Log files
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:
- userlog/$LOGNAME/
User-specific log files are located in
userlog/$LOGNAME/
, whereuserlog
is the combined value of theuser.log
andDSTORE_LOG_DIRECTORY
directives inrse.env
, and$LOGNAME
is the logon user ID (uppercase). If theuser.log
directive 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 invokedffs.log
- The log of the Foreign File System (FFS) server, that executes native MVS functionsffsget.log
- The log of the file reader, that reads a sequential data set or a PDS memberffsput.log
- The log of the file writer, that writes a sequential data set or a PDS memberffslock.log
- The log of the lock manager, that locks/unlocks a sequential data set or a PDS memberrsecomm.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)
Note:- The
.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”.
- daemon-home/server/
The RSE daemon and RSE thread pool specific log files are located in
daemon-home/server
, wheredaemon-home
is the value of thedaemon.log
directive inrse.env
.rsedaemon.log
- The log of the RSE daemonrseserver.log
- The log of the RSE thread poolsaudit.log
- The RSE audit trailserverlogs.count
- Counter for logging RSE thread pool streamsstderr.*.log
- RSE thread pool standard error streamstdout.*.log
- RSE thread pool standard output stream
- /tmp
IVP-specific log files (Installation Verification Program) are located in the directory referenced by
TMPDIR
, if this variable is defined inrse.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 thefekfivpi
