Deleting a Metadata Partition Using Fusion Middleware Control

14-28 Oracle Fusion Middleware Administrators Guide extensibility. Oracle Database enables you to deploy high-performing systems faster and more easily while utilizing the advantages of Unicode. Even if you do not need to support multilingual data today, nor have any requirement for Unicode, it is still likely to be the best choice for a new system in the long run and ultimately saves time and money and gives you competitive advantages in the long term. When storing the metadata in a SQL Server database, if the character set being considered for your locale is not case neutral, the case-sensitive collation must be selected during the creation of the database instance. Unicode support is the default when creating the MDS schema for SQL Server using RCU. You may overwrite this default to use non-unicode schema if that meets your requirements.

14.5 Purging Data

When the amount of data in Oracle Fusion Middleware databases grows very large, maintaining the databases can become difficult and can affect performance. In some cases, Oracle Fusion Middleware automatically purges data. In other cases, Oracle Fusion Middleware provides methods to manage growth, including scripts to purge data that can accumulate over time and that can affect performance. Many of the Oracle Fusion Middleware components provide scripts written as PLSQL procedures to purge the data. The scripts are located in: ORACLE_HOMEcommonsqlcomponent-name_purge_purgetype.sql For example, a script that purges logs for Oracle Business Process Management is located in: ORACLE_HOMEcommonsqlbpm_purge_logs.sql Table 14–2 provides pointers to information about purging data for Oracle Fusion Middleware components. Table 14–2 Purging Data Documentation Component Description Oracle Application Development Framework See Cleaning Up Temporary Storage Tables in the Oracle Fusion Middleware Fusion Developers Guide for Oracle Application Development Framework. Oracle Application Development Framework Business Components Use the following script to purge rows in the database used by Oracle ADF Business Components to store user session state and temporary persistent collections: ORACLE_COMMON_HOMEcommonsqladfbc_purge_ statesnapshots.sql The PS_TXN table is automatically purged. Oracle SOA Suite See Managing Database Growth in the Oracle Fusion Middleware Administrators Guide for Oracle SOA Suite and Oracle Business Process Management Suite. Oracle WebLogic Server: Oracle Infrastructure Web Services Use the following script to purge data if WS-RM uses a database store: ORACLE_COMMON_HOMEcommonsqlows_purge_wsrm_msgs.sql
