Hi All,

We have ETL/reporting application which is supported by the same Oracle DB. At times, we face temp space error and either of the jobs get failed. Hence we have created 2 temporary tablespaces and segregated the DB accounts to have default temporary tablespace to narrow down the issue.

We would like to know the historic utilization/growth for each temporary tablespace. For example, what was the highest utilization for the temporary tablespace each day? Did it hit 90%,50% or less than that. Went through various documentations to find the query which assists in getting the current temp utilization details.

How do we get the historic report on temporary tablespace utilization when we have multiple tablespaces?

Regards,
Antony

There is no history of temp space usage, you have to build your own regularly querying v$sort_usage.

Thanks Michel. Wondering if I can leverage anything that already exists with the product.

A better choice, for your case, maybe v$sort_segment or its aggregating view DBA_TEMP_FREE_SPACE (still building you own history table from it).
