How To Fix DB6103 - Buffer pool configuration

SAP Error Message - Details

• Message type: E = Error

• Message class: DB6 - DB6: Alert Monitoring and Alert Configuration

• Message number: 103

• Message text: Buffer pool configuration

What causes this issue?

You can set the size of the buffer pool in the following ways:
You set the size when creating the pool
You set a new value for the size with the command ALTER BUFFERPOOL
You use the standard value (database configuration parameter BUFFPAGE).

System Response

This message should be seen purely as a note that the relevant buffer
pool was created without a size being explicitly specified.

How to fix this error?

If you accidentally failed to set the value, you can set it with the
command ALTER BUFFERPOOL. The value will take effect as soon as you
have restarted the database. Note that the increased demand for virtual
memory causes more paging, if there is not enough real main memory
available.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
