Ug. An upgrade is the simplest thing in the world. Other than taking a backup, as you did, the process is to simply install the new version right over the top of the old one. It handles everything automagically. Did you uninstall the old version or do something that caused the Projects to need to b...

Datastage Version:How toupgrade from 7.5.1 server to 7.5.2?

I am converting our datasstage ser5ver from 7.5.1A to 7.5.2 and the method I am following is take a backup from the Datastage Manager and importing back the Jobs after 7.5.2 server and corresponding projects are created. This seems to be working good except for the Version Control Project. If I do t...

Having restored DSEngine and the projects, try reinstalling the server. This should go into maintenance mode. If there is a hidden file in the root directory its pathname would be .dshome - check for hidden files in the root directory ls -al /.* -- I checked , there is no file like that in root dir...

If you go into the UV shell and issue the command "COUNT DS_JOBS" what do you get? Perhaps your restore settings were such that existing files in the project directories were not overwritten. I dont have project any more , as I was restoring both server and projects again in a hope that i...

If you re-installed the DataStage server, then created empty projects with the same names and absolute locations as before, then overwrote those directories from a restore you should have been able to see the jobs. If you attach to the directory from UNIX you should see a number of files - i.e. RT_...

Ok, that message means that your DSParams file is actually in the project directory. Can you explicitly set the permissions on the file to allow all access to everyone and see if your error message goes away? I changed and tried to login, I get the same message while logging in . Even the different...

Does ds_jobs , ds_jobobjects hash files /tables are supported (i.e. has the correct design time information what it used to contain pre 8.0 versions ) in datastag...
