This note provides recommended c3p0.properties values for improving the performance and system stability of SAS Digital Marketing version 6.x.
The c3p0.properties are set for the SAS Digital Marketing Server, bess.war, and sdm.war servers. In release 6.3 and later, the properties for the SAS Digital Marketing Server are included in the c3p0.properties file in sdm.war.
For SAS® Digital Marketing 6.1_M1:
For SAS Digital Marketing Server, the default c3p0 settings are as follows:
c3p0.acquireRetryDelay=1000
c3p0.numHelperThreads=4
c3p0.maxPoolSize=25
c3p0.acquireRetryAttempts=5
c3p0.acquireIncrement=1
For sdm.war and bess.war, the default c3p0 settings are as follows:
c3p0.acquireRetryDelay=1000
c3p0.numHelperThreads=4
c3p0.maxPoolSize=10
c3p0.acquireRetryAttempts=5
c3p0.acquireIncrement=1
For SAS® Digital Marketing 6.3, 6.4 and 6.5

c3p0.maxPoolSize=25
c3p0.acquireRetryAttempts=5
c3p0.acquireIncrement=1
For bess.war, the default c3p0 settings are as follows:
c3p0.acquireRetryDelay=1000
c3p0.numHelperThreads=4

For more information about an issue with setting the c3p0.properties in SAS Digital Marketing Server 6.1_M1, see SAS Note 54654, "Default and updated c3p0 properties are not honored for the SAS® Digital Marketing Server."
If you experience performance issues, set the c3p0 logging to review use, as described in SAS Note 54664 "Setting up logging for monitoring c3p0 use in SAS® Digital Marketing."
To improve the performance and stability of SAS Digital Marketing, consider updating the c3p0.properties file in line with the following advice:
Set c3p0.maxPoolSize using the following formulas:
In these formulas:
Set c3p0.numHelperThreads to 8, if either or more cores are available when you increase c3p0.maxPoolSize.
Monitor and increase memory allocation for the servers, as needed.
