![]() qibm/userdata/websphere/appserver///profiles/default/properties/* ![]() qibm/userdata/websphere/appserver///profiles/default/etc/* See the following directories in WAS V6.1 and later for the "default" profile/server: You would use these files to make your customizations. These files are already copied into your application server's profile root. The SystemDefault.properties file must have a CCSID of 819 or 1252 in order for it to be read correctly.įor a WebSphere Application Server Profile, the normal security configuration files cannot be overridden using the above Java properties. NOTE: The SystemDefault.properties file can be set globally for all JVMs (/QIBM/UserData/Java400/SystemDefault.properties) or for a specific JVM job user in the user's home directory specified on the user profile object (/home/jvmuser/SystemDefault.properties). Java = ProgramNameĪdd the properties to the SystemDefault.properties file: There are a variety of ways to specify these properties when the JVM is started. Refer to the IBM SDK Policy Files link for more information.Ĭom.=/policyfiles/unrestricted NOTE: This property is used to implement the JCE Unlimited Strength Policy Files for use with AES_256 cipher suites. # Determines whether this properties file can be appended to # whether or not we allow an extra policy to be passed on the command line QOpenSys/QIBM/ProdData/JavaVM/jdkxx/xxbit/jre/lib/security/Įnsure the master curity file contains the following: NOTE: These are the default values in the master curity file. QIBM/ProdData/Java400/jdkxx/lib/security/ ![]() You will want to check this file first to ensure the properties "policy.allowSystemProperty=true" and "security.overridePropertiesFile=true" are both set to true if you want to customize the locations of the java.policy and curity files. The master curity file is located in the following directories. Using these custom properties will insulate your Java applications from changes made to the global Java system LPP security configuration files when applying PTFs. The following properties may be used so the JVM can find and use these customized configuration files. It is recommended that you copy these files to another directory outside of the LPP system directories when making customizations. The default security configuration files include the curity, java.policy and cacerts files which are located in the /QIBM/ProdData/Java400/jdkxx/lib/security/ and /QOpenSys/QIBM/ProdData/JavaVM/jdkxx/xxbit/jre/lib/security/ directories. The Java LPP on the IBM i provides default files for the security configuration. ![]() This means it is very risky for clients/third parties to rely on changes/customizations made to any files in the /QIBM/ProdData/* or /QOpenSys/QIBM/ProdData/* directories because a PTF may overlay any changes/customizations. As a result, they will be updated/overlaid when Java PTFs are applied. These system directories are used for Licensed Program Product (LPP) data. Please refer to the appropriate section based on your JVM type.įiles that reside in the /QIBM/ProdData/* and /QOpenSys/QIBM/ProdData/* directory structures are "owned" by IBM. Java Virtual Machine is IBM Technology for Java. Choose option 1 to select the active job.ģ. Issue the WRKJOB JVMAPP1 command and press Enter.Ģ. The easiest way to find this is by displaying the job log for the JVM job you want to customize.įor example, if the job is called JVMAPP1, you would do the following from the command line:ġ. The directories containing the Java security configuration files are different between the two different JVM types, so you will need to figure out which JVM is in use with your job before you proceed. At IBM i 5.4 and 6.1, you have a couple of different JVM options (the "Classic JVM" and the "IBM Technology for Java VM (IT4J)").
