Distributed query processing (DQP) requires temporary space for use by participating multiplex nodes. This method uses the Sybase Central GUI to add temporary storage.
Adding shared temporary storage
New and freshly migrated databases contain an empty IQ_SHARED_TEMP dbspace. To enable DQP, add files to this dbspace, then make the files read-write accessible from all multiplex nodes.
All multiplex servers must be running.
From Sybase Central, connect to the coordinator.
In the folders view, double-click the DBSpaces folder. In the Dbspaces folder, double-click IQ_SHARED_TEMP. Right-click IQ_SHARED_TEMP and choose New | File.
Click Add.

Verify your selections and click OK.
Wait for the new file information to propagate to all multiplex nodes. This may take a few minutes.
Right-click IQ_SHARED_TEMP and choose Properties.
