What are the possibilities to use a Raspberry Pi computer as an Oracle client?<\/p>\n

\"IMG_1653\"<\/a><\/p>\n

Besides other things I’ll show a possibility in this Blog to run the fat\/thick Oracle Client on a Raspberry Pi!<\/p>\n

REMARK: All examples below were made with an Rasperry Pi 3 and the OS Raspbian, which can be downloaded from
\nhttps:\/\/www.raspberrypi.org\/downloads<\/p>\n

First of all what’s possible with Java and Thin Clients?
\nRunning the Java-Programs sqldeveloper or its counterpart in command line mode sqlcl is of course possible on a Raspberry Pi:<\/p>\n

1.) sqldeveloper<\/p>\n

The prerequisite for running sqldveloper 17.4. (current version as of writing this Blog) is an installed JDK 1.8. As I had that installed by default, I could run sqldeveloper as documented. I.e.<\/p>\n


\npi@raspberrypi:~ $ sudo apt list --installed | grep jdk
\noracle-java8-jdk\/stable,now 8u65 armhf [installed]
\npi@raspberrypi:~ $ cd Oracle
\npi@raspberrypi:~\/Oracle $ unzip sqldeveloper-17.4.0.355.2349-no-jre.zip
\n...
\npi@raspberrypi:~\/Oracle $ cd sqldeveloper\/
\npi@raspberrypi:~\/Oracle\/sqldeveloper $ .\/sqldeveloper.sh
\n 
\nOracle SQL Developer
\nCopyright (c) 1997, 2017, Oracle and\/or its affiliates. All rights reserved.
\n<\/code><\/p>\n

\"sqldeveloper\"<\/a><\/p>\n

2.) sqlcl<\/p>\n

Installing sqlcl is as easy as installing sqldeveloper:<\/p>\n


\npi@raspberrypi:~\/Oracle $ unzip sqlcl-17.4.0.354.2224-no-jre.zip
\n...
\npi@raspberrypi:~\/Oracle $ alias sqlcl='\/home\/pi\/Oracle\/sqlcl\/bin\/sql'
\npi@raspberrypi:~\/Oracle $ sqlcl cbleile\/cbleile@192.168.178.65:1521\/prem122.localdomain
\n 
\nSQLcl: Release 17.4.0 Production on Tue Jan 09 14:28:56 2018

\nSQL> select table_name, tablespace_name from tabs;
\nTABLE_NAME TABLESPACE_NAME
\nT1 USERS
\n 
\nSQL>
\n<\/code><\/p>\n

3.) Running Java-Code using the JDBC Thin driver<\/p>\n

Running Java-Code with access to Oracle is easy as well. Just download the JDBC Thin Driver ojdbc8.jar and put it somewhere on the Pi. In the example below I actually do use the ojdbc8.jar from sqlcl:<\/p>\n


\npi@raspberrypi:~\/Oracle\/Java $ more Conn.java
\nimport java.sql.*;
\nclass Conn {
\npublic static void main (String[] args) throws Exception
\n{
\nClass.forName (\"oracle.jdbc.OracleDriver\");
\n 
\nConnection conn = DriverManager.getConnection (\"jdbc:oracle:thin:@\/\/192.168.178.65:1521\/prem122.localdomain\", \"cbleile\", \"cbleile\");
\n\/\/ @\/\/machineName:port\/SID, userid, password
\ntry {
\nStatement stmt = conn.createStatement();
\ntry {
\nResultSet rset = stmt.executeQuery(\"select BANNER from SYS.V_$VERSION where BANNER like '%Enterprise Edition%'\");
\ntry {
\nwhile (rset.next())
\nSystem.out.println (\"Connected to \"+rset.getString(1));
\n}
\nfinally {
\ntry { rset.close(); } catch (Exception ignore) {}
\n}
\n}
\nfinally {
\ntry { stmt.close(); } catch (Exception ignore) {}
\n}
\n}
\nfinally {
\ntry { conn.close(); } catch (Exception ignore) {}
\n}
\n}
\n}
\npi@raspberrypi:~\/Oracle\/Java $ javac Conn.java
\npi@raspberrypi:~\/Oracle\/Java $ java -cp ..\/sqlcl\/lib\/ojdbc8.jar:. Conn
\nConnected to Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production
\n<\/code><\/p>\n

4.) Running a fat Client on the Raspberry Pi<\/p>\n

Is it actually possible to run the normal Oracle thick\/fat Client on the Pi? As the Oracle Client Binaries are not available for the ARM processor it seems not possible, but emulating the x86-platform you actually can do it.<\/p>\n

The easiest way to run x86-Code on a Raspberry Pi is to actually buy the product ExaGear Desktop from Eltechs ( https:\/\/eltechs.com ) for aound 20 Euros (they usually sell it for 16 Euros).
\nREMARK: You can actually also install the QEMU image from https:\/\/github.com\/AlbrechtL\/RPi-QEMU-x86-wine , but that’s far more effortful.<\/p>\n

