1.查詢數據庫是否有等待
select * from resource_queues where node_name=(select node_name from nodes order by node_name limit 1) order by queue_entry_timestamp desc;
2.查當前數據庫執行的sql(包含在隊列里等待的)
select substr(current_statement, 1, 200), count(1)
from sessions
where not current_statement is null and (transaction_id, statement_id)<>(current_trans_id(), current_statement())
group by 1;
3.資源池
3.1查詢當前資源池的設置情況
SELECT name, memorysize, maxmemorysize, priority, runtimepriority,QUEUETIMEOUT,runtimeprioritythreshold, runtimecap, maxconcurrency
FROM V_CATALOG.RESOURCE_POOLS;
3.2查詢當前資源池的使用狀態
select node_name,pool_name,running_query_count as running,memory_size_kb,memory_inuse_kb,general_memory_borrowed_kb,query_budget_kb
from resource_pool_status
where running_query_count > 0
order by pool_name,node_name;
4.數據是否持久化到磁盤,DIFF=0
select latestepoch-earliestepoch as DIFF,epochmap,earliestepoch,latestepoch,ahmepoch from vs_epoch_map;
5.查詢Tuple Mover狀態(dbadmin執行）
select node_name,service_name,service_interval_sec as period,is_enabled,last_run_start,last_run_end
from system_services
where service_name like 'TM%'
order by last_run_end desc,last_run_start desc,service_name;
6.手動將數據持久化(Moveout)
select do_tm_task('moveout','');
7.導出建表語句
select export_objects('/tmp/all.sql','');
8.查看license信息
SELECT DISPLAY_LICENSE();
