up the latest packages from the specified environment and generate Access Path Report. Two types of reports are available,

    • Basic Explain Report – Generates AP report with data from PLAN_TABLE & DSN_STATEMNT_TABLE
    • Advanced Explain Report – Generates AP report with data from 5 Explain Tables with more details.

    Other than AP report this tool also retrieves statistics information from DB2 catalogs on all the objects used by a particular package and this will reduce analysis time.

  2. Queue Replication SQL Generator(REXX + ISPF Panels)

    Purpose : Main purpose of the tool is to generate all necessary SQL’s to setup Q Replication including the jobs needed for implementation during migration from SQL Replication to Q Replication. The Tool takes care of all the standard naming conventions and thereby reducing lots of laborious manual work when ASNCLP is used.

    Other Features of the tool include,

    • Generating test SQLs to check whether replication works.
    • Performs Sanity checks, compares the SOURCE with CCD & AUDIT tables to see if the structure matches.

JavaUsed for scrapping websites and processing data in mySQL
FirebaseUsing firebase realtime database from 2017 and stash uses firebase as backend storage.
PythonStarted using it since 2019 for Udacity Data engineering
