This function is used to view the volumetric elements for the tables of the database associated with a folder (current folder by default).
These elements are presented on two tabs: the first tab gives the sizing of the tables, the second tab, the sizing of the databases:
- tablespaces in the event of an Orcale database,
- the database, data and indices in the event of an Sql Server database.
This function is used, via queries on tables and views of the system, to provide technical information on the sizing of the database and the tables within. The results provided in this function should be interpreted by a database administrator, and this interpretation can depend on the version of the database used.
Presentation
It suffices to enter the name of the folder (the current folder name is proposed) and to validate the screen. By default, the current folder is proposed, but it is possible to give the name of another accessible folder, using the syntax detailed in the annex documentation.
Close
Fields
The following fields are present on this tab :
|
Define the folder code, as it is defined in the folders table, in which the work will be carried out. |
Close
Presentation
Once the folder has been given a name, the grid in the first tab is populated with the list of tables in the database and their main characteristics. Moreover the total size of the data of the folder is displayed for information purposes at the bottom of the screen.
Close
Fields
The following fields are present on this tab :
|
Name of the table where the characteristics are given. The rule is as follows :
|
|
Title associated to the previous code. |
|
Define the real number of lines in the table (to be compared with the planned number of lines). |
|
Define the number of lines expected during the dimensioning of the table. |
|
Define the total size taken by the table (in Kb). This is the sum of the data and index size. For an Oracle database, it does not include the size of the clobs, stored separately in the SYS_LOB table. |
|
This information is only displayed when the database is Oracle. It gives the number of extents in the table. |
|
This information is only displayed when the database is Oracle. It gives the number of extents in the index. |
|
Define the number of indexes create in the table. |
|
Define the size taken by the data in the table in Kb. For an Oracle database, the size of the BLOB/CLOB fields is excluded, because these fields are stored in the SYS_LOB table. |
|
Define the size (in Kb) taken by all the indexes created in the table. |
|
This information is only displayed when the database is Oracle. It gives the maximum number of extents found by index. |
|
This information is only displayed when the database is SQLServer. It gives the size (in Kb) reserved and not used for the table and its indexes. |
|
Define the number of fields (in the Adonix sense, a dimensioned field counts as one) in the table. |
|
Defining the number of columns in the table in the database. This number is in general greater that the number of fields, because an Adonix dimensioned field is counted as a field, but is defined as N columns in the database. |
|
Define the length of the record. |
|
Maximum size (in Kb) of the blobs managed in the table (when a field of this type exists in the table). |
|
When an anomaly is found in a table, the corresponding line is displayed in color (the color depends on the gravity of the anomaly). The anomalies that exist are :
These anomalies are likely to pose performance problems. |
Block number 2
|
Define the total used by the tables in the folder. |

The following elements appear in the second tab:
Close
Fields
The following fields are present on this tab :
SQL server
|
Total size of the current database, all folders included. This size includes all the data files and journal files. |
|
  |
|
Database space that has not been reserved for the database objects. |
|
  |
|
Total quantity of space allocated by the objects in the database. |
|
  |
|
Total quantity of space occupied by the data. |
|
  |
|
Total quantity of space occupied by the indexes. |
|
  |
|
Total quantity of space reserved for the objects in the database, but not yet used. |
|
  |
Grid Oracle
|
  |
|
Located in this column are the Oracle tablespaces name present to manage the data in the folder. |
|
Define the space remaining free (in Mb) in each tablespace. |
|
Define the space occupied (in Mb) in each tablespace. |

By default, the following reports are associated with this function :
PRTSCR : Screen print
This can be changed using a different setup.
In addition to the generic error messages, the following messages can appear during the entry :
The name of a folder not referenced in the folder table.
An attempt has been made to access a machine that does not exist on the network.
