Start with nsslapd-cachememsize - make that as large as possible and minimize nsslapd-dbcachesizeHi,There may be several attributes of interest to you as far as the memory consumption is concerned (http://www.redhat.com/docs/manuals/dir-server/8.1/cli/Configuration_Command_File_Reference-Plug_in_Implemented_Server_Functionality_Reference-Database_Plug_in_Attributes.html) :nsslapd-dbcachesizensslapd-cachememsize for every backend (by default, your data is in cn=userRoot,cn=ldbm database,cn=plugins,cn=config)nsslapd-import-cachesize (used only during ldif import)
You can also use the logconv.pl script to examine the access log to see what types of searches are being done and which are not indexed properly.You can adjust the corresponding values by monitoring the attributes like currententrycachesize or entrycachehitratio of cn=monitor,cn=userRoot,cn=ldbm database,cn=plugins,cn=config (http://www.redhat.com/docs/manuals/dir-server/8.1/cli/Configuration_Command_File_Reference-Plug_in_Implemented_Server_Functionality_Reference-Database_Plug_in_Attributes.html#Configuration_Command_File_Reference-Database_Plug_in_Attributes-Database_Attributes_under_cnmonitor_cnldbm_database_cnplugins_cnconfig)
2009/6/26 Tim Hartmann <[email protected] <mailto:[email protected]>>Hi! I was spending some time today trying to make sure that I was getting the most bang for my buck today an my replica's and I notices two items of interest that I was wondering if anyone else had input on! Firstly, after creating a number of indexs, my performance seems to be really good, the exception that I noticed was "finger" I noticed that finger takes a couple of seconds to return the data on RHDS whereas on OpenLDAP, it pops right now in real time! My first though was that I was doing an un-indexed search, but I can't for the life of me figure out what I might not be indexing that I should be! The second thing I noticed was that on my servers, which are RHEL5, running 32bit OS's with the PAE Kernels, RHDS doesn't ever actually address more then 3 gig of ram! I was looking through the documentations, and it looks like by raising the "Maximum Cache Size" I'll be able to allow RHDS to use more of the available memory.. did I get that right? Anyway, as always thanks in advance for all the help! This list has been a tremendous resource for an application that keeps on showing it's value in huge ways!
