Re: How do you calcuate the temp space needed for view?

Your database having db_block_size 2K so max extents are 121. You may alter your temp tablespace by

alter tablespace temp default storage(maxextents unlimited); then alter tablespace temp coalesce;

and try your query. If space is not sufficient in temp ts then message will come with ORA-1652. In that case you have to increase size of temp tablespace by resizing extisting file or adding another datafile.

Hi Gurus,

I issue the following command select count(*) from view1 and encounter the following error "ORA-01630: max # extents (121) reached in temp segment in tablespace TEMP". I think I need to increase the tablespace TEMP but how do I calculate the temporary space needed ?

Assuming view1 is "select * from table1, table2 where table1.Col1=table2.Col1"
Is the temporary space needed = (table 1 row-length * table 1 total number of rows ) * (table 2 row-length * table 2 total number of rows ) ?

Any advice ? Thanks.

Regds,
New Bee
