Linux First Install oracle Start Error [How to Solve]

The following error occurs when installing Oracle for the first time:

[oracle@localhost db_1]$ ./runInstaller
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyi                                               nfo exist under PATH variable.

No X11 DISPLAY variable was set, but this program performed an operation which requires it.

Solution:

[oracle@localhost db_1]$ export DISPLAY=:0
[oracle@localhost db_1]$ echo $DISPLAY
:0

After execution, the following problems occur:

[oracle@localhost db_1]$ ./runInstaller
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyi                                               nfo exist under PATH variable.

PHP artisan cache: clear command reports an error

Use the clear cache command when building projects with laravel version 5.7 or above:

php artisan cache:clear  

Sometimes, the following errors are reported:

“Failed to clear cache. Make sure you have the appropriate permissions”

The reason is that there are two directories. You need to create a new directory.

mkdir -p storage/framework/cache/data

You also need to set directory permissions  

chmod 777 /home/www/dir/bootstrap/cache && amp; chmod 777 /home/www/dir/bootstrap/cache/*

“Failed to clear cache. Make sure you have the appropriate permissions” in Laravel 5.7_ Yang level blog – CSDN blog

Sqoop exports hive data to MySQL Error [How to Solve]

The following error is reported when exporting hive data from sqoop to MySQL

Export job failed!

	at org.apache.sqoop.Sqoop.runTool(Sqoop.java:243)
	at org.apache.sqoop.Sqoop.main(Sqoop.java:252)

This problem is caused by the field type problem or table structure problem between MySQL and hive (the fields are different or the table structure is different).

Solution: modify the type in MySQL table to be the same as that in hive table or modify the table structure

[Solved] JPA sett in parameter error: Java.lang.illegalargumentexception

[error]

Java.lang.illegalargumentexception: encrypted array valued parameter binding, but was expecting [java.lang.string (n/a)]
JPA user-defined query statement fills the placeholder of in() with parameter value, and an error is reported

[reason]

The parameter value I passed in is of array type, but the in parameter value of JPA does not support array

[solution]

When setting the in parameter, the passed in parameter must be of type list.
