Oracle10g前，Oracle并不提供UNIX/Linux下的ODBC驱动，用的最为广泛的是UnixOdbc，UnixOdbc的配置不算复杂，但是如果不顺利的话也会遇到一些问题。
今天成功安装配置了UnixOdbc把步骤总结一下供参考。 UnixOdbc可以在官方站点上下载。
以下是测试及配置步骤:
首先你需要安装Oracle客户端，并且确认网络可达。
1.使用isql进行测试
[root@magic root]# isql ********************************************** * unixODBC - isql * ********************************************** * Syntax * * * * isql DSN [UID [PWD]] [options] * * * * Options * * * * -b batch.(no prompting etc) * * -dx delimit columns with x * * -x0xXX delimit columns with XX, where * * x is in hex, ie 0x09 is tab * * -w wrap results in an HTML table * * -c column names on first row. * * (only used when -d) * * -mn limit column display width to n * * -v verbose. * * -lx set locale to x * * --version version * * * * Notes * * * * isql supports redirection and piping * * for batch processing. * * * * Examples * * * * cat My.sql | isql WebDB MyID MyPWD -w * * * * Each line in My.sql must contain * * exactly 1 SQL command except for the * * last line which must be blank. * * * * Please visit; * * * * http://www.unixodbc.org * * pharvey@codebydesign.com * * nick@easysoft.com * **********************************************
[root@magic root]# isql --versio unixODBC 2.2.10 [root@magic root]# which isql /usr/bin/isql
2./etc/odbc.ini文件配置
[ODBC Data Sources] test = Oracle ODBC Driver DSN
[default] Driver = /usr/local/easysoft/oracle/libesoracle.so
[test] Driver = /usr/local/easysoft/oracle/libesoracle.so
Description = Oracle server = 172.16.1.21 ServerType = Oracle Port = 1521 User = username Password = password Database = ava SID = ava METADATA_ID = 0 ENABLE_USER_CATALOG = 1 ENABLE_SYNONYMS = 1
[default] Driver = /usr/local/easysoft/oracle/libesoracle.so
3. /etc/odbcinst.ini 文件配置
; ; odbcinst.ini ;
[test] Description=ODBC for ORACLE Driver = /usr/local/easysoft/oracle/libesoracle.so
[ODBC] Trace=1 Debug=1 Pooling=No
4.sqlnet.ora文件配置
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
5.tnsnames.ora文件配置
ava = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.18.21)(PORT = 1521)) ) (CONNECT_DATA = (SID = ava) ) ) |
|---|
6.测试
[root@magic admin]# isql test -v +---------------------------------------+ | Connected! | | | | sql-statement | | help [tablename] | | quit | | | +---------------------------------------+ SQL> |
|---|
7.启动LDAP
[root@magic admin]# /usr/local/libexec/slapd -d 5 -f /home/eygle/openldap/slapd.conf @(#) $OpenLDAP: slapd 2.2.17 (Dec 29 2004 20:45:12) $ root@magic.hawa.cn:/home/eygle/openldap/openldap-2.2.17/servers/slapd daemon_init: daemon_init: listen on ldap:/// daemon_init: 1 listeners to open... ldap_url_parse_ext(ldap:///) daemon: IPv6 socket() failed errno=97 (Address family not supported by protocol) daemon: initialized ldap:/// daemon_init: 2 listeners opened slapd init: initiated server. ==>backsql_initialize() <==backsql_initialize() >>> dnNormalize: => ldap_bv2dn(cn=Subschema,0) ldap_err2string <= ldap_bv2dn(cn=Subschema)=0 Success => ldap_dn2bv(272) ldap_err2string .... ==>backsql_open_db_conn() backsql_open_db_conn(): connected, adding to tree <==backsql_open_db_conn() backsql_get_db_conn(): first call -- reading schema map ==>backsql_load_schema_map() ldapinfo.dn_ru field exists in the schema backsql_load_schema_map(): at_query "SELECT name,sel_expr,from_tbls,join_where,add_proc,delete_proc,param_order, expect_return,sel_expr_u FROM ldap_attr_mappings WHERE oc_map_id=?" <==backsql_load_schema_map() <==backsql_get_db_conn() ==>backsql_free_db_conn() backsql_free_db_conn(): closing db connection ==>backsql_close_db_conn() <==backsql_close_db_conn() <==backsql_free_db_conn() <==backsql_db_open(): test succeeded, schema map loaded slapd starting |

启动成功.
