CI/CD for Oracle Database & APEX Developers CI/CD for Oracle Database & APEX Developers RMOUG Virtual Training Days 2021 Brian Spendolini Product Manager Oracle Database Development Tools @btspendo btspendo https://blogs.oracle.com What is CI/CD? 2 Copyright © 2020, Oracle and/or its affiliates What is CI/CD and Why do we need it? CI/CD is continuous integration, continuous delivery, and continuous deployment • Introduces automation into all stages of app/database development • Helps developers work on the same app and merge their code changes back to a shared branch frequently • Development changes are automatically tested on push/commits and merges Why? • Consistency/Repeatability • Accountability • Security • Standardization • Find Issues Faster/Better Code/Quality Releases • More Frequent Releases 3 Copyright © 2020, Oracle and/or its affiliates CI/CD with the database and APEX? Traditionality this has been hard. Why? • APEX/DB bucks the trend of isolated development environments • Dev instances can be expensive • Licensing issues • DB/APEX changes are different from traditional files/code seen with DevOPs and CI/CD processes • Metadata driven • Versioning or lack there of • Rollback issues • Very manual process and a lot of individual accountability • DB change tracking • APEX change tracking • Isn't DevOps for those new-fangled development languages only? 4 Copyright © 2020, Oracle and/or its affiliates CI/CD with the database and APEX? We can fix it? Yes, we can! Centralized code repository no more big zips or wiki pages with attachments Individual code branches Individual development environments Easy change tracking creating scripts is not fun Embrace the cloud Autonomous Database uses per-second billing ADB’s can cost less than $35 a day 5 Copyright © 2020, Oracle and/or its affiliates CI/CD with the database and APEX? What tools do I need? • Git/code repository • SQLcl/Liquibase • VS Code/SQL Developer • utPLSQL • Terraform • OCI account (free/paid) • Jenkins 6 Copyright © 2020, Oracle and/or its affiliates SQLcl and Liquibase What’s SQLcl? Oracle SQLcl (SQL Developer Command Line) is a Java-based command-line interface for Oracle Database. Using SQLcl, you can execute SQL and PL/SQL statements interactively or as as a batch file. SQLcl provides inline editing, statement completion, command recall, and also supports existing SQL*Plus scripts. What’s Liquibase? Liquibase is an open-source database-independent library for tracking, managing and applying database schema changes. How do they work together? The Liquibase feature in SQLcl enables you to execute commands to generate a changelog for a single object or for a full schema (changeset and changelogs). 7 Copyright © 2020, Oracle and/or its affiliates Terraform and OCI • Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. • Think Infrastructure as code • Full set of APIs/Resources for OCI via Terraform • https://registry.terraform.io/providers/hashicorp/oci/latest/docs • Create and Destroy OCI resources quickly and consistently • Similar to OCI CLI resource "oci_database_autonomous_database" "new_autonomous_database" { #Required compartment_id = var.compartment_ocid cpu_core_count = "1" data_storage_size_in_tbs = "1" db_name = "TESTDB${random_string.db_name.result}" admin_password = random_string.password.result db_workload = "OLTP" display_name = "TESTDB${random_string.db_name.result}" } 8 Copyright © 2020, Oracle and/or its affiliates Sample Environment What’s a sample environment look like for CI/CD with the Autonomous database and OCI?

  • Automated Testing of Database Schema Migrations
    DEGREE PROJECT IN COMPUTER SCIENCE AND ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2019 Automated Testing of Database Schema Migrations PETER JONSSON KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Automated Testing of Database Schema Migrations PETER JONSSON Master in Computer Science Date: June 28, 2019 Supervisor: Johan Gustavsson Examiner: Elena Troubitsyna School of Electrical Engineering and Computer Science Host company: The Swedish Police Authority Swedish title: Automatiserad testning av databasschemaförändringar iii Abstract Modern applications use databases, and the majority of them are relational databases, which use schemas to impose data integrity constraints. As appli- cations change, so do their databases. Database schemas are changed using migrations. Certain conditions can result in migrations failing in production environments, leading to a broken database state and testing can be problem- atic without accessing production data which can be sensitive. Two migration validation methods were proposed and implemented to au- tomatically reject invalid migrations that are not compatible with the database state. The methods were based on, and compared to, a default method that used Liquibase to structure and perform migrations. The assertion method used knowledge of what a valid state would look like to generate pre-conditions from assertions to verify that the database’s state matched expectations and that the migrations were compatible with a database’s state prior to migra- tion. The schema method, used a copy of the production database’s schema to perform migrations on an empty database in order to test the compatibility of the old and new schemas. 108 test cases consisting of a migration and a database state were used to test all methods.

  • Database Refactoring with Liquibase
    Database Refactoring with Liquibase Michael Le Feuvre, OnBelay Consulting Agenda • What is Database refactoring • Introducing Liquibase • Liquibase example • Questions OnBelay Consulting 2 Database Refactoring Evolutionary change OnBelay Consulting 3 Traditional approach • Traditional approach to changing the database schema. • Make an appointment to see the DBA. • Plead that you want to add a column to an existing table • DBA considers your request • Decides to grant it but first must update the ER diagram in a horribly expensive Database Architecture and Design tool that maintains a logical data model. The model is then rendered in to a physical model. Great for wall charts. • DBA generates or hand-codes the database changes into SQL scripts. • DBA then updates each database directly that requires the changes. OnBelay Consulting 4 Consequences of traditional approach • Because the overhead in the traditional process is so onerous, many organizations required that database design be done up front so that the database was “ready” for programmers to use. • Database artifacts may not be in source control. • If database objects are in source control they aren’t necessarily in the same repository as the application source code. application code changes and database changes are not committed together in the same commit. • The above process is entirely antithetical to an Agile development process and since the database requirements must be known in advance of starting development • Most organizations manage database changes somewhere between traditional and database refactoring. OnBelay Consulting 5 Database refactoring • Based on the concept of refactoring popularized by Martin Fowler: • described as a “refactoring as a small change to your source code that improves its design without changing its semantics.” (Refactoring, Martin, James, 1999) • Evolutionary approaches to database maintenance have been discussed since the 2000’s.
