Time saving tips for configuring WebSphere Application Server OEM Edition for z/OS

Kelly Hasler 1200009UMF | | Comment (1) | Visits (6768)

Tweet
  Working in WebSphere Application Server z/OS level 2, we sometimes see issues with the configuration of IBM WebSphere Application Server (WAS) OEM Edition for z/OS. Most are seen during the configuration stage to create a server instance of WAS OEM. To help save yourself some time during this process, here are a few things to check before you start this process.   SCLBDLL2 is a commonly missed library that needs to be in the system link list and APF authorized. Here is the complete list of libraries that need to be the system link... [More]

Using Fault Analyzer to view CICS Auxiliary Trace Datasets

GTodaro 0600002JYM | | Visits (8638)

Tweet
  It used to be that formatting a CICS Auxiliary Trace dataset meant submitting batch jobs to run the trace formatting utility DFHTUxxx. MANY batch jobs.   First a run to get the abbreviated trace, so you could see what the time range the trace dataset covered, and perhaps get some task numbers. Then another run, limiting the time range or task numbers formatted to ones you were interested in. Then yet another job to format only selected trace entries.   I was pleasantly surprised when I recently discovered that the IBM Fault... [More]

Are my CICS products compatible with z/OS Version 2 Release 1?

BillBulfin 1000004JHC | | Visits (13521)

Tweet
  Are you preparing for your next z/OS upgrade? Do you need to confirm if your CICS Transaction Server (CICS TS) or one or more of your CICS Tools is compatible or needs any additional maintenance? Does your site's IT governance policy require you to contact your software providers to confirm there are no compatibility issues for the z/OS upgrade? These questions are typical in most shops, and very often when working with IBM, you may use the IBM Support Portal to open an SR (Service Request) to ask what if any compatibility or... [More]

CHLAUTH - Allow some privileged admins

Morag Hughson 110000EQPN | | Comments (2) | Visits (25415)

Tweet
  WebSphere MQ V7.1 introduced a channel security feature called Channel Authentication Records, or CHLAUTH for short. The feature allows you to set rules to indicate what should happen to inbound connections to your queue manager. By default there are three rules in place and one of them is there to block all remote privileged users - that is those in the mqm group for example. To understand whether you are being blocked by this particular rule see " I'm being blocked by CHLAUTH - how can I work out why? "   AMQ8878:... [More]

A non-privileged MQ administrator

Morag Hughson 110000EQPN | | Comments (7) | Visits (19277)

Tweet
  With the new feature in WebSphere MQ V7.1 called Channel Authentication Records (or CHLAUTH for short) there is a lot of talk about privileged users and administrator access. In this post I want to discuss how to create a non-privileged MQ administrator. Before I begin let me define what I mean by each of those terms.   Privileged user A privileged user is a user that has authorization to do an operation without being explicitly granted access to do that operation. The users in the mqm group are examples of these privileged users,... [More]

Ten Quick Tips for Healthy MQ Cluster

ValerieLampkin 27000182R2 | | Comments (2) | Visits (19233)

Tweet
Clustering is a WebSphere MQ feature that is often confusing for many users.  I’d like to provide some guidelines you can follow to ensure the optimum health for your cluster. Here’s a list of Ten Tips for MQ Clustering: Don’t issue refresh command unless absolutely necessary. The REFRESH CLUSTER command can cause temporary disruption to traffic as it clears out the local cache. It is not a command that should be issued on a routine basis. Have 2 Full Repositories (no more, no less). When updates are made within a cluster, two messages are sent... [More]

Define a dead-letter queue (DLQ) for each queue manager

RichardHamilton 060001RC0R | | Comments (2) | Visits (41252)

Every queue manager should have a dead-letter queue (DLQ). What happens when a message cannot be delivered to the destination queue? Local puts If the message is put to a local queue and the message can't be delivered, then the MQPUT fails.  A reason code is returned to the putting application and the application will need to handle, or manual intervention might be required. Remote puts If a receiving channel cannot put the message to its destination queue, then it is placed on the dead letter queue, if one has been defined. If no dead letter... [More]

  Due to the recent security vulnerabilities (for example, POODLE Attack), the latest MQ product Fix Packs come with stricter, default security requirements that affect the use of the compromised Secure Socket Layer (SSL) and Weak Transport Level Security (TLS) Cipher Specifications. Since these Cipher Specification deprecations are disabled in MQ Fix Packs by default, below are the changes separated by MQ versions and Fix Pack levels.   I.

Balancing on Floating Garbage

  With more and more folks thinking about using the balanced garbage collection algorithm on their WebSphere application servers (-Xgcpolicy:balanced ) I thought I would write up a few things we have found out about using it.

What to do when threads are hung in socketRead() waiting for a response from a backend

David_Tiler 2700005EWB | | Visits (22031)

  A common cause of hung threads in WebSphere Application Server is when a thread sends a request to a backend server, such as a database, and waits an unexpectedly long time for a response.  When this occurs, you will see socketRead() at the top of the thread's stack trace.  For example:   [9/8/15 19:19:27:702 EDT] 00000062 ThreadMonitor W   WSVR0605W: Thread "WebContainer : 2301" (00001785) has been active for 1425013 milliseconds and may be hung.  There is/are 21 thread(s) in total in the...

Response files to be used with Installation Manager for WebSphere Application Server offerings

Vishav_Shergill 120000GKJX | | Comments (2) | Visits (8066)

  If Graphical capabilities are not available on the system, then the response file in silent mode can be used to install/uninstall/rollback. Installation Manager (IM)  itself can be installed in silent mode, and then subsequent operations (such as installing or uninstalling) can also be performed in silent mode. Silent mode uses XML-formatted response files as input and can perform multiple operations in a single operation. Here is a sample command to run response file: imcl -acceptLicense input <RESPONSEFILE>.xml -log... [More]

IBM Installation Manager Fun - Driving IM in different ways

DaveHay 100000GC6F | | Visits (6807)

Tweet
  Many of us are familiar with the traditional IBM Installation Manager (IIM) Eclipse-based rich client, IBMIM , that allows one to drive IIM in an environment where a GUI is available. However, this approach is not always feasible, especially in an environment where one needs to access IIM on a remote server, perhaps one without a GUI console i.e. operating in so-called "headless" mode. This is often the case with remote UNIX® servers ( AIX, Linux, Solaris etc. ) where one's only point of access is via a remote terminal... [More]

Working around native out of memory in the low memory region with -Xmcrs

MicheleCalcavecchia 270000HCF1 | | Comments (2) | Visits (8183)

Tweet
  If there is still free memory in the system when a native out-of-memory error occurs, then the problem is likely to be a shortage of memory in the low-memory region (under 4GB). Although the Java heap can be located above this boundary, other data, which are associated with Java objects, are located in the lower memory segments. Specifically these are the memory segments associated with threads, classes and monitors.  See the following related content: Using -Xgc:preferredHeapBase with -Xcompressedrefs  ... [More]

    Shared resource Directory The shared resources directory is the directory where installation artifacts are located, which can be used by one or more package groups.  The Shared Resources Directory acts as a cache of data to local and web repositories.

WebSphere MQ V7.1 introduced a feature which allows you to block IP addresses from connecting to your queue manager - this feature is Channel Authentication Records, or CHLAUTH for short. In fact there are two ways that CHLAUTH allows you to block IP addresses. Today we will describe when to use each type. Two ways to block First let us show you two examples of how to block IP addresses using CHLAUTH.
