trepctl shard

The trepctl shard command provides an interface to the replicator shard system definition system.

Usage

trepctl [ common-options ] shard [ options ]

Where:

Option	Description	Version
-delete [shard]	Delete a shard definition.
-insert [shard]	Add a new shard definition.
-list	List configured shards.

The replicator shard system is used during multi-site replication configurations to control where information is replicated.

Listing Current Shards

To obtain a list of the currently configured shards:

shell> trepctl shard -list
shard_id  master  critical
alpha     sales   true

The shard map information can also be captured and then edited to update existing configurations:

shell> trepctl shard -list>shard.map

Inserting a New Shard Configuration

To add a new shard map definition, either enter the information interactively:

shell> trepctl shard -insert 
Reading from standard input
...
1 new shard inserted

Or import from a file:

shell> trepctl shard -insert < shard.map
Reading from standard input
1 new shard inserted

Updating an Existing Shard Configuration

To update a definition:

shell> trepctl shard -update < shard.map
Reading from standard input
1 shard updated

Deleting a Shard Configuration

To delete a single shard definition, specify the shard name:

shell> trepctl shard -delete alpha
