ClearReplica Performance Alias Enhancers
In order to improve ClearTrigger performance for non-ClearReplica replicated VOBs in a ClearTrigger Region that has ClearReplica enabled you can prevent ClearTrigger from checking to see is “replication” is need by taking advantage of special ClearReplica Performance Alias Enhancers . The special aliases will limit which VOBs attempt to read the ClearReplica shipper_conf file or inform ClearReplica of data updates during modification of ClearTrigger data within certain VOBs; this improves ClearTrigger performance for those VOBs.
Only VOB entries (i.e. [/a_vob] [cm] ) or VOB:replica (i.e. [/a_vob:earth] [:atlanta] ) are valid or read in the alias, all other entry types are ignored.
This only affects “outbound” changes from the region. Any ClearReplcia “receiver” processes for the region are unaffected.
| ClearReplica Performance Alias | Purpose |
|---|---|
| #!cleartrigger_alias ABS_replicatation_active | Enables ClearReplica shipping processing only for the included VOBs. |
| #!cleartrigger_alias ABS_replicatation_inactive | Disables ClearReplica shipping processing for the included VOBs. |
If both aliases (i.e. ABS_replicatation_active and ABS_replicatation_inactive ) are placed in the clearbits file and a VOB is contained in both list then replication “inactive” for that VOB.
Examples of appropriate values are in the table below:
| ClearReplica Performance Alias Examples | Meaning |
|---|---|
| #!cleartrigger_alias ABS_replicatation_active [*qa] [\vobs\dev*] | VOBs matching the patterns are the only ones with outbound replication considered. |
| #!cleartrigger_alias ABS_replicatation_inactive [*cm] [*hr] | VOBs matching the patterns are not considered for outbound replication. |
