Tuning RelStorage and parameters of PostgreSQL on Plone site

Does that help I got many times an error of POSKeyError. I think our setting is not enough parameters of PostgreSQL. Because the system chenged storage from MySQL to PostgreSQL. I got the error many times before the chenging. , Here are some PostgreSQL tune-ups within postgresql.conf:
# shared_buffers and effective_cache_size should be 30%-50%
# of your machine free memory

shared_buffers = 3GB
effective_cache_size = 2GB
checkpoint_segments = 64
checkpoint_timeout = 1h
max_locks_per_transaction = 512
max_pred_locks_per_transaction = 512

# If you know what you're doing you can uncomment and adjust the following values

#cpu_tuple_cost = 0.0030
#cpu_index_tuple_cost = 0.0001
#cpu_operator_cost = 0.0005
recipe = plone.recipe.zope2instance
rel-storage =
  type postgresql
  dbname datafs
  user zope
  password secret
  blob-dir /var/sharedblobstorage/blobs
  blob-cache-size 350MB
  poll-interval 0
  cache-prefix datafs

Plone site: How do I get special characters to display properly on my plone page?

Tag : python , By : Pradeep Gowda

it should still fix some issue I have a function in a view class of my content type that returns a dictionary. The dictionary contains values retrieved from a mysql backend database (uses UTF-8 encoding). , i'd convert your data to unicode to be on the safe side:
from Products.CMFPlone.utils import safe_unicode
return dict(assetID=safe_unicode(assetDetails[0]),

Configure Plone to use Relstorage as blobstorage

This might help you The solution was to use zodbconvert again. Correctly configured it can convert from one storage to another, for example from Blobstorage to Relstorage. In my case the configuration looks like that:
<filestorage source>
  path     /home/user/Plone433-dev/zeocluster/var/filestorage/Data20141230.fs
  blob-dir /home/user/Plone433-dev/zeocluster/var/blobstorage

<relstorage destination>
  shared-blob-dir false
  # ZODB Cache Dir
  blob-dir ./var/cacheblob
  blob-cache-size 10mb
    host localhost
    db Zodb
    user zodbuser
    passwd XXXXXXXXX

Plone- ComponentLookUpError is preventing me from deleting Plone site?

Tag : development , By : BooTeK

should help you out What basically prevents you from deleting your site are the events that are triggered everytime (that run your mentioned troublesome code). To prevent this behavior, I can suggest doing the following:
$ cd {buildout-dir}
$ bin/zopepy
> from transaction import commit
> app._delObject('Plone', suppress_events=True)
> commit()
