Oracle Enterprise Manager Cloud Control 12c(12.1.0.1.1) Agent install:

安装前准备：

下载最新版本EM Cloud Control Agent【Linux_Grid_Control_agent_download_11_1_0_1_0.zip】上传至<OMS_HOME>/sysman/agent_download/11.1.0.1.0/下。关于这一个步骤可以参考EM Cloud Control Agent安装程序的【instructions.txt】文件说明，参考如下：

Instructions for installing the agent

Download the Linux_Grid_Control_agent_download_11_1_0_1_0.zip file from OTN.

1. Methods for mass deployment of agents

a. Copy the downloaded file to <OMS_HOME>/sysman/agent_download/11.1.0.1.0 directory.(create <OMS_HOME>/sysman/agent_download/11.1.0.1.0 directory, if it doesn't exist.)

b. cd <OMS_HOME>/sysman/agent_download/11.1.0.1.0

c. <OMS_HOME>/bin/unzip Linux_Grid_Control_agent_download_11_1_0_1_0.zip

Once the agent software the is staged in the above mentioned directory either of the following methods can be used for mass agent deployment:

-- agentDownload script.

If agent_download.rsp doesn't exists at <OMS_HOME>/sysman/agent_download/11.1.0.1.0 directory then execute the following:

mv agent_download.rsp.bak agent_download.rsp

Then follow the instructions in section 10 of the Enterprise Manager Grid Control Basic Installation and Configuration Guide available at:

http://www.oracle.com/technology/documentation/oem.html

-- Agent Deploy Application. Details on using this method can be found in Enterprise Manager Grid Control Basic Installation and Configuration Guide.

Additionally, refer to section 10 of the the Enterprise Manager Grid Control Basic Installation and Configuration Guide available at:

http://www.oracle.com/technology/documentation/oem.html

2. Silent installation of the agent

For silent installation using DVD, copy the <DVD>/response/additional_agent.rsp file to a location on the local machine and modify the Value Unspecified entries accordingly. Invoke the runInstaller by executing:

<DVD>/<runInstaller> -silent -responseFile <location>/additional_agent.rsp

For silent installation using the extracted agent download zip file, copy the <UNZIP_DIR>/response/additional_agent.rsp file to a location on the local machine and modify the Value Unspecified entries accordingly. Invoke the runInstaller by executing:

<UNZIP_DIR>/<runInstaller> -silent -responseFile <location>/additional_agent.rsp

For detailed information on using silent installation method to install the Management agent please refer to .Enterprise Manager Silent Installations. described in the Enterprise Manager Grid Control Basic Installation available at:

http://www.oracle.com/technology/documentation/oem.html

3. NFS Mounted Agent Installation

Enterprise Manager 11g R1 allows you to install a single Agent on a shared NFS filesystem, and then have multiple hosts share that same ORACLE_HOME. Details on installing a NFS mounted agent can be found in section "NFS Agent Installation" of the Enterprise Manager Grid Control Basic Installation Guide available at:

http://www.oracle.com/technology/documentation/oem.html

This URL takes you to the Enterprise Manager documentation library page. Click View Library and on the page that comes up, click the Documentation tab, and then click the name of the document you want to access.

oem agent install

Instructions for installing the agent

Download the Linux_Grid_Control_agent_download_11_1_0_1_0.zip:
Download the Linux_Grid_Control_agent_download_11_1_0_1_0.zip file from OTN.

1. Methods for mass deployment of agents

a. Copy the downloaded file to <OMS_HOME>/sysman/agent_download/11.1.0.1.0 directory.(create <OMS_HOME>/sysman/agent_download/11.1.0.1.0 directory, if it doesn't exist.)

Once the agent software the is staged in the above mentioned directory either of the following methods can be used for mass agent deployment:

-- agentDownload script.

If agent_download.rsp doesn't exists at <OMS_HOME>/sysman/agent_download/11.1.0.1.0 directory then execute the following:

groupadd oinstall
useradd -g oinstall oem

If you have an Oracle RAC Cluster with multiple nodes, then you must install a Management Agent on each of the nodes separately. In other words, in the Add Host Targets Wizard, you must add each node explicitly as a destination host.

