Similar to Oracle Multitenant Database 2.0 - Improvements in Oracle Database 12c Release 2 (20)
Before version 9i of the Oracle database, more and more Oracle components stored their tables in the SYSTEM tablespace. This lead to a high space consumption in this important tablespace. In Oracle database 10g introduced the SYSAUX tablespace and moved everything which is not part of the data dictionary from the SYSTEM tablespace to SYSAUX. Since then, more and more database components populate the SYSAUX tablespace and it keeps growing ... - and if the DBA is not careful, the tablespace SYSAUX tablespace can become really huge
The presentation shows how to analyze and reduce the occupancy of the SYSAUX tablespace and how to avoid it in advance by suitable settings.

It discusses what OraChk checks for, how to install and run it, and how to configure options like running checks automatically as a daemon. It also demonstrates how to add custom checks and view results through the Collection Manager GUI. Administrators can use OraChk to audit their Oracle configurations and compare environments.
The document discusses Trace File Analyzer (TFA) and the Oracle Support Tools Bundle. TFA collects trace and log files from Oracle databases and clusters to help diagnose issues. It was originally released in 2013 as a standalone tool, but is now part of the Autonomous Health Framework (AHF). AHF provides a centralized way to collect, analyze, and manage diagnostic data across an enterprise Oracle environment. The document provides an overview of TFA's capabilities, how to install and configure AHF/TFA, and demonstrates how to use TFA to collect diagnostic data from a single node cluster.
The document provides information on how to reduce the size of the SYSAUX tablespace in an Oracle database. It discusses which database components occupy space in SYSAUX, including top offenders like SM/AWR and SM/OPTSTAT. It then describes various methods to cleanup the SYSAUX tablespace such as reorganizing tables and indexes, moving components to other tablespaces using provided procedures, and reducing retention periods for components like AWR and advisors to delete old data. Proper sizing of the SYSAUX tablespace is also discussed.
The document discusses factors to consider when deciding whether to migrate away from an Oracle database platform. It outlines some common reasons companies consider migrating, such as high costs of Oracle licenses and support. However, it also notes that migrating involves costs for migration, training, and operating on a new platform. The document advises evaluating database products and scenarios carefully before deciding to migrate or stay with the existing Oracle platform. It concludes that not every application needs Oracle and alternatives exist, but simplicity should be prioritized over unnecessary changes.
This document provides an overview and summary of Oracle Database privilege analysis. It introduces the concept of privilege analysis and the principle of least privilege. It describes the Oracle package DBMS_PRIVILEGE_CAPTURE that is used to define capture policies and run analyses. It outlines the workflow including defining policies, running applications to capture privileges, generating results, and evaluating the results. The document also discusses some considerations and examples of using privilege analysis to adopt a least privilege model for database users and applications.
Trivadis is an IT consulting firm with over 650 employees across 15 locations. The document provides an overview of Trivadis' mission, expertise, products, key figures, and introduces Markus Flechtner, a principal consultant specializing in Oracle database performance tuning. It then outlines an agenda for a performance issues checklist, covering how to specify problems, performance analysis methodology, and the tools Statspack and Tuning Pack.
This document provides a checklist for troubleshooting database connection issues. It begins with basic checks like ensuring the database and listener are running. It then covers checking the network infrastructure and Oracle Net configuration. This includes verifying the listener configuration, domain names, services registration, timeouts and tnsnames.ora. The document recommends using tools like tnsping and SQL*Plus to test connections. It also suggests testing connectivity using Oracle Instant Client to rule out application configuration issues.
The document provides information about Trivadis, an IT consulting company, and discusses database upgrade and migration. It begins with an overview of Trivadis' mission to reduce complexity for customers through technological expertise. The next sections cover Trivadis' key figures, the experience of consultant Markus Flechtner, and an agenda for discussing database upgrade and migration methods and steps. The checklist then reviews choosing the right upgrade/migration methods, considerations for using DataPump, preparing clients and databases, creating a project plan, testing, and post-upgrade checks.
Die Datenbank ist nicht immer Schuld - Gründe warum Datenbank-Migration schei...Markus Flechtner
Datenbank-Migrationen und -Upgrades scheitern oft nicht an Fehlern in der Datenbank-Software oder in den jeweiligen Prozeduren. Oft sind es (vemeintlich) kleinere Dinge wie veraltete Clients oder fehlende Netzwerk-Anpassungen, die eine Migration zum Scheitern bringen. Der Vortrag bringt Beispiele und Tipps zur Vermeidung.

