PLSQL_NATIVE_LIBRARY_SUBDIR_COUNT

Parameter type	Integer
Default value	0
Parameter class	Dynamic: ALTER SYSTEM
Range of values	0 to 232-1 (max value represented by 32 bits)

PLSQL_NATIVE_LIBRARY_SUBDIR_COUNT specifies the number of subdirectories created by the database administrator in the directory specified by PLSQL_NATIVE_LIBRARY_DIR.

When using the PL/SQL native compiler, Performance of file create/open operations is unacceptably slow if the number of files in a directory is very large. It is usually advisable to create subdirectories and use this parameter if the total number of different PL/SQL packages that may need to be compiled natively by all users of the database instance exceeds 10000.

The subdirectories should have names corresponding to zero-based decimal numbers, prefixed by d. For example, the database administrator can create 1000 subdirectories named d0, d1, ... d999, and set PLSQL_NATIVE_LIBRARY_SUBDIR_COUNT to 1000.
