OID Install in Oracle Enterprise Linux (OEL) 5 - Shared Libraries Error

amit.gupta — Sun, 01 Nov 2009 14:45:44 +0000

When installing 10g OID on OEL5, if you run into the following error, you can run the below commands to address the issue:

Error:

OPMN HTTP process fails to start.  When you look in the log file, it says:
/Apache/Apache/bin/httpd: error while loading shared libraries: libdb.so.2: cannot open shared object file:  No such file or directory

To fix, run the following commands:

# ln -s /usr/lib/libgdbm.so.2.0.0 /usr/lib/libdb.so.2
# chmod 755 /usr/lib/libgdbm.so.2.0.0
# chmod 755 /usr/lib/libdb.so.2

When I did a quick search online, I found some keyboard shortcuts for Visual Studio 2008 that didn’t work for me, so thought I would get a post going.

BPEL Not Good For Rapid Changes

ashok.aggarwal — Wed, 16 Sep 2009 15:12:50 +0000

I am excited about BPEL’s proliferation. But for some organizations (specifically, IT shops), BPEL is being used in areas it is simple not well-suited. For example, some places where IT has gotten ahead of the business, it is used as a process modeling tool. True, BPEL “represents” a process, it is my opinion that proper business modeling tools be used prior to orchestration being defined in BPEL.

Another scenario I continue to find is that people are using BPEL for just about every piece of logic that goes into a business process being executed. The fact is, BPEL does very well at integrating with other services where complex — and more importantly, “fast-changing” — logic is executed. So, my advise is to not throw away every other tool in the belt in the face of BPEL. Fast-changing decisions are better handled outside of BPEL, especially as you consider the deployment process for BPEL, and most especially if you have long-running processes. Business rules engines, databases, and external services that perform specific logic/functions should continue to be leveraged in these cases. I’d be interested in hearing from others who are concerned about this challenge or maybe have already faced it.

Google Apps Reporting API - Not quite this easy with Exchange

ashok.aggarwal — Fri, 04 Sep 2009 14:44:19 +0000

I have been somewhat enamored by Google Apps and its potential. Many enterprises have been happy with Exchange for mail, calendaring, contacts, and more. I have been one of those people. However, I have found Google Apps to be getting better and better for use in the enterprise and I will not be surprised to see it begin to take significantly larger chunk of market share from Microsoft over time.

Features are added quickly both through the web-based application (with zero-footprint) and through client applications like Google Sync. Google also makes some things so easy that I have no choice but to wonder what that simplicity is worth to me.

I recently decided to pop into the Google Apps Reporting API. Since we have a few new customers on Google Apps, I wanted to try to get a sense of what the usage and uptake was.

I first realized that there were a variety of choices — .NET, PHP, Java, Python, etc. — for accessing the API programmatically. I was able to quickly get a .NET example working, but the instructions and were geared to a client-based example…and of course, I wanted to display the reports on the web. So, I began to work with the PHP examples next. While I was fiddling with the PHP example, I continued my browsing on the web and began planning to incorporate the Google Charts API.

But before I wasted much more time with development, as minimal as it may have been, I found the Reporting Visualization API along with easy-to-follow documentation on how to display charts into iGoogle without any code. Moreover, the API can handle a query as input, allowing me minor customizations which is all I really needed to start.

I can see that disk usage has gone up over the last few days with a big jump on Wednesday…someone must have been uploading their old emails. I don’t find the report capabilities to be very powerful just yet, but it is easy to see that Google can add functionality quickly and make this an incredibly powerful tool.

Modular Flex Development - Multiple SWFs

ashwin.suresh — Tue, 01 Sep 2009 16:04:09 +0000

I have been tasked with coming up with a modularized approach for logically separating out an extensive Flex application I am developing. I see Flex 3.4 might have some features I can take advantage of.

Google Custom Search Engine (CSE)

ashok.aggarwal — Mon, 24 Aug 2009 12:45:19 +0000

Effectively and efficiently searching content will continue to be a challenge on the internet. I feel Google has made a fantastic contribution to the web community with Google Custom Search Engine (perhaps also known as Site Search). What’s better? I think they have found a way to improve their own index through this tool — an unadvertised win-win and genius move on Google’s part.

I was able to quickly use CSE to create a search engine for my own use with my favorite sites and also create a search across a few of the sites I work on regularly. Of course, I need to make sure all my pages are indexed by Google in order for my site search to work the way I need. That’s right, I take on an even more active and important role in my site’s indexing. I already had a vested interest, but that interest has just gone up even further for a site where I use CSE. At some point, I envision removing our site search capabilities (perhaps even on mandsconsulting.com) and replacing them with Google’s CSE.

You will see a news release here in coming days identifying a site that takes advantage of Google CSE.

OBIEE for the iPhone

ashok.aggarwal — Wed, 12 Aug 2009 06:57:42 +0000

We recently had a customer request help with configuring OBIEE for use on both PCs and mobile devices (specifically, the iPhone). Of course, this is possible, but Oracle does not have a clearly documented approach. You might think that a separate server is required to accomplish this. However, the fact is that you can actually use a single server to deliver OBIEE reports for both PCs and the iPhone.
