AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
System administrationThese topics contain concepts, procedures, and reference information for database and database server administrators to use for managing and tuning HCL OneDB™ database servers.
Administrator's GuideThe HCL OneDB™ Administrator's Guide provides the information required to administer HCL OneDB™.
Disk, memory, and process management
Manage disk spaceYou can use several utilities and tools to manage disk spaces and the data that the database server controls.
Automatic space managementYou can configure the server to add more storage space automatically when more space is required. You use space more effectively and ensure that space is allocated as necessary, while reducing out-of-space errors. You reduce the time required to manually monitor your spaces to determine which storage space might run out of free space. If you configure the server to automatically add space, you can also manually expand a space or extend a chunk.
Changing the threshold and wait time for the automatic addition of more spaceWhile OneDB can react to out-of-space conditions by automatically extending or adding chunks when a storage space is full, you can also configure the server to extend or add chunks before a storage space is full.

Changing the threshold and wait time for the automatic addition of more space

While OneDB can react to out-of-space conditions by automatically extending or adding chunks when a storage space is full, you can also configure the server to extend or add chunks before a storage space is full.

About this task

Specify a threshold for the minimum amount of free KB in a storage space to trigger a task that expands the space.

You can also use the SP_WAITTIME configuration parameter to specify the maximum number of seconds that a thread waits for a space to expand before returning an out-of-space error.

To change the threshold and wait time:

Procedure

Change the value of the threshold specified in the SP_THRESHOLD configuration parameter from 0 (disabled) to a non-zero value. Specify a value from either 1 to 50 for a percentage of a value from 1000 to the maximum size of a chunk in KB.
Change the value of the SP_WAITTIME configuration parameter, which specifies the maximum number of seconds that a thread waits for a space to expand before returning an out-of-space error.
