The OWB 184.108.40.206 Cumulative Patch 3 has just been released, the bug/patch number is 16568042. This cumulative patch wraps a number of bugs from customers using the OWB 11gr2 release. See the patch readme for details.
To install ODI 11g into an Oracle 12c pluggable database, one way is to connect using a TNS string to the pluggable database service that is executing. For example when I installed my master repository, I used a JDBC URL such as;
I used the above (more...)
This expert greatly simplifies getting up and running with XML in ODI, well I think so anyway. It (more...)
The connect/disconnect call outs are a useful mechanism for executing code at the start and end of connections - you can write SQL, PLSQL and all sorts through this callout. The code is useful for example for recording your own additional audit information. The code is executed using the execute (more...)
You can quickly configure your SCD metadata on ODI datastores using this helper script here. Executing this script from the UI you can specify a driver file to quickly annotate your datastores with slowly changing metadata flags on the columns. To illustrate, let's use the dimension from an earlier posting (more...)
ODI can easily process RSS data from the filesystem or web...the ODI XML technology has a driver whose file specification includes support for filesystem, URL and ftp. So processing RSS feeds is very simple. The reverse engineer can also generate a DTD based on the XML, so you don't even need a DTD or XML schema for the input stream. Converting JSON to XML and reversing is a very simple way to reverse a schema for information such as JSON, you can then enrich the model in ODI. In the URL below which I defined for an XML dataserver, (more...)
Yesterday I posted a user function for compressing/decompressing files using parallel processes in ODI. The same code you can pick up and use from an OWB process flow. Invoking the java function from within a Java activity from within the flow.
The JAR used in the example below can be downloaded here, from the process flow OWB invokes the main method within the ZipFile class for example - passing the parameters to the function for the input, output directories and also the number of threads. The parameters are passed as a string in OWB, each parameter is wrapped in ?, (more...)
Here's a couple of user functions for compressing and decompressing files in parallel, you can control the degree of parallelism, it will compress/decompress all files in one directory and write into another. The number of parallel processes can be configured on invocation. I posted some time back about how ODI User Functions are really useful, this is a great example. What I have here is a couple of user functions you can call in an ODI Procedure or an ODI KM for example and the functions have 3 arguments; the input directory of files to compress/decompress, the output directory where (more...)
Here's how you can run the latest version of an ODI scenario from a load plan, package or SDK without explicitly defining the scenario version. Although the UI infers you pick a specific version of the scenario code to execute, if you type in -1 for the version the latest version of the scenario code is executed.
Not sure how many customers are aware of that but a handy tip. I'm confident not many use it in the UI as its kind of tricky to setup. If you just type the scenario name and -1 its OK that works fine, (more...)
Oracle provides a secure and convenient functionality for securing data in your datawarehouse, tables can be designed in OWB utilizing the Transparent Data Encryption capability. This is done by configuring specific columns in a table to use encryption.
When users insert data, the Oracle database transparently encrypts it and stores it in the column. Similarly, when users select the column, the database automatically decrypts it. Since all this is done transparently without any change the application code, the feature has an appropriate name: Transparent Data Encryption.
Encryption requires users to apply an encryption algorithm and an encryption key to (more...)
