Set connection retry frequency on DataSource in WebLogic 12c.

I have encountered several times in WebLogic 12c that when the ConnectionPool of a DataSource in WebLogic could not be initialized because due to a connection error or invalid username or password, the server could not be started.

I can't remember having encounterd this problem in 11g, and this week I struggled with it with one of my customers. The perception of the DBA there was that in 11g the server did start up, but (more...)

Start and stop a WebLogic (SOA/OSB) Domain

So let's start the day with a blog. In the past few months I created scripts to install FMW products and build a WebLogic domain for it. For most of my findings I did a blog already:

Create WebLogic users for ServiceBus 12c

Last week I wrote a blog about how to create WebLogic users for ServiceBus 12c. However, I did not now how to assign a particular Application Specific Role to the weblogic user, for particular ServiceBus privileges. I did find out what particular Roles there were (see the blog). But how to assign them I found out just today.

So here it is:

Reset your Datasources

In most SOASuite and Oracle ServiceBus projects the Database Adapter is used. And often it is used to invoke PL/Sql functions and procedures. Actually, it's my favorite interaction method with the database, since the re-entrancy of the database adapter wizard is best there. To do a re-entrant update of a select or DML operation when for instance a column is added, is simply put often quite problematic.

But the thing is with Pl/Sql that when (more...)

Oracle as the new IBM — has a long decline started?

When I find myself making the same observation fairly frequently, that’s a good impetus to write a post based on it. And so this post is based on the thought that there are many analogies between:

  • Oracle and the Oracle DBMS.
  • IBM and the IBM mainframe.

And when you look at things that way, Oracle seems to be swimming against the tide.

Drilling down, there are basically three things that can seriously threaten Oracle’s market (more...)

Readings in Database Systems

Mike Stonebraker and Larry Ellison have numerous things in common. If nothing else:

  • They’re both titanic figures in the database industry.
  • They both gave me testimonials on the home page of my business website.
  • They both have been known to use the present tense when the future tense would be more accurate. :)

I mention the latter because there’s a new edition of Readings in Database Systems, aka the Red Book, available online, courtesy of (more...)

Transitioning to the cloud(s)

There’s a lot of talk these days about transitioning to the cloud, by IT customers and vendors alike. Of course, I have thoughts on the subject, some of which are below.

1. The economies of scale of not running your own data centers are real. That’s the kind of non-core activity almost all enterprises should outsource. Of course, those considerations taken alone argue equally for true cloud, co-location or SaaS (Software as a Service).

Issues in enterprise application software

1. I think the next decade or so will see much more change in enterprise applications than the last one. Why? Because the unresolved issues are piling up, and something has to give. I intend this post to be a starting point for a lot of interesting discussions ahead.

2. The more technical issues I’m thinking of include:

  • How will app vendors handle analytics?
  • How will app vendors handle machine-generated data?
  • How will app vendors (more...)

Couchbase 4.0 and related subjects

I last wrote about Couchbase in November, 2012, around the time of Couchbase 2.0. One of the many new features I mentioned then was secondary indexing. Ravi Mayuram just checked in to tell me about Couchbase 4.0. One of the important new features he mentioned was what I think he said was Couchbase’s “first version” of secondary indexing. Obviously, I’m confused.
