External AW-HDS Server installation.

[Ritesh Desai]

Hi folks,

request your guidance regarding deployment.

In continuation with discussion on this https://supportforums.cisco.com/discussion/13095941/external-aw-hds-server-sizing,

I got a doubt on configuration, I'll be deploying Packaged CCE Side A and B as per design documents. Additionally for reports retention policy of 7 years, I will be installing AW-HDS on external server.

• Do I need to install Side B and Ext AW-HDS on single server single instance (Cisco Data Server).
• Will my Side A and Side B data will replicate to Ext AW-HDS Server?
• Will replication happen auto or job needs to be scheduled for replication activity.
• CDR and HDS data will be stored for 7years?

How should I proceed, I have gone through PCCE installation and configuration guide. Please guide...

regards,

Ritesh Desai.

PCCE Supports up to two External AW-HDS-DDS for third party reporting and extended data retentions.

You can not install this external data servers on same PCCE hardware, you have to use different hardware to get it done.

You can install the AW-HDS-DDS in the same way you install it for UCCE and point them to your PCCE router and logger and data will be replicated out of box if replication is enable.

if you plan to use two external AW-HDS-DDS you can point one of them to side A and other to Side B of central controller,

HDS will not store cucm CDR records, it will only store historical data obtained from Logger and till what time it stores is going to be dependent on how you have done the sizing.

Chintan,

Thanks for clarifying...

Can we use Single Ext. AW-HDS-DDS Server and point to Side-A and Side-B?

Do we need additional configuration on pointing of database?

when you install AW-HDS-DDS through web setup, it will ask you the IP/Hostname for both side of Central controller node (Router A and B, and Logger A and B).

but there will be radio button for Central controller preferred side (Side A or Side B).

whatever preferred side you choose, the AW-HDS-DDS will try connect to that side for config, real time and historical data.

Now there little catch here:

1) configuration and real-time data:

Configuration and real-time data will switch there feed to other side if connection to preferred Central controller side is down or having some problem. so you are saved here.

2) historical data: 

The HDS will have historical feed activated with only one side of logger, whatever you defined under preferred side of CC.

so if the connection to preferred side is down, the historical data replication stops until the preferred side logger comes up. once the logger is up, the historical data will be copied to HDS server. but if down time is long, then there are chances of data holes in HDS database.

so its always good to have two external AW-HDS-DDS pointed to two different side of CC, so if you loose data at one site you still have good copy of data at other side.

Chintan,

Ok... Thanks for clarification.

Chintan,

sorry for long delay. I've question here.

1) configuration and real-time data:

Configuration and real-time data will switch there feed to other side if connection to preferred Central controller side is down or having some problem. so you are saved here.

Am confused here. Does your statement says for Central Controller in HA Mode. Will you please elaborate...

[Chintan Gajjar]

Central Controller always runs in HA mode, infact all component of ICM except AW run in HA mode(some is active-standby and some in active-active).

Chintan,

My understanding says, data will be duplicated like, Call data on Data Server Side A and Central Controller Side A.

What if I do like this?

Instead of setting-up Central Controller, deploy Win 2012 with SQL and schedule job which pulls data from Data Server Side A & Side B and place it on SQL DB Server. Execute job in lean hours or non-production hours.

Also, configure RAM and CPU utilization for SQL 2014 will create any issue.

suggestions please...

Ritesh Desai.

Ritesh,

What do you mean by 

//My understanding says, data will be duplicated like, Call data on Data Server Side A and Central Controller Side A.//?

and 

//Instead of setting-up Central Controller//

i guess you are having misunderstanding of UCCE and PCCE terminology.

PCCE is nothing but same product as UCCE but deployed in particular style to support only 1000 to 1500 agents on pair of server. but it uses same media and component which are used to deploy UCCE.

Central Controller is terminology used to address router and logger on same side in UCCE and PCCE and ICME etc.

so in PCCE when you install Call Server and Data server components on each side, you will obviously have Central controller components installed (Logger and Router on Side A and B), so you don't have to deploy it separately.

Now the only thing left is setup external AW-HDS-DDS on separate server with proper sizing and point it to Central controller (PCCE SIDE A or B Router and Logger) and you will have data replication established from Logger on whatever side you prefer.

at any point of time Healthy PCCE or UCCE Logger database have identical data and they are always in synch.

You don't need to setup any other SQL job and probably those will not be supported also on PCCE logger database.

Does that answer your question?
