JDK 'java.security.Security' Package Causing Poor Performance on AIX
(Doc ID 297602.1)
Last updated on JUNE 02, 2023
Applies to:
Oracle Containers for J2EE - Version 9.0.3.0.0 to 10.1.2.0.0 [Release 9iAS to AS10gR2]z*OBSOLETE: IBM AIX 4.3 Based Systems (64-bit)
IBM AIX 4.3 Based Systems (64-bit)
AIX 4.3 Based Systems (64-bit)
Secure JSP applications
IBM’s AIX 5L Based Systems (64 bit)
Oracle Application Server 9.0.4.0.0
JDK 1.4.1
Symptoms
Every time Oracle’s HTTPClient opens an SSL socket, the java.security.Security.getAlgClassName()
is unzipping a JAR file. This is resulting in higher than expected CPU cycles and slower performance.
SUN’s JDK 1.4.1 src for java.security.Security class does not contain the getAlgClassName method.
Looking at the java.security configuration file on AIX, the file shows:
security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.net.ssl.internal.ssl.Provider
security.provider.3=com.ibm.jsse.IBMJSSEProvider
security.provider.4=com.ibm.crypto.provider.IBMJCE
security.provider.5=com.ibm.security.jgss.IBMJGSSProvider
security.provider.6=com.ibm.security.cert.IBMCertPath
The sun.security.provider.Sun is not included in the IBM runtime jar.
If the sun.security.provider.Sun entry is removed from the java.security,
CPU performance increases (45.44% CPU) when compared to the 62.42% CPU before the change.
