Changes affected logical server policy options in SAP Sybase IQ 16.0.
| Option | Description |
|---|---|
| DQP_ENABLED |
New option. When set to 0, query processing is not distributed. When set to 1 (the default), query processing is distributed as long as a writable shared temporary file exists. When set to 2, query processing is distributed over the network, and the shared temporary store is not used. |
| LOGIN_REDIRECTION | New option. When ON, enables login redirection for logical servers governed by specified login policy. When OFF (the default), disables login redirection. |
| REDIRECTION_WAITERS_THRESHOLD | New option. Specifies the number of connections that can queue before SAP Sybase IQ redirects a connection to this logical server. Can be any integer value (defaults to 5). |
| TEMP_DATA_IN_SHARED_TEMP | When ON, all temporary table data and eligible scratch data writes to the shared temporary store, provided that the shared temporary store has at least one read-write file added. You must restart all multiplex nodes after setting this option or after adding a read-write file to the shared temporary store. (If the shared temporary store contains no read-write file, or if you do not restart nodes, data instead writes to IQ_SYSTEM_TEMP.) When OFF (the default), all temporary table data and scratch data writes to the local temporary store. |
