Tuning and monitoring the effectiveness of OBIEE 11g is often neglected today, but is very important once OBIEE 11g therapy is deployed. Not providing clear and complex information is too much for the success of your BI project, it also needs to be shared quickly. Understanding how OBIEE works and how it relates to Fusion Components (FMW) software middleware is very important in tuning your system to get the best performance out of your wonderful existing hardware.dovaniya. In this article, I want to walk you through the OBIEE gestures and customization process, covering the key points you should ideally check out in your current project. Then we’ll see how you can track your practice on a daily basis with the available performance tools, allowing you to identify common performance issues and take action to fix them. The content of this article is by no means a blueprint with all the answers, as such an issue is beyond the scope of a blog post, although I hope this information will be sufficient for those interested in regards, good to start improving and start following them. OBIEE situations. why it’s slow is common Usually, performance issues in an OBIEE environment are first noticed because users complain that application reports are a bit slow, too slow, or at least slower than before. In this situation, as a system administrator, you should not guess what might be causing this. Your experience will be very helpful in identifying the fastest most likely the causes of the problem, but it is important to test your empirical assumptions. There are almost always four main areas that can be the main culprits. Layer
- General layer
- Hardware layer
- Network layer
Why is Obiee so slow?
Why is it running slowly? A1: You can see from nqquery. Store in the BI server how long your current SQL takes in the database so you don’t have to use it manually. Perhaps withThe BI server must successfully perform some additional work on the knowledge before it is returned to the user.
Imagine you are a system administrator and therefore have no idea what the problem might be in this particular case. In this procedure, you must follow a formal procedure to check all areas where you may find a cause and correct them as well. This scenario is different from the scenario where you don’t have specific user complaints, but as an action you need to implement, constantly strive to improve your system’s performance over an already existing baseline. In this case, we would all be talking about improving the system. More on that later in the thread. So let’s start by looking at one of the four areas to see where the most likely places something could go wrong.
Improve Performance
How to improve performance in OBIEE 11g?
Respectively one with parallel request.separation.Appropriate indexing. Data typesuse them as good as they come, especially when it comes to joins to columns.Use materialized view controls for prepackaged aggregations of your underlying evidence.Statistics.
OBIEE Level And Databases
If youThe sha environment is stable, which means you don’t often encounter these performance issues, it’s possible that the cause of this issue is within the limits of OBIEE. There may be some operations that should be done in the same order as below.
1. Reproduce the first issue
You will need to reproduce the issue to confirm the script reports performance is correct. It’s very important to be able to reproduce this non-working time, as well as generate the report at different times of the day, so that you can reject (or confirm) that the components that this report refers to have some kind of bottleneck at a particular time. It’s also important to reproduce a scenario with a terrific user who reported, and those who suffer, with other users. You can achieve this with the OBIEE impersonation feature. Here we filters to see the marketplace identifications (row-level security) applied to this person, which can result in negative queries being generated. These two simple tests will give you a better idea of ​​when and by whom.No problem.
2.Check the main client request
Once you confirm that there is a problem, the next step is to get the actual physical query that the report passes to the target databases. In this case, we’re talking about a dashboard page where you can run scan after scan, although it’s almost always visually obvious which scan is taking the most time, allowing you to prioritize your efforts. To get physical queries, you need to check the logs (nqquery.log) if your system is not configured with LOGLEVEL, at least one or two. If it’s not a lawsuit and you’re in a hurry, you can get a logical doubt in the report tab on the top answer editor, and then run the query through the version control-specific “Create Logical Query”. Here you can determine which level of logging you want to use for that particular topic (and don’t forget to disable the use of the BI view cache!). When you have a query, physical if it will have an Access database, you willYou should start your usual query methods, tweaks like explanatory plan checking, Tk*Prof, misplaced indexes, etc… < /p>
3. Check your RPD model
How do I monitor obiee performance?
There are many ways to monitor OBIEE performance, but they usually use log file merging and the built-in monitoring tools available in Enterprise Manager, such as the Performance Monitor summary. To access this tool, you need to log in to Enterprise Manager and right-click on your bi_serverX WebLogic for domain partition.
