If you are going to install on a Linux system, the library libcrypt.so must be present to support the security infrastructure. If you do not see the libcrypt.so file in the /usr/lib64 directory for Linux x86_64, install the rpm package glibc-devel.

If you are going to install on a Linux x86_64 system, install the rpm package compat-libstdc++ from your operating system distribution using the vendor instructions.

If you are going to install on a SUSE Linux Enterprise Server 11 SP1 system, and you have configured the system to use the Blowfish algorithm to encrypt user passwords, download and install patch 18 Aug 2011 - glibc 4944 from Novell Support. This patch fixes an operating system bug relating to user authentication. For detailed information, see Novell’s SUSE Security Announcement: SUSE-SA:2011:035.

If you are going to install EntireX on a UNIX system, make sure you have set sufficient user limits for the shell you use to start the installation and the product daemons. If your system policy allows it, Software AG recommends setting the value for coredump, data, file, memory, and threads to unlimited, and the value of nofiles to 8192. For more information about setting and displaying the ulimits, read the man page or ask your system administrator.

If you are going to install EntireX on a UNIX NFS file system and want to do user authentication for EntireX Broker against the local operating system, you must mount the NFS file system with the suid option, which allows set-user-identifier or set-group-identifier bits to take effect.
