Hi Rich and all,
Thank you a lot for pointing out the place of the scripts.
The scripts are found at the place specified and trued, they are
working great in general, but there are still some places needs help:
1, there are no manual or help regarding the command options. Not sure
where the normal usage could be looked up.
[root@ipamaster scripts-PEGACLOUDS-COM]# man db2ldif
No manual entry for db2ldif
[root@ipamaster scripts-PEGACLOUDS-COM]# ./db2ldif --help
Usage: db2ldif {-n backend_instance}* | {-s includesuffix}*
[{-x excludesuffix}*] [-a outputfile]
[-N] [-r] [-C] [-u] [-U] [-m] [-M] [-1]
Note: either "-n backend_instance" or "-s includesuffix" is required.
[root@ipamaster scripts-PEGACLOUDS-COM]#
http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/9.0/html/Configuration_Command_and_File_Reference/Command_Line_Scripts.html
In general - you can use the .pl scripts when the server is running, the
non-.pl scripts when the server is down. So, use ldif2db.pl to do an
online import.
Also, with ipa, you can use -n userRoot or -n ipaca depending on if this
is the ipa instance or the CA instance.
2, what is the 'official' way increase file descriptors for IPA & 389
Directory server??
[root@ipamaster scripts-PEGACLOUDS-COM]# ./db2ldif -s
'dc=pegaclouds,dc=com'
Exported ldif file:
/var/lib/dirsrv/slapd-PEGACLOUDS-COM/ldif/PEGACLOUDS-COM-pegaclouds-2012_04_30_164542.ldif
[30/Apr/2012:16:45:42 -0700] -
/etc/dirsrv/slapd-PEGACLOUDS-COM/dse.ldif: nsslapd-maxdescriptors:
nsslapd-maxdescriptors: invalid value "8192", maximum file descriptors
must range from 1 to 1024 (the current process limit). Server will
use a setting of 1024.
[30/Apr/2012:16:45:42 -0700] - Config Warning: -
nsslapd-maxdescriptors: invalid value "8192", maximum file descriptors
must range from 1 to 1024 (the current process limit). Server will
use a setting of 1024.
...
db2ldif doesn't use file descriptors in the same way as the server does
when it is using them to listen and service incoming connections - just
ignore that message
3, the ldif2db command will abort when IPA(Directory Server) is running.
I have to stop IPA first, then run ldif2db, and fireup IPA at the
end. It may not be a bad thing to avoid potential data base
corruption. But please confirm whether this is a feature or a bug.
[root@ipamaster scripts-PEGACLOUDS-COM]# ./ldif2db -s
'dc=pegaclouds,dc=com' -i
/var/lib/dirsrv/slapd-PEGACLOUDS-COM/ldif/PEGACLOUDS-COM-pegaclouds-2012_04_30_163506.ldif
importing data ...
...
[30/Apr/2012:16:50:00 -0700] - Backend Instance: userRoot
[30/Apr/2012:16:50:00 -0700] - Unable to import the database because
it is being used by another slapd process.
[30/Apr/2012:16:50:00 -0700] - Shutting down due to possible conflicts
with other slapd processes
Use ldif2db.pl
Thanks.

There are a couple of RFEs open to develop this information. My
understanding (and this is something that

Thanks for pointing out a way to do partial backup/restore.
But the command db2ldif, or its sibling command ldif2db can not be
located on IPA master/replica.
look in /var/lib/dirsrv/scripts-YOURDOMAIN-YOURTLD
The IPA servers only install 389-ds-base and 389-ds-base-libs RPMs.
and the two commands doesn't show up anywhere.
Could anyone elaborate how to use the two template commands, or
please point me to the document or http link(s) is enough. Thanks a lot.
[root@ipamaster script-templates]# rpm -qa | grep 389
389-ds-base-1.2.9.14-1.el6_2.2.x86_64
389-ds-base-libs-1.2.9.14-1.el6_2.2.x86_64
[root@ipamaster script-templates]# rpm -ql 389-ds-base
389-ds-base-libs | grep -P 'db2ldif|ldif2db'
