Connect to different Oracle databases in PL/SQL code
Hi,

Here around 250 oracle databases in our company. Extract information from each database and load them in my target databases.

Info like database name, host name, port number…etc

So here I' have written the Oracle Procedure, looks like we can't use

CONNECT abc/password@' || DB_CUR1.DB_NAME ||';'


DB_CUR1.DB_NAME --> define the cursor and db_name has list of 250 oracle database name(SID).

I knew its possible using database link, but need to create 250 database links.

Please let me know if there is any alternative way to connect to each database store them in target database


Any help that will make job easy

SQL*Net is the only way to connect to a remote Oracle instance.

It appears that you'll have to create 250 database links.

You have a chicken & the egg dilemma.
For each remote instance you need a tnsnames.ora file entry which includes hostname, service_name & port.
Only you or others at YOUR site can provide these details.
Sorry, but my crystal ball in is the shop for repair.
