Cluster Name Check |
|
| print cluster name | cemulto -n
Note: in Oracle 9i the ulity was called “cemutls” |
| print the clusterware version | cemulto -w
Note: in Oracle 9i the ulity was called “cemutls” |
|
Node Scripts |

En queues |
|
| displaying statistics | SQL> column current_utilization heading current SQL> column max_utilization heading max_usage SQL> column initial_allocation heading initial SQL> column resource_limit format a23; SQL> select * from v$resource_limit; |
|
Messaging (tickets) |
|
| ticket usage | select local_nid local, remote_nid remote, tckt_avail avail, tckt_limit limit, snd_q_len send_queue, tckt_wait waiting from v$ges_traffic_controller; |

|
Lighwork Rule and Fairness Threshold |
|
| downconvert | select cr_requests, light_works, data_requests, fairness_down_converts from v$cr_block_server;
Note: lower the _fairness_threshold if the ratio goes above 40%, set to 0 if the instance is a query only instance. |
