While I have my olcDatabase={1}hdb.ldif in cn=config directory, I can't seem to get slapd to generate the DB_CONFIG file. My options include olcDbCacheSize, olcDbNoSync etc.. For my reading, if these are specified and DB_CONFIG file exists, (it doesn't as slapd complains about it missing with -d 99), it should generate a DB_CONFIG from these settings.
Any ideas?

The directives you indicate configure the bdb/hdb backend, and do not generate a DB_CONFIG.
The only directive that changes the DB_CONFIG is the "dbconfig" directive. Try olcDbConfig in your back-config.
Note that "if these are specified and DB_CONFIG file exists" is exactly opposite -- the file must NOT exist at the time of slapd startup.
ok, here is my confusion.. What's the difference between the following:
olcDbCacheSize:1000 in my hdb.ldif file AND olcDbConfg: set_cachesize 0 10485760 0
I added the olcDbConfig and <presto> DB_CONFIG file gets created. So many thanks for the assistance, just curious as to the differences..

see slapd-bdb(5) for "cachesize" (olcDbCacheSize) and Berkeley DB's documentation for set_cachesize. They refer to totally different and unrelated caches.
