Abend files

When a process ends abnormally (an abend or dump), an entry is made in the syslog, or the Windows Event log. If there is more data to be written than is appropriate for the log, a new file is created to contain it, and the log entry tells you the file name. You need to send the file to your IBM Support Center for analysis.

Abend files are never generated during normal operation; always involve your IBM Support Center when they do occur.

The new file is called:
Windows
filename.abend in the broker_work_path\errors directory (if broker_work_path has been set using the -w parameter of the mqsicreatebroker command), or, if the broker work path has not been specified, to the install_dir\errors directory, where install_dir is the directory where WebSphere Message Broker is installed. If it is not possible to write to this directory, the file is put in the install_dir\log directory, but in either case, the message in the Event Log tells you where to find it.

Use the work path parameter, -w of the mqsicreatebroker command to create the errors directory in a hard drive partition that does not contain WebSphere Message Broker or Windows itself.

UNIX
filename.abend in the /var/wmqi/errors directory.
z/OS
filename.abend in the /component_HFS/log directory.
where filename is a unique dynamically-allocated name, as given in the syslog or Event Log message.

Periodically clear any unwanted abend files from the errors or z/OS log directory. In extreme conditions, you might find that your system performance degrades due to significant space being used up with old abend files.

WebSphere Message Broker for z/OS abends

Abend code
2C1
Explanation
The WebSphere Message Broker for z/OS infrastructure encountered a severe internal error. The reason code helps the IBM Support Center to identify the source of the error. It has the format X'ppmmnnnn', where pp defines the part within the infrastructure where the error occurred, mm defines the specific location of the error, and nnnn defines a recursion index.
You can resolve the following reason codes but you should refer other codes to the IBM Support Center.

ABN=S2C1-0001xxxx Error opening an HFS file
The HFS component might be full or the broker user ID might not
have the correct permissions to access files or directories in the HFS
component.

ABN=S2C1-0113xxxx Region size too small
Source

System Action
The system might issue a dump.

Search the problem-reporting databases for a fix for the problem. If no fix exists, contact the IBM Support Center, providing the reason code and, if present, the dump.
