Bug ID: 61307
Summary: DBpool issue when upgrade from Tomcat6 to tomcat8.0.32
Product: Tomcat 8
Version: 8.0.32
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: avi13021...@gmail.com
Target Milestone: ----
Hi Team,
I have recently deployed our enterprise .war in tomcat8.0.32 version ,without
any changes made to DB pool configuration .
Question :
With Tomcat6 according to documentation when we have testOnBorrow=true
parameter without any ValidationQuery . testOnBorrow does not any effect as no
validation query.
Wereas in Tomcat8 ,if we donot have any ValidationQuery the documentation says
it checks for isValid() function.
But when i deployed the.war in tomcat8.0.32 with same DBpool config[without
ValidationQuery] , i could see intermediate connection errors with below
exception:
SQLException : Failed to validate newly established connection .
If i add the validationQuery to the configuration i doNot see any error.
DB used : db2
jar used : db2jcc4.jar
I want to understand why is the isValid() not working in mycase .
Is this any issue with tomcat8.0.32?????
