I see the error “HTTP-503 ORA-12154” in the file ORACLE_HOME/Apache/Apache/conf/error_log. What does this mean?
This error means that mod_plsql is unable to connect to the database. Ensure that: The database is up and running. The username and password information in the DAD is correct. The middle-tier is able to connect to the database using the PlsqlDatabaseConnectString parameter in the DAD. In most situations, the problem occurs because SQL*Net is not able to resolve the connect string parameter using the configuration information under ORACLE_HOME/network.101/admin. For entries configured with TNSFormat or NetServiceNameFormat, validate the connect string information by using tnsping dad_connect_string. For example: tnsping “cn=iasdb,cn=oraclecontext” or tnsping iasdb.us.oracle.com For entries configured with SIDFormat and ServiceNameFormat, ensure that the hostname, port, and SID/service_name information match for the database listener. After verifying this, confirm that SQL*Plus can connect to the database using the DAD username, password, and connect string. If this does not work, refer
