Install the Application Package

Install the application package on an existing Exalead CloudView instance running the same version, that is, having the same hotfixes installed.

This instance is typically the Exalead CloudView instance in production. By default, the installer uses the variables defined in the configuration of the target/production Exalead CloudView instance.

Install the Application Package

Before you begin: Make sure that the target Exalead CloudView instance is running, and has the same version that was used to generate the package.
  1. Go to <DATADIR>/bin/ and run cvadmin.
  2. To deploy an application on your running instance, run the following command: 

    cvadmin apps install [args]

    For example, 

    cvadmin apps install apps-file=onecall_app_v.xxx.zip

    Where the args are:

    Table 1. cvadmin apps install arguments
    Option Description
    [apps-file] Path to the archive file containing the application you want to install. (Value type: FILE)
    [datadir] Override DATADIR variable. (Value type: FILE)
    [hostname] Override HOSTNAME variable. (Value type: STRING)
    [installdir] Override INSTALLDIR variable. (Value type: FILE)
    [instance] Override instance name variable. (Value type: STRING)
    [port] Override port number variable. (Value type: PORT)
    [propertyFile] Path to properties file containing variable mapping. (Value type: STRING).

    Once you have generated an application package using the cvadmin cvapps generate command, unzip the package to define the placeholders for the variables you want to use. You can define placeholders in any file in the config directory.

    You can use the following placeholders:

    • ${MYPARAMETER} - If your property file contains a key named MYPARAMETER, the value will be replaced without any transformation. If it does not contain any key, there will be no replacement.

    • ${MYPARAMETER_CRYPTED} - If your property file contains a key named MYPARAMETER_CRYPTED, the value will be replaced without any transformation. If it does not contain this key, a second lookup will be run to find the MYPARAMETER key. If that key is found, the value will be first ciphered using the security key of the targeted DATADIR and then replaced. If it does not contain any key, there will be no replacement.

    • ${VAR_+X} - Calculates a new value using a well-formed integer variable as base. For example, if ${VAR_+1} is found in your property file, it searches the VAR value and replaces ${VAR_+1} with VAR value + 1. This is typically useful when you want to increment port numbers.
