./setupCAUIMServer_linux.bin: line 3419: /tmp/install.dir.4014/Linux/resource/jre/bin/java: Permission denied
./setupCAUIMServer_linux.bin: line 3419: exec: /tmp/install.dir.4014/Linux/resource/jre/bin/java: cannot execute: Permission denied

Environment

UIM Server 8.51
OS:  Linux RH 7.5 64-bit

Cause

Potential causes of getting "permission denied" from the UIM installer on Linux/Unix systems:

1. The /tmp directory in mounted with the "noexec" option set
2. SELinux is enabled and preventing the execution of the java JRE
3. The root user's umask setting is something other than 0022

Resolution

Depending on the root cause of the "permission denied" error, engage the Linux/Unix administrator to:

1.  Remove the "noexec" option from the /tmp directory mount
2.  Disable SELinux
3.  Change the root user's umask setting to 0022 to assure that correct permissions are applied to files/directories created by the root user during the UIM Server installation.
