RE: RE: dblink problem ( ORA-02019)
Hi thanks for your mail. Dick , I checked out , both db's are 8.1.7.2 and have same db_domain as world. i also tried out Suzy Vordos' suggestion : selected "name,value,ismodified from v$paramater" for both databases , but the result for both is same . So change in init.ora or "alter system" after db startup does not seem likely. regards Ratnesh -Original Message- Sent: Tuesday, July 16, 2002 6:57 PM To: Ratnesh Kumar Singh; Multiple recipients of list ORACLE-L Folks, Since I recently slammed into this unexpected wall I'll pass along the experience. A couple of weeks ago I upgraded an 8.0.5.2.1 instance to 8.1.7 and subsequently at OTS's request to 8.1.7.4. To make a long story short most things with database links worked OK, but a describe across one did not (ORA-02019). The problem ended up being a small error in Oracle's INIT parameter documentation. Back in 8.0.5.2.1, due to a bug introduced, you needed to have DB_DOMAIN=.WORLD or DB_DOMAIN=.VICR.COM. Note the '.' before the domain. Well in 8.1.7, or sometime before that, they fixed the bug, but forgot about those of us who don't always follow the 'yellow brick road'. So if your having problems with ORA-02019's take a second and check this parameter in your init.ora. I changed mine & the problems went away.

Re: dblink problem ( ORA-02019 )
If db_domain is in fact set in B's init.ora, you might check if: 1) there are multiple init.ora's and the one you're looking at isn't the one used, 2) if the database has been bounced since the init.ora was changed. Also from sqlplus type: show parameter db_domain, to see if it's set.

On both databases, check "select * from global_name" and compare the result to "select * from dba_db_links".

RE: dblink problem ( ORA-02019 )
Hi ratnesh, try this checks first : 1.Check if the GLOBAL_NAMES=TRUE in init.ora parameter. 2.In the sqlnet.ora check whether the WORLD domain is mentioned in both. 3.Tnsnames.ora file ,the database name should be test.world like that. 4.How are you creating the database link with which qualifier you are using?Are you using the world domain or simply creating the link with a particular domain. This is not clear. IF you can send me exactly how you are creating the database link in both the databases we can know where you went wrong. Anyway frist try the above check steps first.
