宿主主机如何访问虚拟机中的docker服务 网上的回答不一而足,然而都没有解决,最后上了Stack Overflow,找到了答案,国内的小伙伴还得加油呀. 环境 宿主机系统 : window 8, 虚拟机软件: Oracle VirtualBox (CentOS7) docker version: 19.03.7 问题描述 虚拟机内部 systemctl start docker 启动docker , docker run -d -p 80:80 nginx 启动nginx 服务, 虚拟机ip 192.168.56.200 ,docker 服务ip 172.17.0.16 宿主机浏览器 localhost:81 无法访问nginx . 解决方法: 打开virtualbox 选择docker服务所在的虚拟机 点击设置 -> 网络 选择 NAT 网卡 点击高级 -> 端口转发 6 添加规则 : tcp 协议 ,主机和子系统端口设置,如 host:80 guest:80 浏览器访问 localhost:80 ,可以查看到nginx 界面 原文: 1.

更多精彩内容，请登录： ke.sandata.com.cn 如今已经是Oracle Database 21c的时代了，你是否还考虑过使用EXP/IMIP这些9i中的工具呢？ 其实在特殊的场景中，这些看似“老的工具”，也是可以帮助你解决棘手的问题。 比如：可以在数据库只读模式下，导出数据等。又或者将其应用在我下文中所描述的场景中。 进入正题，某客户找到我，描述了其数据库无法启动的故障，经过分析得出数据库软件被注入了恶意的代码，导致TAB$表数据被删除，从而无法启动数据库，告警日志里面的输出如下： Errors in file D:\APP\ADMINISTRATOR\diag\rdbms\xxxx\xxxx\trace\xxxx_ora_13308.trc (incident=26578): ORA-00600: 内部错误代码, 参数: [16703], [1403], [20], [], [], [], [], [], [], [], [], [] Incident details in: D:\APP\ADMINISTRATOR\diag\rdbms\xxxx\xxxx\incident\incdir_26578\xxxx_ora_13308_i26578.trc Use ADRCI or Support Workbench to package the incident.

Join elimination not working in Oracle with sub queries

问题 I am able to get join elimination to work for simple cases such as one-to-one relations, but not for slightly more complicated scenarios. Ultimately I want to try anchor modelling, but first I need to find a way around this problem. I'm using Oracle 12c Enterprise Edition Release 12.1.0.2.0. DDL for my test case: drop view product_5nf; drop table product_color cascade constraints; drop table product_price cascade constraints; drop table product cascade constraints; create table product(

Flag individuals that share common features with Oracle SQL

由 ﹥＞﹥吖頭↗ 提交于 2021-02-07 11:13:41
问题 Consider the following table: ID Feature 1 1 1 2 1 3 2 3 2 4 2 6 3 5 3 10 3 12 4 12 4 18 5 10 5 30 I would like to group the individuals based on overlapping features. If two of these groups again have overlapping features, I would consider both as one group. This process should be repeated until there are no overlapping features between groups. The result of this procedure on the table above would be: ID Feature Flag 1 1 A 1 2 A 1 3 A 2 3 A 2 4 A 2 6 A 3 5 B 3 10 B 3 12 B 4 12 B 4 18 B 5 10

Connect to DB using LDAP with python cx_Oracle

由 北战南征 提交于 2021-02-07 10:52:52
问题 I have a set of python scripts that use cx_Oracle to connect to a remote DB. This is a large project, were this connections are used several times. Additionally, I produce an .exe file that is distributed and should be as self-contained as possible. In other words, if I send you the .exe, you should be able to run it without any extra tinkering (I use pyinstaller ) Right now, I get a connection using ip = 'myhost.example.pt' port = 1521 SID = 'MYDB_PRD.EXAMPLE.PT' dsn_tns = cx_Oracle.makedsn

How to call a pl/sql anonymous block from an pl/sql anonymous block

由 荒凉一梦 提交于 2021-02-07 10:50:11
问题 I have the following PL/SQL block and it's working fine. I would like to call this function (TimeToFrame) but from another PL/SQL block. I cannot declare this function in a procedure or package that is stored in the DB. In other words how can I call a pl/sql from another pl/sql where both pl/sql are anonymous blocks?? What if I put that function in a separate .sql file. Can't I call that .sql file from my anonymous block and pass it some IN parameters and have that fct return OUT params?
