This configuration variable detaches any file system from the runtime. The syntax is:
filesystem_DETACH n
where filesystem corresponds to the first five letters of the file system name and n is a non-zero value. Examples of file systems that may be detached using this feature are:
| Btrieve | BTRIE_DETACH |
| C-ISAM | C_ISA_DETACH |
| Informix | INFOR_DETACH |
| SQL Server | MSSQL_DETACH |
| ODBC | ODBC_DETACH |
| Oracle | ORACL_DETACH |
| RMS | RMS_DETACH |
| Sybase | SYBAS_DETACH |
| Vision | VISIO_DETACH |
The file systems may be detached only when the runtime is started, not during execution. If you detach all file systems, the runtime will terminate with an error message. For example, if you detach Vision with VISIO_DETACH on a standard runtime, the runtime will terminate with this message to std err: No file system available.
This feature automatically supports new file systems added to the runtime.
