Dynamic API Interaction

The following SQL built-in procedures can enable VSS Writer support:

call fc_set_sysconfig('vss_writer', 'YES');

call fc_set_sysconfig('diagnostics', 'VSS_WRITER');

The SetConfiguration(), ctSETCFG() API function can be used to change VSS configuration dynamically.

Examples

If the FairCom DB VSS writer is not running, the following call starts it:

ctSETCFG(setcfgVSS_WRITER, "YES");

If the FairCom DB VSS writer is running, the following call stops it:

ctSETCFG(setcfgVSS_WRITER, "NO");

The following call enables VSS writer diagnostic logging:

ctSETCFG(setcfgDIAGNOSTICS, "VSS_WRITER");

The following call disables VSS writer diagnostic logging:

ctSETCFG(setcfgDIAGNOSTICS, "~VSS_WRITER");
