26 Upgrading Oracle Management Agent Using agentDownload Script

This chapter describes how you can upgrade an existing Oracle Management Agent 10g Release 4 or 5 (10.2.0.4.0 or 10.2.0.5.0) to Oracle Management Agent 11g Release 1 (11.1.0.1.0) in silent mode, using the agentDownload script. In particular, this section covers the following:

Overview

You can upgrade an existing Oracle Management Agent 10g Release 4 or 5 (10.2.0.4.0 or 10.2.0.5.0) to Oracle Management Agent 11g Release 1 (11.1.0.1.0) in silent mode using the agentDownload script. The agentDownload script is a script that helps you upgrade Management Agents, silently without having to use the GUI screens of Enterprise Manager Grid Control. The script is available on the source host where Oracle Management Service (OMS) is installed, and it is run from the node where the Management Agent needs to be upgraded. For more information about the agentDownload script, see Overview.

Before You Begin

Before you begin, keep in mind the following points:

  • If you are upgrading a Management Agent whose software binaries were used for installing additional Management Agents, either using the Shared Agent Deployment Wizard or the nfsagentinstall script, then before proceeding any further, read Chapter 27, "Upgrading Shared Oracle Management Agent".

Prerequisites

Before upgrading the Management Agent, ensure that you meet the prerequisites described in Prerequisites.

Upgrade Procedure

To upgrade an existing Management Agent using the agentDownload script, follow these steps:

  1. On the destination host where you want to upgrade the Management Agent, open a browser to access the OMS URL and download the script.

    UNIX Platform Microsoft Windows Platforms
    Using Browser
    http://<oms_host>:<oms_port>/agent_download/<version>/<platform>/agentDownload.<platform>
    

    For example:

    http://host1.servers.com:4889/agent_download/11.1.0.0.0/linux/agentDownload.linux
    

    Using Command Line

    wget http://<oms_host>:<oms_port>/agent_download/<version>/<platform>/agentDownload.<platform>
    

    For example:

    wget http://host1.servers.com:4889/agent_download/11.1.0.0.0/linux/agentDownload.linux
    
    Using Browser
    http://<oms_host>:<oms_port>/agent_download/<version>/<platform>/agentDownload.vbs
    

    For example:

    http://host1.servers.com:4889/agent_download/11.1.0.0.0/win32/agentDownload.vbs
    

    Using Command Line

    wget http://<oms_host>:<oms_port>/agent_download/<version>/<platform>/agentDownload.vbs
    

    For example:

    wget http://host1.servers.com:4889/agent_download/11.1.0.0.0/win32/agentDownload.vbs
    

  2. Run the agentDownload script on the destination host using the following command. For other options, you can use with the command, see Table 26-1.

    UNIX Platform Microsoft Windows Platforms
    ./agentDownload.<platform> -u -o <absolute_path_to_old_oracle_home> -b <absolute_path_to_new_installation_base_directory>
    
    For example:
    ./agentDownload.linux -u -o /john/OracleHomes/agent10g -b /peter/OracleHomes
    
    ./agentDownload.vbs u o <absolute_path_to_old_oracle_home> b <absolute_path_to_new_installation_base_directory>
    
    For example:
    ./agentDownload.vbs u o /john/OracleHomes/agent10g b /peter/OracleHomes
    

    Note:

    The -b argument can be skipped if you have specified the installation base directory for the parameter ORACLE_AGENT_HOME_LOCATION in the agent_download.rsp file. However, if you still pass the argument -b in the command, then the installation base directory specified in the command is honored and the one specified in the response file is ignored.

    Note:

    On Microsoft Windows, do the following:
    • If you are upgrading a non-shared RAC Agent, then run the following command on every node of the cluster:

      ./agentDownload.vbs u o <absolute_path_to_old_oracle_home> b <absolute_path_to_new_installation_base_directory> -local

    • If you are upgrading a shared RAC Agent, then do the following:

      (a) On one of the nodes, run the following command:

      ./agentDownload.vbs u o <absolute_path_to_old_oracle_home> b <absolute_path_to_new_installation_base_directory> -local

      (b) On each of the other nodes, run the following command from the Oracle home of the Management Agent:

      <ORACLE_HOME>/bin/agentca -u -c <comma-separated_list_of_nodes'_short_names> -r <absolute_path_to_response_file>

      Here, the response file passed in the above-mentioned command contains the following parameter with the fully qualified name of the node on which you are invoking the command:

      s_hostname=<fully_qualified_name_of_node>

  3. If the Management Agent that you are upgrading was not secure, then the agentDownload script prompts you to specify the agent registration password.

Arguments You Can Pass While Running agentDownload Script

The following are the arguments you can pass while running the agentDownload script:

Note:

On Microsoft Windows, do not hyphenate the arguments. For example, the -b argument when run on Microsoft Windows is b.

Table 26-1 Arguments Supported by agentDownload Script
