Hello, could you help me to set `nsslapd-db-home-directory`?

Hello, Marko!

 

I would like to change that path in order to move the cache in a RAM fs.

I tried with

` /usr/sbin/dsconf -D "cn=Directory Manager" -w *** ldap://tst-example.com:389 backend config set  --dbcachesize=209715200 --db-home-directory=/dev/shm/dirsrv/slapd-default/dbcache`

but it fails with:

`Error: Server is unwilling to perform - nsslapd-db-home-directory can't be modified while the server is running.`

I tried to follow these instructions:

https://access.redhat.com/documentation/en-us/red_hat_directory_server/11/html/performance_tuning_guide/tuning-db-cache#db-cache-on-ram-disk

but even if I stop the directory, I change the entry in the dse, I restart the directory, then I still see:

Yes, this is the way. 

1. Stop the instance;

2. Change dse.ldif attribute value;

3. Start the instance.

 

`nsslapd-db-home-directory: /var/lib/dirsrv/slapd-default/db`

Could you please check you /var/log/dirsrv - errors log?

Also, is your SELinux and other permissions are set properly for the directory?

Sincerely,

Simon

 

My 389ds-base is `1.4.3.22`.

Thank you very much
Kind Regards
Marco
