Guide

Oracle Database is a major enterprise relational database system used worldwide for mission-critical applications.

Why Agent Required

Oracle databases run on enterprise servers that cannot directly upload data to the web. The DataMeans Agent connects securely to your Oracle environment for extraction.

What You Can Extract

  • Oracle 11g, 12c, 18c, 19c, 21c
  • Tables, views, and materialized views
  • Indexes and constraints
  • Stored procedures and functions (documentation)
  • Partitioned tables

What You Get Out

DataMeans converts your data into multiple modern formats:

OutputDescription
csv/{TableName}.csvOne CSV file per table with all row data
xlsx/{TableName}.xlsxExcel workbook per table (omitted for tables over 1,048,575 rows, 16,384 columns or 8,000,000 cells - see note below)
xls/{TableName}.xlsLegacy Excel format per table (omitted for tables over 65,535 rows, 256 columns or 150,000 cells - see note below)
json/{TableName}.jsonJSON array of records per table
json/{TableName}.jsonlNewline-delimited JSON (streaming-friendly)
postgres.sqlPostgreSQL CREATE TABLE + INSERT statements
mysql.sqlThe same schema and rows, in MySQL dialect
sqlite.sqlThe same schema and rows, in SQLite dialect
ansi.sqlThe same schema and rows, in portable ANSI SQL
sqlserver.sqlThe same schema and rows, in SQL Server (T-SQL) dialect
report.jsonStructured conversion report
report.mdHuman-readable conversion summary

How It Works

Agent availability: The DataMeans Agent is currently in development and not yet available for download. The steps below describe the planned workflow. To get notified when Oracle support launches, reach out via our About page.

  1. Download and install the DataMeans Agent on a system with Oracle client access
  2. Configure Oracle connection credentials (TNS or direct connection)
  3. Select schemas and tables to extract
  4. The Agent extracts and uploads securely to DataMeans
  5. Review and download your converted data

Planned Support

  • Full schema extraction
  • Complete data extraction
  • Type mapping to PostgreSQL equivalents
  • Foreign key relationship detection
  • Large table streaming

Known Limitations

  • Requires DataMeans Agent installation
  • Oracle client libraries required on Agent host
  • Stored procedures documented but not converted
  • Very large tables may require scheduled extraction

Note on the Excel formats. An .xlsx sheet holds at most 1,048,575 rows of data and 16,384 columns, and a legacy .xls sheet 65,535 rows and 256 columns. Rather than ship a file that looks complete but is silently cut short, DataMeans leaves a table out of any Excel format it does not fit and notes it in the job report. The .xlsx copy is also left out for tables of more than 8,000,000 cells (1,048,575 rows of 12 columns is 12.6 million), which take too long and too much memory to write, and the .xls copy for tables of more than 150,000 cells, which the legacy format takes far too long to write. The CSV, JSON and SQL outputs always contain every row.

Not available for hosted uploads. This system is read over a direct database connection by the DataMeans Agent, which is still in development. Contact us to plan a migration.

Questions

Can I convert Oracle Database with DataMeans today?

Not yet. Oracle Database is not available for self-serve upload, and support is still in development. Get in touch and we'll tell you where it stands and help plan the migration.

What will DataMeans convert Oracle Database to?

Once Oracle Database is available, exports will match every other system we support: clean CSV, Excel, JSON & SQL, one file per table, with a structured report of exactly what was extracted.

Is my data secure?

Yes. Your files are encrypted in transit and at rest, and they're deleted automatically: within 7 days if you don't go ahead with a conversion, and when your download window ends if you do. We never sell or share your data, and we never use it to train machine-learning models.
