【产品名称】社区版
【产品版本】3.1.0
【问题描述】安装完oceanbase社区版，并alter system bootstrap server_list_info后，发现社区版有一个SYS库，这个库中的表或视图都是不可访问的，会出现报错，如下：
mysql> select * from ALL_VIRTUAL_SQL_AUDIT limit 1;
ERROR 1491 (HY000): The PARTITION function returns the wrong type
mysql> select * from ALL_ALL_TABLES limit 1;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your OceanBase version for the right syntax to use near 'VARCHAR2(128)) AS OWNER, CAST(t.table_name AS VARCHAR2(128)) AS TABLE_NAME, ’ at line 1
另一方面，在oceanbase库中，也有同名表或视图，不同处已用红色标记：
mysql> show create table sys.V$SSTABLE\G
*************************** 1. row ***************************

Create View: CREATE VIEW `V$SSTABLE` AS SELECT M.TABLE_TYPE, M.TABLE_ID, T.TABLE_NAME, T.TENANT_ID, M.PARTITION_ID, M.INDEX_ID, M.BASE_VERSION, M.MULTI_VERSION_START, M.SNAPSHOT_VERSION, M.START_LOG_ID, M.END_LOG_ID, M.MAX_LOG_ID, M.VERSION, M.LOGICAL_DATA_VERSION, M.“SIZE”, M.IS_ACTIVE, M.REF, M.WRITE_REF, M.TRX_COUNT, M.PENDING_LOG_PERSISTING_ROW_CNT, M.UPPER_TRANS_VERSION, M.CONTAIN_UNCOMMITTED_ROW FROM SYS.ALL_VIRTUAL_TABLE_MGR_AGENT M JOIN SYS.ALL_VIRTUAL_TABLE_REAL_AGENT T ON M.TABLE_ID = T.TABLE_ID AND T.TENANT_ID = EFFECTIVE_TENANT_ID() WHERE M.SVR_IP=HOST_IP() AND M.SVR_PORT=RPC_PORT() AND T.TENANT_ID = SYS_CONTEXT(‘USERENV’, ‘CON_ID’)

mysql> show create table oceanbase.V$SSTABLE\G
*************************** 1. row ***************************
View: v$sstable
Create View: CREATE VIEW `v$sstable` AS SELECT M.TABLE_TYPE, M.TABLE_ID, T.TABLE_NAME, T.TENANT_ID, M.PARTITION_ID, M.INDEX_ID, M.BASE_VERSION, M.MULTI_VERSION_START, M.SNAPSHOT_VERSION, M.START_LOG_TS, M.END_LOG_TS, M.MAX_LOG_TS, M.VERSION, M.LOGICAL_DATA_VERSION, M.SIZE, M.IS_ACTIVE, M.REF, M.WRITE_REF, M.TRX_COUNT, M.PENDING_LOG_PERSISTING_ROW_CNT, M.UPPER_TRANS_VERSION, M.CONTAIN_UNCOMMITTED_ROW FROM oceanbase.__all_virtual_table_mgr M JOIN oceanbase.__all_virtual_table T ON M.TABLE_ID = T.TABLE_ID WHERE M.SVR_IP=HOST_IP() AND M.SVR_PORT=RPC_PORT() AND effective_tenant_id() = 1 OR T.tenant_id = effective_tenant_id()

请问这个库有什么作用吗
