To modify the oam-config.xml file, export the file from the database, update it, and then import it back to the database.

1. Set the following environment variables for Oracle Access Manager:
   • ORACLE_HOME
   • DOMAIN_HOME
   • JAVA_HOME
   • DB_ORACLE_HOME
2. Create the prop.properties file.
   The following shows an example of the prop.properties file.

   oam.entityStore.ConnectString=jdbc:oracle:thin:@dbhost.example.com:1521/servicename.example.com
   oam.entityStore.schemaUser=MYPREFIX_OAM
   oam.entityStore.schemaPassword=xxxxx
   oam.importExportDirPath=/tmp
   oam.frontending=params=oamhost.example.com;14100;http

3. Export oam-config.xml located in the DOMAIN_HOME/config/fmwconfig/ directory into temporary location (tmp) by running the following command:

   java -cp config-utility.jar:ojdbc11.jar oracle.security.am.migrate.main.ConfigCommand <Domain home> export <prop.properties>

   For example:

   $JAVA_HOME/bin/java -cp $ORACLE_HOME/idm/oam/server/tools/config-utility/config-utility.jar:$ORACLE_HOME/oracle_common/modules/oracle.jdbc/ojdbc11.jar oracle.security.am.migrate.main.ConfigCommand $DOMAIN_HOME export /tmp/prop.properties

4. Open the oam-config.xml file under /tmp folder in a text editor and update the required attribute.
5. Import oam-config.xml into the database by running the following command:

   java -cp config-utility.jar:ojdbc11.jar oracle.security.am.migrate.main.ConfigCommand <Domain Home> import <prop.properties>

   For example:

   $JAVA_HOME/bin/java -cp $ORACLE_HOME/idm/oam/server/tools/config-utility/config-utility.jar:$ORACLE_HOME/oracle_common/modules/oracle.jdbc/ojdbc11.jar oracle.security.am.migrate.main.ConfigCommand $DOMAIN_HOME import /tmp/prop.properties

   To update the oam-config.xml file in Windows environment:

   1. Navigate to <OS_DRIVE>\Users\<USERNAME>\<Documents>

      Here, <USERNAME> is the username of the logged-in user.

   2. Create the prop.properties file with the following entries:

      oam.entityStore.ConnectString=jdbc:oracle:thin:@<DB_HOSTNAME>:<DB_PORT></SERVICE_NAME>
      oam.entityStore.schemaUser=<OAM_SCHEMA_NAME>
      oam.entityStore.schemaPassword=<OAM_SCHEMA_PASSWORD>
      oam.importExportDirPath=<DIRECTORY_PATH>
      oam.frontending=params=WebLogicHost:OAMManagedServerPort:http(s)

   3. Copy config-utility.jar and ojdbc11.jar to <OS_DRIVE>\Users\<USERNAME>\Documents>.
   4. Set JAVA_HOME=<17.0.12.8_OR_HIGHER>
   5. Open the command prompt and navigate as shown:

      cd <OS_DRIVE>\Users\<USERNAME>\Documents>

   6. Run the following commands for export and import:

      For export:

      java -cp ".;config-utility.jar;ojdbc8.jar" oracle.security.am.migrate.main.ConfigCommand\<MIDDLEWARE_HOME>\user_projects\domains\<OAM_DOMAIN> export prop.properties

      For import:

      java -cp ".;config-utility.jar;ojdbc8.jar" oracle.security.am.migrate.main.ConfigCommand <Domain Home> import prop.properties

To modify OAM configuration parameters by using OAM REST API:

1. Edit the oamconfig_modify.xml file, change the OAM parameters. The following is a sample:

   <Configuration>
   <Setting Name="host" Type="xsd:string" Path="/DeployedComponent/Server/NGAMServer/Instance/oam_server1/host">@OAM_SERVER@1</Setting>
