Common administration tasks are described in the following sections:
The following topics are described in this section:
To start SQL*Plus, enter the following:
When you are prompted for parameters, enter
This prevents SQL*Plus from prompting you for user name and password. Later you can explicitly connect to the database. For example:
SQL> CONNECT / AS SYSDBA
For more ways to start SQL*Plus, refer to "Running SQL*Plus" in Oracle Database User's Guide for Fujitsu BS2000/OSD.
Set Task Switch 1 to on (
/MODIFY-JOB-SWITCHES ON=1). This forces SQL*Plus to read in data from the procedure, rather than prompt you at the terminal.
Before starting SQL*Plus in the POSIX shell, you must set the environment variable
ORACLE_HOME and extend the POSIX variable PATH by the path to the Oracle
$ORACLE_HOME/bin. For example:
$ ORACLE_HOME=/u01/app/orac1120/product/dbhome_1 $ export ORACLE_HOME $ PATH=$ORACLE_HOME/bin:$PATH $ export PATH
Alternatively, you can process the profile
oracle_home_path/.profile.oracle, which is created during the installation of the Oracle software under POSIX. This profile sets and expands the most important variables like
PATH. Process the profile as follows:
$ . /u01/app/orac1120/product/dbhome_1/.profile.oracle
If you want to start SQL*Plus for a specific Oracle instance, then you must also set the variable
ORACLE_SID. For starting an Oracle server process, the BS2000 variable
BGJPAR is required. This variable is not set by running
If you want to start a background job with special job parameters, for example, a job should be assigned to a special
JOB-CLASS, then ensure that the variable
BGJPAR is set in your environment.
$ ORACLE_SID=orcl $ export ORACLE_SID $ BGJPAR='START=SOON,CPU-LIMIT=NO,J-C=JCBORA,LOGGING=*NO' $ export BGJPAR
You can start SQL*Plus in the same way as on other UNIX systems with the following command:
$ sqlplus /nolog $ SQL> connect / as sysdba
The SQL*Plus HOST command enables you to enter a BS2000 command, while you are logged on to SQL*Plus.
Keep the following points in mind when using the
If you enter the
HOST command without any BS2000 command, then it takes you to the command level. To return to SQL*Plus, you must use the
RESUME command in BS2000 or the
exit command in the POSIX subshell.
If you enter the
HOST command with a system command in the BS2000 environment, then you can only run BS2000 commands. In the POSIX shell, you can run shell commands and BS2000 commands by using the shell command
Start a text editor in SQL*Plus with the
EDIT command, if you want to edit an SQL statement.
If you run SQL*Plus in the native BS2000 environment, then the only editor supported is BS2000
If you run SQL*Plus in a POSIX shell, then the default editor depends on the terminal connected with your POSIX session. If the POSIX shell is started on a blockmode terminal, then the default editor in SQL*Plus is set to
edtu. If the POSIX shell is started by a remote X-client through
ssh using a xterm terminal, then the default editor in SQL*Plus is set to
SQL*Plus provides the opportunity to define a preferred text editor with the
DEFINE _EDITOR command. In the BS2000 environment, SQL*Plus accepts any editor you specify in the
DEFINE _EDITOR command, but the called editor is always the
EDT. In the POSIX environment you can define a preferred editor. For example, if you want to define the editor, used by the
EDIT command, to be the POSIX editor
edtu, then enter the following command in SQL*Plus:
DEFINE _EDITOR = edtu
The editor in the BS2000 environment is always the
vi does not work on blockmode terminals.
edtu does not work on xterm terminals.
The DBA can update the global SQL*Plus profile file,
$ORAC1120.SQLPLUS.ADMIN.GLOGIN.SQL, which is run when a user logs in to SQL*Plus. This file is run before the user's local
LOGIN.SQL and is provided to enable sites to set up several defaults useful to all users. You can place any SQL and SQL*Plus statement in
See Also:SQL*Plus User's Guide and Reference for more information about customizing SQL*PLUS profiles
Oracle uses two parameter files when starting the database:
ORAENV file, the environment definition file, which contains BS2000-specific information. In the
ORAENV file you identify the database to be started, or shut down. You can use this file to set configuration variables, which adapt the Oracle Database to the local operating system and application environment.
