Re: Creating a "big" database... large LDIF file. automated procedure?
Thanks Quanah... finally got a chance to use MakeLDIF, and was successful
in creating a large LDIF file. An LDIF file with 1M entries is almost
600MB!
Incase others are interested, here's what i did to create this file...
The MakeLDIF tool is located at slamd/tools/MakeLDIF. I used the template
they provided (example.template) to create my LDIF file. It creates a file
with X entries (specified at the top of the template), with each entry
containing random data.
To create an LDIF file with 1,000,000 entries…
Download slamd-2.0.0-alpha1.zip from http://www.slamd.com/download.shtml
Extract all files (to a new folder… doesn’t matter where)
Modify the “define numusers” value in
slamd/tools/MakeLDIF/example.template to be 1000000 (define
numusers=1000000)
Open a command prompt, cd to slamd/tools/MakeLDIF, and enter the
following:
java -jar MakeLDIF.jar -t example.template -o example.ldif
When processing completes, you’ll have an ‘example.ldif’ file in
slamd/tools/MakeLDIF that contains 1,000,000 entries.
Thanks again

Hi again. Thanks again for your responses to my prior posts.
So far, all of my experience with OpenLDAP has been with databases with a
minimal number of entries... 200 at the most. I'd like to do some
performance experiments with a much larger database, say 10,000 database
entries or so. What would you recommend for creating such a database?
(Entries don't have to have real, sensible data... maybe the
distinguished
name is an integer that increases by 1?) Is there an automated way
for
creating such a database?
The MakeLDIF tool with slamd. And 10k entries is not large. :) I've
routinely tested 1M+, and that's small these days for a number of places.
