Upcoming Webinar, “WebCenter Search that Works!” highlights Oracle WebCenter integration with Mindbreeze InSpire

Earlier this month, Fishbowl announced the release of our Oracle WebCenter Content Connector for Mindbreeze InSpire. The Connector enables the Mindbreeze enterprise search appliance to securely index and serve content stored in WebCenter Content. The Connector also allows customers to leverage the Mindbreeze Search App Designer to embed modern search apps directly in WebCenter Content.

As the quantity of unstructured information continues to expand, content management success depends on the ability to find data in a growing information flood. Without search that works, managed content becomes lost content. By integrating Oracle WebCenter with Mindbreeze InSpire you can improve information discovery, increase user adoption, and encourage content reuse through better search.

In our upcoming webinar, we will provide an overview of the Mindbreeze InSpire enterprise search appliance and our integrations with both WebCenter Content and Portal. We’ll cover what a typical implementation looks like and why customers are making the switch. We’ll also discuss the migration path off deprecated Oracle Secure Enterprise Search and Google Search Appliance technologies, and options for adding other sources like SharePoint and network shares.

We hope you’ll join us.

Imanis Data

DBMS2 - 9 hours 55 min ago

I talked recently with the folks at Imanis Data. For starters:

  • The point of Imanis is to make copies of your databases, for purposes such as backup/restore, test/analysis, or compliance-driven archiving. (That’s in declining order of current customer activity.) Another use is migration via restoring to a different cluster than the one that created the data in the first place.
  • The data can come from NoSQL database managers, from Hadoop, or from Vertica. (Again, that’s in declining order.)
  • As you might imagine, Imanis makes incremental backups; the only full backup is the first one you do for that database.
  • “Imanis” is a new name; the previous name was “Talena”.

Also:

  • Imanis has ~35 subscription customers, a significant majority of which are in the Fortune 1000.
  • Customer industries, in roughly declining order, include:
    • Financial services other than insurance.
    • Insurance.
    • Retail.
    • “Technology”.
  • ~40% of Imanis customers are in the public cloud.
  • Imanis is focused on the North American market at this time.
  • Imanis has ~45 employees.
  • The Imanis product just hit Version 3.

Imanis correctly observes that there are multiple reasons you might want to recover from backup, including:

  • General disaster/system failure.
  • Bug in an application that writes data.
  • Malicious acts, including encryption-by-ransomware.

Imanis uses the phrase “point-in-time backup” to emphasize its flexibility in letting you choose your favorite time-version of your rolling backup.

Imanis also correctly draws the inference that the right backup strategy is some version of:

  • Make backups very frequently. This boils down to “Do a great job of making incremental backups (and restoring from them when necessary). This is where Imanis has spent the bulk of its technical effort to date.
  • In case recovery is needed, identify that last clean (or provably/confidently clean) version of the database and restore from that. The identification part boils down to letting the backup databases be queried directly. That’s largely a roadmap item.
    • Imanis has recently added the capability to build its own functionality querying the backup database.
    • JDBC/whatever general access is still in the future.

Note: When Imanis backups offer direct query access, the possibility will of course exist to use the backup data for general query processing. But while that kind of capability sounds great in theory, I’m not aware of it being a big deal (on technology stacks that already offer it) in practice.

The most technically notable other use cases Imanis mentioned are probably:

  • Data science dataset generation. Imanis lets you generate a partial copy of the database for analytic or test purposes.
    • You can project, select or sample your data, which suggests use of the current query capabilities.
    • There’s an API to let you mask Personally Identifiable Information by writing your own data transformations.
  • Archiving/tiering/ILM (Information Lifecycle Management). Imanis lets you divide data according to its hotness.

Imanis views its competition as:

  • Native utilities of the data stores.
  • Hand-coded scripts.
  • Datos.io, principally in the Cassandra market (so far).

Beyond those, the obvious comparison to Imanis is Delphix. I haven’t spoken with Delphix for a few years, but I believe that key differences between Delphix and Imanis start:

  • Delphix is focused on widely-installed RDBMS such as Oracle.
  • Delphix actually tries to have different production logical copies of your database run off of the same physical copy. Imanis, in contrast, offers technology to help you copy your databases quickly and effectively, but the copies you actually use will indeed be separate from each other.

Imanis software runs on its own cluster, based on hacked Hadoop. A lot of the hacking seems to related to a metadata store, which supports things like:

  • Understanding which (incrementally backed up) blocks need to be pulled together to make a specific copy of the database.
  • Putting data in different places for ILM/tiering.

Another piece of Imanis tech is machine-learning-based anomaly detection.

  • As incrementally backed-up blocks arrive, Imanis flags anomalous ones and states a reason for them.
  • A flag is given a reason.
  • You can denounce the flag as a false alert, and hopefully similar flags won’t be raised in the future.

