hi all,

i want to ask something regarding import/export utility... recently i commenced a replication project via materialized views. after successfully completing it, i wanted to take a safe point backup, so i opted for a full database export of both of my master site database and materialized view site's database (plus cold backups of both databases too). then i recreated the two databases & gave the same set of database names (global database names), set the oracle net etc..., imported the dump files at its respective sites and tried the replication activity but it didnt work...


there were alot of warnings while at the import activity, seemingly they were not of great signaficance but may be
that were the main reason of replication failure...

can some 1 advise me, is there any way out from this...? or what should be the best backup type for a repliction
project where there are database links and FROM clauses in the snapshots...

i use oracle Database 10g Enterprise Edition Release 10.2.0.1.0

following are some of the warnings that appeared in the import activity...

hoping for help...

regards

1. Physical hot backup

2. RMAN backup

3. Cold backup but not export / import

Your database link is missing, probably because it is in the SYS schema and not included in the export. You need to create it.

I already suggested this in your other topic on exactly this question, but you never repled. Not very polite of you. Frown

hi john watson,

i couldnt find out my previous topic, sory for that...

i would like to tell you that all of my links reside in the system schema and the schema whose objects are replicated (hamza). Plus the export backup which i am talking about is the full database export. then why are the links not backed up???

hoping for even more courtesy
regards

Prove it! What do you have in dba_db_links on both daabases?
And what are your export and import scripts?
