Proxy Manager

The SAS Management Console tree for SPD Server contains a folder called Proxy Manager. You use the Proxy Manager to display tables that list all users that access a specific SPD Server host. The current libref allocations are displayed for each user, as well as information about the proxy that serves each libref. Available proxy information includes the process ID, the port number, the library path, and if the libref was established with record locking, the thread ID. For each allocated libref, you can view every data set that is accessible to or open in the libref. If a libref was established with ACL special privileges, then all data sets in the specified domain are visible and accessible to that libref, regardless of any connection settings that are established through the SPD Management utilities in the SAS Management Console.

Before you can perform any operations in the Proxy Manager, you must be connected to an SPD Server host. The section Connecting to an SPD Server provides detailed instructions on connecting to an SPD Server host. After you connect to an SPD Server host, click Refresh Data in the Proxy Manager to update the view on the table data.

You can filter, sort, reorder, and hide Proxy Manager table columns to display proxies of interest. You perform filtering and sorting by clicking on the column headings and selecting the appropriate choice from the menu.

Filtering can be specified for any number of the columns. Column filters offer three possible states:

You can drag column headings to a new place in the table to reorder columns. To hide or reveal a column, use the blue down arrow located above the vertical scroll bar on the right side of the Proxy Manager.

Click Refresh Data to update the table with the most current proxy data. Refreshing is necessary after an initial connection or after a proxy state has been manipulated. Because a proxy's state is dynamic, each refresh provides only an instantaneous snapshot of the proxies. Data status can change immediately after the data is refreshed, which is the nature of a dynamic client/server environment. If no users are currently logged on to the server, a window displays the message.

Click Interrupt to interrupt a selected libref's proxies. The proxy's activity is halted when it next processes data from its socket. The frequency with which the proxy accesses its socket is unpredictable and can vary depending on many variables, but the proxy interrupt operation is normally the first method used to halt a proxy from accessing a given data set or domain.

Click Cancel to cancel all proxies in the selected libref. The proxy's activity is immediately halted, and any open data connections are immediately closed. Clicking Cancel to stop a proxy from accessing a data set or a given domain is recommended when the interrupt operation is unacceptably delayed.
