When you use the nid command to modify the Database name and dbid, you will inevitably encounter the situation where you need to modify the dbname and dbid, for example, restoring the database to the same machine is one of them. However, dbname and dbid are one of the important symbols used to identify the database, especially dbid, which is unique. Therefore, the modification should be handled with caution. This document describes how to modify dbnam
For data similar to this, if I have a variable nId, how can I traverse it and know its name. [{

Nid is a tool that Oracle has provided from 9IR2 and can be used to change the database name without having to go through the cumbersome ways of rebuilding control files before.
It should be explained that although this tool comes from 9IR2, it can still be used for oracle8i.
First look at the help:

dbnameAfter modification, you do not need to use open resetlogs to open the database. (Note that dbname is not unique, and global name is unique ).After modification, all the backups are archived logs still available.After modification, You need to modify the db_name parameter in pfile/spfile and recreate the corresponding Oracle password file.If you need to use the old control file to restore the database, you should use the pfile/spfile before modification and the password file to start the d
In some systems, the Oracle database name is not very standard. If you do not want to recreate the Oracle database, you can use the nid tool that comes with Oracle to modify the name of the Oracle database. During the entire modification process, the control file and data file are modified and the dbid is reset. We recommend that you back up the data before the modification.
In this example, the instance_name and db_name in the Oracle database are cha
Cstring: loadstring (uint NID)
Conclusion: The correct way to load string resource by ID is to call cstring: loadstring (hinstance, uint NID), specifying the DLL handler you want to search.
ProblemCstring: loadstring (uint NID) will first use the instance handle of the main application to search for a string with the given ID. failing that, it will look in DL
