caching - Is it safe to truncate these table (cache_hash, cache_pages, index_rel, ...) in Typo3 4.4 / 4.5 -

-

i wonder if it's safe truncate following tables.

cache_hash cache_pages index_rel index_fulltext index_phash sys_log tx_realurl_chashcache tx_realurl_errorlog

i can't seem find reliable info on web. lowlevel cleaner didn't find clean.

thanks advice!

yes, remind clearing indexsearch , realurl cache leads higher pageload on each page @ first hit.
