If, after starting your application in z/OS, you see the **Not Marked Program Controlled** messages or errors with the return code 139:

```java
BPXP015I HFS PROGRAM /tmp/libdynatrace-oneagent-odin-java5848811742465559217.so
IS NOT MARKED PROGRAM CONTROLLED.

```

You need to enable program control for the z/OS Java module. To do so

1. Expand `dynatrace-oneagent-zos-java.jar`that you downloaded into a program controlled folder.

2. Mark the appropriate `.so` file (31 or 64-bit) in the `lib/zos-s390/` directory as program-controlled

3. Add `zos-native-library-override` to your JVM argument.

4. Restart your application server.
