RDFA Auto-recovery cannot be enabled

The RDFA Auto-recovery feature is enabled by default for new SRDF Groups starting in Magnolia code (10.2). You can disable this feature for an RDFG using the command:

symrdf -sid xxxx -rdfg ## set rdfa -autostart off

Once this feature is turned off, the command to turn it back on does not appear to work. For example:

C:\>symrdf -sid xxxx -rdfg 15 set rdfa -autostart on -nop

An RDF Set 'Attributes' operation execution is in
progress for RDF group 15. Please wait...

    SRDF/A Set Autostart (xxxx,0015).................................Started.
    SRDF/A Set Autostart (xxxx,0015).................................Done.

The RDF Set 'Attributes' operation successfully executed
for RDF group 15.

This behavior is working as designed. Once this feature has been disabled, it can only be reenabled by restarting the SRDF/A session. Auto-recovery stays inactive until the SRDF/A session restarts, even when autostart is enabled. Therefore, you must suspend and then resume the replication to see this value change for the group.

Workaround: You can reenable the RDFA Auto-recovery feature using the command:

symrdf -sid xxxx -rdfg 15 set rdfa -autostart on -nop

Once this has been enabled, you must suspend and then resume the replication to restart the Auto-recovery feature for this SRDF group:

C:\>symrdf -sid xxxx -f rdfg15.txt -rdfg 15 suspend -nop
