Metadata | Techartifact

In Weblogic for exporting metadat we use various command like

-> importMetaData – Imports metadata for an application.

-> exportMetaData – Exports metadata for an application.

-> deleteMetaData – Deletes the metadata in the application repository.

-> purgeMetaData – Purge metadata.

-> deleteMetadata – Deletes the selected documents from the application repository. When this command is run against repositories that support versioning (that is, database-based repositories), delete is logical and marks the tip version (the latest version) of the selected documents as “deleted” in the MDS repository partition.

example – wls:/weblogic/serverConfig> deleteMetadata(application=’mdsapp’,server=’server1′, docs=’/mypackage/*’)

-> exportMetadata -Exports application metadata. Use this command and the importMetadata command to transfer application metadata from one server location (for example, testing) to another server location (for example, production).

example – wls:/weblogic/serverConfig> exportMetadata(application=’mdsapp’,server=’server1′,toLocation=’/tmp/myrepos’,docs=’/**’)

-> importMetadata– Imports application metadata. Use the exportMetadata command and this command to transfer application metadata from one server location (for example, testing) to another server location (for example, production).

example – wls:/weblogic/serverConfig> importMetadata(application=’mdsapp’, server=’server1′,fromLocation=’/tmp/myrepos’,docs=”/**”)

-> purgeMetadata– Purges the older (non-tip) versions of unlabeled documents from the application’s repository. All unlabeled documents will be purged if they are expired, based on Time-To-Live (the olderThan argument). This command is applicable only for repositories that support versioning, that is, database-based repositories.

example – wls:/weblogic/serverConfig> purgeMetadata(‘mdsapp’, ‘server1’, 10)

update metadata in webcenter-config.xml –

Now Lets take an example of changing an metadata for webcenter application. So first we export in some temprary location then we make some changes.Then again we import from temp location to specified location.

-> Go to Middleware home/WebCenter Installation directory/common/bin and run wlst.sh (unix) or wlst.cmd(windows)

-> connect(‘weblogic’,’weblogic1′,’locahost:7001′) or give secure files path connect(userConfigFile=’/oracle/config.secure’, userKeyFile=’/oracle/key.secure’, url=’localhost:7001′)
see how to generate secure file

Then export the current configuration by running the following command in WLST command line. Set the toLocation to some “temporary location”.
->exportMetadata (application=’webcenter’, server=’WC_Spaces’, toLocation=’/tmp/Metadata’, docs=’/oracle/webcenter/webcenterapp/metadata/webcenter-config.xml’)

-> Change XXX parameter to XX MB in /oracle/webcenter/webcenterapp/metadata/webcenter-config.xml file.

-> Then import the file back to WebCenter Spaces server following the below mentioned command line.

importMetadata(application=’webcenter’, server=’WC_SpacesXXX’, fromLocation=’/tmp/Metadata’, docs=’/oracle/webcenter/webcenterapp/metadata/webcenter-config.xml’)

-> exit();

Requirement- For one of custom metadata type of memo’s size 2000 and want to increase to 4000

Solution- Log into your content server with administrative privileges or as weblogic and select Admin Server from the Administration menu. Click the button for the instance you will be working with and then select General Configuration from the left hand menu. Add this configuration setting:

MemoFieldSize=4000

increasing size for single metadata
If you just want to increase size for one meta data then you can use this, you can again use config.cfg or go through the admin server to add a configuration setting something like this:

xSingleMetadatafield:maxLength=1024

after doing this , you have to alter the table schema for existing metadata like

ALTER TABLE 
docmeta 
MODIFY (xdescription varchar2(4000 char));

Then

-> Click on admin applet.
-> Click on Repository Manager.
-> Click on third tab ‘Indexer’tab and click on Collection Rebuild Cycle.
-> Then click on Automatic Update Cycle
-> Close and restart UCM server.
