DataStage 7.5.1A Installation Issue

[attu]

After the DS 7.5.1A Installation we are facing some issues when we:

1. Run the command:

Code: Select all

$DSHOME/bin/dssh
An error has occurred during DataStage initialization
Please contact the system administrator
Error code:  4  22

2. Recycle DS Server:

Code: Select all

$DSHOME/bin/uv -admin -start
Unable to attach disk shared memory segment: Invalid argument
 
An error has occurred during DataStage initialization
Please contact the system administrator
Error code:  4  22

Error code:  4  22
DataStage Engine 7.5.1.2 instance "ade" has been brought up.
Starting JobMonApp

Why are we getting these error messages ? Do we need to reinstall DS again.

Thanks

Ray:

I checked the universe manual and looked at the error code

Code: Select all

4 22

4.System V semaphores are probably not configured in the kernel.

22. (EINVAL) Invalid argument. Some invalid arguments: dismounting a
nonmounted device, mentioning an unknown signal in signal, reading or
writing a file for which seek has generated a negative pointer. Also set by
math functions.

Is this issue related to the unix kernel settings?

Ray?

Could be. Did you ensure your kernel settings were at least at the minimum values noted in the Installation and Configuration Guide for your operating system?

[ArndW]

Yes, this is most likely because the minimum kernel settings specified in the installation guide were not set. If that is the case, changing those (and most likely rebooting) will get you up and running again.

hi,

the issue was resolved.
uvtemp was pointing to a non-existent filesystem in uvconfig file.
once we got that changed , the issue resolved.
thanks for all ur comments.
