Temp Space issue

 Hi Friends,

We had been facing an issue with temp segment for some times now.

We are running on Oracle 10g.

Below is my issue description:

There are two database DB1 and DB2. Both are running in same Oracle 10g version with same OS level and database level patches.

Databases are running in two seperate Sun Solaris Server.

 

1) Current Scenario:

 

Log into DB1 and running the following:

 

Insert into DB1.table

select ...... from table1@DB2,table2@DB2

where......;

 

It is causing temp segment error in DB2. We have 200 GB of temp space available but this eats up all the 200GB temp space and throws the temp segment error.
