Security Features in Documentum

March 22, 2010 Comments off

The following security features are part of a standard Content Server installation. Some of these are enabled automatically and some are optional. The features are:

User authentication

  • User authentication occurs automatically, regardless of whether Docbase security is active.

Password Encryption

  • Password encryption protects passwords stored in a file. Content Server automatically encrypts the passwords it uses to connect to third-party products such as an LDAP directory server.

Application-level control of SysObjects

  • Application-level control of SysObjects is an optional feature that you can use in client applications to ensure that only approved applications can handle particular documents or objects.


  • User privileges define what special functions, if any, a user can perform in a Docbase.

Object-level permissions

  • Object-level permissions are assigned using ACLs. Every SysObject in the Docbase has an ACL.


ACLs (Access Control Lists)


Auditing and tracing facilities

  • use to monitor the activity in your Docbase.

Electronic signoff

  • Electronic signature (generated and managed by Content Server)
  • Digital signature (electronic signatures in formats such as PDKS #7, XML signature, or PDF signature)
  • Simple signoffs (the least rigorous way to supply an electronic signature. Simple signoffs are implemented using the Signoff method.)

User Privileges:




0 None User has no special privileges
1 Create Type User can create object types
2 Create Cabinet User can create cabinets
4 Create Group User can create groups

Documentum Process Management Features

Process Management in CMS


–          A workflow formalizes a business process such as an insurance claims process or an engineering development process. After the business process is formalized in a workflow definition, users can use the definition to repeatedly perform the business process.

–          Workflows can describe simple or complex business processes. A workflow can be serial, with activities occurring one after another and only one activity in progress at a time. A workflow can be parallel i.e. consist of two or more activities, all happening concurrently. Or, a workflow can combine serial and concurrent activity sequences.

–          You can also create a cyclical workflow in which the completion of an activity restarts a previously completed activity. For example, SOW documents which require re-validation over a period of time.

Life Cycle:

–          A lifecycle is a set of states that define the stages in an object’s life. The states are connected linearly.

–          An object attached to a lifecycle progresses through the states as it moves through its lifetime. A change from one state to another is governed by business rules. The rules are implemented as requirements that the object must meet to enter a state, actions to be performed on entering a state, and actions to be performed after entering a state.

–          You cannot attach a lifecycle definition to a lifecycle i.e. one life cycle can not use another life cycle in its definition.

Heart of Content Management System (CMS) – Content Server

  1. It is the server that talks to the docbase.
  2. A multi-featured process that provides access to the data and content files that constitute a docbase.
  3. Is accessed by the user through a suite of products provided by Documentum.
  • Documentum Client Applications.
  • Custom Applications
  • Interactive Utilities

Content Management Services

  1. Data Dictionary
  2. Storage and Retrieval
  3. Versioning
  4. Assembly and Publishing (Virtual Documents)

Data Dictionary: The data dictionary stores information about object types and attributes. The data dictionary is a collection of information about object types and their attributes stored as internal data types in eContent Server.


  • Applications can use data dictionary information to enforce business rules or provide assistance for users.
  • Another use of Data Dictionary is we can also have a set of default values for the attributes.

Storage: All files are stored in a single repository called as Docbase. While storing, each document gets unique object ID.

Retrieval: Is obtained by the use of Documentum Query Language (DQL) or API.

Versioning: Maintaining different versions of a document. Default is 1.0.

  • checking out
  • checking in: same , minor and major version

Assembly and Publishing (Virtual Documents):

A virtual document is a container document. It is a way to combine documents whose contents have a variety of formats into one document. For example, suppose you want to publish a document with text content, a document with graphic content, and a spreadsheet as one document. By making the three documents components of one virtual document, you can publish them as one document.
