1. V$TEMP_SPACE_USAGE view: This view gives details about the free house in all the momentary tablespaces within the database.
The V$TEMP_SPACE_USAGE view is a beneficial software for monitoring the free house in momentary tablespaces. This view gives details about the next:
- Non permanent tablespace title
- Whole house within the momentary tablespace
- Free house within the momentary tablespace
- Share of free house within the momentary tablespace
This info can be utilized to establish momentary tablespaces which can be working low on free house. It will also be used to trace the expansion of momentary tablespaces over time.
To question the V$TEMP_SPACE_USAGE view, you should use the next SQL assertion:
SELECT * FROM V$TEMP_SPACE_USAGE;
The output of this question can be an inventory of all the momentary tablespaces within the database, together with the free house in every tablespace.
Monitoring the free house in momentary tablespaces is a vital a part of database administration. Through the use of the V$TEMP_SPACE_USAGE view, you’ll be able to guarantee that there’s sufficient free house in momentary tablespaces to satisfy the wants of person periods and Oracle itself.
2. DBA_TEMP_FREE_SPACE view: This view gives details about the free house within the specified momentary tablespace.
The DBA_TEMP_FREE_SPACE view is a beneficial software for monitoring the free house in a specified momentary tablespace. This view gives details about the next:
- Non permanent tablespace title
- Whole house within the momentary tablespace
- Free house within the momentary tablespace
- Share of free house within the momentary tablespace
This info can be utilized to establish momentary tablespaces which can be working low on free house. It will also be used to trace the expansion of momentary tablespaces over time.
To question the DBA_TEMP_FREE_SPACE view, you should use the next SQL assertion:
SELECT * FROM DBA_TEMP_FREE_SPACE WHERE TABLESPACE_NAME = 'TEMP';
The output of this question can be an inventory of details about the desired momentary tablespace, together with the free house within the tablespace.
Monitoring the free house in momentary tablespaces is a vital a part of database administration. Through the use of the DBA_TEMP_FREE_SPACE view, you’ll be able to guarantee that there’s sufficient free house in momentary tablespaces to satisfy the wants of person periods and Oracle itself.
3. Computerized Area Administration (ASM): ASM can be utilized to robotically handle the free house in momentary tablespaces.

4. Monitoring instruments: There are a selection of monitoring instruments that can be utilized to trace the free house in momentary tablespaces.
Monitoring instruments can present a beneficial solution to monitor the free house in momentary tablespaces and could be an vital element of a complete technique for managing momentary tablespaces. These instruments can present real-time monitoring of momentary tablespace utilization, in addition to historic knowledge that can be utilized to establish developments and patterns. This info can be utilized to make sure that there’s all the time sufficient free house in momentary tablespaces to satisfy the wants of person periods and Oracle itself.
There are a selection of various monitoring instruments out there, each from Oracle and from third-party distributors. A few of the hottest monitoring instruments embody:
- Oracle Enterprise Supervisor
- SolarWinds Database Efficiency Analyzer
- Quest Highlight on Oracle
These instruments can present a wide range of options that can assist you monitor the free house in momentary tablespaces, together with:
- Actual-time monitoring of momentary tablespace utilization
- Historic knowledge on momentary tablespace utilization
- Alerts that may be triggered when momentary tablespaces are working low on free house
- Reporting and graphing capabilities
Through the use of a monitoring software to trace the free house in momentary tablespaces, you’ll be able to guarantee that there’s all the time sufficient free house to satisfy the wants of person periods and Oracle itself. This can assist to forestall errors and efficiency issues, and may assist you to establish and resolve any points that will come up with momentary tablespaces.
