Datastage Connectivity to multiple servers
I have one datastage servers having ip1 XXX:XXX:XXX:XXX
which has multiple projects such as DEV,QA,REG,PROD etc
now my company is replicating same environment on second server having Ip2
Everytime I have to add entry in host file for new server.
C:\WINDOWS\system32\drivers\etc\hosts file
# For example:
102.54.94.97 rhino1 # DS server1
38.25.63.10 rhino2 # DS server2
i know in unix or from cmd prompt i can give ping rhino1,rhino2 ,which will give me DS server1 or DS server2 ip.
but when i m getting connected through datastage designer or datastage director how do i know that that i m getting connectd to DS server1 or DS server2?

The way I read your entries is that rhino1 and rhino2 are two different hostnames. You could connect by entering actual IP addresses in place of host name on the login. If you do that then you can be connected to both servers in two clients at once.

Color me confused, nothing here shows as having the same or duplicate host names. As noted, one is named "rhino1" and the other "rhino2". Everything after the hash sign is a comment, by the way...qutesanju wrote:Here problem is
two servers has same host name

I tried by entring IP address,and it gives me error informationqt_ky wrote:The way I read your entries is that rhino1 and rhino2 are two different hostnames.

No Datastage credentials were found on the domain for the user(vqx8926) and datastage server ('102.54.94.97')
here hostname is same for ip(s)
102.54.94.97 rhino # DS server
38.25.63.10 rhino # DS server

Engine credentials are a totally separate issue. You have not configured credentials in the services tier for the DataStage engine in question, at least not for that particular user.

When connecting through Designer or Director, you provide the hostname (or sometimes the IP address) of the Services Tier (WebSphere Application Server) for the Information Server environment you're connecting to. DataStage projects within that environment are chosen by DataStage Engine Tier (hostname) and Project name. That is how you know which server you're connecting to.
If you have multiple IP addresses in your hosts file associated to the same name, more than likely the first listed will be chosen to resolve the hostname. Different operating systems may handle this differently, but I confirmed this on Windows 7, RedHat Linux and a 7-year-old SUSE Personal Linux 9.1 server. Your DataStage engine servers need to be properly configured with different hostnames. Once that is correct then you can focus on the engine credentials issue.

I'm certain you can take out the "more than likely" part of that statement. This is just a text file with absolutely no intelligence in it, it gets read from top to bottom and the first match wins.jwiles wrote:If you have multiple IP addresses in your hosts file associated to the same name, more than likely the first listed will be chosen to resolve the hostname.

What do you mean by "edit the hostname and project name"? Modify them within the login box? No...cannot be done.
When installed, an engine tier is registered with a services tier (a basic requirement of Information Server). Only the engine tiers registered to a services tier and the projects present in those engine tiers (i.e. created with DataStage Administrator) will be available to select from (in the drop-down box) when you attempt to login to the Information Server environment (a services tier server) with appropriate client software (Designer, Director, FastTrack, Administrator). If an engine server and/or project is not listed, it is not available in that environment.
