The Preferences section contains the following tabs:

Data File Editor

You can set the following preferences when using the Data File Editor:

Records per page
Set the amount of records you want to display per page. The more records you display per page, the more memory that is required; therefore, reduce the amount of records per page if you receive memory problems. Use the and icons to navigate the pages of records.
Note: You must restart Data File Editor before any changes to this setting take effect.
Temporary Directory
Set the location of a temporary directory that is required in order to filter a data file. You can specify either an absolute or a relative (to the current working directory) path. An invalid path, or no path at all, will produce an error when you attempt to apply a filter.
Padding Character
Each new record is immediately padded with the characters you specify here for both ANSI and EBCDIC encoding. Enter the character in the top cell of the box next to the encoding name.


If you are connecting to an enterprise server using an SSL connection, use the Certificate Authority Trust Store setting to specify the trust store that contains the trusted root certificate used by the connection.

To use this setting requires that you have already created a trust store that includes a CA root certificate or (for non-production scenarios only) a self-signed certificate on your client, and that the enterprise server that you are connecting to has a valid server certificate (which is used to establish the server/client connection) and private key (for encryption) configured.

To configure an enterprise server to use an SSL connection, create a listener that specifies the server certificate and keyfile. This type of listener does not automatically start when you start the enterprise server; it must be authorized after the server has started, by entering the key's passphrase, before the listener starts. The tutorial Tutorial: Configuring SSL Security in the Server explains how to configure an enterprise server to use an SSL connection.

The required trust store is Java-specific, and so we recommend that to create the trust store, you use the keytool utility from the JDK that matches your version of Java; for more information, refer to the keytool utility documentation on the Oracle web site (
