DBMS_DEFER_QUERY: Performing Diagnostics and Maintenance
Occasionally, you may want to see details about deferred RPCs in the queue, such as what procedure and parameters are used. The DBMS_DEFER_QUERY package contains procedures to display this data.
How the Package Is Used
Typically, this package is used to assist in debugging errors and conflicts that have occurred during the execution of an RPC.
Installation and Access
The DBMS_REPCAT_QUERY package is created when the Oracle database is installed. The
dbmsdefr.sqlscript (found in the built-in packages source
directory) contains the source code for this package’s

catrep.sql, which must be run to install the advanced replication
packages. The wrapped SQL script
