1.查询数据库是否有等待
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.查当前数据库执行的sql(包含在队列里等待的)
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.资源池
3.1查询当前资源池的设置情况
SELECT name, memorysize, maxmemorysize, priority, runtimepriority,QUEUETIMEOUT,runtimeprioritythreshold, runtimecap, maxconcurrency FROM V_CATALOG.RESOURCE_POOLS;
3.2查询当前资源池的使用状态
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.数据是否持久化到磁盘,DIFF=0
select latestepoch-earliestepoch as DIFF,epochmap,earliestepoch,latestepoch,ahmepoch from vs_epoch_map;
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;
select do_tm_task(‘moveout‘,‘‘);
7.导出建表语句
select export_objects(‘/tmp/all.sql‘,‘‘);
8.查看license信息
SELECT DISPLAY_LICENSE();
