Purpose

The purpose of the mhttpd ODB page is to allow the user to browse, search and edit the ODB of an experiment. This gives a graphical alternative to using the ODB editor odbedit.

Access the ODB page

Click image(s) to enlarge

Figure 1: ODB Page example

The ODB Page is accessed from the Status Page (or one of the other Pages) by clicking on the menu-button ODB.

The top level ODB trees will be visible as key-links (i.e.links to a key) (Figure 1).

Note
If "ODB" button is not present on the Status Page, it may have been suppressed.


Browse the ODB

Figure 2: ODB Page Listing

By clicking on the key-links on the ODB page (Figure 1), the user can browse the various subtrees. By clicking on the "+" link adjacent to the "Value" heading (Figure 2) , the type and size of the keys are shown. This is equivalent to the odbedit commands ls and ls -l.



By clicking on a key, the user can change the value (unless password-protected or the key is write-protected - see Security). If web access is restricted, the user will be asked for a password the first time he/she attempts to edit a value.


Create a key

Click to enlarge thumbnails

The user can create a new key in a tree or subtree on the ODB Page by clicking the Create button. The Type of key to be created is selected from the drop-down list (Figure 3). The choices are shown in Table 1.

Note

Create allows you to create a subdirectory (Figure 3b) or a symbolic link (Figure 3c) as well as a regular key (Figure 3a).

Table 1: ODB Key Types
Key Types
Integer(32-bit) Float (4 bytes)
String Multi-line String
Subdirectory Byte
Signed byte Character (8-bit)
Word (16-bit) Short integer(16-bit)
Double Word (32-bit) Boolean
Double float(8 Bytes) Symbolic link


Delete a key

Figure 4: ODB page Delete a key

The user can delete a key in a tree or subtree by clicking the Delete button. The user selects which to delete from a list of the keys in the subtree (e.g. Figure 4).



Search the ODB for a key

Figure 5: ODB Page Find pop-up

Click on the Find button. A pop-up (Figure 5) appears in which the user types the relevant information.



Create Elog entry

Figure 6: ODB Page Elog pop-up

An elog entry can be created easily from the ODB page by clicking the

Create Elog from this page button. A pop-up will appear for the user to fill in (Figure 6).


Limitations

The ODB Page editor supports a subset of the functionality of odbedit. For example, the ODB Page editor does not support re-ordering or renaming ODB keys. For full editing capabilities odbedit must be used.
