This release of Experian Pandora introduces the following enhancements:

  • Support for Metro2 file conversion
  • A globally configurable maximum number of allowed table versions
  • Dates and times consistency when interchanging between databases
  • Logging and user assistance improvements

We've also fixed a number of bugs.


Metro2 File Conversion

It is now possible to convert files from the Metro2 (Packed 366 or Character 426) file formats into a CSV ready for loading into Experian Pandora. Although this functionality is fully tested, test data has been in short supply and it is possible that some aspects of the standard have not been fully catered for. Any such issues will be dealt with should they arise.

Metro2 files should be copied into the drop folder (C:\pandora\data\metro2 by default but this is configurable). They will be automatically converted and, when successful, will be available in Experian Pandora's list of files ready to be loaded. Any errors which occur during the loading process will be logged; successful loads will have the input file removed from the drop directory whilst failures will be left in place. Three attempts will be made to load a file after which time it will be blacklisted until a server restart.

Once converted, records loaded into Experian Pandora will contain a column for all fields of the base record and all fields for each optional segment whether or not they are populated in the source. Whilst there are plans to update the functionality in the future, at present any record containing multiple J1 and J2 segments will see only the last populated instance of each segment written to the destination.

The setting to enable raw format means that numbers dates will not be processed on conversion and will just be stored as a string of digits. This is provided as a diagnostic tool for users who are having difficulty getting their data to convert correctly.

Version management

Better management and visibility of the maximum number of versions that can be kept of each table.

The default value for the maximum number of versions of a table that will be kept remains at 32 but now can be configured by the user. Once set, this default will be applied to all new and existing tables that do not have the maximum individually set. Furthermore, the maximum can now be set across a number of tables at the same time.

It is now possible to view the maximum version count for each table as it appears along with the number of versions actually kept in the table drilldown.

Times and Dates in JDBC

In versions of Experian Pandora prior to v5.6.1, the handling of dates and times when interchanging values between database and Experian Pandora has been inconsistent and unreliable. This is in fact a very complex area because often, it is not clear which timezone a date and time relates to. The design goal for this change has been to hide the complexity of timezones from the user by attempting, as far as possible, to leave displayed times unchanged whilst maintaining the integrity of the data.

Specifically, the following points are now true:

  • JDBC Timezone setting has been removed and is ignored
  • Timezone settings applied to individual JDBC connections are ignored
  • As far as possible, users see times and dates in Experian Pandora as they would in their database
  • Where dates and times in the database have a timezone attached, the value is converted to UTC
  • Experian Pandora stores and displays all dates and times in UTC (or as though they were UTC)
  • Dates and times are written back to the database target as UTC; that should mean they are unchanged 


When logging load table actions, the repository id and table version are recorded.

Table expression cache start/completed actions are now logged. Log entries include table name, version, id and expression name.

JDBC connection strings will now only be shown in errors when the JDBC Debug option is turned on.

A log message will now appear to show that a period of database disconnection has begun. 

User Assistance

Tooltips have been added and updated on the JDBC connection Automation/Refresh Details tabs. An Experian Pandora documentation page has also been created.

Phone Number Validation

The phone number validation libraries have been updated so validation for international phone numbers should now be more accurate. This requires a full installation (you can't upgrade to this version to get the improved phone validation).

Bug fixes

Scheduled tasks will not restart after a non working day.
Any task not scheduled to run on a working day would fail to run after a non-working day unless other scheduled tasks continued to run in the meantime.

Language settings are incorrectly referenced when loading dates in the format YYYY-mm-dd.
This date format is now invariably parsed as year, month, day regardless of the locale of the source data.

Files with associated DDL load yyyy-mm-dd dates incorrectly, and changing the language does not fix it.
The fix for 40165 also applies in this situation where the file is described by a DDL file.

"Default Standardisation Rules" server setting appears to require a server restart but doesn't prompt.
A server restart is now prompted when this value is edited.

JDBC Connection period does not work
A number of fixes made to ensure that the connection period is respected

Cannot export nulls to sql server varchar/char field
Experian Pandora does not distinguish between nulls and empty strings and attempts to hide the concept from the user. An Experian Pandora null (which is a true null or an empty string) will be written to a database field as null if the field is nullable, or otherwise as an empty string. Experian Pandora strings comprising only spaces are always written as is.
Note that this means that if data is read from, and subsequently written back to, SQL server then any empty strings in nullable fields will be converted to null.

Prevent Ghost Table versions appearing
When the Maximum Table Versions setting is changed for a table, ensure the table information accurately reflects the number of table versions stored.

Disabled Connections allow tables to be loaded and exported to

  • Prevented loads from occurring from disabled connections
  • Prevent drilldown exports to a disabled connection - including loads/exports that are scheduled for later.

JDBC connection refresh does not show new tables for particular database types (e.g. Cassandra & Mongo)
New tables are now detected with a connection refresh

Unable to update records via Experian Pandora for various JDBC Drivers
It is now possible to insert/update/delete records for Mongo and Cassandra databases

JDBC Load Query keeps running when Load job is stopped in Experian Pandora - SQL
When loading a table from a SQLdatabase, if you stop the job on Experian Pandora, the SQL query now stops in the source SQL database.

Port error when attempting to connect to SQLServer Data Direct Driver
This driver now automatically sets the allowPortWithNamedInstance property such that a connection is still made when a named instance connection is supplied as well as a port number.

Client fails to startup on initial attempts if configured database connections time out
Regardless of the connection status of database connections, the client now starts up on the first attempt.

DNS caching never refreshes
The IP address for a hostname is no longer cached indefinitely for database connections so if the IP of a hostname changes, it will now be picked up.

"Drilldowns (All Versions)" drilldown on a table duplicates all drilldown names
Ghost versions of drilldowns are no longer displayed in the "Drilldowns (All Versions)" panel.
