In some cases it is necessary to replace the JCo of ECTR with a current version. This replacement can be done either by installing a current version of ECTR or by manually replacing the JCO libraries. Since JCo is usually downward compatible, an exchange with a higher version is possible without problems.
This explains the manual exchange of the JCo libraries.
Check the currently used version
Open the console logfile from logfile directory. Search for this line:
Download the current available version
You can find the latest version here. Download the latest "Microsoft Windows and Windows Server" - "64-bit x86*" file for the appropriate revision level.
For ECTR older then 5.1.16 / 188.8.131.52 use JCO 3.0.x. JCo 3.1 is not compatible with 184.108.40.206 and older.
- Replace sapjco3.dll + sapjco3.pdb in directory <ECTR>\basis\sys\win\lib64.
If you're running the 5.1 installation on a 32 bit platform (quite unlikely), you need also to replace the lib32 dll and pdb.
- Replace sapjco3.jar in directory <ECTR>\basis\libraries.