UI5con 2024 - Bring Your Own Design SystemPeter Muessig
How do you combine the OpenUI5/SAPUI5 programming model with a design system that makes its controls available as Web Components? Since OpenUI5/SAPUI5 1.120, the framework supports the integration of any Web Components. This makes it possible, for example, to natively embed own Web Components of your design system which are created with Stencil. The integration embeds the Web Components in a way that they can be used naturally in XMLViews, like with standard UI5 controls, and can be bound with data binding. Learn how you can also make use of the Web Components base class in OpenUI5/SAPUI5 to also integrate your Web Components and get inspired by the solution to generate a custom UI5 library providing the Web Components control wrappers for the native ones.

When it is all about ERP solutions, companies typically meet their needs with common ERP solutions like SAP, Oracle, and Microsoft Dynamics. These big players have demonstrated that ERP systems can be either simple or highly comprehensive. This remains true today, but there are new factors to consider, including a promising new contender in the market that’s Odoo. This blog compares Odoo ERP with traditional ERP systems and explains why many companies now see Odoo ERP as the best choice.
What are ERP Systems?
An ERP, or Enterprise Resource Planning, system provides your company with valuable information to help you make better decisions and boost your ROI. You should choose an ERP system based on your company’s specific needs. For instance, if you run a manufacturing or retail business, you will need an ERP system that efficiently manages inventory. A consulting firm, on the other hand, would benefit from an ERP system that enhances daily operations. Similarly, eCommerce stores would select an ERP system tailored to their needs.
Because different businesses have different requirements, ERP system functionalities can vary. Among the various ERP systems available, Odoo ERP is considered one of the best in the ERp market with more than 12 million global users today.
Odoo is an open-source ERP system initially designed for small to medium-sized businesses but now suitable for a wide range of companies. Odoo offers a scalable and configurable point-of-sale management solution and allows you to create customised modules for specific industries. Odoo is gaining more popularity because it is built in a way that allows easy customisation, has a user-friendly interface, and is affordable. Here, you will cover the main differences and get to know why Odoo is gaining attention despite the many other ERP systems available in the market.

Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

21.03.17 Multitenant 2.0 - Oracle Database 12c Release 24
5. 21.03.17 Multitenant 2.0 - Oracle Database 12c Release 25
Technology on its own won't help you.
You need to know how to use it properly.
6. Agenda
Multitenant 2.0 - Oracle Database 12c Release 26 21.03.17
1. Looking back: Multitenant in Oracle Database 12c Release 1
2. General new features
3. New Features for PDB provisioning
4. PDB Lockdown Profiles
5. Resource Management
6. Application Containers
7. Summary
8. Oracle Multitenant in 12c R1
Multitenant 2.0 - Oracle Database 12c Release 28 21.03.17
The multitenant architecture (“Container Database Architecture”) introduced in
Oracle Database 12c Release 1 enables an Oracle database to work as a container
database (CDB)
A new database architecture designed for:
– consolidation/database virtualization
– fast and easy provisioning
– separation of administrative duties
– rapid movement of user data (unplug/plug)
Pluggable databases (PDBs) are compatible with traditional non-CDB (same behaviour
from the application point of view)
several restrictions in Oracle Database 12c Release 1
10. Available database architectures in Oracle 12c

General New Features
12. Local Undo
Multitenant 2.0 - Oracle Database 12c Release 212 21.03.17
In 12c R1 the Undo tablespace was a common resource in the CDB$ROOT container
In 12c R2 the Undo tablespace can be defined on PDB level („LOCAL UNDO“)
This setting has to be defined during the creation of the CDB
– But can be changed afterwards
Local Undo is recommended
– Some new features require local Undo
CREATE DATABASE
..
ENABLE PLUGGABLE DATABASE .. LOCAL UNDO ON .. PDB01 [RW]
Application Tablespaces

