Duplicate problem with non standard cache sizes

Today I had a problem creating a standby database. Just after RMAN shutdowns and restarts the standby for copying the files, I was getting:

RMAN-05501: aborting duplication of target database
RMAN-03015: error occurred in stored script Memory Script
RMAN-04014: startup failed: ORA-04031: unable to allocate 4128 bytes of sha
red memory (“shared pool”,”unknown object”,”sga heap(1,0)”,”object queue ha
sh buckets”)

After investigating the problem was because I was decreasing the size of SGA on the target database (and putting it on Automatic Memory Management) but not decreasing the non-standard cache settings.
The solution was to add to the duplicate command the decrease of the non-standard cache (on the source it is 800M):
  SET memory_target ‘1G’
  SET db_32k_cache_size ’50M’

Find Facebook rss feed without Facebook account

I belong to the group of people who does not have a Facebook account. However, unfortunately, several companies now do only publish information on their Facebook wall.

I’m already happy that most of them have their wall public, so I can check it without account. But in some cases I would like to follow the company wall with Google Reader.

So, to find the good RSS feed to subscribe, you need first to find the Facebook id of the account you want to follow. This information you can find from the like button of that company. The like button sends you to an address like:

So the RSS feed to subscribe is:

Hope that helps someone that, like me, doesn’t have a Facebook account.
