Basic IT Services If you have a small business and just need help keeping things operating, we can help. For most small business, it’s just not cost-effective to have your own internal IT staff. In that case, you’ll most likely have to rely on an outside company to provide IT support. It’s important that you work with a company that is both committed to you as a customer, and is capable of learning your systems and processes. Otherwise everytime you need help you’ll waste time and resources “starting over”. Our approach is to become a partner with our customers. We negotiate a flexible contract that allows us to be committed to you, and to invest time and energy into learning and documenting your systems. It’s the next-best-thing to having your own internal IT staff. In fact – it might even be better! Website Development For example, we built this one. Whether you’re looking for something fairly simple (like this site), or whether you need a full-blown eCommerce site, we can help. We have designers and developers that can help you get the look and feel that you want, and the functionality you need in order to be effective. Software Development There is commercial off-the-shelf software available for almost any need. However, if you have a unique business, or a unique workflow, or the software for your industry is simply bloated and ugly and hard to use, then custom software development might be your answer. Most of our recent software development work has been around improving business processes by building new data collection and analysis tools. However, we have experience in inventory control systems, eCommerce, customer resource management systems and more. Data Analysis Odds are your business is generating tons of data. Your website generates user statistics. Your marketing campaigns generate both financial and sales data. Your manufacturing systems generate data. Your quality management systems generate data. If you can leverage the data from these systems, you’ll be able to make better business decisions. If you can integrate the data from these systems and get a company-wide view of your data, it can transform your business. Project Management It’s pretty intuitive that projects that are properly managed go better. In fact, do some research into the biggest reasons why projects fail. What you’ll find is that poor project management is one of the top reasons. Why should you consider bringing in an outsourced project manager? 1. If you’re working on a complicated, multi-vendor project, it can be incredibly useful to have somebody outside of those vendors who is responsible for looking at the big picture and managing the project as a whole. If you don‘t have the expertise in both the subject matter and in project management, then maybe we should chat. 2. If you’re working on an internal project but you don’t really have an in-house resource with the organizational sway or skillset required to managed the project through to completion, an outsourced resource can help. There’s something powerful about bringing in a resource and giving them the authority to get things done. You don’t have staff in-fighting over “why did he get to be in charge”. The authority is usually pretty quickly accepted and you can move on with the project. 3. Things are crazy busy, timelines are tight, budgets are tight – these can all sound like good reasons not to bring in a project manager. Think about it this way – when resources are limited, can you afford to waste precious resources by having a poorly-managed project?

Oracle also mentions the occurrence of this error if you use DB Console or Enterprise Manager to monitor your databases and the emagent will try to connect to the target database Analysis Brainstorm: Gather Hypotheses: What might have caused the problem? Is there a firewall on the laptop that blocks outgoing connections? Some stays idle.

Additionally we should use IP addresses in the file or if names are used, that they are defined in the hosts file so we can rule out any DNS issues. We see the client try three times before changing the source TCP port by adding one to the number and trying unsuccessfully three more times, before the application gives up and After sometime the firewall drops them and I get those operation timed out problems. I believe that this "problem" is caused by an incorrect default for some of the parameters.

Errata? The reason the messages are written to the alert log is related to the use of the new 11g Automatic Diagnostic Repository (ADR) feature being enabled by default. In this particular case an opened case with Oracle resulted in finger pointing. Please consider your business requirement for allowing connections to remain or appear 'idle' before implementing these suggestions.

Here you may find a particular client, set of clients or particular applications that are improperly disconnecting causing the timeout errors to be raised and recorder in the database alert log.

This issue can arise during a long running query or when using JDBC Thin connection pooling. I did some checking with documentation but couldn’t find any explanation. Taking a closer look and comparing the two packet captures, we see that the only difference between them is the source port. Every time the client picked an arbitrary source TCP port to communicate with the server, and it happened to fall within the range of (4660-4678), it would be rejected by "iptables"
