Re: [Freeipa-users] How do I modify the entry cache size?

Thanks for the reply and the link Rich!

dbmon.sh is a handy tool indeed.

I read the instructions and upped my entry cache size to 2gb because I have enough ram.
Everything went well until
service dirsrv restart

I Got the following errors:
[06/Feb/2015:10:07:35 -0500] - slapd stopped.
[06/Feb/2015:10:07:37 -0500] attr_syntax_create - Error: the EQUALITY matching rule [caseIgnoreIA5Match] is not compatible with the syntax [1.3.6.1.4.1.1466.115.121.1.15] for the attribute [dc]

Oddly enough everything appears to be working. Are these messages safe to ignore?

This is definitely not related to the cache size.

Not sure what the problem is - looks like something has done an override of the standard schema definition of dc.  http://tools.ietf.org/html/rfc4519 defines it with syntax 1.3.6.1.4.1.1466.115.121.1.26.

rpm -q 389-ds-base

find /etc/dirsrv -name \*.ldif -exec grep 0.9.2342.19200300.100.1.25 {} /dev/null \;


Another run of dbmon.sh shows that my entry cache was increased. 

Thanks,

Hi Everyone. I'm trying to troubleshoot some issues I'm having. I want to increase the entry cache size
I'm trying to follow the directions here
/usr/lib/mozldap/ldapmodify -D "cn=directory manager" -w secret -p 389 

dn: cn=database_name, cn=ldbm database, cn=plugins, cn=config
changetype: modify
replace: nsslapd-cachememsize
nsslapd-cachememsize: 20971520

Is this the correct way to do this? How do I find out what the "
cn=database_name" is supposed to be?

see https://github.com/richm/scripts/wiki/dbmon.sh - the script will tell you what the names of your databases are.

Thanks,
