Managing CDS Directories
18.2.1 Before You Create a Replica
Before you try to create a replica, verify that the clearinghouse containing the master
replica of the directory you intend to replicate is running and reachable. To verify that
this condition is satisfied, follow these steps:
1. For the directory that you intend to replicate, use the directory show command to
display the directories attribute values and look at the CDS_Replicas attribute.
The value of this attribute shows the names of the clearinghouses that currently
store a replica of the directory. For example:
dcecp> directory show /.:/sales
{RPC_ClassVersion {01 00}}
{CDS_CTS 1994-08-12-09:52:30.396-04:00I0.000/00-00-c0-f7-de-56}
{CDS_UTS 1994-08-12-09:52:31.506-04:00I0.000/00-00-c0-f7-de-56}
{CDS_ObjectUUID a37d84d0-b5dc-11cd-8ffe-0000c0f7de56}
{CDS_Replicas
{{CH_UUID ce7ed810-b5db-11cd-8ffe-0000c0f7de56}
{CH_Name /.../Chicago1/Chicago1_CH}
{Replica_Type Master}
{Tower {ncacn_ip_tcp 130.105.5.16}}
{Tower {ncadg_ip_udp 130.105.5.16}}}}
{CDS_AllUpTo 1994-08-12-09:52:31.566-04:00I0.000/00-00-c0-f7-de-56}
{CDS_Convergence medium}

{extension +1-00:00:00.000I0.000}}
{myname /.../Chicago1/sales}}}
{CDS_DirectoryVersion 3.0}
{CDS_ReplicaState on}
{CDS_ReplicaType Master}
{CDS_LastSkulk 1994-08-12-09:52:31.566-04:00I0.000/00-00-c0-f7-de-56}
{CDS_LastUpdate 1994-08-12-09:52:31.506-04:00I0.000/00-00-c0-f7-de-56}
{CDS_RingPointer ce7ed810-b5db-11cd-8ffe-0000c0f7de56}
{CDS_Epoch a3df2a50-b5dc-11cd-8ffe-0000c0f7de56}
{CDS_ReplicaVersion 3.0}
2. With this information, use the directory show command with the
-clearinghouse and -replica options to verify that you can get a
response from the clearinghouse that stores the master replica. For