The initialization file
INIT.ORA or the server parameter file
SPFILE, which exists in all Oracle Database implementations and contains database-specific parameters.
This section describes the following:
ORAENV file is identified by
SID is the database identifier. The same
ORAENV file must be used by SQL*Plus in BS2000 and by all background jobs. This is ensured by the installation procedures, which create the basic
ORAENV file. Refer to Appendix B, "Oracle Environment Variables", for details of required and optional
If you use SQL*Plus in the POSIX shell, then the requested BS2000 parameters set in the
ORAENV file must be specified. You can set the variables in the POSIX environment or use the facility to access the BS2000
ORAENV file. When specifying the
SID in the POSIX
ORAENV filename, ensure that the
SID in the filename and the
SID variable use exactly the same case. For example, if you create a POSIX
ORAENV file with the
SID in the filename in uppercase, then you must set the
ORACLE_SID using exactly the same
$ echo '$ORADATA.ORCL.P.ORAENV' > $ORACLE_HOME/dbs/oraenvORCL $ ORACLE_SID=ORCL $ export ORACLE_SID $ sqlplus /nolog $ SQL> connect / as sysdba
Refer to "Starting Oracle Utilities in the POSIX environment" in Oracle Database User's Guide for Fujitsu BS2000/OSD, for more information about how to set POSIX environment variables.
Startup requires the
INIT.ORA parameter file, which contains a list of specifications for the Oracle database. These generic, that is, platform independent parameters, are used to setup the instance. Refer to Oracle Database Administrator's Guide and Oracle Database Reference for full descriptions of these parameters.
You can choose to maintain initialization parameters in a binary server parameter file. A server parameter file is initially built from a traditional text initialization parameter file using the
CREATE SPFILE command. If you enter the following command:
CREATE SPFILE FROM PFILE;
SPFILE name nor
PFILE name is specified, then Oracle looks for a text initialization file
.DBS.INIT.ORA and creates a server parameter file
A default initialization file, called
$ORAC1120.DEMO.DBS.INIT.ORA, is distributed with Oracle Database. During the database creation procedure, this file is copied to the
DBA User ID and renamed,
sid is the 1 to 4 character database ID you specified at the beginning of the database creation procedure.
Oracle determines the value of
SID by retrieving the
ORASID environment variable defined in the
ORAENV file for the database. When you issue the
STARTUP command with no
PFILE clause, Oracle locates the initialization parameter file by examining file names in the following order:
If you want to use some other initialization file, then use the argument
PFILE. For example, to bring up a previously created database using an initialization file called
TEST.INIT.ORA, enter the following:
/START-PROGRAM $ORAC1120.SQLPLUS * /NOLOG
At the SQL*Plus prompt, enter:
SQL> CONNECT / AS SYSDBA SQL> STARTUP PFILE=TEST.INIT.ORA
This section describes the preparations for a remote startup using SQL*Plus:
Usually, Oracle Database 11g Release 2 listener parameter file (
LISTENER.ORA) does not contain a static service registration section (
SID_LIST) for a database service. In case of a remote startup you must define this section for the desired database. For example:
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = ORCL)))
The listener must be running on the computer where the instance is to be started. The listener must statically register the instance. If the listener does not run under the same user ID as the instance you want to start, then you must define the admissions to start a job under the user ID of the instance in the listener's
ORAENV file or you must use SECOS, Fujitsu's Security Control System for BS2000/OSD. For more information refer to the Configuring the Network chapter in the Oracle Net Services section of this guide.
Create a password file with the Oracle utility
ORAPWD under the user ID of the instance you want to administrate. For more information of how to use
ORAPWD, refer to Oracle Database Administrator's Guide. To run the
ORAPWD utility on BS2000, use the following command:
/START-PROGRAM $ORAC1120.ORAPWD *file=password_file password=my_password entries=10
The name of the password file is taken from the parameter
SSSIDPWF. So you must add this parameter to the
ORAENV file of the instance you want to start:
SSSIDPWF = password_file
REMOTE_LOGIN_PASSWORDFILE must be set to
EXCLUSIVE in the initialization file of the instance.
