Re: server restart - lost data?

thank you for your response Jon.

i have couple of db_recover commands on my system.

db_recover
db2_recover
db33_recover
db41_recover

I don't know which one to use. I used first one and got error. then i tried
all others and got errors too. i did not use with -v option. Also i don't
remember the errors.

As you suggested backing up using slapcat seems to be a good idea.

thanks,
shashank
