WebLogic Datasources : Automatically Shutdown and Start up

Question

Hi there,
I have a problem with my datasources, I have WLST script which shutdown and start automatically some datasources in my environment, all of them in my crontab !
Follow exactly my script !
[weblogic@wls_server restartDS]$ cat shutdownDS1.py | more
connect('weblogic','password','t3://server:10000')
domainConfig()
servers = cmo.getServers()
domainRuntime()
for server in servers:
try:
print 'check ' + server.getName()
print '/ServerRuntimes/' + server.getName() + '/JDBCServiceRuntime/' + server.getName() + '/JDBCDataSourceRuntimeMBeans/MYDATASOURCE-XA1'
cd('ServerRuntimes/' + server.getName() + '/JDBCServiceRuntime/' + server.getName() + '/JDBCDataSourceRuntimeMBeans/MYDATASOURCE-XA1')
objectArray = jarray.array([], java.lang.Object)
stringArray = jarray.array([], java.lang.String)
invoke('shutdown', objectArray, stringArray)
except WLSTException,e:
print server.getName() + 'is not running.'
for server in servers:
try:
print 'check ' + server.getName()
print '/ServerRuntimes/' + server.getName() + '/JDBCServiceRuntime/' + server.getName() + '/JDBCDataSourceRuntimeMBeans/MYDATASOURCE-XA2'
cd('ServerRuntimes/' + server.getName() + '/JDBCServiceRuntime/' + server.getName() + '/JDBCDataSourceRuntimeMBeans/MYDATASOURCE-XA2')
objectArray = jarray.array([], java.lang.Object)
stringArray = jarray.array([], java.lang.String)
invoke('shutdown', objectArray, stringArray)
except WLSTException,e:
print server.getName() + 'is not running.'
exit()
Don´t worry, I have another script which kill XA3 and XA4 datasources as well, so, this way, I have load balancing here !
It works with CRONTAB !
The problem here is : Doesn´t matter if datasources are running or not, simply , datasources automatically shutdown and after that, start it! But I would like to improve this, I would like to implement datasource status condition, I mean, when datasource it become overloaded, it kill automatically , this way, I would not use crontab, but another kind of trigger |!
Did you see this before ?
I would like to improve this workaround !
Just keep in mind, me and my team, didn´t discover the root cause yet, so, this automatically datasource restart is a kind of workaround!
Thanks in advance !

Hmm. what was the problem app?
Force a shut down by holding the power button for an extended amount.
Reboot into SafeBoot mode to clear cache files, then reboot as normal.
