DSXchange

Try to login with admin user i.e dsadm and create a test project.Then try to login with other user id.

Also check whether impersonation mode is enabled on Datastage server.

There are already 5 projects existing on the server.. and users were able to connect to the server till yesterday. Suddenly this problem started today. The server is running fine...

Impersonation mode is enabled on the server.

What could be the other reasons?

Is Datastage server running ? try restarting it.

yes, did so many times. DataStage server is running fine and it has started under dsadm user using av -admin -start. Please see the uv -admin -info

bash-2.03$ ps -ef |grep DataStage

Even we restarted the server and tried.. no luck..

Is there any way i can enable server logging and see whats wrong?

Can you quickly check if the Project Directories exist and the permissions on those directories are set up correctly.

Also check if the dstage group has been modified in the recent past.

Is it only from single machnie or from all the clinet pc?
Is it only to single project or to all the 5 projects?
If it is only to single project, you may need to check the integrity of you project files or you may even need to FIX some files.
If its only with one PC, reinstall the client software.

Another update, it looks like some problem happned in the project entries. When we ran the command ./dsadmin -listprojects , its not able to read the project entries.....

bash-2.03$ ./dsadmin -listprojects

ERROR: 81016

Status code = 81016

Where as the projects folders and files are there on the server..

bash-2.03$ pwd
/isvol1/GM/apps/IBM/Ascential/DataStage/home/dsadm/Ascential/DataStage/DSEngine/projects
bash-2.03$ ls -la

Where is teh configuration file in DaatSatge? It seems to be some entries are corruped. Any ideas?

That's because the command you needed was dsjob, not dsadmin. There is no such command as dsadmin.
