Deleted cached files in the app / cache folder with fatal errors

HI
Today deleted the app / cache folder in the cache file, a fatal error, the log did not appear the cause of the error.

Can the cache file be deleted?

The browser appears：
Fatal error: Uncaught RuntimeException: in /www/vendor/oro/platform/src/Oro/Bundle/EntityExtendBundle/OroEntityExtendBundle.php on line 134

Please help
Thank you

Hi cnnewin,

Yes, you right the folder app/cache is required for the application, it is default cache folder for all ORO products so it MUST be available and writable (same for app/logs folder). But all content of this folder (app/cache/*) is generated during application cache warm-up, so it can be safely deleted. However I don’t recommend you do it manually. We have special command for it:

Shell

php app/console cache:clear --env=prod

1	php app/console cache:clear --env=prod

This command safely clean cache for prod environment if you want erase cache for other environments like dev or test, just replace –env=prod with –env=dev or –env=test respectively.

P.S. In order to detect such problems (missing folders or extensions) we have special script app/oro-check.php which can detect and print found issues (so if everything is fine it will print nothing), run it to see other issues:

Shell

php app/oro-check.php

1	php app/oro-check.php

If you still have any questions I’ll be happy to answer.

Hi Vladyslav Byndych
Thank you very much for your answer,
I reinstalled the system.

But I have a new problem, e-mail synchronization can not be synchronized, I use this command:

PHP

*/1 * * * * /www/server/php/70/bin/php /www/wwwroot/app/console oro:message-queue:consume --env=prod > /dev/null

1	*/1 * * * * /www/server/php/70/bin/php /www/wwwroot/app/console oro:message-queue:consume --env=prod > /dev/null

An error occurred:
[2017-09-30 16:57:20] app.ERROR: Consume messages command exception. “Expected numeric content. content:””” {“exception”:”[object] (LogicException(code: 0): Expected numeric content. content:\”\” at /www/wwwroot/vendor/oro/platform/src/Oro/Component/MessageQueue/Consumption/Dbal/DbalPidFileManager.php:89)”} []
[2017-09-30 16:57:20] console.ERROR: An error occurred while running command “‘oro:message-queue:consume’ –env prod”. Expected numeric content. content:”” {“exit_code”:0,”arguments”:{“command”:”oro:message-queue:consume”},”options”:{“env”:”prod”}} []

Thank you for your help
