Hello again,
Run test050 to get simple configuration examples for n-way
replication. For mirror mode configuration see http://www.openldap.org/doc/admin24/replication.html, part 17.3.2 and 17.4.4
I have examined a bit tests scripts provided with openldap-tests rpm
from
Mandriva. First it is not very clear how to run scritps,
Where did you look for documentation? I could add some detail on how to run the scripts in the description of the package, or a readme file, but it really is just the standard test suite ...
I looked in /usr/share/doc/openldap[-servers] and /usr/share/openldap/tests, scroll through run and opened Makefile I also read urpmf --description openldap-tests. I think it would be really nice if ./run --help could give a sentence of description for each switch instead of just lising them.
For now, just './run test050' or similar.
FInanly to the topic: sniff of the test050 scritpt:
add: olcMirrorMode olcMirrorMode: TRUE EOF .........
It shows, that it is adding MirrorMode TRUE. So why?
The configuration directive may have been overloaded when multi-master was added (after mirrormode). AFAIK it allows the database in question to both have a syncrepl directive, yet take updates from a DN besides the updatedn (see the description on the slapd.conf man page).
are you saying, that in multimaster configuration I have to have updatedn directive to be able to do writes? I didnot find anything about that in documentation http://www.openldap.org/doc/admin24/replication.html. On the other hand man page says: updatedn <dn> This option is only applicable in a slave database.
man page of slapd.conf states: "mirrormode on | off - This option puts a replica database into
"mirror"
mode...." Adding this to my conf file lets me do writes to masters, but I don't
want
MirrorMode, I want MultiMaster.
See the rest of the paragraph, which continues to say:
"Update operations will be accepted from any user, not just the updatedn."
Regards, Buchan
In thread "explain diff between multimaster and mirror mode" I found out, that mirrormode is kind of high availability implementation for openldap. In my case I want to have multimaster replication, which could allow me to do writes to different master servers at a time. It contradicts mirrormode, which says, that writes should be directed to one master and switched only on failure of first master.
I would like to stress my question again: how to do writes in multimaster configuration? Simply following documentation didn't let me do writes to any master.
