See a group of people asked the ordinary user access to the base table problem, the test is as follows:The x$ base table can be accessed by creating a view, and then creating a synonym, authorization, and access to the base table for ordinary users.Of course, ordinary users visit the base table is not reasonable, theoretically not necessary, permission control should also be disallowed. It is not considered reasonable here to experiment on this issue.
colleagues can query the data in the table, but when truncate this table hold ORA-00942: The table or view does not exist
The beginning thought is the table name writes has the question, but later discovered that he deletes is not the table, but is a synonym (synonym)
It is not possible to use truncat for synonyms synonym.

One solution is to create a synonym for some tables or views on the Project database server based on the customer's critical data server. Let me introduce the process I made in the project based on how the remote server view creates syno

How to solve this problem? The most straightforward way is to allow users to access the site only through the domain name, not through the IP to directly access. This can be implemented by modifying the Apache configuration file httpd.conf. Here is the implementation of a small station:Namevirtualhost 121.*.*.*The first part of the code is to implement any access request that denies the IP directly through 121.*.*.*, and if you use 1
