Scheduling

Run individual jobs according to the prescribed schedules listed on the List of Jobs. However, be aware that because large jobs -- defined as BIB loads of 3000 records or more -- will place significantly more stress on the Voyager keyword index and may affect system performance, the Voyager keyword index will be turned off for all loads larger than 3000 records. Please observe the following guidelines:

• The maximum number of records in a file loaded with the LSTOOLS shouldn't exceed 15000 records. Split the files containing more than 15000 records appropriately.
• Public announcements about large loads should be postponed to a day after the next keyword index regeneration has occurred.
