Infosphere Information Server (IIS) – Where you can view DataStage and QualityStage Logs?

During the course of the week, the discussion happened regarding the different places where a person might read the DataStage and QualityStage logs in InfoSphere. I hadn’t really thought about it, but here are a few places that come to mind:

  • IBM InfoSphere DataStage and QualityStage Operations Console
  • IBM InfoSphere DataStage and QualityStage Director client
  • IBM InfoSphere DataStage and QualityStage Designer client by pressing Ctrl+L

Essbase Connector Error – Client Commands are Currently Not Being Accepted

DataStage Essbase Connector, Essbase Connector Error, Client Commands are Currently Not Being Accepted
DataStage Essbase Connector

While investigating a recent Infosphere Information Server (IIS), Datastage, Essbase Connect error I found the explanations of the probable causes of the error not to be terribly meaningful.  So, now that I have run our error to ground, I thought it might be nice to jot down a quick note of the potential cause of the ‘Client Commands are Currently Not Being Accepted’ error, which I gleaned from the process.

Error Message Id

  • IIS-CONN-ESSBASE-01010

Error Message

An error occurred while processing the request on the server. The error information is 1051544 (message on contacting or from application:[<<DateTimeStamp>>]Local////3544/Error(1013204) Client Commands are Currently Not Being Accepted.

Possible Causes of The Error

This Error is a problem with access to the Essbase object or accessing the security within the Essbase Object.  This can be a result of multiple issues, such as:

  • Object doesn’t exist – The Essbase object didn’t exist in the location specified,
  • Communications – the location is unavailable or cannot be reached,
  • Path Security – Security gets in the way to access the Essbase object location
  • Essbase Security – Security within the Essbase object does not support the user or filter being submitted. Also, the Essbase object security may be corrupted or incomplete.
  • Essbase Object Structure –  the Essbase object was not properly structured to support the filter or the Essbase filter is malformed for the current structure.

What Are The DataStage / QualityStage Join Stages?

Three Stages Which Join Records
Three Stages Which Join Records

While chasing an error to which only applied to join type stages, I thought it might be nice to identify what the InfoSphere Information Server DataStage / QualityStage are.  There are three of them, as you can see from the picture above, which are the:

  • Join Stage,
  • Lookup Stage,
  • And, Merge Stage.

All three stages that join data based on the values of identified key columns.

Parallel jobs on Windows fail with APT_IOPort::readBlkVirt;error

APT_IOPort::readBlkVirt Error Screenshot
APT_IOPort::readBlkVirt Error Screenshot

This a known error for windows systems and applies to DataStage and DataQuality jobs using the any or all the three join type stages (Join, Merge, and Lookup).

Error Message

  • <<Link name>>,0: APT_IOPort::readBlkVirt: read for block header, partition 0, [fd 4], returned -1 with errno 10,054 (Unknown error)

Message ID

  • IIS-DSEE-TFIO-00223

Applies To

  • Windows systems only
  • Parallel Engine Jobs the three join type stages (Join, Merge, and Lookup). It does not apply to Server Engine jobs.
  • Infosphere Information Server (IIS), Datastage and DataQuality 9.1 and higher

The Fix

  • Add the APT_NO_IOCOMM_OPTIMIZATION in project administrator and set to blank or 0. I left it blank so it would not impact other jobs
  • Add the environment variable to the job producing the error and set to 1

What it APT_NO_IOCOMM_OPTIMIZATION Does

  • Sets the use of shared memory as the transport type, rather than using the default sockets transport type.
  • Note that in most cases sockets transport type is faster, so, you likely will not to set this across the project as the default for all job. It is best to apply it as necessary for problematic jobs.

DataStage – How to Pass the Invocation ID from one Sequence to another

DataStage Invocation ID Passing Pattern Overview
DataStage Invocation ID Passing Pattern Overview

When you are controlling a chain of sequences in the job stream and taking advantage of reusable (multiple instances) jobs it is useful to be able to pass the Invocation ID from the master controlling sequence and have it passed down and assigned to the job run.  This can easily be done with needing to manual enter the values in each of the sequences, by leveraging the DSJobInvocationId variable.  For this to work:

  • The job must have ‘Allow Multiple Instance’ enabled
  • The Invocation Id must be provided in the Parent sequence must have the Invocation Name entered
  • The receiving child sequence will have the invocation variable entered
  • At runtime, a DataStage invocation id instance of the multi-instance job will generate with its own logs.

Variable Name

  • DSJobInvocationId

Note

This approach allows for the reuse of job and the assignment of meaningful instance extension names, which are managed for a single point of entry in the object tree.

How to know if your Oracle Client install is 32 Bit or 64 Bit

How to know if your Oracle Client install is 32 Bit or 64 Bit

Sometimes you just need to know if your Oracle Client install is 32 bit or 64 bit. But how do you figure that out? Here are two methods you can try.

The first method

Go to the %ORACLE_HOME%\inventory\ContentsXML folder and open the comps.xml file.
Look for <DEP_LIST> on the ~second screen.

If you see this: PLAT=”NT_AMD64” then your Oracle Home is 64 bit
If you see this: PLAT=”NT_X86” then your Oracle Home is 32 bit.

It is possible to have both the 32-bit and the 64-bit Oracle Homes installed.

The second method

This method is a bit faster. Windows has a different lib directory for 32-bit and 64-bit software. If you look under the ORACLE_HOME folder if you see a “lib” AND a “lib32” folder you have a 64 bit Oracle Client. If you see just the “lib” folder you’ve got a 32 bit Oracle Client.

Oracle – How to get a list of user permission grants

IBM Infosphere Information Server (IIS), Oracle – How to get a list of user permission grants
IBM Infosphere Information Server (IIS)

Since the Infosphere, information server, repository, has to be installed manually with the scripts provided in the IBM software, sometimes you run into difficulties. So, here’s a quick script, which I have found useful in the past to identify user permissions for the IAUSER on Oracle database’s to help rundown discrepancies in user permissions.

 

SELECT *

FROM ALL_TAB_PRIVS

WHERE  GRANTEE = ‘iauser’

 

If we cannot run against the ALL_TAB_PRIVS view, then we can try the ALL_TAB_PRIVS view:

 

SELECT *

FROM USER_TAB_PRIVS

WHERE  GRANTEE = ‘iauser’
