I m going to work on a POC and would like know some details around these features. As the name suggests if DataStage client application is left inactive for specified inactivity time out period connection terminated and corresponding dsapi slave process ends.

There are definitely some nifty new features tacked on suite from standpoint of data governance metadata management administration but this post will review just DataStage.

So basically in node1 and node2 , all the resources are shared. This means that the disk and scratch disk specified is actually shared between those two logical nodes. Node3 on the other hand has its own disk and scratch disk space. Pools Pools allow us to associate different processing nodes based on their functions and characteristics.
So if you see an entry other entry like node0 or other reserved node pools like sort,db2,etc.. Then it means that this node is part of the specified pool. A node will be by default associated to the default pool which is indicated by. Now if you look at node3 can see that this node is associated to the sort pool.
This will ensure that that the sort stage will run only on nodes part of the sort pool. Resource disk - This will specify Specifies the location on your server where the processing node will write all the data set files. As you might know when Datastage creates a dataset, the file you see will not contain the actual data.
The dataset file will actually point to the place where the actual data is stored. Now where the dataset data is stored is specified in this line.
Resource scratchdisk The location of temporary files created during Datastage processes, like lookups and sorts will be specified here. If the node is part of the sort pool then the scratch disk can also be made part of the sort scratch disk pool. This will ensure that the temporary files created during sort are stored only in this location. If such a pool is not specified then Datastage determines if there are any scratch disk resources that belong to the default scratch disk pool on the nodes that sort is specified to run on.
If this is the case then this space will be used. A basic configuration file for a single machine, two node server 2-CPU is shown below. The file defines 2 nodes node1 and node2 on a single dev server IP address might be provided as well instead of a hostname with 3 disk resources d1 , d2 for the data and Scratch as scratch space. The sample configuration file for a cluster or a grid computing on 4 machines is shown below. The configuration defines 4 nodes node[] , node pools n[] and s[ , resource pools bigdata and sort and a temporary space.
Resource disk : Here a disk path is defined. The data files of the dataset are stored in the resource disk. Resource scratch disk : Here also a path to folder is defined. This path is used by the parallel job stages for buffering of the data when the parallel job runs.
Datastage Errors and Resolution You may get many errors in datastage while compiling the jobs or running the jobs. If you are trying to read the file, which was not there with that name. This will occur when data type mismaches occurs in the jobs.
When checking operator: A sequential operator cannot preserve the partitioning of the parallel data set on input port 0. Solution:I resolved by changing the preserve partioning to 'clear' under transformer properties. Syntax error: Error in "group" operator: Error in output redirection: Error in output parameters: Error in modify adapter: Error in binding: Could not find type: "subrec", line Solution:Its the issue of level number of those columns which were being added in transformer.
Their level number was blank and the columns that were being taken from cff file had it as Added the level number and job worked. As target field is Decimal. By default the output from aggregator output is double, getting the above by using above function able to resolve the warning.
Problem Abstract Jobs that process a large amount of data in a column can abort with this error: the record is too big to fit in a block; the length requested is: xxxx, the max block length is: xxxx. Resolving the problem To fix this error you need to increase the block size to accommodate the record size: 1. Log into Designer and open the job. You can set this up to MB but you really shouldn't need to go over 1MB.
Using 4 MB could cause the job to use more memory than needed since all the links would use a 4 MB transport block size. While connecting Remote Desktop, Terminal server has been exceeded maximum number of allowed connections.
Error occurred processing a conditional compilation directive near string. Following link has issue description:.
While connecting to Datastage client, there is no response, and while restarting websphere services, following errors occurred. Make sure you have mapped every single field required for the next stage.
Sometime even after mapping the fields this error can be occurred and one of the reason could be that the view adapter has not linked the input and output fields. Hence in this case the required field mapping should be dropped and recreated.
Just to give an insight on this, the view adapter is an operator which is responsible for mapping the input and output fields. So if the interface schema is not having the same columns as operator input interface schema then this error will be reported. This is known issue and you can safely demote that warning into informational by adding this warning to Project specific message handler.
I picked the busiest times of day to execute a command that returned a list of connected users. Find a person with UNIX scripting knowledge, and you can build a nice process that reports the number of concurrent users.
The biggest challenge would be eliminating the duplicate entries in the command output, as a single user could have several open connections. Another challenge: concurrent licenses are only counted against Designer not Director , so you would need to eliminate any users that would only use Director and not Designer like Operations, the ESP username, etc.
