How To Fix DBMAN251 - Due to cube &1 being locked, query cannot be executed at the moment

DBMAN251 - Overview

• Message type: E = Error

• Message class: DBMAN - Data Manager Message Class

• Message number: 251

• Message text: Due to cube &1 being locked, query cannot be executed at the moment

What causes this issue?

The query cannot currently be executed, as there is an exclusive lock on
the InfoCube. This lock can originate from a compression run, a change
run, or selective deletion.

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

<ZU>For NetWeaver systems with an Oracle database system:</>
If a compression run is currently active, this error can still occur
despite the consistent read feature of Oracle if the E and F tables are
read with different logically-related accesses and the compressor
executed a database commit between the start of the first and the end of
the second access.
For normal queries, the read is automatically repeated. This can be
avoided by the fact that E and F tables are no longer read with separate
accesses. To do this, the RSADMIN parameter USE_FACTVIEW must be set to
'ALWAYS'. However, this can have a negative impact on performance.

System Response

How to fix this error?

Check whether a compression run or other change run is active. Wait
until the action has completed and start the query again.
