Oracle RU Update Assistant

It is sometimes difficult to find the right Metalink note and then the correct RU update.

Now there is the interactive Oracle Assistant DOC ID 2118136.2 which is very helpful and offers quick help.

Just try it out and be amazed. It is very helpful

 

Unexpected Behavior


"Expect everything, I always say, and the unexpected never happens."
― Norton Juster, The Phantom Tollbooth

DBMS_LOGMNR is a great tool for finding information about what’s going on in an Oracle database. If it’s written to the redo logs DBMS_LOGMNR can find it. But sometimes it can find too much information, especially when assumptions are made regarding table ownership. Application code is often tested with ‘pristine’ database configurations, where ‘one table, one owner’ is (more...)

Handling Socket connectivity with API Gateway

At the time of writing the Oracle API Platform doesn’t support the use of Socket connections for handling API data flows. Whilst the API Platform does provide an SDK as we’ve described in other blogs and our book it doesn’t allow the extension of how connectivity is managed.

The use of API Gateways and socket based connectivity is something that can engender a fair bit of debate – on the one hand, when a client (more...)

It’s A Date?


"You often learn more by being wrong for the right reasons
than right for the wrong reasons." 
― Norton Juster, The Phantom Tollbooth

Dates. The term can conjur fear in the strongest hearts, mainly due to problems that arise when date formats are taken for granted. Not every Oracle database is configured with the ‘default’ Oracle-supplied date format, DD-MON-RR. Since this setting can be changed at both the database level and the session level (more...)

Costs in Multi-Cloud

Over the last couple of years we have seen growing references to multi-cloud. That is to say, people are recognizing that organisations, particularly larger ones are ending up with cloud services for many different vendors. This at-least in part has come from where departments within an organization can by meaningful resources within their local budgets.

Whilst there is a competitive benefit of the recent partnership agreement between Microsoft and Oracle given the market margin AWS (more...)

Why do I have an Ace logo on my website?

For the observant, you’ll have noticed that I have a logo on left side of my site saying Oracle Ace. Periodically I get asked what is it, what does it mean, and for those who are less involved in the Oracle community probably don’t know what it means.

What

Most developers will probably have encountered the idea of Java Champions or perhaps Microsoft MVPs (Most Valued Professional). All of these badges, and other large (more...)

London Oracle Developer Meetup – OIC Patterns and more

This Meetup was put together quickly as it presented an opportunity to align with other events happening in the Oracle offices. Despite the relatively short notice we a turn out that really made great use of our speaker – Sid Joshi who walked through the Enterprise Level patterns supported by Oracle’s Integration Cloud (OIC) including a demo showing how PaaS4SaaS worked using Service Cloud and OIC making use of VBCS and integration (formerly ICS) parts (more...)

Managing API Gateway Costs with Oracle API Platform

The Oracle API Platform adopted an intelligent pricing model by basing costs on API call volumes and Logical gateway node groupings per hour. In our book about the API Platform (more here). We suggested that a good logical grouping would be to reflect the development, test, preproduction and production model. This makes it nice and easy to use gateway based routing to different environments without needing to change the API policy configuration as you (more...)

Popping Up on the Net and more

It’s been a quiet month for this blog, but we’ve been pretty busy with a raft of other activities…

  • recent article on our sister site – oracle-integration.cloud on  RPA.
  • We also appear in an interview with K21 Academy here.
  • 4186btedcpl._sx403_bo1204203200_Reviewing a new book on Enterprise API Management for Packt which we would very highly recommend if you want to understand the more Enterprise perspectives of adopting APIs, particularly if you’re considering APIs as a (more...)

“Just One More…”


"So each one of you agrees to disagree with whatever the other
one agrees with, but if you both disagree with the same thing,
aren't you really in agreement?" 
― Norton Juster, The Phantom Tollbooth

Partitions can make DBA life easier; they allow faster access to data through partition pruning and they allow for easier archiving and removal of old data. There’s not much that can go wrong with partitions [ominous silence]… until you (more...)

“Hear ye, hear ye!”


"Have you ever heard the wonderful silence just before the dawn? Or the quiet
and calm just as a storm ends? Or perhaps you know the silence when you haven't
the answer to a question you've been asked, or the hush of a country road at
night, or the expectant pause of a room full of people when someone is just
about to speak, or, most beautiful of all, the moment after the door closes

API Security

I’ve started to subscribe to the APISecurity.io news letter. The news letter includes the analysis of recent API based security breaches along with other useful API related news. Some of the details of the breaches make for interesting reading and provide some good examples of what not to do. It is rather surprising how regularly the lack of the application of good practises is, including:

  • Checking the payload is valid to the definition,
  • Checking (more...)

Integrating API Management with the rest of your Development Pipeline

Oracle API Management keeps API policy configuration and management internalized for a number of reasons including security (after all you don’t want your security rules for APIs out in the open).  The Platform does provide simple versioning.  But you need to able to link the policies to the back end implementations – so the policy configuration is aligned to what is implemented. For example you don’t want the policy to accept parameters that (more...)

API Platform – Plans & Subscriptions

When it comes to Plans and Subscriptions on the Oracle API Platform we have a very flexible set of relationships. When it comes to checking the relationships to ensure a configuration is correct and that the impact of changing a plan or subscription is clear.  I end up having to draw a little diagram, which always leaves me second guessing myself about which way the linkages are. So I created a quick aide memoir, (more...)

Union Station


"Since you got here by not thinking, it seems reasonable to expect that,
in order to get out, you must start thinking."
-- Norton Juster, The Phantom Tollbooth

Combining two data sets can go in several directions and, in the absence of common columns, conventional wisdom would point to using UNION to generate such sets and for many applications this is a suitable solution. If, however, these unions are the ‘table’ for another query, (more...)

Alphabet Soup


"Ali zar u buci nema i dobrih zvukova?" 
-- Norton Juster, The Phantom Tollbooth

Disaster recovery is on the mind of every Oracle DBA, the goal being that there is never a need to use it. Setting optimism aside, many enerprises run regular DR tests to ensure that business can continue as usual should a catastrophic event affect the data center. Before the advent of Oracle Managed Files a ‘proper’ DR onfiguration included generating (more...)

Everything As Code – Article for PTK

PTK 2019-04-30.pngPTK (Pass The Knowledge) is the new name for the Independent UK Oracle User Group‘s journal, previously known as Oracle Scene.  Yesterday saw the 1st release under its new name, and I’m proud to say that I have an article included called Everything as Code.

Not only that,  it is great to see the journal includes the appearance of one of my Oracle Team colleagues at CapgeminiAmy Simpson-Grange (more...)

Threadbare


"Expect everything, I always say, and the unexpected never happens."
-- Norton Juster, The Phantom Tollbooth

Oracle has, since version 11.2, required standby redo logs to be configured for a Data Guard installation, even though in 11.2 the default log apply process relied on archived redo logs, not the standby logs. That changed in 12.1 and the default became what Oracle labelled “Real Time Apply”; the choice to use archived redo (more...)

Making A List


"Expect everything, I always say, and the unexpected never happens."
-- Norton Juster, The Phantom Tollbooth

In-lists can be a convenient way to search for multiple values in a single select statement. They can be hard-coded or can operate on the results of a subquery, and in the first case the reported limitation is 1000 elements, and that is correct for single-valued elements. If the elements are multi-valued that limit changes, which may be (more...)
