VM 作为ORACLE 服务器,客户端登陆提示超时,本地连接使用网络连接正常. D:>sqlplus system/oracle123@//192.168.63.121:15021/pdb01 SQL*Plus: Release 11.2.0.4.0 Production on Thu Nov 10 12:00:05 2016 Copyright (c) 1982, 2013, Oracle. All rights reserved. ERROR: ORA-12170: TNS:Connect
用户要求删除一个数据库的用户 GREENPASS,在删除的过程中,报错如下: drop user GREENPASS * ERROR at line 1: ORA-04021: timeout occurred while waiting to lock object NEWDR.HNDR_SMS_LOG 处理过程 1. 首先查询NEWDR.HNDR_SMS_LOG,这是一个'PROCEDURE': 2. 现在报错,不能对此对象进行锁定. 3. 看看什么会话在访问此对象: select B.SI
编译某存储过程 ORA-04021 timeout occurred while waiting to lock object stringstringstringstringstring Cause: While waiting to lock a library object, a timeout is occurred. Action: Retry the operation later. 查找是否有用户类型的锁,即 TM DML排队 TX
前些天某个SQL Server数据库的错误日志爆出如下错误: Timeout occurred while waiting for latch: class 'ACCESS_METHODS_DATASET_PARENT', id 00000009A5670C58, type 4, Task 0x0000000B655BC508 : 188, waittime 300, flags 0x1a, owning task 0x00000000170DC748. Continuing to wait.
今天发现线上数据库主从延迟严重: SELECT ag.name AS ag_name, ar.replica_server_name AS ag_replica_server, dr_state.database_id as database_id, dr_state.redo_queue_size, is_ag_replica_local = CASE THEN N'LOCAL' ELSE 'REMOTE' END , ag_replica_role = CASE WHEN ar_state.
ConnectionString 类似于 OLE DB 连接字符串,但并不相同.与 OLE DB 或 ADO 不同,如果“Persist Security Info”值设置为 false(默认值),则返回的连接字符串与用户设置的 ConnectionString 相同但去除了安全信息.除非将“Persist Security Info”设置为 true,否则,SQL Server .NET Framework 数据提供程序将不会保持,也不会返回连接字符串中的密码. 可以使用 Connection
某个应用正在锁定该表或者包 表为 select b.SID,b.SERIAL#,c.SQL_TEXT from v$locked_object a, v$session b, v$sqlarea c where a.SESSION_ID = b.SID and b.SQL_ADDRESS = c.ADDRESS and c.sql_text like '%table_name%' 包为 select B.SID,b.USERNAME,b.MACHINE FROM V$ACCESS A, V$SE
检查之后均没有什么太大的问题, 最后发现出现77这种错误码,有一种可能就是系统的ca包没有更新 包名为 ca-certificates 使用命令 yum install ca-certificates curl call error(77): Problem with the SSL CA cert (path? access rights?)
