Unable to Extend TEMP space for CLOB

Question

Hi,
I have a data extract process and I am writing the data to a CLOB variable. I'm getting the error "Unable to Extend TEMP space" for the larger extracts. I was wondering if writing the data to a CLOB column on a table and then regularly committing would be better than using a CLOB variable assuming time taken is not an issue.

Answer 1

You do not need to add more temp files. This is not a problem of your temp tablespace. This is the problem of temp segments in your permanent tablespace. You need to add another datafile in EDWSTGDATA00 tablepsace. This happens when you are trying to create tables and indexes. Oracle first does the processing in temp segments(not temp tablespace) and at the end oracle converted those temp segments into permanent segments.
Also, post the result of below query
select file_name,sum(bytes/1024/1024)in_MB,autoextensible,sum(maxbytes/1024/1024)in_MB from dba_data_files where tablespace_name='STAGING_TEST' group by file_name,autoextensible order by FILE_NAME;
