In this cloud-era it’s almost weird to explore stuff on-premises, but I did…. In this case a slightly Higher Availibility configuration of Oracle Enterprise Manager (OEM) that doesn’t cost anything, is not disruptive to the existing configuration and gives a tiny bit more confidence during patching of OEM : Always […]
I was a newbie with Virtualbox and Enteprise Manager 12C with OEL6 (64-bit) was quite a new combination, so what can go wrong…?
You could do the following:
- read an article about installing OEL6 here or
- read an article about installing software on Virtualbox
The metric 'swap utilisation (%)' on the node where Grid Control resides, shows permanently a very hig value. Red Hat Linux, 64-bits, 32GB RAM, 4GB swap. Adding 4GB to the swap-file solved the problem.
Using rdbms 11.2 as the repository for our Grid Control environmont, noticed a lot of the same errors in the alert file of the repository or/and the target database:
NI cryptographic checksum mismatch error: 12599.
TNS for Linux: Version 220.127.116.11.0 – Production
Oracle Bequeath NT Protocol Adapter for Linux: […]
After installing and configuring application server, the agent on that server started to sent messages like 'The number of active connections is ..' . But.. there are no connections yet on the system (as far as I know)! Grid Control (OMS + agent) = 10.2.05, application server 10.1.2.0.2
Grid Control is calling >> “Difference between OMS system time and Agent system time is 121 mins and has exceeded the critical threshold 120 mins”
The system time runs too fast on a (Suse) Linux-based (kernel 2.6) virtual machine, while the ntp has been configured. There are a lot of documents […]
Short one this time, all in favour of getting my green ‘pie’ in Grid Control management server.
Grid Control: 10.2.0.5. Discoverer: 10.1.2.x
In Grid Control, after upgrade to 10.2.0.5, a Discoverer target shows down in the list, while it’s functioning quite well.
It seemed an old bug (Grid Ctrl 10.1.04) is still not […]
After installing Oracle Application Server 10.2.0.2, with corresponding OID, Grid Control 10.2.0.5 gave me the obove mentioned error, and the the item OID gave a 'metric collection error'. To fix the metric collection error downloaded and applied Patch 5686191 on top of OID product.This is a sql-script to run against the OID-repository.
Tried to prepare my 10.2.0.4 – Grid Control for an upgrade to 10.2.0.5. See also http://download.oracle.com/docs/cd/B16240_01/doc/install.102/e10953/toc.htm .
Updated for example the shared_pool_size as 128MB as minimum size (see below for other recommended fixed parameter settings), although I think it also will work while setting the sga_target. Changed […]
Platform: application server 10.1.2.0.2 on Suse Linux 9. Grid Control agent 10.2.04.
All components within the application server are up, but the home page of Grid Control showing it down.
Underlying cause: bug in discovering ports by the agent. Agent discovering process gets Forms url Port from < HOME_IAS>/10.1.2/forms/server/target2add.xml. But this port […]
