Security of Oracle EBS - How I can Protect my System (UKOUG APPS 18 edition)Andrejs Prokopjevs
Nowadays having a proper security configuration is a huge challenge, especially looking at the global hacks and personal data leak incidents that happened in IT a while back. Oracle EBS is not perfect and has lots of vulnerabilities covered by Oracle almost every quarter. A very small percent of Apps DBAs know all the features and options available, and usually, do not go over firewall/reverse proxy layer.
This presentation is going to cover an overview and recommendations of options and security features that are available and can be used out-of-the-box, and some of the non-trivial configurations that can help to keep your Oracle EBS system protected, per our experience.
This is the slide deck of the Zend webinar "Scalable High-Availability Session Storage with ZSCM".
Almost all PHP applications today use sessions, and many of them use sessions for storing business critical data. With the Session Clustering feature of Zend Server Cluster Manager, you can store and share sessions across a cluster of PHP servers, in a linearly scalable, easy to manage and most important highly-available manner.

Everyone knows installing PHP on IBM i is easy. Just download the save file and run the RSTLICPGM command. But not everyone knows what that RSTLICPGM does. What is it putting on the machine? Where is it putting it? How does it all work together? In this session, we'll take a look at the IFS directories added by the Zend Server installer, to see what's in them. We'll see where PHP and PHP extensions, Apache and FastCGI configurations, log files, and more are kept. We'll also talk about how these new file objects interact with existing prerequisite software on the IBM i to present dynamic pages to the web. This session is for PHP developers and administrators interested in learning how PHP fits in with the unique operating environment of IBM i.
URP? Excuse You! The Three Kafka Metrics You Need to KnowTodd Palino
What do you really know about how to monitor a Kafka cluster for problems? Is your most reliable monitoring your users telling you there’s something broken? Are you capturing more metrics than the actual data being produced? Sure, we all know how to monitor disk and network, but when it comes to the state of the brokers, many of us are still unsure of which metrics we should be watching, and what their patterns mean for the state of the cluster. Kafka has hundreds of measurements, from the high-level numbers that are often meaningless to the per-partition metrics that stack up by the thousands as our data grows.
We will thoroughly explore three key monitoring concepts in the broker, that will leave you an expert in identifying problems with the least amount of pain:
Under-replicated Partitions: The mother of all metrics
Request Latencies: Why your users complain
Thread pool utilization: How could 80% be a problem?
We will also discuss the necessity of availability monitoring and how to use it to get a true picture of what your users see, before they come beating down your door!

PHP Apps on the Move - Migrating from In-House to Cloud RightScale
RightScale Conference NYC 2012 -- PHP Apps on the Move - Migrating from In-House to Cloud
Kent Mitchell - Sr. Director, Product Management, Zend
It’s a common problem: How to move your PHP system to the cloud without completely overhauling your app. Most existing systems and applications were not designed for the level of elasticity the cloud brings. But many of those apps can still take advantage of all that the cloud offers - while requiring very few modifications.
In this session, we will discuss how one customer leveraged the off-the-shelf capabilities of RightScale and Zend to migrate from a fixed, non-scalable traditional architecture to an elastic, high-availability cloud architecture. Join us for a deeper look at this auto-scaling PaaS solution specifically designed to make it easier for you to deploy and manage cloud-based, highly available PHP server clusters.
This is the slide deck of the "Performance Tuning PHP on IBM i" given by Mike Pavlak and Alan Seiden in Feb 2012. They discuss some of the more fundamental areas that reveal performance bottlenecks. They explore hardware, software and configuration options that will help your PHP applications fly. The discussion reviews features for both Zend Server and Zend Server CE.

In this last years a lot of high traffic web sites have been built in PHP. One of the main problem to design a distributed PHP architecture is how to share session data between multiple servers. In this presentation we showed the most used solutions to scale a PHP application along multiple servers. We presented different solutions to share session data using open source solutions (nfs, databases, memcached, redis, etc). Moreover we talk about Zend Server Cluster Manager, an enterprise ready Web Application Server for running and managing an HA Cluster of PHP servers.
PHP is the top platform for building and modernizing IBM i applications. In this webinar, Erwin discusses how features of the application server can be leveraged to streamline the development process as well as fast-tracking the management of the PHP environment.
Enhancing scalability with intelligent cachingEric Ritchie
As applications grow in popularity, or after successful marketing efforts, increased traffic can cause problems for application servers. Caching is a relatively inexpensive and quick solution to the problem however, if implemented badly, can easily become a new bottleneck or even a point of failure. This session will demonstrate how to design a caching layer that will enhance scalability rather than fetter it.
When thinking about moving your PHP application to PaaS (if it's bluemix, heroku or others), you should take into account several architectural differences that will affect your application. This presentation is a good place to start your migration plan to PaaS.

