The Library is currently in the process of being upgraded from Oracle Database Version 126.96.36.199 to 188.8.131.52.
Demos are being upgraded to reflect the new Container paradigm as well as EBR (Edition Based Redefinition) and may contain references to CDBs, PDBs,
and other objects you may not be familiar with such as CDB_OBJECTS_AE: Welcome to 12c.
Also important ... there are rumors on the web about SPARC and Solaris being discontinued. Welcome to the age of fake news.
There is absolutely not a byte of truth to these irresponsible rumors.
As of Oracle Database 12c release 1 (12.1), SQL Apply processes have access to a context namespace called LSBY_APPLY_CONTEXT.
You can use the procedures provided in the DBMS_LOGSTDBY_CONTEXT package to set and retrieve various parameters associated with LSBY_APPLY_CONTEXT.
This is useful when writing skip procedures that are registered with SQL Apply using the DBMS_LOGSTBDY.SKIP and DBMS_LOGSTDBY.SKIP_ERROR procedures.
CREATE CONTEXT lsby_apply_context USING dbms_logstdby_context;
