Running DB System Checks in CCMS (Informix) 
Use
You can use this procedure to run database system checks (shortened to "DB system checks") for your Informix database. This procedure is started from the Computing Center Management System (CCMS) in the R/3 System.
You can also run the DB system checks in the
DBA Planning Calendar or
SAPDBA.
Prerequisites
You are ready to use CCMS. Refer to
Getting Started in CCMS with Informix DBA.Procedure
The system prompts you to define the type of check you want to run.

If you want to change the configuration, see
Configuring DB System Checks in CCMS (Informix).Result
The system executes the check, normally taking only a short time.

SAP recommends that you always look at the results of check runs as soon as possible, otherwise you might fail to react in good time to a warning or error. At worst, this might lead to data loss.
For more information about checking the results, see
Viewing DB System Checks in CCMS (Informix).