PDB$SEED
[RO]
13. Flashback of Pluggable Databases
Multitenant 2.0 - Oracle Database 12c Release 213 21.03.17
With local Undo, flashback of a PDB is straightforward:
Without local Undo, Oracle creates an auxiliary instance when flashing back a PDB
– Default auxiliary destination is the Fast Recovery Area
– Can be changed in the „FLASHBACK“-command
ALTER SESSION SET CONTAINER=PDB1;
CREATE RESTORE POINT PDB_FB_DEMO;
..
ALTER SESSION SET CONTAINER=CDB$ROOT;
ALTER PLUGGABLE DATABASE PDB1 CLOSE;
FLASHBACK PLUGGABLE DATABASE PDB1 TO RESTORE POINT PDB_FB_DEMO;
ALTER PLUGGABLE DATABASE PDB1 OPEN RESETLOGS;
14. Unplug a PDB into PDB archive file
Multitenant 2.0 - Oracle Database 12c Release 214 21.03.17
PDB Archive File
– Contains manifest + datafiles
– Extension must be .pdb
It‘s a ZIP file with misleading suffix
ALTER PLUGGABLE DATABASE PDB02 CLOSE;
ALTER PLUGGABLE DATABASE PDB02 UNPLUG INTO '/tmp/pdb02.pdb';
DROP PLUGGABLE DATABASE PDB02 including datafiles;
..
CREATE PLUGGABLE DATABASE PDB02 USING '/tmp/pdb02.pdb'
FILE_NAME_CONVERT=('/tmp','/u01/oradata/TVDCDB1/PDB02');
ALTER PLUGGABLE DATABASE PDB02 open;
15. Pluggable Databases with different Character Sets
Multitenant 2.0 - Oracle Database 12c Release 215 21.03.17
If the CDB character set is AL32UTF8, PDBs with a different character set can be
plugged in
If the CDB character set is not AL32UTF8, all PDBs must use the character set of
CDB$ROOT
It‘s not possible to create a new PDB with a different character set
PDB01 [RW]
AL32UTF8
CDB$ROOT (AL32UTF8)
PDB$SEED
AL32UTF8
PDB02 [RW]

16. „Small things“ (1)
Multitenant 2.0 - Oracle Database 12c Release 216 21.03.17
Maximum number of PDBs raised from 252 to 4096 (Exadata + Oracle Cloud only)
Number of PDBSs can be limited
– new parameter MAX_PDBS
– Hitting the limit results in „ORA-65010: maximum number of pluggable databases
created“
Feature availability
– Heatmap and ILM are supported
– Sharding is not supported L
Database Options
– DBCA supports creating a CDB with a subset of features
Important for Single-Tenant!
17. „Small things“ (2)
Multitenant 2.0 - Oracle Database 12c Release 217 21.03.17
Parallel Creation of PDBs
Automatic Workload Repository (AWR) on PDB level
CREATE PLUGGABLE DATABASE .. PARALLEL [DOP];

18. Multitenant 2.0 - Oracle Database 12c Release 218 21.03.17
New Features for PDB provisioning
19. Hot Cloning
Multitenant 2.0 - Oracle Database 12c Release 219 21.03.17
When cloning a PDB the source PDB does not
need to be READONLY anymore
– CDB must be in Archivelog-mode
– Cloning uses Media Recovery
In Noarchivelog-mode, READONLY mode
for source PDB is still required
Possible with 12.1.0.2, too – but neither
documented nor supported

20. PDB refresh (1)
Multitenant 2.0 - Oracle Database 12c Release 220 21.03.17
Idea:
refresh a PDB in regular intervals
Use case: Use cloned PDB as source
for further PDB cloning
Cloned PDB can only be opened in read
only-mode
Refresh can be done manually or
automatically
Source and target PDB must be
in different CDBs
Target PDB must be closed for refresh

28. PDB Lockdown Profiles (3)
Multitenant 2.0 - Oracle Database 12c Release 228 21.03.17
Activate a profile
– New static parameter on PDB level: PDB_LOCKDOWN
Tipp: Always disable „ALTER SYSTEM“ via Lockdown Profile
alter session set container=PDB1;
ALTER SYSTEM SET PDB_LOCKDOWN = demo_lckdprf SCOPE = SPFILE;
ALTER PLUGGABLE DATABASE PDB1 CLOSE;
ALTER PLUGGABLE DATABASE PDB1 OPEN;
29. PDB Lockdown Profiles (4)
Multitenant 2.0 - Oracle Database 12c Release 229 21.03.17
What happens in the PDB?
SQL> alter system flush buffer_cache;
Error at line 1:
ORA-01031: insufficient privileges
SQL> alter system flush shared_pool;
System altered.
SQL> CREATE TABLE .. PARTITION BY ..
ERROR at line 1:
ORA-00439: feature not enabled: Partitioning
31. Resource Management for Pluggable Databases
