keep getting errors on this DSA
Perhaps it's the data itself that is corrupted - I just don't see it.
I dump and reload...
cd /usr/local/var/openldap-data
mv DB_CONFIG ../
rm -fr *
rm -fr ../openldap-logs/*
/usr/local/sbin/slapadd -l /root/slapcat.ldif
# /usr/local/bin/db_verify __db.001
db_verify: Page 0: bad magic number 0
db_verify: Page 0: bad page size 0
db_verify: DB->verify: __db.001: DB_VERIFY_BAD: Database verification
failed
and more/other errors for db_verify __db.002 > 005
I know that I have properly patched db-4.2.52 with all patches...but
just to make sure, I ran each of the patches - listed below (2 patches
for db4 and 1 transaction patch)
If anyone can give me a clue here, I would appreciate it.
for clarity, I have added more info below.
Thanks
Craig
to be sure that I had db4 installed correctly...
I went to build folder of db4
cd db-4.2.52/build_unix
make realclean
# cat Config
CFLAGS='-O2'
CXXFLAGS='-O2'
../dist/configure \
--prefix=/usr/local \
--enable-compat185
# ./Config
# make
# make test
# make install
then I downloaded openldap-2.2.23 and 'untarred'
I went to build folder of openldap-2.2.23
# cat Config
