TS 6.5 index CLT

System

I have the following questions regarding the index CLT commands for TeamSite 6.5:

1. I indexed a branch, then I added another extended attributed to the FieldMapping.xml. After that, I tried iwndxrefreshbr, but no file is re-index. Do I have to use iwndxrmbr to remove the index collection and then re-index the whole branch after changes being made to the FieldMapping.xml?

2. If I disable event-based updates, and also disable the Interwoven Event Subsystem, can we still run iwndxrefreshbr with -i (incremental) option? Is the -i option based on submit events?

Thanks.
