OOW19: WebLogic News

During the Oracle Open World 2019 were some announcements regarding Oracle WebLogic Server.

The last year announced WebLogic Server 19c for Q1/2019 disappeared ...
There will be no WebLogic Server 13 Release ...

But there will be:

  • The WebLogic Server 12.2.1.4 Release will be the Final Maintenance Release for 12. (more...)

  • Oracle Sign up: more problems

    I thought, i was successful, but:

    I received a mail with the following content:

    "We have re-authorized a new, specific amount on the credit/debit card used during the sign up process."

    and

    "To verify the account you have created, please confirm the specific amount re-authorized."


    My problem: there is not any "re-authorized amount" on my banking account. I do not know, what is "re-authorized"?
    Is this: this amount is charged on my (more...)

    but i only got:
    I think the problem is, that there i a manual review step on Oracle's side which i have not passed for now:

    Oracle Cloud: Sign up failed… [3] & solved

    Finally (see my attempts here and here) i was able to sign up to Oracle cloud.
    What did the trick?

    I got help from Oracle support:
    So i used my gmail address and this worked:

    and then:

    Let's see how this cloud will work compared to Azure and AWS

    Fishbowl Solutions Transforms Parent & Guardian Communications with a One-Stop Mobile Application using Oracle Mobile Cloud Service Development

    One of the largest school districts in the nation ― with hundreds of thousands of students enrolled in kindergarten through 12th grade at over 1,000 schools and over 200 public charter schools ― was struggling to keep parents and guardians informed about their students’ grades, lunch balances, activities, and general district and school news.

    Problem

    The District’s boundaries extend across more than 700 square miles and include a major U.S. city as well as (more...)

    Oracle Cloud: Sign up failed… [2]

    After my failed registration to Oracle cloud, i got very fast an email from Oracle support with the following requirements:
    So i tried once again with a firefox "private" window - but this failed again.
    Next idea was to use a completely new installed browser: so i tried with a fresh google-chrome.
    But the error still remained:
    Let's hope Oracle support has another thing which will put me onto Oracle cloud.

    Multi-Nodes Redis Cluster With Docker

    Read this article on my new blog As part of my on-boarding/training at RedisLabs I continue to play with the product, and I have decided today to install a local 3 nodes cluster of Redis Enterprise Server (RS); and show how easy is to move from a single node/shard database to a multi nodes highly available one. Once your cluster is up & running, you will kill some containers to see how

    Getting Started With Redis Streams & Java

    Read this article on my new blog As you may have seen, I have joined Redis Labs a month ago; one of the first task as a new hire is to learn more about Redis. So I learned, and I am still learning. This is when I discovered Redis Streams. I am a big fan of streaming-based applications so it is natural that I start with a small blog post explaining how to use Redis Streams and Java. (more...)

    Enterprise Manager 13.3 – After Upgrade to DB Plugin 13.3.2: Missing ‘Top Activities’ Page and Empty Graphs when using ‘Performance Hub’

    oops - long title ... sorry for that

    Starting with DB Plugin 13.3.2.0, oracle has kicked out the flash plugin and replaced that with JET (JavaScript Extension Toolkit). As a consequence, 'Top Activity' page is not available anymore and is replaced by 'Performance Hub' respectively 'Ash Analytics' and 'SQL Monitoring'. 

    That's the good news ... the not that good news is: Both pages will show empty graphs in case the monitored (more...)

    Ubuntu Linux: Change from Legacy boot to UEFI boot after installation

    This weekend i did an installation of Linux on a laptop where already a windows 10 was installed.
    Because laptop did not recognize my linux boot usb-stick i changed from UEFI to legacy mode and the installation went through without any problem.

    At the end grub was in place but the windows installation was not listed. This is, because windows does not support booting.

    The problem: If i switch back to UEFI the linux installation (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...)

    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...)

    A Different Approach


    Sharing knowledge is what the ACE Program is all about, blogs, white papers, books and presentations. 


    ACEs having been speaking at education facilities for many years, in UKOUG we encouraged this through our "Next Generation' initiative and many ACEs actually work part time in Education sharing their knowledge.

    The way we consume knowledge is also changing, meet-ups and webcasts are now the norm and video is the way we learn everything from changing a (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...)

    Linux: Configuring hosts per ssh in parallel: pssh

    If you have to set up some hosts in a way, that a number of commands has to be executed on each node, than you should consider PSSH:

    The installation is straight forward:
