發布時間：2023/12/9 数据库 29 豆豆

生活随笔收集整理的這篇文章主要介紹了 gbase导入sql文件_GBase数据库——常用命令小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

1數據庫操作與維護

1.1數據庫啟停

[root@OMMB-66-V10-001 ~]# service gcware stop

Stopping GCMonit success!

Signaling GCRECOVER (gcrecover) to terminate: [ OK ]

Waiting for gcrecover services to unload:.....[ OK ]

Signaling GCSYNC (gc_sync_server) to terminate: [ OK ]

Waiting for gc_sync_server services to unload:.[ OK ]

Signaling GCLUSTERD to terminate: [ OK ]

Waiting for gclusterd services to unload:.........[ OK ]

Signaling GBASED to terminate: [ OK ]

Waiting for gbased services to unload:^[[A.........[ OK ]

Signaling GCWARE (gcware) to terminate: [ OK ]

Waiting for gcware services to unload:.[ OK ]

[root@OMMB-66-V10-001 ~]# service gcware start

Starting GCWARE (gcwexec): [ OK ]

Starting GCMonit success!

Starting GBASED : [ OK ]

Starting GCLUSTERD : [ OK ]

Starting GCSYNC : [ OK ]

Starting GCRECOVER : [ OK ]

[root@OMMB-66-V10-001 ~]# service gcware restart

1.2集群狀態查詢

[root@zdc3 zdcapp3]# gcadmin

CLUSTER STATE: ACTIVE

CLUSTER MODE: NORMAL

===============================================================

| GBASE COORDINATOR CLUSTER INFORMATION |

===============================================================

---------------------------------------------------------------

---------------------------------------------------------------

---------------------------------------------------------------

---------------------------------------------------------------

===========================================================

| GBASE DATA CLUSTER INFORMATION |

===========================================================

-----------------------------------------------------------

-----------------------------------------------------------

-----------------------------------------------------------

-----------------------------------------------------------

1.3進程狀態查詢

[root@zdc2 gbase]# service gcware status

corosync (pid 3157) is running...

gclusterd (pid 3966) is running...

gcrecover (pid 4194) is running...

gbased (pid 3271) is running...

gc_sync_server (pid 3920) is running...

1.4GBase進程名

GBase協調節點/Coordinator node:

gcluster進程名 : gclusterd

gcware進程名 : corosync

自動回復進程名 : gcrecover

GBase數據節點/Data node

gnode進程名 : gbased

syncserver進程名 : gcsync

監控工具： gcmonit / gcmmonit

2.數據庫訪問、信息查詢

2.1命令行方式訪問數據庫

root、gbase用戶本地訪問

[root@zdc2 installGBase_v14.1]# gccli

gbase>

非本地訪問

[gbase@zdc2 ~]$ gccli -ugbase -pgbase20110531 -P5258 -h10.92.250.252

gbase>

如果需要直接訪問gnode，查詢gnode相關內容，請使用gncli命令

直接執行sql

gccli -ugbase -ppassword -P5258 -h10.92.250.252 -vvv

2.2查詢數據庫節點，副本情況

gbase> show nodes;

+------------+-----------------+-------+--------------+----------------+--------+-----------+

+------------+-----------------+-------+--------------+----------------+--------+-----------+

| 4210731200 | 192.168.250.250 | node1 | n1 | n3 | online | 0 |

| 4227508416 | 192.168.250.251 | node2 | n2 | n1 | online | 0 |

| 4244285632 | 192.168.250.252 | node3 | n3 | n2 | online | 0 |

+------------+-----------------+-------+--------------+----------------+--------+-----------+

3 rows in set (Elapsed: 00:00:00.01)

2.3數據庫版本查詢

gbase> select @@version;

+-------------------+

| @@version |

+-------------------+

| 8.6.2.20-R1.84277 |

+-------------------+

1 row in set (Elapsed: 00:00:00.01)

2.4數據庫參數查詢與設置

gbase> show variables like ‘%heap%‘;

+---------------------------+-----------+

| Variable_name | Value |

+---------------------------+-----------+

| _gbase_enable_system_heap | OFF |

| gbase_heap_data | 536870912 |

| gbase_heap_large | 268435456 |

| gbase_heap_temp | 268435456 |

| max_heap_table_size | 16777216 |

+---------------------------+-----------+

5 rows in set (Elapsed: 00:00:00.00)

gbase> set global gcluster_max_conn_in_pool=301; 全局參數

Query OK, 0 rows affected (Elapsed: 00:00:00.08)

SET [GLOBAL | SESSION] = value

丼例：開啟本節點的trace日志，默認是設置session 變量。

SET gbase_sql_trace =on;

2.5加載數據文件

load data infile ‘ftp://gbase:gbase@disp_server//opt/1.txt,ftp://gbase:gbase@disp_server//opt/2.txt‘ into table test.tablename data_format 3 fields terminated by ‘#‘ table_fields ‘FIELD1,FIELD2,FIELD3‘ datetime format ‘%Y-%m-%d %H:%i:%S‘

文件名中的#要用%23代替。

2.6常用的show語句

show databases;

--查看系統中數據庫名的語句(根據權限顯示)

show tables;

--列出給定數據庫的所有非臨時表

desc test.t;

--查看test庫t表的列信息

show index from test.t;

--查看test庫t表的索引信息

show create table test.t;

--查看test的建庫語句

showcreateprocedurep_demo;

--查看創建存儲過程的語句

顯示警告或錯誤信息：

SHOW WARNINGS; --顯示由最后一個語句產生的錯誤，警告和注意信息。

SHOW ERRORS; --顯示由最后一個語句產生的錯誤信息。

顯示集群中節點信息：

SHOW NODES; --如果有SUPER 權限，可以看到所有節點信息。

SHOW LOCAL NODE; --顯示集群中客戶端正在訪問節點的信息。

3.數據庫故障定位

3.1查看錯誤日志

[root@zdc2 gbase]# gcadmin showddlevent 查看DDL語句錯誤日志

Event count:0

[root@zdc2 gbase]# gcadmin showdmlevent 查看DML語句錯誤日志

Event count:0

[root@zdc2 gbase]# gcadmin showdmlstorageevent 查看表數據損壞日志

Event count:0

3.2查看數據庫鎖情況

[root@zdc2 gbase]# gcadmin showlock

+===============================================+

| GCLUSTER LOCK |

+===============================================+

+---------+-----+-------+-----------+------+----+

+---------+-----+-------+-----------+------+----+

Total : 0

gbase> show processlist; 查看當前正在執行的gbase進程，如果有上鎖的語句的話會打出語句

+-------+-----------------+-----------------------+---------+---------+-------+-----------------------------+------------------+

+-------+-----------------+-----------------------+---------+---------+-------+-----------------------------+------------------+

| 46247 | root | 192.168.250.250:58468 | dap_etl | Sleep | 1 | | NULL |

| 47119 | root | 192.168.250.250:9318 | dap_etl | Sleep | 27 | | NULL |

+-------+-----------------+-----------------------+---------+---------+-------+-----------------------------+------------------+

4 rows in set (Elapsed: 00:00:00.00)
