This appendix describes the Enterprise Manager Prerequisite Kit utility (EM Prerequisite Kit) that the installation wizard runs every time it installs or upgrades your Enterprise Manager. In particular, this appendix covers the following:
The EM Prerequisite Kit is a command line utility that runs repository-related prerequisite checks in your environment to ensure that you meet all the repository requirements for installing or upgrading an Enterprise Manager system.
The kit not only runs the prerequisite checks but also takes corrective action automatically, to the extent possible, when a prerequisite check fails. The kit also takes postrequisite steps to revert the corrective actions taken and ensure that the system is back to how it was before installing or upgrading the Enterprise Manager system.
The EM Prerequisite Kit is run internally by the Enterprise Manager Installation Wizard while installing or upgrading an Enterprise Manager system.
Note:
You can download the latest version of EM Prerequisite Kit from the Self Update framework as follows:In Cloud Control, from the Setup menu, select Extensibility and then click Self Update.
On the Self Update page, download the new version of XMLs under the entity EM Deployment Prerequisite Resources Updates, if there are any available.
Once you download and apply these updates, you cannot rollback to the previous version of XMLs.
The EM Prerequisite Kit is run internally by the Enterprise Manager Installation Wizard while installing or upgrading an Enterprise Manager system. However, if any of the repository prerequisite checks fail for some reason, you can manually run them by invoking this kit.
The EM Prerequisite Kit is available in the following location of the software kit (DVD, downloaded software):
install/requisites/bin/emprereqkit
To run the EM Prerequisite Kit, do one of the following:
To view a list of repository requirements to be met without taking any corrective actions, run the EM Prerequisite Kit from the software kit (DVD, downloaded software) as SYS user with the following arguments:
install/requisites/bin/emprereqkit -executionType install -prerequisiteXMLLoc <prereq_xml_location> -connectString <connect_string> -dbUser SYS -dbPassword <db_password> -dbRole sysdba -showPrereqs
To run the prerequisite utility and also take corrective actions to meet the repository requirements, run the EM Prerequisite Kit from the software kit (DVD, downloaded software) as SYS user with the following additional arguments:
install/requisites/bin/emprereqkit -executionType install -prerequisiteXMLLoc <prereq_xml_location> -connectString <connect_string> -dbUser SYS -dbPassword <db_password> -dbRole sysdba -runPrerequisites -runCorrectiveActions
Note:
To learn about the other arguments that can be passed with the kit, see Running the EM Prerequisite Kit with Additional Arguments.Once the Enterprise Manager system is installed or upgraded, the EM Prerequisite Kit and all the other files and directories present in the install/requisites/ directory of the software kit (DVD, downloaded software) are copied to the following location in the OMS home. So, in future, if you decide to install any plug-ins, then before installing them, ensure that you invoke the EM Prerequisite Kit from this location.
$<OMS_HOME>/install/requisites/bin/emprereqkit
Note:
The default XML files related to the prerequisite checks, which are stored in the
install/requisites/list directory on the software kit (DVD, downloaded software), are current at the time of the release of the product. However, after the release of the product, if a new prerequisite check is introduced or if an existing prerequisite check is updated, then you must do one of the following:
Enable the Self Update functionality within Enterprise Manager Cloud Control so that the new or updated prerequisite XML files are automatically downloaded to the $<OMS_HOME>/install/requisites/list directory.
Manually download the new or updated prerequisite XML files from Oracle store to the $<OMS_HOME>/install/requisites/list directory.
Table A-1 describes the additional arguments you can pass while invoking the EM Prerequisite Kit:

|
Existing Database Not to Have Database Control (only for fresh install) |
Fresh Install |
No |
(If you are upgrading from Enterprise Manager 10g Grid Control Release 5 (10.2.0.5) or higher, which uses an Oracle Database where the Management Repository is already created, that is, where the Grid Control SYSMAN schema is already created, then ignore this prerequisite. This prerequisite applies only when you install Enterprise Manager 12c Cloud Control Release 1 (12.1.0.1.0) using an existing, certified Oracle Database that has Database Control SYSMAN schema created, which you want to replace now with Grid Control SYSMAN schema.) Ensure that your existing, certified Oracle Database does NOT have Database Control SYSMAN schema. If it has, that is, if your existing database is configured with Database Control, then deconfigure it.