REMOTE_LOGIN_PASSWORDFILE = EXCLUSIVE
Execute SQL*Plus on the remote computer and connect as user
sys to a server of the instance you want to startup. In the following example, which shows the commands for SQL*Plus on a UNIX client, we use the net service name orcl_on_bs2000 to address the remote instance on the BS2000 computer:
sqlplus /nolog SQL> connect sys@orcl_on_bs2000 as sysdba Enter password: password Connected SQL> startup ...
Automatic Diagnostic Repository (ADR) is a file-based hierarchical data store for depositing diagnostic information produced by diagnostic framework clients. The repository contains data describing incidents, traces, dumps, alert logs, health check records, SQL Trace information, and other information essential for problem diagnosis.
See Also:"Managing Diagnostic Data" in Oracle Database Administrators Guide for more information about Automatic Diagnostic Repository
This section describes the following:
Automatic Diagnostic Repository (ADR) is a directory structure that is stored outside of the database. It is therefore available for problem diagnosis when the database is down.
The directories and files of the Automatic Diagnostic Repository are stored in the POSIX file system.
See Also:Oracle Database Administrator's Guide for information about the directory structure
The ADR root directory is known as ADR base. Its location is set by the
DIAGNOSTIC_DEST initialization parameter. For example:
If this parameter is omitted or left null, then the database sets
DIAGNOSTIC_DEST upon startup as follows:
If environment variable
ORACLE_BASE is set, then
DIAGNOSTIC_DEST is set to the directory designated by
If environment variable
ORACLE_BASE is not set, then
DIAGNOSTIC_DEST is set to
Within ADR base, there can be multiple ADR homes, where each ADR home is the
root directory for all diagnostic data, such as traces, dumps, the alert log, and so on, for a particular instance of a particular Oracle product or component.
Oracle Net Services also store diagnostic data in the ADR. The location for diagnostic information for Oracle Net Services is set by the parameters
listener_name. These are set in the Oracle Net Services parameter files
See Also:"Troubleshooting Oracle Net Services" in Oracle Net Services Administrator's Guide for more information about diagnostic information for Oracle Net Services
You can read the text files of the Automatic Diagnostic Repository with text editors such as
edtu, or with POSIX shell commands such as
You can investigate the ADR with the utility ADRCI.
ADR Command Interpreter (ADRCI) is a utility that enables you to investigate problems, view health check reports, and package first-failure diagnostic data within a command-line environment. You can then upload the package to Oracle Support. ADRCI also enables you to view the names of the trace files in the ADR, and to view the alert log with XML tags stripped, with and without content filtering.
See Also:"ADRCI: ADR Command Interpreter" in Oracle Database Utilities for more information about ADRCI
Start the command-line utility ADRCI in the POSIX shell. Before starting ADRCI, set the environment variable
ORACLE_HOME and extend the environment variable
PATH by the path name of the Oracle directory
oracle_home_path/bin. Additional environment variables, such as
ORACLE_SID, are not required. Refer to "Starting Oracle Utilities in the POSIX environment" in Oracle Database User's Guide for Fujitsu BS2000/OSD for more information about Oracle Database utilities.
After setting these environment variables, start ADRCI in the POSIX shell by entering
adrci after the POSIX shell command prompt.
Note:ADRCI cannot be started in the normal BS2000 environment. ADRCI must be started in the POSIX shell.
Display the current ADR base with the ADRCI
show base command. The current ADR home can be displayed with the
show homes command.
Set ADR base with the
set base command. ADR home can be set with the
set home command.
show alert shows the contents of the alert log in a text editor.
If you use a blockmode terminal, then the default editor for ADRCI on Fujitsu BS2000/OSD is
edtu. If you use an xterm terminal after having logged in to POSIX through
ssh, then the default editor for ADRCI is
You can either select the preferred text editor by setting the environment variable
EDITOR before starting ADRCI or specify your preferred text editor within ADRCI with the ADRCI
set editor command.
Note:The editor vi does not work on blockmode terminals and the editor edtu does not work on xterm terminals.
With ADRCI you can invoke Incident Packaging Service (IPS) to create packages for incidents with the commands
ips create package and
ips generate package. The resulting zip file can be uploaded to Oracle Support.
To check the data-structure integrity of offline databases, use the
DBVERIFY command-line utility. To start
DBVERIFY enter the following command:
You can now enter the command, for example:
file=ora11.dbs.database1.dbf blocksize=4096 feedback=100
