DTP Connectivity Ganymede Project Plan: First Draft

Revision as of 10:50, 7 September 2007 by Brianf.sybase.com (Talk | contribs) (Connectivity)

Back to DTP Ganymede Project Plan

DTP Connectivity Ganymede

Beside each entry, we will put the following acronyms:

  • MH for Must Have
  • LTH for Like To Have

For Ganymede, we will focus on Must Have (MH) items before Like to Have (LTH) items.

Connectivity

Things to Consider...

1) Ability to pre-populate a connection UI with driver definitions. (This already exists with the ability to auto-create a default instance of a particular driver template at startup.) (MH) (BZ entry: 202641[1])

2) Provide common user interface for selecting existing connection profiles. Features of this UI should include filtering of the existing connections based on an arbitrary set of attributes and it should display an extensible set of properties for the selected connection. (This already partly exists with the ability to host the DSE on a dialog page/composite/wizard/property/preference page where necessary.) (MH) (BZ entry: 202643[2])

Here is the UI from WTP to use as a starting point:Existing conns.png

3) Provide best-practices for prompting users when to create new profiles, select existing profiles, and prompt the user for authentication information. Perhaps create code sample to help demonstrate best practices. (MH)

4) Ability to inject from a runtime instance of a profile at startup to populate a profile in the DSE. This may be supported already with the repository code. (MH)

5) Filtering needs to become much more extensible and flexible. Perhaps split out catalog-loader (SQL-level) filtering from client-level (viewer-level) filtering. Also provide the capability to use client-level filtering by default, if a db-specific extension did not implement catalog-loader filtering. (MH) (BZ entries: 200140[3], 177272[4], 199689[5])

6) Provide extensible encryption capabilities for exporting profiles. Perhaps a new extension point to register an encryption method. Need to research different encryption methods. (LTH)

7) Provide plug-in wizards to aid driver template and connection profile development. (MH) (BZ entries: 151738[6])

8) Focus on sorting and see if we can come up with ways to make that work for various levels of the DSE within the Platform's Common Navigator Framework (see if any changes are upcoming for Ganymede) (LTH) (BZ entries: 150592[7])

9) Connection timeout such that connections in the DSE will be closed if unused for a certain amount of time specified in a preference page. This is a WTP feature that needs to be ported to DTP. It will probably need to be redesigned as the DSE in DTP is not exclusive to database connections and it may not make sense to timeout connections to other types of servers. (MH)

Perhaps look at it so that each individual server type implements an extension point (perhaps an extension on the CP extension point), listens in a server-specific way for disconnects, and then triggers a reconnect. It will be difficult to handle in the generic case.

Here is the UI from WTP to use as a starting point: Data preferences.png

10) Provide enablement support for JNDI connections for getting a pooled JDBC connection through a JNDI service. Check out Apache Tomcat 5.5.x and BEA WebLogic 8.1 as examples. Both are fairly simple to use and configure. However, Tomcat does not support client-side access, which we will need in the DSE. (LTH) (BZ entries: 202640[8])

11) Clean up internal Discourage Access warnings in Connectivity. (MH) (BZ entries: 201125 [9], 201126 [10], 201127 [11], 201136 [12])

Open Data Access (ODA)

1) Integrates with Database (JDBC) connection profile category (MH)

2) Integrates with the visual SQL Builder and SQL Query Model for use by ODA consumer applications (MH)

3) Support for multi-dimensional result sets (LTH)
