Monitoring and Viewing DRCP Settings:

To ensure optimal performance and troubleshoot any potential issues related to DRCP, it's essential to monitor and view the DRCP settings in your Oracle database. The following scripts can be used to gather valuable information about the DRCP configuration and monitor its performance:

1. Viewing DRCP Configuration: To view the current DRCP configuration settings, you can execute the following SQL query:

sql
Select * from DBA_CPOOL_INFO;

This query provides details such as the maximum number of pooled servers, session pooling mode, minimum and maximum number of sessions per pooled server, and other relevant DRCP settings.

2. Monitoring DRCP Statistics: Oracle provides dynamic performance views to monitor the DRCP statistics. The following query can be used to retrieve information about the current DRCP pool and server statistics:

sql
SELECT * FROM GV$CPOOL_CC_STATS

These views offer insights into metrics such as the number of connections created, connections in use, connections released, and other statistics related to DRCP pool and server utilization.

3. Monitoring DRCP Performance: To monitor the performance of the DRCP connections and identify potential bottlenecks, you can execute the following SQL query:

sql
SELECT * FROM GV$CPOOL_CC_STATS

This query provides valuable information about the performance metrics of the DRCP connections, including the number of requests, average response time, and connection queue length.

4. Checking DRCP Status: To check the overall status of the DRCP feature in your Oracle database, you can use the following query:

sql
select a.connection_status,a.*  from gv$cpool_conn_info a; 

The returned status can be "ENABLED" if DRCP is active or "DISABLED" if it's currently disabled.

5. Monitoring DRCP Session Activity: To monitor the activity of individual DRCP sessions and connections, you can query the v$drcp_sessions view:

sql
select sess.inst_id Inst, sess.username, sess.sid,
       sess.server,
       sess.seq#, round(sess.wait_time_micro/1000000,1) time_waited, sess.event, sess.state, sess.status,
       sess.program, sess.machine, sess.module, sess.action
  from gv$session sess
where sess.server = 'POOLED'
order by sess.sid;

This view provides details about the active DRCP sessions, including the session ID, username, client identifier, and other relevant information.

By regularly running these monitoring scripts, database administrators can gain insights into the current DRCP settings, track performance metrics, identify potential issues, and take necessary actions to optimize the performance of DRCP in their Oracle database.

Conclusion:

Monitoring and viewing the DRCP settings in Oracle is crucial for ensuring optimal performance and troubleshooting any potential issues. By utilizing the provided scripts to gather information about the DRCP configuration, monitoring statistics, and tracking performance metrics, database administrators can effectively manage and optimize the DRCP feature to enhance the performance of their Oracle database-driven applications.
