Created attachment 326755 [details] cvs commit log Reviewed by: nhosoi (Thanks!) Fix Description: Added a check box for "use auto cache size". If this is checked, a value of -1 will be saved for nsslapd-import-cache-autosize which will tell the server to use the default auto cache value. If this is not checked, a value of 0 will be saved which will tell the server to use the number from nsslapd-import-cachesize. If the check box is checked, the import cachesize field will be disabled. Here are a couple of screen shots. https://bugzilla.redhat.com/attachment.cgi?id=326699 https://bugzilla.redhat.com/attachment.cgi?id=326700 Platforms tested: RHEL5 Flag Day: no Doc impact: yes - will have to document the new UI verified DS 8.1 RHEL 5 When checked: nsslapd-import-cache-autosize: -1 When unchecked: nsslapd-import-cache-autosize: 0 An advisory has been issued which should help the problem described in this bug report.

Description of problem: Directory Console | Configuration | Database Settings | LDBM Plug-in Settings Import cache size shows 20000000 bytes by default and no item for the Import cache autosize. On the other hand, the database configuration sets nsslapd-import-cache-autosize: -1 by default, which means the import cache autosizing is enabled and it sets 50% of free physical memory. The real server configuration is not reflected to the Console UI. Also, even if a customer changes the value on Console, it does not change the import cache size since autosizing is enabled and has a higher priority. Proposal: if import-cache-autosize is on (-1 or some positive value), the Console Import cache size displays "auto". If the value is changed by a user, the value is assigned to nsslapd-import-cachesize and nsslapd-import-cache-autosize is disabled (by setting 0). If this is easy, if "auto" is the value of Import cache size, it'd be nice to have another ratio box to store the percentage of autosizing. But I don't think it's that necessary. We experienced that setting higher number (> 60%), cache autosizing tests often failed due to the lack of memory. So, we don't want customers to set high number. Instead, we'd like them to stay with 50% (-1). That's said, hiding the ratio might be preferable. I've added "By default, ..." sentence to the Admin Guide, Tuning Directory Server Performance chapter as follows. > In the Import Cache Size field, enter a value corresponding to the amount of memory in bytes that you want to make available for import. By default, the value is “auto” and 50% of the free memory is allocated for the import cache. If you are creating a very large database from LDIF, set this attribute as large as possible, depending on the memory available on your machine. The larger this parameter, the faster your database will be created.
