MySQL table_open_cache size unusually small

https://bugzilla.redhat.com/show_bug.cgi?id=1080547
Users do not have the ability to change table_open_cache to values other
than 4 (and have them stick).  The set value seems too low to allow
database operations to remain efficient.  For example, in my app I have
18 tables that are constantly being written to from a single persistent
connection, but can only have four tables cached at a time.  This leads
to tables having to be re-opened which causes fairly significant disk
I/O.
Both env OPENSHIFT_JBOSSEAP_MODULE_PATH and OPENSHIFT_JBOSSAS_MODULE_PATH exist in jbosseap/as

Postgresql still can be accessed via DB driver after postgresql stop
for jboss app

https://bugzilla.redhat.com/show_bug.cgi?id=1081796
Create one jboss app(e.g., myjbosseap6), embedded with postgresql-8.4 db
cartridge and add postgresql.jsp into src/main/webapp of local repo, ant
then git push. Access
http://$appname-$domainname.int.rhcloud.com/postgresql.jsp after
postgresql stop, found it still can be accessed, restart jbosseap app,
found it still works.
