Constraints:
- The maximum allowed length for User and group names is 32 characters.
- Do not begin a name with the prefix dm. Documentum reserves this prefix for its own use.
- The name must consist of ASCII characters.
- User and group names are case sensitive.
- It is good practice not to choose names that conflict with DQL reserved words.
Note:
- Avoid using SQL and DQL reserved words for names. If a name must match a DQL reserved word, enclose the name in double quotes whenever you use it in a DQL query.
- The name must consist of characters compatible with the server os code page of the Content Server
- The name of user or group must be unique among the user and group names in the repository. (This means a user cannot have the same name as a group)
- It is better to restrict names to letters, digits, underscores. If special characters are used, third-party applications must take special care to escape them while working with Documentum (epecially while using DQL queries)
- To escape special characters such as spaces, apostrophes, – enclose the string in Single quotes
- To escape DQL reserved keywords, enclose the string in double quotes when referenced
- For groups, it was noticed that System changes all characters in the name to lower-case
- It was observed in practice that using ‘/’ & ‘\’ in the name causes problems during creation of accounts and user home-cabinets
- Other special characters tested were (, ), and the system accepts these names. However, they must be escaped while using DQL queries.
Recommendation:For ensuring that other applications can work with a unified group-set, I recommend that the names should be kept as simple as possible and restricting to letters, digits & underscores. Spaces, apostrophes, brackets, slashes, single-quotes, double-quotes, $, #, @, &, *, etc should be avoided as other applications
