6.4.1.2 Cache Information

The Cache view is available in the Cluster Manager window if caching is enabled. The categories of information and their display sequence are controlled by the Options settings. Table 6–5 describes categories that might appear. Status The status of the object in the cluster: ■ Online. The Cluster Controller or Oracle BI Server is online. Online Cluster Controllers can accept session requests and assign them to available servers within the cluster. Online Oracle BI Servers can be assigned sessions by the Cluster Controller. ■ Quiesce. This status is applicable to clustered servers only. When a server is quiesced, any activity in progress on outstanding sessions is allowed to complete before the server transitions to Offline status. ■ Offline. The Cluster Controller or Oracle BI Server is offline. Offline Cluster Controllers cannot accept session requests or assign sessions to available servers within the cluster. Offline Oracle BI Servers do not communicate with the controlling Cluster Controller and cannot accept sessions assigned by the controlling Cluster Controller. If the server subsequently becomes available, then it is allowed to participate in the cluster. To stop the Cluster Controller or clustered server after quiescing it, issue the Stop command. ■ Forced Offline. This status applies to clustered servers only. The Oracle BI Server has been stopped. This is identical to the offline status, except that if the Oracle BI Server comes back online, it is not assigned requests. The server remains in this state until the Start command is issued against this server from the Administration Tool Cluster Manager, or both Cluster Controllers are shut down and restarted. ■ Online: Active. The Oracle BI Scheduler instance is online, running, and the one to which Oracle BI Scheduler clients connect. This instance executes jobs. ■ Online: Inactive. The Oracle BI Scheduler is online but not running. This instance is ready to take over for the active instance if the active instance becomes unavailable. ■ Online: Inactive Pending. The Oracle BI Scheduler was active and is trying to go into an inactive state. This might take a few minutes for example, if multiple jobs are running. Type When Clusters is selected in the Explorer pane, this field is available. There are three types: ■ Controller. The object is a Cluster Controller. ■ Server. The object is an Oracle BI Server. ■ Scheduler. The object is a Scheduler Server.

Shows users currently logged on to the Oracle BI Server. ■ Request window: Appears on the bottom. Shows active query requests for the user selected in the Session window. Table 6–6 describes the information that is displayed in the Session window. Table 6–7 describes the information that is displayed in the Request window. Last used Last time the result set of the cache entry satisfied a query. After an unexpected shutdown of an Oracle BI Server, the Last used time might temporarily have a stale value, that is, older than the true value. Row count Number of rows that are generated by the query. Row size Size of each row in bytes in this cache entrys result set. SQL Text of the SQL statement that generated the cache entry. Use count Number of times that this cache entrys result set has satisfied a query since Oracle BI Server startup. User Name of the user who submitted the query that resulted in the cache entry. Table 6–6 Session Window Columns Top Window Column Description Catalog Name of the Oracle BI Presentation Catalog to which the session is connected. Client Type Type of client session. The client type of Administration is reserved for the user who is logged in with the Oracle BI Administrator user ID. Last Active Time Timestamp of the last activity on the session or the query. Logon Time Timestamp when the session logged on to the Oracle BI Server. Repository Logical name of the repository to which the session is connected. Session ID Unique internal identifier that the Oracle BI Server assigns each session when the session is initiated. User Name of the user connected. Table 6–7 Request Window Columns Bottom Window Column Description Last Active Time Timestamp of the last activity on the session or the query.
