Dear all, thanks or your kind and quick help so far. However, there are still questions open from our side, and your help in answering them is greatly appreciated. We currently have the following setup: 2 * Dell PowerEdge R815/II with 64 GB Memory and 2 * AMD Opteron 6172 with 12 Cores, 512k Cache and 2.1 GHz, 4x600 GB SAS ApacheDS 2.0 M15 Oracle JVM 1.7.0-25 Memory parameters for the ApacheDS JVM: -Xms2048m -Xmx2048m 30 nbthreads to handle the LDAP requests Indexes on all attributes that are searched (created BEFORE the data was loaded, size 10000) Ca. 20000 objects in the central partition Cache size for the partition: 10000 Do you have any indication as to how many parallel BIND sessions and searches we can support with such a setup? Is there a performance whitepaper of any sort for ApacheDS (or similar information)? If so: where can we find it?
Additionally, we are experiencing regular trouble with replication in our Multi Master Replication setup: If any of the servers is offline for a longer period of time, it will crash when booting up again and will delete all information in the partition that is being replicated. Just this weekend, the havoc was even greater: the partition was totally destroyed AND the server that was online all the time refused to start ApacheDS again, because the partition data on disk was destroyed. Of course, we followed the published documentation when setting up the servers and have unique replication IDs for our servers, etc. The system times are synchronized via NTP. We where able to restore the data from backup, but this clearly disqualifies ApacheDS as a production ready system. Can you give us any hints as to avoid such a catastrophic scenario in the future? Your help is greatly appreciated.
