Setting Devspace Parameters 

Use

It is preferable that you extend an existing database instance using the command db_adddevspace (Adding a Devspace).

Use the command param_adddevspace described here only when asked to do so by Support. Inconsistencies in the devspace settings can lead to damage to the database instance.

Use this command to enter the devspace parameters in the parameter file. The new parameter value is registered by the system, and is transferred to the parameter file as the effective value when the database instance is restarted.

You set devspace parameters in two steps:

1. Change the entries for the parameters in the parameter file

2. Transfer the corresponding information to the database kernel using a utility command (Transferring a Utility Command)

If this utility command fails, you must also remove the entries in the parameter file.

No check is made of whether there is sufficient disk capacity available to add devspace.

No check is made of whether the database instance is working in mirrored (DUAL) mode for the relevant devspace.

Prerequisites

You have the DBM operator authorization ParamFull.
