I did change my config.xml to
<Context antiJARLocking="true" path="/myApp">
<Resource auth="Container"
driverClassName="oracle.jdbc.driver.OracleDriver"
maxActive="20"
maxIdle="10"
maxWait="-1"
name="jdbc/myName"
password="myPassword"
testOnBorrow="true"
type="javax.sql.DataSource"
url="jdbc:oracle:thin:@//localhost:8080/MYDBS"
username="myUsername"
validationQuery="SELECT 1 FROM DUAL" />
</Context>
And this morning when DB restart I had to restart the tomcat to get
connection. What can be other solutions?

Well, you can use validationQuery parameter with "SELECT 1 FROM
DUAL;".
+1
Try adding validationQuery="SELECT 1 FROM DUAL" and testOnBorrow="true".
When you restart the DB, it's going to disconnect all of the connections
in your pool. If you add a validation query and one of the "testOn*"
options (testOnBorrow is my personal favorite) then the pool will catch
the bad connections, remove them and assuming your DB is back online,
create new ones.
