Implementation of Incremental Backup Topic by gotuchintu 15 Oct 2010 backup

Here in EIM, the challenge with the backup was backup window was growing steadily. When it reached 11 hour window, it became an issue. With the continuous ETL loads & so many report users it became nearly impossible to have that big backup window. Here, ETL almost pulls the real time data from the legacy systems and puts them into DW.

On investigation, it was found that only one table in the database takes almost 9 hours to get backed up. The size of the table was 6 TB +. Then we planned to implement incremental backup for that big table.

Parsing/Response Topic by TeraLab 03 Feb 2012 tasm

Hi All,

I've two questions:

  1. For a query, which is in responding mode, does increasing the priority (Higher Workload) help?
  2. When does the parsing happen for the query in TASM environment? Is it before the query is pushed to delay queue (if it goes to delay queue) or after the query is released from the delay queue (i.e) when the query gets active?
