Problems caused by database connection Configuration

As we all know, general application software must have some system configuration work. In the daily development process, there are many similar configurations, some of which are very simple, just take a moment to set up. Some are complicated, suchOracle,A well-trained professional is required. For information management software, the most common is database configuration information files. It usually contains the user name and password of the system and the configuration of some system features. What I want to talk about is some problems caused by simple database configuration information (three items: Database Service name, user, password.

This is a common scenario in software companies: On a day, the product manager is small.MReceive the boss's instruction and inform TomMIn the afternoon, we need to go to the customer's site for a product demonstration and instruct them to make all preparations. The main task is to install the system to be demonstrated on a laptop. Small after receiving the commandMWork will be carried out immediately, because the system version on his computer is old, so small to the Development DirectorWAsk for the System Installation File. (SmallWUpgrade the product at the customer's site. The latest version is available on the customer's site, and the system has been used for nearly half a year)

SmallMAfter obtaining the installation file, there is basically no problem. In addition to the system file, there is also a system installation step description file. Small lookWIt's considerate. Subsequently smallMIt takes a lot of time and effortOracleIn terms of database configuration, he forgot the specific technical details. After all, he has not gone through the database for many years.

However, fortunately, you can complete so much work before the boss calls, And now you only have to configure the database connection. RunProgramIn the left-side navigation pane ". This familiar interface makes smallMThere is a feeling that everything is in control, but he seems to have forgotten what a philosopher said: "The Devil always appears in front of you after you fall asleep ". SmallMEnter the Database Service name, user, and password, and click Connect ". However, the system does not get as smooth as usual, but keeps popping up the "connection failure" message. SmallMMy heart was a bit flustered, and the rest of the time was not enough, and the boss kept pushing.

SmallMYou have to manually modify the file and open the program directory file, which contains3Suffixes:Ini. So many, which one should I change? (Making the configuration of an information management system as hard as the driver) Open them one by one. Two files are very similar and small.MThe two files are constantly modified, and the results are the same and cannot be connected........ The last demonstration time was reached, and the boss asked why it was not done, because the boss was constantly explaining to the customer. SmallMI had to try againCall someone for help. The boss is not in a hurry.MGo to the meeting and instruct meMSolve this problem on the way ......

I don't know the final result.MThe task can be completed successfully. ApparentlySmallMNot familiar with the product is the main reason, but the product itself has some details and problems are not well handled. The configuration files are messy, and the system installation instructions are too simple and the necessary steps are not properly described. These details are easily overlooked. A seemingly simple problem can compromise the ease of use of the product.
