Maximum Number of Databases Searchable at One Time
If system performance is a concern, you can restrict the number of databases that can be searched at one time. Use the PowerPAC profile Remote databases: Maximum number that can be searched at once. Valid values are 1-25; the default setting is 10. The profile is available at the system, library, and branch levels. The PAC connection organization’s setting is used.
Note:
You cannot set a maximum number of databases searchable at one time that is fewer than the number of databases you have selected for follow-on searches. See Remote Database Usage Settings for PowerPAC. Conversely, you cannot select more follow-on databases than your setting for the maximum number searchable at one time.
