0040 I. === STANDALONE INSTALLATION ===
0041
0042
0043 1. ORACLE_HOME
0044
0045 In order to compile, make sure your $ORACLE_HOME is set
0046 correctly.
0047
0048 On standard CERN systems (like lxplus) the normal $ORACLE_HOME does not
0049 have the neccessarry OCCI header files in its directory structure.
0050 You can use the following for your $ORACLE_HOME:
0051
0052 prompt> export ORACLE_HOME=/afs/cern.ch/cms/external/lcg/external/oracle/10.1.0.3-1/slc3_ia32_gcc323
0053
0054 NOTE: Be sure there is no trailing slash at the end of this directory
0055 name! If there is you may get a run-time error "ERROR: Connection
0056 Failed: ORA-32101: cannot create OCI Environment".
0057
0058 If the $ORACLE_HOME is not prepared on your machine you can download
0059 the ORACLE instant client from
0060
0061 http://oracle.com/technology/software/tech/oci/instantclient/index.html
0062
0063 You may have to register a free account on oracle.com.
0064
0065
0066 2. LD_LIBRARY_PATH
0067
0068 Next you should set your $LD_LIBRARY_PATH:
0069
0070 prompt> export LD_LIBRARY_PATH=$ORACLE_HOME/lib
0071
0072
0073 3. Connection Information
0074
0075 Edit the test/TestCondDB.cpp file to set the correct connection
0076 information for the database you plan to use.
0077
0078
0079 4. Compiling
0080
0081 Compile the program by running 'make -f makefile.standalone' in the src directory.
0082
0083
0084 5. Running
0085
0086 When the compiling is finished you can run the example programs
0087 from the test/ directory.
0088
0089 prompt> ./test/TestCondDB
0090
