Wait Event Histogram
- Units for Total Waits column: K is 1000, M is 1000000, G is 1000000000
- Units for % of Total Waits: us is microseconds
- % of Total Waits: value of .0 indicates value was <.05%; value of null is truly 0
- Ordered by Event (idle events last)

BEGIN :1 := orderentry.neworder(:2 ,:3 ,:4 ); END; Finding 2: Undersized SGA Impact is 6,42 active sessions, 74,67% of total activity. --------------------------------------------------------- The SGA was inadequately sized, causing additional I/O or hard parses. The value of parameter "sga_target" was "18048 M" during the analysis period. Recommendation 1: Database Configuration Estimated benefit is 5,64 active sessions, 65,61% of total activity. -------------------------------------------------------------------- Action Increase the size of the SGA by setting the parameter "sga_target" to 20304 M. Symptoms That Led to the Finding: --------------------------------- Wait class "User I/O" was consuming significant database time. Impact is 7,74 active sessions, 90,13% of total activity. Finding 3: Top Segments by "User I/O" and "Cluster" Impact is 1,63 active sessions, 18,99% of total activity. --------------------------------------------------------- Individual database segments responsible for significant "User I/O" and "Cluster" waits were found. Recommendation 1: Segment Tuning Estimated benefit is ,48 active sessions, 5,57% of total activity. ------------------------------------------------------------------ Action Investigate application logic involving I/O on INDEX "SOE.ORD_SALES_REP_IX" with object ID 74330. Related Object Database object with ID 74330. Action Look at the "Top SQL Statements" finding for SQL statements consuming significant I/O on this segment. For example, the SELECT statement with SQL_ID "29qp10usqkqh0" is responsible for 100% of "User I/O" and "Cluster" waits for this segment. Recommendation 2: Segment Tuning Estimated benefit is ,38 active sessions, 4,42% of total activity. ------------------------------------------------------------------ Action Investigate application logic involving I/O on INDEX "SOE.ORD_WAREHOUSE_IX" with object ID 74333. Related Object Database object with ID 74333. Action Look at the "Top SQL Statements" finding for SQL statements consuming significant I/O on this segment. For example, the SELECT statement with SQL_ID "gkxxkghxubh1a" is responsible for 69% of "User I/O" and "Cluster" waits for this segment. Recommendation 3: Segment Tuning Estimated benefit is ,27 active sessions, 3,11% of total activity. ------------------------------------------------------------------ Action Investigate application logic involving I/O on TABLE PARTITION "SOE.ORDERS.SYS_P552" with object ID 74012. Related Object Database object with ID 74012. Rationale The I/O usage statistics for the object are: 0 full object scans, 155039 physical reads, 56 physical writes and 0 direct reads. Recommendation 4: Segment Tuning Estimated benefit is ,25 active sessions, 2,95% of total activity. ------------------------------------------------------------------ Action Investigate application logic involving I/O on TABLE PARTITION "SOE.ORDERS.SYS_P557" with object ID 74017. Related Object Database object with ID 74017. Rationale The I/O usage statistics for the object are: 0 full object scans, 153860 physical reads, 48 physical writes and 0 direct reads. Recommendation 5: Segment Tuning Estimated benefit is ,25 active sessions, 2,95% of total activity. ------------------------------------------------------------------ Action Investigate application logic involving I/O on TABLE PARTITION "SOE.ORDERS.SYS_P573" with object ID 74033.

Symptoms That Led to the Finding: --------------------------------- Wait class "User I/O" was consuming significant database time. Impact is 7,74 active sessions, 90,13% of total activity. Finding 4: Global Cache Congestion Impact is ,15 active sessions, 1,7% of total activity. ------------------------------------------------------ Global Cache Service Processes (LMSn) in other instances were not processing requests fast enough. Recommendation 1: Database Configuration Estimated benefit is ,15 active sessions, 1,7% of total activity. ----------------------------------------------------------------- Action Increase throughput of the Global Cache Service (LMSn) processes. Increase the number of Global Cache Service processes by increasing the value of the parameter "gcs_server_processes". Alternatively, if the host is CPU bound consider increasing the OS priority of the Global Cache Service processes. Rationale The value of parameter "gcs_server_processes" was "2" during the analysis period. Symptoms That Led to the Finding: --------------------------------- Inter-instance messaging was consuming significant database time on this instance. Impact is ,46 active sessions, 5,3% of total activity. Wait class "Cluster" was consuming significant database time. Impact is ,46 active sessions, 5,3% of total activity. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Additional Information ---------------------- Miscellaneous Information ------------------------- Wait class "Application" was not consuming significant database time. Wait class "Commit" was not consuming significant database time. Wait class "Concurrency" was not consuming significant database time. Wait class "Configuration" was not consuming significant database time. CPU was not a bottleneck for the instance. Wait class "Network" was not consuming significant database time. The network latency of the cluster interconnect was within acceptable limits of 1 milliseconds. Session connect and disconnect calls were not consuming significant database time. Hard parsing of SQL statements was not consuming significant database time. The database's maintenance windows were active during 100% of the analysis period.

Interconnect Statistics
Back to TopInterconnect Ping Latency Statistics
- Ping latency of the roundtrip of a message from this instance to
- target instances.
- The target instance is identified by an instance number.
- Average and standard deviation of ping latency is given in microseconds
- for message sizes of 500 bytes and 8K.
- Note that latency of a message from the instance to itself is used as
- control, since message latency can include wait for CPU
Target Instance | 500B Ping Count | Avg Latency 500B msg | Stddev 500B msg | 8K Ping Count | Avg Latency 8K msg | Stddev 8K msg |
