Manage disk spaceYou can use several utilities and tools to manage disk spaces and the data that the database server controls.
Monitor disk usage
Monitor simple large objects in a blobspace
Monitor blobspace usage with oncheck -pe

Monitor blobspace usage with oncheck -pe

The oncheck -pe command provides information about blobspace usage:

Names of the tables that store TEXT and BYTE data, by chunk
Number of disk pages (not blobpages) used, by table
Number of free disk pages remaining, by chunk
Number of overhead pages used, by chunk

The following example shows sample oncheck -pe output.
