A strange error about cursor and dblink

Question

My dbms:Oracle8i Enterprise Edition Release 8.1.7.4.0
I have a stored procedure, which inserts records from a remote database into a local table.
The 'insert' statement have similar pattern:
insert into table_a
select table_b.columns from table_b@dblink
where table_a.column in (select table_b.column from table_b@dblink);
commit;
There are about 100 'insert' statement in my procedure. But there is same error messages at the same
place when the procedure is run. The error messages:ora-01000:maximum open cursors exceeded,ora-02063:
preceding line from dblink. I have manually run the 'insert'statements before the error place and after the error place.
The before and after statements are both OK.
From google.com, I have learned that 'commit' will clear the implicit cursors from 'insert' statement. So I think
the problem is ora-02063. Again, keywords 'ora-01000 ora-02063'from google.com, I found 'alter session close
database link dblink' might solve the problem. I have add the 'alter session' statement after each 'commit' in
my procedure. Unfortunately, same error happened again at the same place.
I am puzzled. Would you like to give some advice? Thanks a lot!

Hello
Well, the best place to lookup error messages is here....

It's also where all the rest of the database documentation is. As for this error, too many open cursors, as it suggests, one session has too many open. From the statement you are using to select the data, it seems like you are forming the statements dynamically, is this the case? If so, you're using cursors, and so there's a good chance you aren't closing them.
