On Solaris platform, Process:getProcess() Hawk method from tibhawkhma relies on ioctl() to retrieve process information from OS level, but this method is no longer available from Solaris 11.4 as mentioned in End of Features (EOF) for Oracle Solaris 11.4.

---------------------------------------------------------------
ioctl-based /proc Interface
Support for the old ioctl-based version of the /proc interface is no longer available. If your application code uses the old interface, update the code to use the structured /proc interface that was introduced in Oracle Solaris 2.6 (1997). For more information, see the proc(4) man page.
----------------------------------------------------------------

This will result in Process:getProcess() not returning any process information, and also will result in application status unknown from tibco administrator GUI for the machine running on Solaris 11.4 GA version(Oracle Solaris 11.4.0.0.1.15.0) without any SRU installed.

Following errors will occur in Hawk_Process.log if debug trace of tibhawkhma is enabled:
-----------------------------------------------------------------
DEBUG 05/29/2019 15:10:54 Function ioctl(PIOCSTATUS) failed for file /proc/0. OS error 25: Inappropriate ioctl for device.
DEBUG 05/29/2019 15:10:54 Function ioctl(PIOCSTATUS) failed for file /proc/5. OS error 25: Inappropriate ioctl for device.
DEBUG 05/29/2019 15:10:54 Function ioctl(PIOCSTATUS) failed for file /proc/6. OS error 25: Inappropriate ioctl for device.
-----------------------------------------------------------------

Oracle has a defect to reintroduce the ioctls(which was dropped in Solaris 11.4 GA version). Please refer to the defect below.
