After that I could run SQLPlus and access the remote database sucessfuly, BUT when I run an application that uses Oracle instant client driver I got this error :
[FireDAC][Phys][Ora]-314. Cannot load vendor library [libclntsh.so]. Hint: check it is in the PATH or application EXE directories, and has x64 bitness.
The application is a Delphi RAD Server (EMS) 10.3.1 module (.so) that runs under Apache 2.4, compiled for Linux 64. This program access a database table by using Delphi components TFDPhysOracleDriverLink, TFDManager and TFDConnection.
In TFDConnection component I configure the database access information : driver, driver file location (libclntsh.so), hostname and instance name.
This same program when deployed to Windows works fine, but when deployed to Linux generates the above error.
1) Is there any additional step to configure instant client to Linux ?
2) Is there any compatibility issue of Delphi 10.3.1 in Linux with oracle Instant Client ?
