The oracle instant client 12_2 or 12_1 doesn't work on Linux for 12c DB server

[jaydeept]

Hello, I am using this package for my project which is based on .Net Core 2. I have downloaded the Oracle Client of version 12_2 and found that my test cases are passing on Windows OS. But on Linux with same client I got the error: Error while trying to retrieve text for error ORA-01804. Then I tried with client 11_2 and found that it's working fine on Linux. Does it have anything to do with the package you are providing?

Olá, boa noite jaydeept.

Os testes no qual realizei no Ubuntu 17.10, foi justamente com a versão do Client Oracle 12.2.0.1.0 http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

Instant Client Package - Basic: All files required to run OCI, OCCI, and JDBC-OCI applications Download instantclient-basic-linux.x64-12.2.0.1.0.zip (68,965,195 bytes) (cksum - 3923339140)

Em uma breve pesquisa sobre o erro, as causas mais comum para ocorrer esse problema são as váriveis de ambiente:

Common causes:

LD_LIBRARY_PATH is not correctly set. ORACLE_HOME is not correctly set. NLS_LANG is not correctly set.

Siga as instruções de instalações e valide se as variáveis estão corretamente de acordo com as instruções http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html#ic_x64_inst

Hello @ericmend ,

I did set below variables following your example:

export LD_LIBRARY_PATH=/instantclient_11_2:$LD_LIBRARY_PATH export OCI_HOME=/instantclient_11_2 export OCI_LIB_DIR=/instantclient_11_2 export PATH=/instantclient_11_2:$PATH export NLS_LANG=SLOVAK_SLOVAKIA.UTF8

These variables are for 11_2 but I did set for 12_2 and 12_1 as well.

Olá @jaydeept

Tente os passos: (Ubuntu) apt-get update && apt-get install -y libaio1 libaio-dev

Descompacte o pacote no diretório /opt/oracle/instantclient

ln -s /opt/oracle/instantclient/libclntsh.so.12.1 /opt/oracle/instantclient/libclntsh.so \
&& ln -s /opt/oracle/instantclient/libocci.so.12.1 /opt/oracle/instantclient/libocci.so

Adicione as variáveis de ambiente:

export LD_LIBRARY_PATH=/instantclient_11_2:$LD_LIBRARY_PATH
export OCI_HOME=/instantclient_11_2
export OCI_LIB_DIR=/instantclient_11_2
export PATH=/instantclient_11_2:$PATH
export NLS_LANG=SLOVAK_SLOVAKIA.UTF8

Valide se as váriveis foram adicionadas com sucesso:

echo $LD_LIBRARY_PATH
echo $OCI_HOME
echo $OCI_LIB_DIR
echo $PATH
echo $NLS_LANG

Se funcionar, vou atualizar o readme
