The current version of Oracle Secure Global Desktop 5.50.093 requires Oracle Linux 7.6+ as the only supported installation platform. Previous versions of Oracle Secure Global Desktop provided binaries to also install on Solaris x86 and SPARC.
The last version of Oracle Secure Global Desktop to support Solaris x86 and SPARC as installation platform is 5.40.935 which is out of premier support by the end of April 2020.
It is important to note that Oracle Secure Global Desktop 5.x will continue to support Solaris x86 and SPARC as application servers and continues to provide the enhancement modules for these operating systems and architectures.
