Message format

The message identification has the form: pfxnnnns, where:

pfx
The z/Server component prefix (facility ID)

The following facility IDs exist:

ID z/Server component
API Application programming interface (TCPIP)
BND IEWBND (Binder) interface
CSI Catalog search interface
DSC Holder task configuration
DYN Dynamic allocation
EMC Extended MCS interface
HLD Holder task interface
IPC Command task
JES Job entry subsystem interface
LIC License interface
MAL Email interface
REC Recovery exception handler
REX REXX command environment
SJB Started job interface
SLR TSO scheduler interface
SPR Standard pool routine
SRV Server interface
SSI Interface to z/OS SSI
STA Started task interface
TAU Eclipse client interface
UNI Unicode conversion services
USS UNIX Interface
XML XML system parser interface
ZCA CEA TSO/E address space services
nnnn
The message number for the component, for example, 0051. The message numbers are unique within a component.
s
The message severity:
I
Information
W
Warning
E
Error
S
Severe error

Informational messages are normally used for tracing or debugging purposes. Errors apply to the associated service and are typically caused by incorrect arguments. Severe errors may require z/Server to be restarted.

The message description provides information to identify the cause of the problem. Many messages contain placeholders ([mmm], where mmm is a consecutive number; for example, [002] is the second placeholder). These placeholders are replaced with specific values in the actual message.

The message description may contain messages, return and reason codes, etc. passed from invoked services (for example, the XML system parser or the security product). In these cases, the IBM manual to be consulted for details of the problem is given.

With very few exceptions, the first placeholder ([001]) of each message is the timestamp when the message was issued (hh:mm:ss.ttt):

hh
hour
mm
minutes
ss
seconds
ttt
milliseconds

The explanation for any message states whether the message is issued only at a certain IPTRACE level. The message will be issued at that trace level and higher. Trace levels include all messages from lower trace levels.
