The excitement of solving mysteries makes me bad at math
In my last post, I failed to notice that a HugePages_Total of 4645, while satisfyingly greater than zero, is definitely not 8196, the desired and expected value I had configured. Upon reflection, the reason was pretty obvious: the OS will only allocate contiguous blocks of memory [...]
After two months of cheerfully monitoring your E-Business Suite instances, Grid Control declares that most of the Apps tier targets have ‘Unknown’ status. What just happened? Sunspots? Evil gnomes? E-Business Suite snubbed Grid Control at an enterprise software social event? Maybe. Or maybe you just have password problems.
I recently ran across an interesting situation while I was working on an E-Business Suite environment: the adstrtal.sh and adstpall.sh scripts weren’t doing anything. They weren’t showing errors, but neither were they starting or stopping services. This post takes a look at the problem, unearths the cause, and presents a solution that isn’t always palatable, but in this case is warranted.
When installing Grid Control on a Linux or Unix platform, a recommended practice is to install the monitoring agent software as a user that doesn’t own the ORACLE_HOMEs to be monitored. This poses a challenge when configuring monitoring for some targets, particularly those based on Oracle Application Server 10g. This post lists some changes you can make to work around a variety of target discovery and metric collection errors.
This post describes how to remove the Workflow Notification Mailer from the list of targets that impact the reported status of an E-Business Suite instance monitored by Oracle Grid Control. This can be useful in test or dev systems, where users may not want a disabled notification mailer to be indicative of problems with the instance.
Here’s a quick list of reference links for deploying Oracle Grid Control 10.2.0.4 on Linux. If you’re starting out on a Grid Control deployment project, perhaps this will help to jump-start your own research. This is a non-exhaustive list, but it covers the basics reasonably well.
