Re: can slapcat dump dbb file which size larger than 9G?

[Gary Allen Vollink <gvldap@corvu.com>]

Wait a minute.  Slapcat, in it's default call dumps to stdout.  That
means that you should be able to get around the limit by using an OS
redirect...

slapcat > huge_output.ldif

If your shell can't handle that (I've run into similar issues with
TAR), you should be able to do something like this...

slapcat | gzip > huge_output.ldif.gz

I don't have this much data to test with, but this should work (along
with the -z parameter suggested previously).  The resulting output will
definitely be less than 2 GB (unless your data size is greater than 15
to 20 GB), as near 90% compression would be expected...

slapcat -z 9999999 | gzip > huge_output.ldif.gz

Thanks,

i'am afraid the slapcat can not support this.

 

But i don't know how to modify slapcat.c to let it support dump file > 2GB

Could be you're trying to save a file greater than the OS 2GB limit. In
which case you'll have to save bits of the tree at a time with
ldapsearch, GQ or similar.