What is ExaGear? ExaGear is an emulator (i.e. a virtual machine) which emulates a x86 Debian Linux on your Raspberry Pi. After downloading ExaGear and unzipping it it’s installed easily on the Pi with just<\/p>\n


\n$ sudo .\/install-exagear.sh
\n<\/code><\/p>\n

Afterwards you can start it with the command exagear:<\/p>\n


\npi@raspberrypi:~ $ uname -a
\nLinux raspberrypi 4.9.59-v7+ #1047 SMP Sun Oct 29 12:19:23 GMT 2017 armv7l GNU\/Linux
\npi@raspberrypi:~ $ exagear
\nStarting \/bin\/bash in the guest image \/opt\/exagear\/images\/debian-8
\npi@raspberrypi:~ $ uname -a
\nLinux raspberrypi 4.9.59-v7+ #1047 SMP Sun Oct 29 12:19:23 GMT 2017 i686 GNU\/Linux
\npi@raspberrypi:~ $ arch
\ni686
\n<\/code><\/p>\n

I am now inside the x86 world. I.e. I can use this guest shell as if it were running on an x86 machine.
\nFirst I do update the repositories:<\/p>\n


\npi@raspberrypi:~ $ sudo apt-get update
\n...
\n<\/code><\/p>\n

The next step is to download the Oracle 32-Bit 12.2.-Client-Software to the raspberry pi. To be able to install the Oracle software a couple of libraries and programs need to be installed. I.e. inside exagear:<\/p>\n


\npi@raspberrypi:~\/Oracle\/Downloads\/client32 $ sudo apt-get install libxrender1 libxtst6 libxi6 libaio1 make gcc gawk
\n<\/code><\/p>\n

To avoid some errors I also had to create 3 symbolic links:<\/p>\n


\npi@raspberrypi:~\/Oracle\/Downloads\/client32 $ sudo ln -s \/usr\/lib\/i386-linux-gnu\/libpthread_nonshared.a \/usr\/lib\/libpthread_nonshared.a
\npi@raspberrypi:~\/Oracle\/Downloads\/client32 $ sudo ln -s \/usr\/lib\/i386-linux-gnu\/libc_nonshared.a \/usr\/lib\/libc_nonshared.a
\npi@raspberrypi:~\/Oracle\/Downloads\/client32 $ sudo ln -s \/usr\/bin\/awk \/bin\/awk
\n<\/code><\/p>\n

At that point I could install the Oracle Client software as usual:<\/p>\n


\npi@raspberrypi:~\/Oracle\/Downloads\/client32 $ .\/runInstaller
\nStarting Oracle Universal Installer...
\n 
\nChecking Temp space: must be greater than 415 MB. Actual 1522 MB Passed
\nChecking swap space: must be greater than 150 MB. Actual 828 MB Passed
\nChecking monitor: must be configured to display at least 256 colors
\n>>> Could not execute \/usr\/bin\/xdpyinfo Failed <<<<
\n 
\nSome requirement checks failed. You must fulfill these requirements before
\n 
\ncontinuing with the installation,
\n 
\nContinue? (y\/n) [n] y
\n<\/code><\/p>\n

xdpyinfo can be installed by installing the x11-utils on Debian, but it’s actually not necessary, so just continue by answering “y” at the prompt.<\/p>\n

The rest is a normal Oracle-Client installation. Here some screen shots:<\/p>\n

\"runInstaller1_1\"<\/a><\/p>\n

\"runInstaller2\"<\/a><\/p>\n

\"runInstaller6\"<\/a><\/p>\n

\"runInstaller8\"<\/a><\/p>\n

\"runInstaller10\"<\/a><\/p>\n

\"runInstaller12\"<\/a><\/p>\n

I created my small script to set the environment and was then able to run the client-software:<\/p>\n


\npi@raspberrypi:~ $ more oraclient.sh
\n#!\/bin\/bash
\n 
\nexport ORACLE_HOME=\/home\/pi\/Oracle\/app\/pi\/product\/12.2.0\/client_1

Summary: Is it possible to run an Oracle client on the Rasberry Pi? Yes, it is! Running native Java-applications using JDBC Thin Connections is not a problem at all. Running a fat Oracle Client is possible as well using x86 emulation software. Is this supported by Oracle? I do assume that like with any other non-Oracle-VM-solution you would have to prove possible issues by reproducing the problem on a bare metal x86 platform to be able to open a Service Request.<\/p>\n

Anyway, if you plan to run an Oracle 18c XE DB at home (see e.g. here
\nhttps:\/\/ora-00001.blogspot.de\/2017\/10\/oracle-xe-12c-becomes-oracle-xe-18c.html )
