Resolution:
Following is what TRA 5.4.x supports on Linux , there are two Linux installation files, please make sure you've installed the correct one.

TRA 5.4.0
        
Linux 2.4 kernel: 2.4.6 and up, glibc2.2.4 and up (x86)                                        
TIB_tra-suite_5.4.0_linux24gl22_x86.tar

Linux kernel version at least 2.4.2, gcc at least 2.96, and glibc at least 2.2.2      
TIB_tra-suite_5.4.0_linux24gl23_x86.tar  

TRA 5.4.1

Linux 2.4 (x86):kernel: 2.4.x, glibc2.2.x                                                                
TIB_tra-suite_5.4.1_linux24gl22_x86.tar

Linux 2.4,2.6 (x86):kernel: 2.4.x or 2.6.x, glibc2.3.x                                              
TIB_tra-suite_5.4.1_linux24gl23_x86.tar  

TRA 5.4.2

Linux 2.4 (x86): kernel:2.4.x, glibc2.2.x                                                                
TIB_tra-suite_5.4.2_linux24gl22_x86.tar

Linux 2.4, 2.6 (x86): kernel:2.4.x or 2.6.x, glibc2.3.x                                            
TIB_tra-suite_5.4.2_linux24gl23_x86.tar

As there are two Linux installation files, if you have glibc 2.3.x you should use the TIB_tra-suite_5.4.x_linux24gl23_x86.tar installer file not TIB_tra-suite_5.4.x_linux24gl22_x86.tar.

    So you need to uninstall all the dependent products ( BW /ADMIN/Adapters) first and then uninstall TIB_tra-suite_5.4.x_linux24gl22_x86.tar and then install again TIB_tra-suite_5.4.0_linux24gl23_x86.tar and dependent products.

Why do I sometimes get the exception "undefined symbol: _ZTI5MHash" on Linux platform?