Note: If the deconfigure operation hangs, then refer to My Oracle Support note 375946.1 |
|
Existing Database Not to Have SYSMAN and SYSMAN_MDS Schema |
Fresh Install |
No |
(If you are upgrading from Enterprise Manager 10g Grid Control Release 5 (10.2.0.5) or higher, which uses an Oracle Database where the Management Repository is already created, that is, where the Grid Control SYSMAN schema is already created, then ignore this prerequisite. This prerequisite applies only when you install Enterprise Manager 12c Cloud Control Release 1 (12.1.0.1.0) using an existing, certified Oracle Database that has Database Control SYSMAN schema created, which you want to replace now with Grid Control SYSMAN schema.) Ensure that your existing, certified Oracle Database does NOT have Enterprise Manager Grid Control SYSMAN schema and Metadata (MDS) schema.
|
|
Database Initialization Parameters Requirements |
Install and Upgrade except db_block_size which applies only to install. |
No |
Ensure that you have correctly set the database initialization parameters for the existing, certified Oracle Database so that the Management Repository can be created. For information about setting the parameters, see Setting Database Initialization Parameters. |
|
Fine-Grained Access Control Requirements |
Upgrade |
No |
Ensure that the fine-grained access control option is set to TRUE in the existing, certified Oracle Database so that the Management Repository can be created. To verify this, run the following command: select value from v$option where parameter = 'Fine-grained access control'; |
|
UNDO Tablespace Size Requirements |
Install and Upgrade |
No |
Ensure that the UNDO tablespace has a minimum space of 200 MB. To verify this, run the following query: SELECT SUM(DECODE(autoextensible,'YES',200*1024*1024+1,bytes)) total FROM dba_data_files f, dba_tablespaces s WHERE s.contents = 'UNDO' AND s.tablespace_name = f.tablespace_name; Note: The result of this query is in bytes. If the minimum space is less than 200 MB, then set it to 200 MB by running the following command: alter database datafile <location datafile> resize 200M; |
|
UNDO Tablespace and Temporary Tablespace Settings Requirements |
Install and Upgrade |
No |
Ensure that the UNDO tablespace and the TEMP tablespace are autoextensible in the existing, certified Oracle Database. To verify this, run the following command: select count(*) from dba_temp_files where tablespace_name='TEMP' and AUTOEXTENSIBLE <> 'YES'; select count(*) from dba_data_files where tablespace_name='UNDOTBS' and AUTOEXTENSIBLE <> 'YES'; If the result of the query is 0, then the tablespace is autoextensible. If the result it not 0, then refer to Oracle Database Administrator's Guide available at the following location to make the tablespace autoextensible. http://www.oracle.com/technology/documentation/database.html |
|
Archive Logging Settings Requirements |
Install and Upgrade |
No |
(Recommended) Ensure that you turn on archive logging in the existing, certified Oracle Database for any environment where continuity of data is important. To verify this, run the following command in the SYS role: select log_mode from v$database; The result returned must be |
|
Tablespace-Related Hard Disk Space Requirements |
Install |
No |
Ensure that you allocate a minimum of 200 GB hard disk space for the following tablespaces: - Management Tablespace (mgmt.dbf) - Configuration Data Tablespace (mgmt_ecm_depot1.dbf) - JVM Diagnostics Data Tablespace (mgmt_ad4j.dbf) Oracle also recommends that you keep the auto-extend feature enabled for the tablespace data files. Note that the space requirement increases as the number of monitored targets increase, along with the input/output performance demands on the storage devices. |
|
Existing Management Repository |
Upgrade |
No |
Ensure that the existing, certified Oracle Database, which houses the Management Repository, already has a Management Repository configured, and that the Management Repository is compatible with Oracle Management Service 11g Release 1 (11.1). |
|
Database Partitioning Requirements |
Install and Upgrade |
No |
Ensure that the existing, certified Oracle Database has the Partitioning Option enabled (therefore, ensure that you install it into Oracle Database Enterprise Edition.) Installing and using the partitioning option in the Enterprise Manager repository does not add costs to customers when used solely by Enterprise Manager. To verify this, connect to the database as SYSDBA and run the following query: select value from v$option where parameter = 'Partitioning'; The result of this query should be VALUE=TRUE. No additional partitioning license is required for the database that houses the Management Repository. |
|
Database Partition Maintenance Requirements |
Upgrade |
No |
If the Enterprise Manager system that you are about to upgrade was shut down for a long period of time, then you will not have partitions created in the existing, certified Oracle Database, which houses the Management Repository, to load new data. Therefore, under such circumstances, do the following:
|
|
Database and Listener Status Requirements |
Install |
No |
Ensure that the existing, certified Oracle Database and its listener are running. |
|
Valid Objects Requirements |
Install, Upgrade, and Post requisite |
No |
Ensure that you do have only valid SYSMAN and SYS objects in the existing, certified Oracle Database.
