MEM Utilization on AIX always showing 100%

Mem Util on AIX always shows a value of 100%, which is incorrect.

This is due to a unpublished bug 8526608

MOS Note Performance Tab Memory Utilization On Hosts Targets( monitored by 10.2.0.5 agent ) Shows 100% (Doc ID 849783.1)

This is also true for 11.1 Agents I noticed

I performed the following:

1. cd <agent_home>/sysman/admin/metadata
2. cp host.xml host.xml_20090623
3. edit host.xml and change
.
<ColumnDescriptor NAME=”freeMem” TYPE=”NUMBER” IS_KEY=”FALSE”
TRANSIENT=”TRUE” COMPUTE_EXPR=”(freeMemRaw / 1024.0)” HELP=”NO_HELP”>
.
to
.
<ColumnDescriptor NAME=”freeMem” TYPE=”NUMBER” IS_KEY=”FALSE”
TRANSIENT=”TRUE” COMPUTE_EXPR=”(freeMemRaw )” HELP=”NO_HELP”>
.
.
4. restart agent.

For me this solved the problem

Upgrading Agent 10.2.0.5 to 11.1 as easy as 1,2,3…

After the upgrade of OMS 10.2.0.5 to 11.1 in my test environment, I started upgrading some of the remote agents.

OEM GC 11.1 includes an Upgrade Agent feature that allows you to upgrade the 10.2.0.5 Agent to 11.1 on multiple nodes at once.

Check out this document to see what I did and how easy it is.

Installing Agent 10.2.0.5.0 and upgrading to 10.2.0.5.2 using OEM Grid Control

After installing OEM GC 10.2.0.5.2 (see my previous post), I did an installation of a new Agent on a different Host, pushing it from the OMS.

After installing the 10.2.0.5.0 Agent, I upgraded the Agent to 10.2.0.5.2 by using the OEM Procedure “Patch Agent”

I have created a document describing all steps I went through

Deployment of an Agent – Preparation

To be able to do deployment of an agent with EM the following preparations must be taken care of:

Download the Mass Agent deployment zip file from otn.oracle.com
Oracle Enterprise Manager 10g Grid Control Management Agents (10.2.0.4) for Windows, Linux x86, and Solaris SPARC

On each OMS
Unzip the zip file (Linux_x86_64_Grid_Control_agent_download_10_2_0_4_0.zip) to $OMS_HOME//sysman/agent_download/10.2.0.4.0/.

$ unzip Linux_x86_64_Grid_Control_agent_download_10_2_0_4_0.zip -d /u01/app/oracle/product/10.2.0/oms10g/sysman/agent_download/10.2.0.4.0

$ pwd
/u01/app/oracle/product/10.2.0/oms10g/sysman/agent_download/10.2.0.4.0/linux
oracle@lsrv0004.rf.rabobank.nl:OMS:/u01/app/oracle/product/10.2.0/oms10g/sysman/agent_download/10.2.0.4.0/linux_x64

Modification of configuration files
On each OMS server the following checks should be made:

Check that the file $OMS_OH/sysman/agent_download/10.2.0.4.0/agent_download.rsp contains the correct settings.
#——————————————————————————-
#Name : s_OMSHost
#Datatype : String
#Description: Fully-qualified hostname where the OMS resides
# Example: “foo.us.oracle.com”
#Component : oracle.sysman.top.agent
#——————————————————————————-
s_OMSHost=”omserver1″

#——————————————————————————-
#Name : s_OMSPort
#Datatype : String
#Description: Port number used to communicate with the Management Service
# If port 4889 is in use by another application, please reset.
#Component : oracle.sysman.top.agent
#——————————————————————————-
s_OMSPort=”4889″

Normally these values were set to the correct values, during installation of the OMS.

Check that the file $OMS_OH/sysman/prov/resources/userPaths.properties contains the correct settings:

SSH_PATH=/usr/bin/ssh
SCP_PATH=/usr/bin/scp

Next you need to setup the ssh configuration, allowing to ssh from you OMS server to the servers you want to deploy to:

$ cd $OMS_HOME/sysman/prov/resources/scripts
$ ./sshConnectivity.sh -hosts “