The technology for this seems rather basic:

  • Random forests for the flagging.
  • No drilldown w/in the Imanis system for follow-up.

But in general concept this is something a lot more systems should be doing.

Most of the rest of Imanis’ tech story is straightforward — support various alternatives for computing platforms, offer the usual security choices, etc. One exception that was new to me was the use of erasure codes, which seem to be a generalization of the concept of parity bits. Allegedly, when used in a storage context these have the near-magical property of offering 4X replication safety with only a 1.5X expansion of data volume. I won’t claim to have understood the subject well enough to see how that could make sense, or what tradeoffs it would entail.

An Important Change Is Coming for Application Express 5.2 (if you use the Mobile User Interface)

Joel Kallman - 10 hours 17 min ago
An important change is coming in Oracle Application Express 5.2.  The mobile user interface (based upon jQuery Mobile) will be deprecated.  The deprecation announcement will be included with the forthcoming Application Express 5.1.3 patch set release.

What this means for you
  • If you have applications developed with the mobile user interface based upon jQuery Mobile, they will continue to function in a supported fashion in Application Express 5.1.x.  Premier Support of Oracle Application Express 5.1.x continues until December 2021.
  • New mobile applications should be created using the Desktop User Interface and Universal Theme (Theme 42) and not the Mobile User Interface & jQuery Mobile-based theme (Theme 51).
  • Existing mobile applications should be migrated to the Universal Theme if you want to run them on Oracle Application Express 5.2 and later.

Why is this happening?The last stable version of the jQuery Mobile library was released on October 31, 2014, and it only provides support for jQuery versions 1.8 through 1.11, and jQuery 2.1.  Patches are no longer provided for these versions of jQuery.  Application Express 5.2 will ship with jQuery 3.2 (necessary for us to adopt the latest Oracle JET libraries).  jQuery Mobile will not function properly with jQuery 3.2.

While we will make every effort to devise a way to include the necessary libraries for jQuery-mobile based applications in Application Express 5.2, that may not solve all problems entirely, especially when we try to include the data visualizations via Oracle JET, which have different dependencies.  We do truly strive to ensure backward compatibility of APEX applications across upgrades.  It's of paramount importance to us, and we spend a lot of time and energy ensuring that stability, operation, look and feel remain constant across APEX version upgrades.  But in this specific case, there doesn't appear to be a practical solution.  We're in a box.

There has been some recent activity in a new version of jQuery Mobile, namely 1.5alpha.  But given the fact that there was a very long hiatus on jQuery Mobile for an extended period of time, and it's unlikely that jQuery Mobile 1.5 will be stable enough by the time Application Express 5.2 is released, we collectively decided to announce depreciation of the Mobile User Interface based upon jQuery Mobile.  We literally spent months researching and contemplating this dilemma.  It's unfortunate.  The positive angle, though, is that we're in complete control of the Universal Theme and should not encounter similar issues with Universal Theme-based applications in the future.

Oracle Instant Client 12.2 now has SQL*Loader and Data Pump

Christopher Jones - Mon, 2017-08-21 19:17

Oracle Database 12c iconThis is a guest post by Jim Stenoish, Senior Director of Software Development, whose products include all tools used for the high speed movement, transformation, and loading of data and metadata for Oracle Database.

Oracle Instant Client 12.2 now includes SQL*Loader as well as the Data Pump command line utilities expdp and impdp, and the traditional Export/Import utilities exp and imp. Previously, these tools were only available with a 'full' client installation, or in a database installation. Being in Instant Client allows users to access these tools with a smaller footprint on disk and with a much quicker install than for a full client. The OTN license is also more convenient for many users.

Now these tools are part of Instant Client, it's easy to load data from a file on a system the doesn't already have Oracle software installed.

Installing the Tools

You can install the tools by unzipping the Oracle Instant Client 'Basic' (or 'Basic Light') package and the 'Tools' package to the same location. See the Instant Client home page for links to download for each platform.

Follow the platform-specific instructions given on the download page. For example, on Linux set LD_LIBRARY_PATH and PATH to the Instant Client directory. On Windows set PATH to the Instant Client directory and also install the Microsoft Visual Studio 2013 Redistributable.

Using the Tools

SQL*Loader allows you to load data from files, such as comma-separated value files (CSV), into the tables.

The expdp and impdp utility allows you to move metadata and data between Oracle databases. The expdp utility unload metadata and data from the database into Data Pump files on the database server. The impdp utility recreates metadata defined in a Data Pump file and loads table data stored in the files on the database server. It also provides a way to extract metadata and data over a DB Link (no files involved) from one database to another database.

Documentation and examples for the tools are in the Database Utilities manual.

If you have questions about SQL*Load or Data Pump you can ask them on OTN.
