Deprecated feature: Configuring the massload utility
Procedure
- Change the Java virtual machine (JVM) heap size that is
used for the massload utility.
By default, the maximum amount of memory that is allocated to the JVM heap is 64 MB. If this heap size is not increased, the JVM can eventually run out of memory during the load process. The maximum amount of memory that is allocated to the Java heap can be varied by using the JVM
-mx
option in the Java command. If you are loading files that are more than 500 MB, then increase the JVM heap size to 512 MB or 1024 MB.To modify the JVM heap size for the massload utility:
- Open the following massload utility file in a text editor:
WC_installdir/bin/massload.sh
WC_installdir\bin\massload.cmd
WCDE_installdir\bin\massload.bat
- Change the JVM heap size to 1024 MB by specifying the
-Xms
and-Xmx
options of the Java command:- If the
-Xms
and-Xmx
parameters are already specified in the file, change the values to the heap size that you want. Ensure that you update all occurrences of-Xms
and-Xmx
. - If the
-Xms
and-Xmx
parameters are not specified in the file, change all occurrences of %JAVA_HOME%\bin\java in the utility command file to %JAVA_HOME%\bin\java -Xms1024M -Xmx1024M.
- If the
- Save your changes.
- Open the following massload utility file in a text editor:
- Optional: Change the directory for the massload
utility error log. By default, the massload utility writes the error
log to the following directory:
The directory where the input file resides.
WC_userdir/instances/ instance_name/logs
- Open the following massload utility file in a text editor:
- WC_installdir/bin/massload.sh
- WC_installdir\bin\massload.cmd
WCDE_installdir\bin\massload.bat
- Change error report location setting:
- If the
-Dcom.ibm.wcm.ErrorReporterDir
parameter is already specified in the file, change the directory to the new location for the massload utility error log. Ensure that you update all occurrences of-Dcom.ibm.wcm.ErrorReporterDir
. - If the
-Dcom.ibm.wcm.ErrorReporterDir
parameter is not specified in the file, change all occurrences of %JAVA_HOME%\bin\java %PM_ARGS% in the utility command file to %JAVA_HOME%\bin\java %PM_ARGS% -Dcom.ibm.wcm.ErrorReporterDir= error_log_directory.
Important: The directory that you specify must exist. The massload utility does not create the directory for you. If the specified directory does not exist, no error log file is produced. Additionally, if message logging is configured for the massload utility, aDirNotExististException
message is logged in the message log - If the
- Save your changes.
By default, the massload utility uses the Oracle thick JDBC client. To change the massload utility to use the Oracle thin JDBC client:
Note: The massload utility must be using the thick client during instance creation and the migration process. The bootstrap data gets processed during these processes.- Extract
DbConnectionImplIDProperty.properties
from the following file:- WC_installdir/lib/loader/oracle/dbconnect.zip
WCDE_installdir\workspace\wc\lib\loader\dbconnect.zip
- Open DbConnectionImplIDProperty.properties in a text editor.
- Locate the following text:
ConnectStringID = jdbc:oracle:oci8:@
Note: By default, the dbconnect.zip compressed file does not contain this text string. When thesetdbtype
utility script runs to switch the database type to an Oracle database, this compressed file is replaced. The compressed file is replaced with a version that contains the property information for Oracle databases. When this script runs, the dbconnect.zip compressed file with the Oracle information is copied from the following directory:- WC_installdir/wc.ear.ext/oracle/loader
- WCDE_installdir\wc.modules\loader\oracle
- Change the text to match the following text:
ConnectStringID = jdbc:oracle:thin:@
Depending on your system and massload needs, update the string value to use on the following specifications:Select the specification that matches the information that is passed into the massload utility. The information that is passed into the utility is appended to value of the ConnectionStringID key.- If you want to use a TNS name, for instance, a name that is defined in
tnsnames.ora, use:
ConnectStringID = jdbc:oracle:oci:@
On the command line when you use this ConnectStringID value, include the
-dbname tnsname
parameter and value specification. - If you are using the massload stand-alone utility, which is invoked by using
massload.bat, massload.sh, or
massload.cmd and want to use a SID specification use:
jdbc:oracle:thin:@
On the command line when you use this ConnectStringID value, include the
Along with invoking massload as a stanad-alone utility, you can invoke the massload utility as part of another operations, such as instance creation.-dbname host:port:SID
parameter and value specification. - If you want to use a Service specification, use:
jdbc:oracle:thin:@//
On the command line when you use this ConnectStringID value, include the
-dbname host:port/service
parameter and value specification.
The ConnectionStringID value is used only to determine which type of JDBC driver to use. For instance, if the value includes the keyword OCI, the OCI (thick) driver is used. Otherwise, the thin driver is used. The actual connection specification is derived from the information that is provided to the -dbname parameter. For instance, if -dbname tnsname is used, the OCI driver is automatically used. If -dbname host:port:sid or -dbname host:port/service is used, an attempt is made to connect to the service. If the connection attempt fails, an attempt is made to connect to the SID.
If you pass in a fully qualified JDBC URL, the URL is used unmodified to acquire the connection. The keyword specification in the ConnectionStringID is ignored.- If you use the following URL, the utility acquires a SID connection explicitly: jdbc:oracle:thin:@host:port:SID
- If you use the following URL, the utility acquires a service-based connection explicitly: jdbc:oracle:thin:@//host:port/service
- If you use the following URL, the utility uses the thick driver to acquire a connection to the given tns name: jdbc:oracle:oci:@tnsname
- If you want to use a TNS name, for instance, a name that is defined in
tnsnames.ora, use:
- Save your changes.
- Add the updated DbConnectionImplIDProperty.properties file to the WC_installdir/lib/loader/oracle/dbconnect.zip file. Overwrite the existing file in the archive.
- Copy dbconnect.zip and paste it
one directory level higher.For example, in this example, it would go in the WC_installdir/lib/loader folder.
