IPCC Express with High Availability

[shivkumargadad]

Hi,

We have customer who purchased two servers for IPCC Express 4.x

installation with High Availability,

does any body have proper procedural document. for installation.

1. Is CRS A and CRS B both server will be having any connectivity

between them through crossover cable for redundancy.

2. While installing CRS B server does it going to use the same profile

name what CRS A had used,

3. Do i need to configure the same configuration again what i configured

in CRS A.

Regards,

Shivkumar

What does your CRS AppAdmin License information page show (a link in the Control Centre pages)?

The logs are in C:\Program Files\wfavvid\logs

Hi,

There was problem with License, I uploaded the Correct License on the CRS A server and restarted the Engine, then tried uploading the license on the CRS B server but that was still there as Addon server, I reintsalled the CRS B server installed SQL then it run in to Server setup and joined to the cluster.

i just activated all the componenets, started working and all the configuration got replicated.

After reboot SQL replication happened automatically i didn't go to manually CRS update tool.

Every thing working fine including the failover.

Thanks

Hi,

I am using Extension mobility,and IP Agent Phone service for agents to login,

I have two queries here,

1. Here every agent has to login to Extension mobility and then IP Agent Phone service. Is there any way where once the user login to Extension mobility should make him to login IP Agent phone also automatically.

2. As we were using IP Agent phone service, We have defined IP Agent Service as below in call Manager Publisher server.

http://10.36.0.225:6293/ipphone/jsp/sciphonexml/IPAgentInitial.jsp

Here in service i have defined only the CRSA server ip address in the Service,

what if my CRSA server goes down and how the agents will be logging in to IP Agent Phone Service. does it automatically takes over the CRSB server. and Agents will be Ready in IP Agent Phone Service.

do i need to mention CRSB server IP Address next to the CRSA server ip address in IP Agetn Phone Service URL.

You will need to define two IPPA services . One for each IPCC Server. On a failure IPPA does not function like CAD . CAD automatically failsover in one minute but IPPA does not. Agents have to manually login to the secondary service.

I hope this helps!!!

Thanks,

Hi

Thanks for the information,

We have this setup newly installed its pages

are opening very slowly, like if i click Scrip management it takes almost 40 seconds to open, any page in CRS appadmin, in both the CRS A and CRS B sserver ,

does any body knows the reason.

Both of the CRS Servers are there in one workgroup even other two Call Managers also there in the same workgroup.

Rebooted both the servers , still its very slow. there's not cpu or memory utlization.

[mmelbourne]

I'd first check name resolution. Also, in the browser on the CRS boxes, I've seen "automatically detect" proxy settings enabled which will slow down the first connection, but subsequent requests are usually OK.

Are the servers specified in LDAP configuration reachable (particularly the first in the list).

[shivkumargadad]

I have edited the hosts files in both CCM's and both CRS server about the Hostname and IPAddress,

i am able to ping hostname from any server to any server.

here when i open crsadmin page first time it comes fast and logins also fast, but when i click Script management option or Prompt management it take about 20 seconds

In CRS LDAP Information both CCM's IP's mentioned.

[shivkumargadad]

Hi

I have checked the LDAP Configuration in CRS Server both the CCM's ip address is mentioned.

The Master CRSA server has become very slow in operating the Appadmin page, when i open the Appadmin page it comes very fast but if i go for any script uploading it opens the page after 20 seconds, and even if i click the Prompt Management its very slow takes about 20 seconds any options if i click taking lot of time,

I have edited the hosts file, and both the CRS servers and CallManagers are there in one workgroup.

and all these servers are terminated on one 2950 switch, any server to any server ping response is about 10ms delay is there, and when i checked the CPU Utilization and Memory Utilization is its consuming very less,

both the servers i rebooted once, now the CRSA server is Master,

Could you tell me why its happening.

we have hardly configured about 3 scripts and about 10 agents,

Regards,

Shivkumar

Are you opening the CRS AppAdmin pages on the master server? Which version of IPCC Express? Does it make any difference if the standby server is disconnected? It sounds like the issue is with the Repository (where script, prompts and documents are stored). I suggest you raise a TAC case with your support provider.

[shivkumargadad]

Yes I am opening CRS appadmin pages on the master server, its 4.0.5 version of CRS Server, I tried failover test and tried calling the ctiroutepoint i didn't faced any problem, I am storing the Scripts in

C:\Progrmfiles\wfavvid\Scripts\user\default.

and Prompts i am storing in

C:\Progrmfiles\wfavvid\prompts\user\default.

do i need to store them in

C:\Progrmfiles\wfavvid\Scripts\system\default

[mmelbourne]

Script and prompts (and documents) need to be uploaded to the Repository using the AppAdmin interface, rather than storing them in specific locations.

[shivkumargadad]

I have uploaded the prompts using appadmin page, but the ivr script when i created i stored in the below path.

c:\programfiles\wfavvid\scripts\user\default

Do i need to do something here,

and when application manager service, and Manager manager service in partial service what needs to be done.

Hi there,

I have a problem with CRS database configuration. To use DB Read step in CRS Editor, you need to configure a database in CRS. Before CRS Database configuration, need to create a Database Source Name (DSN) in CRS server (in Data Source ODBC).

I have a DSN created in CRS A server, and created a CRS Database subsystem. On CRS A, database subsystem with CRS Engine has been started. However, the CRS B's database subsystem is not started. Failure message in the log was "No DSN Configured".

My question is: when create DSN in CRS A, do I also need to create the same DSN in CRS B? Is there a way that these two servers replicate their DSN information? If only configured in CRS A, and CRS A is down, then CRS Editor connecting to CRS B will not be able to find the database in DB Read. I guess I miss something in my configuration for two CRS servers. Please help.

[mmelbourne]

I think you probably need to recreate the DSNs on CRS B, if you're sure everything else has been replicated and the Database Subsystem is still out of service, It's an interesting point and not one I've seen documented anywhere. I wonder whether the same is true of the e-mail Subsystem?

[wenqianyu]

Yes, you are right. As soon as I configured DSN on CRS B, then the Database Subsystem under CRS Engin in CRS B became active. Is there any way to configure DSN on one CRS server and automatically replicate to the other?
