Before you can create or read sealed documents, your installation of Oracle IRM Desktop must be connected to the server (Oracle IRM Server) that holds the user and context information for the documents to be created or read.
If you have been sent a sealed document and want to read it, simply opening the document will initiate connection to the server. You may be asked to provide login details, after which you will be able to use the sealed document to the extent that your rights allow. You will find that the server to which you have been connected is listed on the Servers tab of the Oracle IRM Desktop Options dialog.
If you wish to seal a document to a context hosted by a server that is not yet listed on the Servers tab, you will need to connect to that server manually. See "Connecting to Oracle IRM Server Manually".
