# 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. |