The Fastest Way to Redis on Pivotal Cloud FoundryVMware Tanzu
What do developers choose when they need a fast performing datastore with a flexible data model? Hands-down, they choose Redis.
But, waiting for a Redis instance to be set up is not a favorite activity for many developers. This is why on-demand services for Redis have become popular. Developers can start building their applications with Redis right away. There is no fiddling around with installing, configuring, and operating the service.
Redis for Pivotal Cloud Foundry offers dedicated and pre-provisioned service plans for Cloud Foundry developers that work in any cloud. These plans are tailored for typical patterns such as application caching and providing an in-memory datastore. These cover the most common requirements for developers creating net new applications or who are replatforming existing Redis applications.
We'd like to invite you to a webinar discussing different ways to use Redis in cloud-native applications. We'll cover:
- Use cases and requirements for developers
- Alternative ways to access and manage Redis in the cloud
- Features and roadmap of Redis for Pivotal Cloud Foundry
- Quick demo
Presenters: Greg Chase, Director of Products, Pivotal and Craig Olrich, Platform Architect, Pivotal

Presenter – Mike Pavlak - (44 min) February 15, 2012
This presentation reviews these steps, scenarios and more:
• What is this database going to be used for – a reporting server or data warehouse, or as an operational database supporting an application?
• Which resources should I spend the budget on to ensure optimal database performance – bigger servers, more CPUs/cores, disks, or more memory?
• What are my backup requirements? If I ever need to restore, how far back do I need to go and what will that mean to the business?
• How will I handle any hot fixes, such as security patches? What downtime can be afforded and what processes need to be in place to apply critical or maintenance updates?
• What are my replication and failover requirements and what should I do for my high availability configuration?

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

ZF – remember opcode caching?
Desing in modular way
Application performance optimization – question to always ask yourself: 1- what am I gaining? 2- would it be cheaper to throw hardware at the problem? 3- how do I prove it. -> if gaining 2X by optimizing but cost is 3X what it would cost to buy a server and gain 1.5 or 1.8 times, decision is relatively easy. Cost v/s gain.
ORM is going to return results in any way it knows -> up to you to optimize
Trade-offs of performance v/s code readability and “pretty” architecture. Cf. Martin fowler on Enterprise architecture design patterns.
What I mean here is that you need to start thinking about what the app is going to be used for at the early planning stage, because that will define certain design decisions you make.
If low traffic, I can send 100-200 queries to db per page, they’re really fast. I can therefore use a readable code because at the code level I’m just using my most basic objects to perform CRUD. But if high traffic app, then I need to start thinking, do I really want 100-200 queries to the DB per page, or should I, instead, try to optimize this by designing special objects that perform CRUD specific to this context?
A Zend Consultant’s secret weapon: Code tracing. -> DEMO
Know the hardware:
If I know the HW I’m writing for, if for example I’m writing a read/write heavy app, and I know that disks are particularly slow, I’ll emphathize caching.
That’s valid advice for caching too by the way. If a piece of code takes 3 seconds to execute (some kind of recursive menu build), and it takes a few minutes to add caching to it, if the menu does not change often, why bother spending hours rewriting?... Better to just add caching.
Performance optimization in general is an art, not a science. Like good application design.
EXPLAIN is your friend. Using the power of an in application query profiler combined with EXPLAIN, you can tune your SQL statements to the dot.
Demo: ZFA app (wiki) with the use of Zend_Db_Profiler
Add indexes where needed, if a query is too intensive on the server, try to take some of the logic out of the query, split it into multiple subqueries and do some heavy lifting in PHP instead of the database.
If you are given time, try to optimize before caching. I know I said before that if caching is easier, then go with that, but as with everything, if it’s too easy, you cache and cache, and before you knmow it, well you’re running memcached on a 40 Gb RAM server that holds a copy of your databse and you’ve written a whole architecture/layer to keep your cache in sync with DB.
It’s all about balance, and that comes with experience.
Explain vmstat output
Important because in an ideal world, 3 limits would be hit together. But if you know what you app’s usage patterns are, then you know where to optimize, and you know what the specs to your next server are!
