基础命令

服务

要先切换到hana用户下

查看服务是否启动

HDB info

启动服务

HDB start

获取instance_id

su - {hana_user}
echo $TINSTANCE

数据库

连接数据库

hdbsql -u system -p 'xxxxxx' -i {instance_id}

获取数据库状态

SELECT DATABASE_NAME, ACTIVE_STATUS FROM M_DATABASES;

获取数据库的catalog记录

SELECT* FROM M_BACKUP_CATALOG;

获取最后一次备份catalog记录

SELECT ENTRY_TYPE_NAME,BACKUP_ID,COMMENT,MESSAGE FROM M_BACKUP_CATALOG WHERE (ENTRY_TYPE_NAME='complete data backup' or ENTRY_TYPE_NAME='incremental data backup' or ENTRY_TYPE_NAME='differential data backup') ORDER BY ENTRY_ID DESC LIMIT 1;

配置

获取日志归档模式

SELECT KEY,VALUE FROM M_INIFILE_CONTENTS WHERE FILE_NAME = 'global.ini' AND KEY='log_mode'

获取日志归档路径

hana1.0的日志归档目录和catalog归档目录是一样的

SELECT LAYER_NAME, SECTION, KEY, VALUE from M_INIFILE_CONTENTS where FILE_NAME='global.ini' and (key='basepath_logbackup' or key='basepath_catalogbackup');

拷贝数据备份的缓存大小

SELECT FILE_NAME,LAYER_NAME,TENANT_NAME,HOST,SECTION,KEY,VALUE FROM M_INIFILE_CONTENTS WHERE FILE_NAME = 'global.ini' AND KEY='data_backup_buffer_size';

更新数据备份的缓存大小, 不能修改DEFAULT层，那就修改SYSTEM层，优先级：SYSTEM > DEFAULT

alter system alter configuration ('global.ini', 'SYSTEM') set ('backup', 'data_backup_buffer_size') = '256' WITH RECONFIGURE;

备份

hana 1.0 备份参数中不支持添加COMMENT参数

全量备份

BACKUP DATA  USING FILE ('/mnt/data','full_');

增量备份

BACKUP DATA  INCREMENTAL USING FILE ('/mnt/data','incremental');

差异备份

BACKUP DATA  DIFFERENTIAL USING FILE ('/mnt/data','differential');

备份之后的文件：

查询正在运行中的备份

SELECT ENTRY_ID,ENTRY_TYPE_NAME,BACKUP_ID,STATE_NAME,COMMENT FROM m_backup_catalog WHERE (ENTRY_TYPE_NAME='complete data backup' OR ENTRY_TYPE_NAME='incremental data backup'  OR ENTRY_TYPE_NAME='differential data backup') AND STATE_NAME='running';

取消备份

backup cancel {backup_id}

获取数据库的catalog记录

SELECT* FROM M_BACKUP_CATALOG;

获取最后一次备份catalog记录

SELECT ENTRY_TYPE_NAME,BACKUP_ID,COMMENT,MESSAGE FROM M_BACKUP_CATALOG WHERE (ENTRY_TYPE_NAME='complete data backup' or ENTRY_TYPE_NAME='incremental data backup' or ENTRY_TYPE_NAME='differential data backup') ORDER BY ENTRY_ID DESC LIMIT 1;

删除备份记录

BACKUP CATALOG DELETE BACKUP_ID {backup_id};

暂未删除成功
