AR System Administration - Server Information form - DSO tab
Many of the DSO server configuration tasks are performed in the DSO tab in the AR System Administration: Server Information form.

Fields in DSO tab in the AR System Administration: Server Information form
Important
This form shows the local level value of the configuration. If a local value does not exist, the form displays the global level configuration. If you modify the value on this form, the local level configuration value is modified.
For example, if a configuration shows global level value and you modify the value by using this form, the local level value gets created for the configuration.
The fields in the DSO tab are described in the following table:
Field | Description |
---|---|
Source Server | Specifies the BMC Remedy AR System server for a DSO server to support when that BMC Remedy AR System server is different from the one installed with the DSO server. Use this when setting up a DSO server outside a firewall to support an BMC Remedy AR System server running behind the firewall. The corresponding BMC Remedy AR System server configuration file entry is DSO-Source-Server. See Configuring DSO for firewalls. |
Polling Interval | Specifies the interval at which the DSO server queries the distributed pending queue for pending distributed items. Enter any integer from 0 (no polling) to 3600 seconds (1 hour). The corresponding BMC Remedy AR System server configuration file entry is DSO-Main-Thread-Polling-Interval. When a polling interval is specified, the DSO server does not receive real-time signals from workflow. |
Backup Polling Interval | Specifies the interval (in seconds) at which the DSO server checks the distributed pending queue for pending distributed items. This is used only as a backup in case an issue causes the DSO server to receive no signals from workflow. Unless an issue occurs, the DSO server continues receiving real-time signals from workflow when this option is enabled. The server does not become a polling server. The value can be any integer between 15 and 7200. By default, the backup polling interval is disabled. The corresponding BMC Remedy AR System server configuration file entry is DSO-Polling-Interval. |
API Timeout Normal | Specifies the timeout (in seconds) that the DSO server applies during communication with the BMC Remedy AR System server. Enter an integer between 60 (1 minute) and 21600 (6 hours). If you enter a value out of range, the closest in-range value is used. If you do not enter a value, the system uses the default timeout (120 seconds). The corresponding BMC Remedy AR System configuration file entry is DSO-Timeout-Normal. See Configuring the RPC timeout setting. |
Cache Check Interval | Specifies the number of seconds between occurrences of these operations:
By default, this option is set to 1800 seconds (30 minutes). The maximum value is 43200 seconds (12 hours). The corresponding BMC Remedy AR System server configuration file entry is DSO-Cache-Check-Interval. See Setting the distributed mapping cache refresh interval. |
Error Retry Option | Specifies how the DSO server responds to errors. Valid values are
The corresponding BMC Remedy AR System server configuration file entry is DSO-Error-Retry-Option. |
Max Pending Records Per Query | Specifies the maximum number of records in the Distributed Pending form that DSO reads in a single database query. Valid values are
If no value is specified, the default is 1000. The corresponding BMC Remedy AR System server configuration file entry is DSO-Max-Pending-Records-Per-Query |
Mark Pending Retry | Specifies whether to set the status of items in the DSO distributed pending queue to Retry after an attempt to perform the associated operation fails. (The failure must be due to a recoverable error. Items that fail due to nonrecoverable errors are removed from the queue.) Valid values are
Note Regardless of this option's value, the pending item is still retried based on its retry configuration (see How errors affect pending items). The corresponding BMC Remedy AR System server configuration file entry is DSO-Mark-Pending-Retry-Flag. |
Placeholder Mode | When selected, disables the DSO server that was installed on the same host as the BMC Remedy AR System server. Use this when setting up a DSO server outside a firewall to support an BMC Remedy AR System server running behind a firewall. The corresponding BMC Remedy AR System server configuration file entry is DSO-Placeholder-Mode. See Configuring DSO for firewalls. |
Log Errorsto DSO Pending Errors Form | Specifies whether to log failed pending distributed operations to the Distributed Pending Errors form. The corresponding BMC Remedy AR System server configuration file entry is Log-DSO-Errors-To-Form. See Logging failed pending items. |
Suppress No Such Entry Error for Distributed Delete | Specifies whether to log BMC Remedy AR System server error 302 (entry does not exist in database) in the arerror.log file when performing distributed delete operations.
Note When this option is selected, errors caused by valid problems might also be omitted from the log. The corresponding BMC Remedy AR System server configuration file entry is DSO-Supress-No-Such-Entry-For-Delete. See Logging the ARERR 302 error during distributed deletes. |
