We are currently running 7.2.1 on Tomcat7 and Java8. When our oracle RAC environment has maintenance we are seeing issues/errors in our logs (see below). A suggestion has been made that the Tomcat configuration "testOnBorrow" would help in this situation. I do not see any reference to this in the 7.2.1 Tomcat/Oracle installation guide. However, it is mentioned in the 7.4 installation guide as something that needs to be in place when using Tomcat7.
Is it Pega's recommendation to use this setting in all versions of Pega on Tomcat7?
Thanks for the information. We are using: Database version: Oracle Database 12c Enterprise Edition Release 220.127.116.11.0 - 64bit Production
As an fyi, the issue only occurs when there is some type of patching on the Oracle farm; during those patching efforts one server in the RAC will go offline and the others continue to handle traffic. It appears that prpc is maintaining connections to the server that goes offline.
