PowerShell Scripting to Replicate Oracle SCM Data to MySQL

The CData Cmdlets for Oracle SCM offer live access to Oracle SCM data from within PowerShell. Using PowerShell scripts, you can easily automate regular tasks like data replication. This article will walk through using the CData Cmdlets for Oracle SCM and the CData Cmdlets for MySQL in PowerShell to replicate Oracle SCM data to a MySQL database.

After obtaining the needed connection properties, accessing Oracle SCM data in PowerShell and preparing for replication consists of four basic steps.

The following connection properties are required to connect to Oracle SCM data.

• Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
• User: The username of your Oracle Cloud service account.
• Password: The password of your Oracle Cloud service account.

Collecting Oracle SCM Data

1. Install the module:

   Install-Module OracleSCMCmdlets

2. Connect to Oracle SCM:

   $oraclescm = Connect-OracleSCM -Url $Url -User $User -Password $Password

3. Retrieve the data from a specific resource:

   $data = Select-OracleSCM -Connection $oraclescm -Table "Carriers"

   You can also use the Invoke-OracleSCM cmdlet to execute pure SQL-92 statements:

   $data = Invoke-OracleSCM -Connection $oraclescm -Query 'SELECT * FROM Carriers WHERE ActiveFlag = @ActiveFlag' -Params @{'@ActiveFlag'='false'}

4. Save a list of the column names from the returned data.

   $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name

Inserting Oracle SCM Data into the MySQL Database

With the data and column names collected, you are ready to replicate the data into a MySQL database.

1. Install the module:

   Install-Module MySQLCmdlets

2. Connect to MySQL, using the server address and port of the MySQL server, valid user credentials, and a specific database with the table in which the data will be replicated:

   $mysql = Connect-MySQL -User $User -Password $Password -Database $Database -Server $Server -Port $Port

3. Loop through the Oracle SCM data, store the values, and use the Add-MySQL cmdlet to insert the data into the MySQL database, one row at a time. In this example, the table will need to have the same name as the Oracle SCM resource (Carriers) and to exist in the database.

   $data | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "Carriers" -Columns $columns -Values $values }

You have now replicated your Oracle SCM data to a MySQL database. This gives you freedom to work with Oracle SCM data in the same way that you work with other MySQL tables, whether that is performing analytics, building reports, or other business functions.

Notes

• Once you have connected to Oracle SCM and MySQL in PowerShell, you can pipe command results to perform the replication in a single line:

  Select-OracleSCM -Connection $oraclescm -Table "Carriers" | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "Carriers" -Columns $columns -Values $values }

• If you wish to replicate the Oracle SCM data to another database using another PowerShell module, you will want to exclude the Columns, Connection, and Table columns from the data returned by the Select-OracleSCM cmdlet since those columns are used to help pipe data from one CData cmdlet to another:

  $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name | ? {$_ -NotIn @('Columns','Connection','Table')}
