[Fedora-directory-users] Re: Migration from i-planet 52



All,
 
I tested this from scratch.
I used the ldif_2db function which did work much faster! 112 seconds...rather then about 20 minutes.
 
However I think the verify_db and db2_index functions are not in agreement.
 
Create indexes.
After my initial import.
[root ldap3 slapd-ldap3]# more out.after.final.txt

Please run db2index(.pl) for reindexing.
 
So then i reran db2index....verify_db again...same result.

I recently did an ldif backup of our iplanet 52 database. Its about an 88 MB ldif file.
I took this to a new FDS server Dell 850 3 ghz duel core 2 sata hard disks.
I ran an ldapadd  the data imported perfectly.
Then I tried to cutover some systems and give the database some load.
 
System went 200% processor
 
Eventually I realized I was missing indexes so I added them through the graphical tool.
 
The log seemed to do something like this
generating index 1%
generating index 2%
....
generating index 49%
Done
Seemed weird that they would jump from 49% to Done
At this point the new system was running at 100% processor
But the queries are running faster on our old 440 MHZ sparc t1 server52 database
 
I ran
DB ERROR: db_verify: Page 30: out-of-order key at entry 498
DB ERROR: db_verify: DB->verify: db/o_com/channelcontentowner.db4: DB_VERIFY_BAD: Database verification failed
 
then I tried db2_index. The program seemed to be in a tight loop complaining about 1 missing entry.
 
I do not realize how the data can be so corrupted right after an import.
 
These are someone generic symptoms. Any ideas? Thanks
