Oracle11gRAC安装JVM组件

安装前检查：

检查角色：

select * from dba_roles where ROLE in ('JAVAIDPRIV','JAVAUSERPRIV');

检查DBMS_JAVA：

select * from dba_procedures where OBJECT_NAME= 'DBMS_JAVA';

检查组件：

-- Start of File full_jvminst_ceshi.sql
spool full_jvminst_ceshi.log;
set echo on
select obj#, name from obj$
where type#=28 or type#=29 or type#=30 or namespace=32;
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
set echo off
spool off
exit
-- End of File full_jvminst_ceshi.sql

安装JVM组件：

方式一（图形化安装）

Add the Oracle JVM component using the Database Configuration Assistant Utility

a. Start the Database Configuration Assistant and Click Next at the Welcome screen.

预计完成时间： 半个小时左右，视数据库的性能安装时间有所偏差

方式二（执行脚本安装）

Manually Add the JVM Component by executing the initjvm.sql script.

The following steps need to be executed precisely as listed below to ensure that they complete successfully:

a. Verify the following system requirements are available:

The Shared Pool has at least 96Mb of free space.
The Java Pool has at least 50Mb of free space
The SYSTEM tablespace has at least 70Mb of free space
The SYSTEM RBS has at least 100Mb of free space

The initjvm.sql script in 11g will check these resources are available when it is run, and if they aren’t available the execution of the script will terminate with an error indicating which resource needs to be increased.

b. Shutdown the instance and then create and run the following sql script from a new sqlplus session:

-- Start of File full_jvminst.sql
spool full_jvminst.log;
set echo on
connect / as sysdba
startup mount
alter system set "_system_trig_enabled" = false scope=memory;
alter database open;
select obj#, name from obj$
where type#=28 or type#=29 or type#=30 or namespace=32;
@?/javavm/install/initjvm.sql
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
@?/xdk/admin/initxml.sql
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
@?/xdk/admin/xmlja.sql
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
@?/rdbms/admin/catjava.sql
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
@?/rdbms/admin/catexf.sql
select count(*), object_type from all_objects
where object_type like '%JAVA%' group by object_type;
shutdown immediate
set echo off
spool off
exit
-- End of File full_jvminst.sql

c. Once the database has been restarted, resolve any invalid objects.

This can be performed by running the utlrp.sql script e.g.:

@?/rdbms/admin/utlrp.sql
