Recreating an Old EPM Cloud Environment for Audits

Use the script in this section to create a self-service solution to maintain an up-to-date library of snapshots for your Oracle Enterprise Performance Management Cloud environment. You require an environment dedicated for the purpose of upgrading and maintaining a library of up-to-date snapshots.

EPM Cloud supports snapshot compatibility for one monthly cycle only; you can migrate maintenance snapshots from the test environment to the production environment and vice versa. However, the auditing requirements of some customers may necessitate restoring snapshots from multiple years on the latest environment, and accessing application in a short period of time.

You should schedule this script to run once every month to convert the available snapshots and make them compatible with the latest EPM Cloud patch level. Oracle recommends that you run the script after the third Friday of the month to ensure that all issues within the production environment have been resolved.

Note:

You cannot use this script to update Account Reconciliation and Oracle Enterprise Data Management Cloud snapshots.

How the Script Works

For every snapshot stored by the customer, the upgrade script completes these tasks using EPM Automate :
  1. Using the information in the input.properties file, logs into an environment

  2. Uses the recreate command to refurbish the environment

  3. Imports the snapshot into the environment

  4. Runs daily maintenance on the environment, which results in the snapshot being converted into the format compatible with the current EPM Cloud patch level.

  5. Downloads Artifact Snapshot (the maintenance snapshot) into a folder. If you recreated an 18.05 environment by uploading snapshots from snapshots/18.05, Artifact Snapshot is downloaded into snapshots/18.06.

Running the Script

  1. Create the input.properties file and update it with information for your environment. Save the file in a local, directory. This directory, referred to as parentsnapshotdirectory in this discussion. Contents of this file differs depending on your operating system.

    Make sure that you have write privileges in this directory.

  2. Create upgradeSnapshots.ps1 (Windows) or upgradeSnapshots.sh (Linux/UNIX) script and save it in the parentsnapshotdirectory where input.properties is located.

  3. Create a sub-directory, for example, snapshots, within the parentsnapshotdirectory.

  4. Within the directory that you created in the preceding step (snapshots), create a sub-directory for the monthly snapshot that you want to convert to make it compatible with the current tEPM Cloud patch level. Name the directory using the YY.MM format; for example, 18.05 for the directory to store the May 2018 snapshots.

  5. Copy snapshots into the appropriate sub-directory. For example, copy the snapshots for May 2018 into snapshots/18.05.

  6. Launch the script. On Linux/UNIX, run ./upgradeSnapshots.sh.

If you are using the PDF version of this document: To avoid line breaks and footer information that will render these scripts unusable, copy them from the HTML version of this topic.

Windows

Create input.properties and upgradeSnapshots.ps1 script by copying the scripts in this section.

Creating input.properties

username=exampleAdmin
userpassword=examplePassword
serviceurl=exapleURL
identitydomain=exampleDomain
proxyserverusername=proxyServerUserName
proxyserverpassword=proxyPassword
proxyserverdomain=proxyDoamin
parentsnapshotdirectory=C:/some_directory/snapshots

Updating input.properties

Note:

If authentication at proxy server is not enabled for your Windows network environment, remove the properties proxyserverusername, proxyserverpassword, and proxyserverdomain from the input.properties file.

Table 3-3 input.properties Parameters

Parameter Description
username User name of a Service Administrator.
userpassword Password of the Service Administrator .
serviceurl URL of the environment that is used for this activity.
identitydomain Identity domain of the environment.
proxyserverusername The user name to authenticate a secure session with the proxy server that controls access to the internet.
proxyserverpassword The password to authenticate the user with the proxy server.
proxyserverdomain The name of the domain defined for the proxy server.
parentsnapshotdirectory Absolute path of the directory that is to be used as the parent directory of the directory that stores the snapshots to be processed. Use forward slashes (/) as directory separators.

Creating upgradeSnapshots.ps1
