Hi
We are having 4 million users to migrate, all data exported from oracle to multiple ldif files. Imported 1 million till now, took almost 28 hours. and openldap-data dir of about 28G. openldap version 2.4.33 bdb version 5.1.29 RHEL 6.3 RAM 8G 4 cpu , system is a VM.
Currently running slapadd output
- /apps/openldap/sbin/slapadd -q -c -w -f
/apps/openldap/etc/openldap/slapd.conf -l /root/User9.ldif bdb_monitor_db_open: monitoring disabled; configure monitor database to enable . 2.27% eta 21h31m elapsed 29m57s spd 1.6 k/s str2entry: invalid value for attributeType postalAddress #0 (syntax 1.3.6.1.4.1.1466.115.121.1.41) slapadd: could not parse entry (line=394416)

1. There are too many errors like above.
Its seems to be taking weeks go import whole data.
It takes about 2 - 4 hours in order to slapadd 4 mio.entires, depending on file system and disk type.
is there any tool or any other approach which we can use to make it fast,Or we are going with wrong configuration. Or we have to switch to ODS or RHDS
There is no necessity for other tools, just modify the ldif file.
