To monitor a monitoring target program, you need to install Oracle Client 32-bit and set the environment. Also, when executing the jpcconf inst setup command, set each item as follows:
  • oracle_home
    Specify the Oracle home for Oracle Client 32-bit.
  • oracle_version
    Specify the version of Oracle Client 32-bit.
  • net_service_name
    Specify the net service name set for Oracle Client 32-bit.
For the net service name set in Oracle Client 32-bit, specify the net service name for connecting to the monitored instance of Oracle Database.
If Oracle Client 32-bit has not been installed and the environment has not been configured, and you specify an Oracle Database in which Oracle Client 32-bit is not installed or specify ORACLE_HOME of Oracle Client 64-bit for oracle_home in the instance information and you then start PFM - RM for Oracle, the message KAVL18020-E is displayed.

#2
If PFM - RM for Oracle uses the client library of an Oracle Database in which Oracle Client 32-bit has been installed, specify the Oracle home folder of the Oracle Database.

#3
To change a user, use the following procedure:
  1. Delete the objects created by the user you want to change.
  2. Register new objects as the new user.
Performance data is not deleted when a user is changed.
For details about how to delete objects, see 2.3.2(1)(c) Deleting the objects registered in the Oracle Database. For details about how to register objects, see 2.1.4(3)(c) Registering objects in the Oracle Database.

#4
If the expiration date is set on oracle_passwd, once the password is out of date connections to Oracle fail so that PFM - RM for Oracle cannot collect the performance information. In order to avoid connection errors, perform either of the following procedures before the password is expired:
  • Unset the expiration date of the password
  • After updating password, execute the jpcconf inst setup command to update oracle_passwd.
Note that the Oracle DEFAULT profile is applied to the Oracle account created by mk_rmus.sql.

#5
Specify in advance the network service (such as tnsnames.ora) of the Oracle Client used by PFM - RM for Oracle.
Configure the network service definition (such as listener.ora) and run the listener process in advance.
When monitoring Oracle Database instances in an Oracle RAC configuration, set up the PFM - RM for Oracle so that it monitors Oracle Database instances on each node. For details about how to set up, see the Oracle documentation.
Note that the location of tnsnames.ora must be:
 
oracle_home\network\admin
If tnsnames.ora is located on other folder, PFM - RM for Oracle cannot connect to Oracle.

#6
To obtain each piece of Oracle segment-related information, PFM - RM for Oracle searches Oracle's static data dictionary views DBA_SEGMENTS. If a large number of segments (more than hundreds of thousands) exist for Oracle, information collection requires a significant amount of time. As such, when a large number of segments exist, and the information listed in the following table no longer needs to be collected, set the sql_option to Y during operation.

Physical Reads Always set to 0 because it is a delta item.
Physical Writes Always set to 0 because it is a delta item.

#7
If the field format for each record is float or double, since the data is a floating-point number, it may be rounded depending on the specified value.
Example:
When numeric_10 is set to 32767, it may be displayed as 32760.

#8
When localtemp_option is set to Y, collect free space of the locally managed temporary tablespace and information about the extents from v$temp_extent_pool of the dynamic performance view. The displayed values of the size of free space are calculated from the size of the used space.
When localtemp_option is set to N, collect free space of the locally managed temporary tablespace and information about the extents from v$temp_space_header of the dynamic performance view. The displayed values of the size of free space are the size of the unallocated space. Since the allocated space is not freed until the temporary tablespace is reconstructed or recreated, the displayed values of free space do not increase until the space is freed.
When issuing query to v$temp_extent_pool view, the Oracle instance goes to sleep. Since this may have effect on the performance of the Oracle instance, you need adequate consideration before localtemp_option is set to Y. For details, see your Oracle documentation.

#9
When undospace_option is set to N, the size of the unallocated space is collected as the amount of free space in the UNDO tablespace. Space in the UNDO tablespace that becomes available because its retention period has expired is treated as allocated space until it is released.
When undospace_option is set to Y, the size of the free space is collected as the amount of free space in the UNDO tablespace. Space of the UNDO tablespace that becomes available because its retention period has expired is included in the size of the free space.
The following table shows the fields whose values change depending on the specification of the undospace_option:

Performance data is collected within the scope of 7-bit ASCII characters, likely resulting in unreadable characters.

