hi I have a 4 client ZEO cluster that I am setting up a central sessions storage for. I'm wondering if someone can give me a little feedback on what I have done, eg i have a few questions: 1. am i doing this right? 2. where does the mapping storage store itself on the filesystem? as part of the Data.fs of the root-mounted filestorage? 3. If i add a transient object container a level below the zope root, will its data also get stored in the Mapping Storage? I am using MappingStorage and it is setup in zeo.conf like this: <mappingstorage sess> name mapping storage for sessions </mappingstorage> in zope.conf I have the temporary storage setup like this: <zodb_db temporary> <zeoclient> server 192.168.1.4:8424 storage sess name temporary mapping storage for sessioning </zeoclient> mount-point /temp_folder container-class Products.TemporaryFolder.TemporaryContainer </zodb_db> in zeo.log I get this: 2004-05-04T14:21:51 INFO(0) RUNSVR opening storage 'sess' using MappingStorage ------ 2004-05-04T14:21:51 INFO(0) ZSS:7175 StorageServer created RW with storages: 1:RW:/path/to/zeohome/var/Data.fs, sess:RW:mapping storage for sessions and later this: 2004-05-04T14:46:13 INFO(0) zrpc-conn:192.168.1.4:60202 zeoLoad() raised exception: '\x00\x00\x00\x00\x00\x00\x00\x00' Traceback (most recent call last): File "/usr/local/zope/270/lib/python/ZEO/zrpc/connection.py", line 264, in handle_request ret = meth(*args) File "/usr/local/zope/270/lib/python/ZEO/StorageServer.py", line 248, in zeoLoad p, s = self.storage.load(oid, '') File "/usr/local/zope/270/lib/python/ZODB/MappingStorage.py", line 56, in load p = self._index[oid] KeyError: '\x00\x00\x00\x00\x00\x00\x00\x00' the client connects fine, under Control Panel > Databases > temporary I see: Database Location temporary mapping storage for sessioning (connected) Database Size 239.0K also there are many writes and few loads. tia <--> george donnelly ~ http://www.zettai.net/ ~ "Quality Zope Hosting" Shared and Dedicated Zope Hosting ~ Zope Servers ~ Zope Websites Yahoo, AIM: zettainet ~ ICQ: 51907738 ~ Sales (USA): 1-866-967-3669