|
|
DBMS Jobs and DBMS Scheduler Status Requirements |
Install and Upgrade |
Yes |
Ensure that you stop the DBMS Jobs and the DBMS Scheduler in the existing, certified Oracle Database. To do so, log in to the database as SYS:
|
|
Gather Statistics Job Status Requirements |
Install and Upgrade |
Yes |
Ensure that you stop the Gather Statistics job that is running in the existing, certified Oracle Database. To do so, log in to the database as SYS and run the following commands: For Oracle Database 10g (10.2.0.4) or higher: execute dbms_scheduler.disable('GATHER_STATS_JOB',TRUE); execute dbms_scheduler.stop_job('GATHER_STATS_JOB',TRUE); For Oracle Database 11g (11.1.0.7) or higher: execute dbms_auto_task_admin.disable('auto optimizer stats collection',null,null); |
|
User Privilege Requirements |
Upgrade |
No |
Ensure that SYSMAN and DBSNMP users have EXECUTE privileges to access the DBMS_RANDOM package in the existing, certified Oracle Database. To verify whether the users have EXECUTE privileges, run the following query. When you run this query for the SYSMAN user, the <user_account_name> must be SYSMAN, and when you run it for the DBSNMP user, the <user_account_name> must be DBSNMP. SQL> CONNECT AS SYS; SQL> SELECT grantee, grantor, owner, table_name FROM DBA_TAB_PRIVS WHERE table_name = 'DBMS_RANDOM' AND privilege = 'EXECUTE' AND grantee IN ( SELECT DISTINCT granted_role FROM DBA_ROLE_PRIVS START WITH grantee = '<user_account_name>' CONNECT BY PRIOR granted_role=grantee UNION ALL SELECT '<user_account_name>' FROM dual WHERE ROWNUM = 1 UNION ALL SELECT 'PUBLIC' FROM dual WHERE ROWNUM = 1 ) If these users do not have EXECUTE privileges, then grant them the privileges by running the following command. When you run this command for granting the privileges for the SYSMAN user, the <user_account_name> must be SYSMAN, and when you run it for the DBSNMP user, the <user_account_name> must be DBSNMP. SQL> GRANT EXECUTE ON DBMS_RANDOM TO <user_account_name>; |
|
Environment Variable Setting Requirements |
Install |
No |
Ensure that the environment variable ORACLE_HOME is set to the Oracle home of the OMS. For example, in Cshell, set it in the following way:
For example, in bash shell, set it in the following way: export ORACLE_HOME= /home/OraHomes/oms10g |
|
SUDO Configuration Requirements |
Install |
No |
Ensure that you configure SUDO in your environment. If you are unable to do so or if you have already upgraded any of the core components (OMS or Management Agent) without configuring SUDO, then follow the workaround described in My Oracle Support note 789363.1. |
|
User-Defined Metric Script Definition Requirement |
Upgrade |
No |
If you have any user-defined metric scripts in the Oracle home of a Management Agent that you are upgrading, then ensure that you manually copy all those scripts to another directory outside any Oracle home, and then update the user-defined metric definitions to reflect the new script location. This is because, after the Management Agent is upgraded, the user-defined metric scripts are not automatically copied to the new Oracle home. |
As one of the prerequisites, ensure that you set the initialization parameters as described in Table A-6 and Table A-7 for your existing, certified Oracle Database so that the Management Repository can be created. For information on how you can set these initialization parameters, see My Oracle Support note 1073647.1. All the initialization parameters apply to install and upgrade.
Important:
After you set the parameters, stop and start the database.Table A-6 Setting Fixed Initialization Parameters