The Add Host Targets Wizard uses SSH to establish connectivity between Oracle Management Service (OMS) and the remote hosts where you want to install the Management Agents.

Only SSH1 (SSH version 1) and SSH2 (SSH version 2) protocols offered by OpenSSH are supported for deploying a Management Agent.

make-3.81
binutils-2.17.50.0.6
gcc-4.1.1
libstdc++-4.1.1
libXtst-1.0.1-3.1(i386)

Destination Host Time Zone Requirements
export TZ='Asia/Shanghai'

<AGENT_HOME>/sysman/admin/supportedtzs.lst
/m01/oracle/agent/core/12.1.0.2.0/sysman/admin/supportedtzs.lst

Verify whether the SSH server can access the TZ environment variable by logging in to the OMS host, and running the following command:

ssh em12c echo $TZ
ssh xpli $TZ

sudo/pbrun/sesu/su SSH Requirements:
If you are using sudo as your privilege delegation tool, and you do not want to set the oracle.sysman.prov.agentpush.enablePty property to true, do one of the following:
Include Defaults visiblepw in the /etc/sudoers file, or enter the sudo command with the -S option for Privileged Delegation Setting on the Installation Details page.
For information on how to access the Installation Details page, see Installation Procedure.
Comment out Defaults requiretty in the /etc/sudoers file.

sudo/pbrun/sesu/su Requirements (for Root User):
Ensure that the installing user has the privileges to invoke the id command and the agentdeployroot.sh script as root. Grant the privileges in the configuration file of your privilege delegation tool.
For example, if you are using sudo as your privilege delegation tool, include the following in the /etc/sudoers file to grant the required privileges:
oracle ALL=(root) /usr/bin/id, /home/oracle/agentibd/*/agentdeployroot.sh
Here, oracle is the installing user, and /home/oracle/agentibd is the agent base directory.

Unset the CLASSPATH environment variable.You can always reset the variable to the original value after the installation is complete.

Central Inventory (oraInventory) Requirements:
Ensure that you have read, write, and execute permissions on oraInventory on all remote hosts. If you do not have these permissions on the default inventory (typically at /etc/oraInst.loc) on any remote host, then ensure that you specify the path to an alternative inventory location by using one of the following options in the Additional Parameters field of the Add Host Targets Wizard. However, note that these parameters are supported only on UNIX platforms, and not on Microsoft Windows platforms.

INVENTORY_LOCATION=<absolute_path_to_inventory_directory> -invPtrLoc <absolute_path_to_oraInst.loc>

Installing User Requirements:
If the central inventory owner and the user installing the Management Agent are different, then ensure that they are part of the same group.
Also ensure that the inventory owner and the group to which the owner belongs have read and write permissions on the inventory directory.
For example, if the inventory owner is abc and the user installing the Management Agent is xyz, then ensure that abc and xyz belong to the same group, and they have read and write access to the inventory.

Browser Requirements:
If you use Microsoft Internet Explorer 8 or 9, do the following:
Turn off the compatibility view mode. To do so, in Microsoft Internet Explorer, from the Tools menu, click Compatibility View to disable it if it is enabled. Also, click Compatibility View Settings and deregister the Enterprise Manager Cloud Control console URL.
Enable XMLHTTP. To do so, from the Tools menu, click Internet Options. Click the Advanced tab, and under the Security heading, select Enable native XMLHTTP support to enable it.

INVENTORY_LOCATION=/m01/oracle -invPtrLoc /m01/oracle/emagent_oraInst.loc

[oem@xpli oracle]$ cat /m01/oracle/emagent_oraInst.loc
inventory_loc=/u01/app/oraInventory

问题原因：之前/etc/hosts文件中vm10g主机ip配置错误，原IP指向em server IP所致，变更IP后原来的ssh认证不可用。

解决：删除EM server和agent服务器oem用户下【.ssh】目录下/home/oem/.ssh/known_hosts文件中vm10g部分，然后重新配置vm10g主机ssh认证即可。
