How to diagnose ObjectServer performance log files using UNIX filtering functions and spreadsheets
The ObjectServer writes performance information to log files. These logs can give information the time spent running SQL queries, identify which clients are using excessive resources and show CPU usage of individual triggers. In my experience it's often useful to get a high level picture before diving into details. One way of encouraging yourself to look at the overview before delving into details is to generate a graph of key performance indicators over time and focus on areas of interest highlighted by the graph. In this blog I will describe... [More]

How to Identify Which .NET Framework Probe is Using
1) Use Process Explorer from Sysinternals to open current running process. Download link: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx 2) Double-click on the probe name (Example: nco_p_wineventlog). 3) Check the .NET version from .NET Assemblies tab. Note: - The first three versions of the CLR are specified by "v1.0.3705", "v1.1.4322", and "v2.0.50727". - The .NET Framework version 3.0 and 3.5 use version 2.0.50727 of the CLR. - Beginning with the .NET Framework version 4, only the major and...

How to Determine Which Version of Microsoft .NET Framework Installed
Tivoli Netcool OMNIbus Probes with dependency on Microsoft .Net Framework may have a minimum level of .Net version to run. To check what version of .Net installed on the machine, follow steps below: 1) Run command "regedit" from console to open Registry Editor 2) Look for HKEY_LOCAL_MACHINE\Microsoft\NET Framework Setup\NDP 3) All installed .NET Framework versions are listed under NDP drop-down list Example: Screenshot from my workstation (I have .Net v3.5 SP1 installed): Reference for each Microsoft .Net version numbers: ...

32-bit processes & Java heap size
For an OMNIbus Web GUI server that services requests for lots of users there may be a need to increase the Java heap size that is allocated for the server. However, it should be noted that for 32-bit processes there is an upper limit for the amount of memory that can be used: 4GB. This cannot be changed and is in force even if your server has a 64-bit processor, 64-bit Operating System and more than 4GB memory. This limit has some knock-on effects to the amount of heap that can practically be allocated. The memory used by the Web GUI server... [More]

A little known or used probe or gateway command line option -dumpprops
When working with various OMNIbus
integrations it is quite often that they are run with the “-version”
argument to obtain the version information. However there is another
universal integration argument that is not very well known called
“dumpprops”. The output of this argument provides a
full list of all the specific integration arguments and values, along
with any of the generic integration arguments and values that are
provided by the version of OMNIbus used. The values shown in the
output are those that would be used when the... [More]

Core Dumps - Unix (OMNIbus Probes Troubleshooting)
Core dumps in UNIX are important to analyze the memory state of a specific probe during a crash. It is used as debugging aid to investigate the reason behind the crash (memory leak, segmentation faults, etc) and where does the crash occur in probe source codes. NOTE: Users need to request probe binary which built with Debug mode turned ON from OMNIbus Integrations L3 Support for a meaningful dump analysis. SMC Wiki link:... [More]

Using Valgrind Debugging Tool (OMNIbus Probes Troubleshooting)
Valgrind is a debugging tool that can be used by OMNIbus users to detect probes memory leak and error thrown by glibc. Due to limited platform support, this tool can only be used if probe runs on Linux machine. This tool is most useful if the issue on user environment is hardly reproduced on other environment (example: L2 Support env), because it run probe binary as normal execution. Users are also not required to produce core files to have the backtrace log. Therefore, users do not need to wait memory leak until probe crash to have the core... [More]

How to Force Probe to Use Specific .NET Version
Why need to enforce which .NET version to use? Some issues on Microsoft .NET Framework API are impacting probe which require forcing of using specific .NET version as a workaround. Examples: 1) Defect in .NET 3.5 causes probe to misbehave in East-Asian locale when event data volume reaches 2GB. Users of East-Asian languages must either enable UTF-8 mode in this probe or upgrade .NET Framework in probe machine to version 4.0. 2) The design of .NET Framework 4.0 to use strict rendering may cause probe fail to retrieve EventDescription if...

light that different user profiles may require different usage of SMC

to select options that they feel more applicable to them. I will be in
touch with the DeveloperWorks team to see if we can reduce the footprint
of the imagery further (we are using dynamic links into their icons). Textual SMC URL (2Kb) - smcsig1.html <hr><font size=1
