PLSQL_CCFLAGS provides a mechanism that allows PL/SQL programmers to control conditional compilation of each PL/SQL library unit independently.

Values:

<vi> has the form of an unquoted PL/SQL identifier. It is unrestricted and can be a reserved word or a keyword. The text is insensitive to case. Each one is known as a flag or flag name. Each <vi> can occur more than once in the string, each occurrence can have a different flag value, and the flag values can be of different kinds.
<ci> is one of the following: a PL/SQL boolean literal, a PLS_INTEGER literal, or the literal NULL. The text is insensitive to case. Each one is known as a flag value and corresponds to a flag name.

You can define any allowable value for PLSQL_CCFLAGS. However, Oracle recommends that this parameter be used for controlling the conditional compilation of debugging or tracing code. It is recommended that the following identifiers not be used as flag name values:

Names of Oracle parameters (for example, NLS_LENGTH_SEMANTICS)
Identifiers with any of the following prefixes: PLS_, PLSQL_, PLSCC_, ORA_, ORACLE_, DBMS_, SYS_
