Two techniques are described: 1) creating a new cluster or 2) upgrading the existing cluster. The speaker also discusses moving the Automatic Storage Management (ASM) configuration to an extended RAC across multiple storage locations. Q&A is offered at the end to discuss any other questions.
Oracle Flex ASM - What’s New and Best Practices by Jim WilliamsMarkus Michalewicz
Oracle Open World (OOW) 2014 Presentation by Jim Williams (Oracle ASM Product Manager) on Oracle Flex ASM - What's New and Best Practices. The presentation provides an overview of enhancements (What's New) in Oracle ASM 12c, especially with respect to Oracle Flex ASM, and provides best practices which can be applied in any environment (Flex or Standard ASM). This presentation has also more background information for some of the configuration recommendations that I made in my "Oracle RAC (12.1.0.2) Operational Best Practices" presentation.
The more components a system has, the more challenging its maintenance becomes. Oracle Exadata marries storage with computation through a fast, reliable network, and patching all of these seems daunting. Many companies seem to struggle with it, with some even avoiding it altogether by keeping it “pending.” This session presents tested, applied, and working tips to make the Oracle Exadata patching experience smooth as silk, like vacationing in Hawaii.
Exadata has been around since 2008 and the software features are being enhanced each release. This Presentation talks about the 12.1.x.x series of Software updates and some of the things you can now do with Exadata

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.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Upgrading 10g cluster to 11gR2 grid
Moving ASM to extended RAC
Questions
Erez@valinor.co.il
41. Upgrading 10g cluster to 11gR2 GI
• Technique 1 :
Creating a new cluster.
Erez@valinor.co.il
42. Technique 1 : Creating a new cluster
Step 1 : If your db is 10.2.0.1 or below so first
upgrade it to 10.2.0.4
Step 2 : Taking (of course) a full backup of the db
(rman or storage snapshot).
The following steps are if you are using
the same machine:
Step 3 : Backup spfile (if not in asm)/init.ora
Step 4 : Take notes of the current services
(prefered nodes,TAF policies,etc…)
Erez@valinor.co.il
43. Technique 1 : Creating a new cluster
Step 5 : Uninstall rdbms software (both ASM and
DB if separated) and cluster software.
Step 6 : Uninstall clusterware and cleanup the
machine (use metalink:239998.1)
Step 7 : Install 11gR2 Grid Infrastructure
Step 8 : Install 10.2.0.1 rdbms software and
upgrade it to 10.2.0.4 (or the version of
your DB).
Erez@valinor.co.il
44. Technique 1 : Creating a new cluster
Step 9 : Copy the backed up spfile/init.ora to it‟s new
place.
Step 10 : Add the DB to the new cluster by using
“srvctl add database” and add then add
instances by using “srvctl add instance”
Step 11 : Add services by using srvctl add service.
Erez@valinor.co.il
45. Technique 1 : Creating a new cluster
If you choose to do it on a new machine
you have 3 possibilities:
• After shutdown the DB, unmap LUNs from old
machines and map them to the new machine
(has to be same OS).
If using linux run the command oracleasm
scandisks as root user and then oracleasm
listdisks. In other case you can use the following
command “kfod disks=all dscvgroup=TRUE”
Erez@valinor.co.il
46. Technique 1 : Creating a new cluster
• Export the data and then import it into a newly
created database.
• Using Transportable database to move it to a new
machine. In this case the DB can me moved
between platforms (look at oracle documentation
for limitations).
Erez@valinor.co.il
47. Upgrading 10g cluster to 11gR2 GI
• Technique 2 :
Upgrading the existing cluster.
Erez@valinor.co.il
48. Technique 2 :
Upgrading the existing cluster
This technique is well documented in oracle but I‟ve
choose to build a new one for the following
reasons/issues:
• When beginning the upgrade we had only 1 votedisk.
After running rootUpgrade.sh on the first node this
node changed/upgraded the only votedisk available
and the second node upgrade (of course) failed.
Erez@valinor.co.il
49. Technique 2 :
Upgrading the existing cluster
• After a second retry, which succeeded, at the final
step we‟ve made a restart to the cluster but it failed to
start because for some unknown reason the
interconnect and public interface configuration were
changed in such a way the cluster was not able to
start anymore and it was unable to get to a state were
the reconfiguration was possible (using oifcfg ).
Erez@valinor.co.il
51. Moving ASM to Extended RAC
Extended ASM is actually a diskgroup in normal or high redundancy in
which each Failure Group is on a separate storage machines
in different locations.
Erez@valinor.co.il
52. Moving ASM to Extended RAC
I used the following main steps to migrate our 11gR2 asm
to extended RAC:
• Step 1 : Map new volumes from both storage
machines to all the cluster nodes. The same number
and size of volume should be use in both storages.
• Step 2 :Create a new Diskgroup/s with normal
redundancy when each failgroup is on a different
storage.
Erez@valinor.co.il
53. Moving ASM to Extended RAC
• Step 2a: Create a normal redundancy diskgroup with
at least 3 disks for the votedisks and OCR.
• Step 3 Move votedisks to new DG (“crsctl replace
votedisk +<NEW DG NAME>”)
• Step 4 Move ocr disks (ocrconfig)
• Step 5 Move controlfiles to new DG‟s
Erez@valinor.co.il
54. Moving ASM to extended RAC
• Step 6 When DB is in mount state copy datafiles to
new DG by using the command: “backup as copy
database format +<NEW DATA DG”
• Step 7 After succsessfully competion of the copy
perform the following to update control file with the
copied datafiles :”switch database to copy” and then
“alter database open”
Erez@valinor.co.il
55. Moving ASM to extended RAC
• Step 8 : Create a new temp TBS or add a new file to
the current one and then delete the old file from that
temp TBS(alter database tempfile „path to file‟ drop;)
• DONE.
Erez@valinor.co.il