For any other combination, performance data is collected within the scope of 7-bit ASCII characters, likely resulting in unreadable characters.
When you specify an invalid character code set for the nls_lang instance information, the message KAVL18302-W with errcode 12705 is output, and the connection with Oracle will fail.
In the following cases as well, unreadable characters might occur in the performance data:
  1. The Oracle column length is exceeded.
    If you store data that exceeds the Oracle column length, the last character might become unreadable. If you use PFM - RM for Oracle to collect data in Oracle and that data contains unreadable characters, the last character of the performance data will be unreadable.
  2. The field size of PFM - RM for Oracle is exceeded.
    PFM - RM for Oracle collects performance data of the record field size from Oracle. Therefore, if Oracle contains data that exceeds the field size, the last character of the performance data might be unreadable. The following table lists the applicable fields:
    Recode name Field name Filed size (unit: bytes)
    Parameter Values(PD_PDP) Value 512
    SQL Text(PD_PDSQ) Explain Plan 30,000
    SQL Text 30,000

Use the jpcconf inst list command to check the instance name. To update an instance environment, use the jpcconf inst setup command.

Updating an instance environment involves the steps described below. To update multiple instance environments, repeat the procedure for each instance environment.

To update an instance environment:

  1. Find the instance name.
    Execute the jpcconf inst list command specified with the service key that indicates PFM - RM for Oracle.
     
jpcconf inst list -key RMOracle
    If the specified instance name is SDC, the command displays SDC.
  2. If the PFM - RM for Oracle service is active in the instance environment that is to be updated, stop the service.
    For details about stopping services, see the chapter on starting and stopping Performance Management in the Job Management Partner 1/Performance Management User's Guide.
    If the service is still active in the instance environment that is to be updated when you execute the jpcconf inst setup command, a confirmation message is displayed to enable you to stop the service. If you stop the service, update processing resumes; if you do not stop the service, update processing is canceled.
  3. Execute the jpcconf inst setup command specified with the service key that indicates PFM - RM for Oracle and the instance name.
    For example, if you are updating the instance environment for the PFM - RM for Oracle with instance name SDC, execute the following command:
     
jpcconf inst setup -key RMOracle -inst SDC
  4. Update the instance information for Oracle.
    Enter the information shown in Table 2-29 in accordance with the command's instructions. The current settings are displayed (except for the value of oracle_passwd). To use the displayed value, press the Enter key. When you have finished entering information, the instance environment is updated.
  5. Restart the service in the updated instance environment.
    For details about starting services, see the chapter on starting and stopping Performance Management in the Job Management Partner 1/Performance Management User's Guide.

For details about commands, see the chapter on commands in the manual Job Management Partner 1/Performance Management Reference.

  3. Unreadable or lack of characters in deferent between database character set of the Oracle and nls_lang instance variable of the PFM - RM for Oracle.
    A data of 2 bytes on the basis of Oracle may be collected at 3 bytes when you set AMERICAN_AMERICA.AL32UTF8 in nls_lang and a database character set for the monitoring is not UTF-8. Therefore, if performance data takes from ORACLE that exceeds the field size, the last character of the performance data might be unreadable. The following table lists the applicable fields:

When undospace_option is set to N, the size of the unallocated space is collected as the amount of free space in the UNDO tablespace. Space in the UNDO tablespace that becomes available because its retention period has expired is treated as allocated space until it is released.
When undospace_option is set to Y, the size of the free space is collected as the amount of free space in the UNDO tablespace. Space of the UNDO tablespace that becomes available because its retention period has expired is included in the size of the free space.
The following table shows the fields whose values change depending on the specification of the undospace_option:

Use the jpcconf inst list command to check the instance name. To update an instance environment, use the jpcconf inst setup command.

Updating an instance environment involves the steps described below. To update multiple instance environments, repeat the procedure for each instance environment.

To update an instance environment:

  1. Find the instance name.
    Execute the jpcconf inst list command specified with the service key that indicates PFM - RM for Oracle.
     
jpcconf inst list -key RMOracle
    If the specified instance name is SDC, the command displays SDC.
  2. If the PFM - RM for Oracle service is active in the instance environment that is to be updated, stop the service.
    For details about stopping services, see the chapter on starting and stopping Performance Management in the Job Management Partner 1/Performance Management User's Guide.
    If the service is still active in the instance environment that is to be updated when you execute the jpcconf inst setup command, a confirmation message is displayed to enable you to stop the service. If you stop the service, update processing resumes; if you do not stop the service, update processing is canceled.
  3. Execute the jpcconf inst setup command specified with the service key that indicates PFM - RM for Oracle and the instance name.
    For example, if you are updating the instance environment for the PFM - RM for Oracle with instance name SDC, execute the following command:
     
jpcconf inst setup -key RMOracle -inst SDC
  4. Update the instance information for Oracle.
    Enter the information shown in Table 2-29 in accordance with the command's instructions. The current settings are displayed (except for the value of oracle_passwd). To use the displayed value, press the Enter key. When you have finished entering information, the instance environment is updated.
  5. Restart the service in the updated instance environment.
    For details about starting services, see the chapter on starting and stopping Performance Management in the Job Management Partner 1/Performance Management User's Guide.

For details about commands, see the chapter on commands in the manual Job Management Partner 1/Performance Management Reference.
