Description:
Following are the changes made in BWWF hotfix3 to add this enhancement -

The following task attributes will be created as instance attributes on a need basis and can be removed from the Task class definition:
IC_RELATION_INFO
IC_TASK_ICON
IC_TAKS_NOTE
IC_TASK_UI_DOC
IC_WORK_TYPE

This does not seem to improve performance. However, there may be some savings in disk space.
Please NOTE, after deleting the above attributes, PC GUI will not work.

To delete the above properties, launch the Batch Registry under $TIBCO_HOME/bwworkflow/5.1/tools/bin and execute the following commands -
update class Task remove attribute  IC_RELATION_INFO;
update class Task remove attribute  IC_TASK_NOTE;
update class Task remove attribute  IC_WORK_TYPE;
update class Task remove attribute  IC_TASK_ICON;
update class Task remove attribute  IC_TASK_UI_DOC;

Note the attributes can also be converted to instance attributes by running the following
Batch Registry command INSTEAD of the remove attribute command -
update class Task convert attribute  IC_RELATION_INFO to INSTANCE;

If you need to preserver informantion or perserve functionality of the PC GUI you would do the above BUT
you will not get any reduction of size of the database if you convert to instance attrbiutes.

NOTE BENE: Any update class command to remove attributes or change to instance attributes may take
significant time to complete deplending on the size of the attributes table and the size of the tasks table.
