DescriptionError TokenError Number
An attribute valid only for OSS server processes
was specified for a Guardian server process.
ZPWY-ERR-SPI-OSSATTRUSED4025
The value specified for an OSS attribute exceeds
the maximum length.
ZPWY-ERR-SPI-OSSATTRTOOBIG4026
An OSS pathname in the command is invalid.ZPWY-ERR-SPI-INVALIDPATHNAME4027
The combined length of the values defined for
ZPWY-TKN-DEF-SCARGLIST and
ZPWY-ERR-SPI-ARGENVEXCEEDMAX4028
ZPWY-TKN-DEF-SCENV exceeds the
24,000-character maximum.
A relative OSS pathname, when resolved using
the OSS directory specified for
ZPWY-ERR-SPI-RESOLVEDTOOBIG4029
ZPWY-TKN-DEF-SCCWD, results in an absolute
pathname that exceeds the maximum 1024 bytes
allowed.
The value specified for ZPWY-TKN-DEF-SCCWD
is not an absolute pathname.
ZPWY-ERR-SPI-NAMENOTABSOLUTE4030
For descriptions of all error-token values and their associated error lists, see “Event Management”
(page 163).
For considerations regarding errors that can occur when a server process is in debug mode, see
the TS/MP 2.5 Pathsend and Server Programming Manual.
Considerations
• The tokens and fields included in the command buffer must be valid for the process type
defined for the server class.
• The name assigned in the ZNAME field in ZPWY-DDL-SEL-SC must be unique in the Pathway
subsystem.
• If no value is specified for ZPWY-TKN-DEF-SCCWD for OSS server processes, then the values
specified for these tokens must be absolute OSS pathnames:
ZPWY-TKN-DEF-SCPROGRAMOSS
ZPWY-TKN-DEF-SCSTDERR
ZPWY-TKN-DEF-SCSTDIN
ZPWY-TKN-DEF-SCSTDOUT
• A link to a server class is an access path to a server process in the class. The link is used to
send a request to and receive a reply from a server process. A link can only be used for one
send operation at a time.
• ACS subsystem processes share a link among the multiple Pathsend processes executing in
the CPU of the ACS subsystem processes. Only one Pathsend process at a time can use the
link by calling the SERVERCLASS_SEND procedure.
• The ZLINKDEPTH field in ZPWY-DDL-DEF-SC specifies the maximum number of concurrent links
that any one link manager (such as ACS subsystem processor a Pathway/iTS TCP) can have
to the same server in a server class. A link manager, however, can also have links to other
servers in the class.
For example, if ZLINKDEPTH is 1, a ACS subsystem process can only have one link to each
server process. Each request to the PATHMON process for an additional link which results in
a link to a different server process.
• Each link from a link manager results in a single open of the server. The ACS subsystem
processes make the open available for use by multiple Pathsend requesters.
If you are using the Pathway/iTS product, then note that the TCP makes the open available
for use by multiple SCREEN COBOL programs.
