z/OS® Explorer creates log files that can assist you and IBM® support center in identifying and solving problems. The following list is an overview of log files that can be created on your z/OS host system. Next to these product-specific logs, be sure to check the SYSLOG for any related messages.
MVS™ based logs can be located through the appropriate DD statement. z/OS UNIX based log files are located in the following directories:
User-specific log files are located in
userlogis the combined value of the
$LOGNAMEis the logon user ID (uppercase). If the
user.logdirective is a null string, the home path of the user is used. The home path is defined in the OMVS security segment of the user ID.
.dstoreMemLogging- DataStore memory usage logging
.dstoreTrace- DataStore action logging
.dstoreHashmap.*- snapshot of the active DataStore hashmap
.dstoreStackTrace.*- snapshot of the active DataStore threads and where they were invoked
ffs.log- The log of the Foreign File System (FFS) server, that executes native MVS functions
ffsget.log- The log of the file reader, that reads a sequential data set or a PDS member
ffsput.log- The log of the file writer, that writes a sequential data set or a PDS member
ffslock.log- The log of the lock manager, that locks/unlocks a sequential data set or a PDS member
rsecomm.log- The log of the RSE server, that handles commands from the client and the communication logging of all services relying on RSE (may contain Java™ exception stack trace)
.dstore*log files start with a dot (.), which makes them hidden. Use z/OS UNIX command ls –lA to list hidden files and directories. When using the z/OS Explorer client, select the Window > Preferences… > Remote Systems > Files preference page and enable “Show hidden files”.
The RSE daemon and RSE thread pool specific log files are located in
daemon-homeis the value of the
rsedaemon.log- The log of the RSE daemon
rseserver.log- The log of the RSE thread pools
audit.log- The RSE audit trail
serverlogs.count- Counter for logging RSE thread pool streams
stderr.*.log- RSE thread pool standard error stream
stdout.*.log- RSE thread pool standard output stream
IVP-specific log files (Installation Verification Program) are located in the directory referenced by
TMPDIR, if this variable is defined in
rse.env. If the variable is not defined, the files are created in
/tmp. The MODIFY LOGS operator command for the RSED started task also creates its output in this directory.
fekfivpi.log- The log of the
feklogs.*- Output of the MODIFY LOGS operator command
