9 IBM VM messages CDRT messages The Java virtual machine (VM) that is used by the IBM Software Developers Kit (SDK) is the IBM J9 virtual machine. Messages are issued by the IBM VM in response to certain conditions. These IBM messages, error codes, and exit codes apply to multiple versions of the JVM. There are three main types of message: Information Information messages provide information about JVM For example, a dump information message is typically issued when a dump agent requests a Java dump. Warning Warning messages are issued by the JVM to indicate conditions that might need user intervention. Error Error messages are issued by the JVM when normal processing cannot proceed, because of unexpected conditions. IBM VM messages have the following format: JVMTYPENUM&, where: v JVM is a standard prefix. v TYPE refers to the JVM subcomponent that issued the message. v NUM is a numerical number. v & is one of the following codes: I Information message W Warning message E Error message IBM VM messages can help you with problem determination. Refer to diagnostic information for more detailed information about diagnosing problems with the IBM JVM. Codert module messages.

10 JVMDUMP000E JVMDUMP012E DUMP messages Dump agent messages. JVMDUMP000E Dump option unrecognized: -Xdump:%s An option used with the -Xdump parameter is unknown. Use -Xdump:help to find the correct syntax for the -Xdump options. JVMDUMP001E Dump event unrecognized:...%s The event name provided with the -Xdump parameter is unknown. Use -Xdump:events to find the supported set of event names. JVMDUMP002W Token unrecognized: %%%1$c An unidentified token was found in the dump label. Use -Xdump:tokens to find the supported set of tokens. JVMDUMP003E Dump agent unrecognized: %s An unsupported dump type has been requested. Use -Xdump:help to find the supported set of dump types. JVMDUMP004E Missing file name The dump file name could not be found. The dump cannot be written. Provide a valid filename for the dump. JVMDUMP005E Missing external tool The executable file for the tool could not be found. The tool cannot run. Provide a valid path and filename for the executable file. JVMDUMP006I Processing dump event \"%1$s\", detail \"%3$.*2$s\" - please wait. handled. A dump event has occurred and is being The JVM attempts to process the event. No response is required. JVMDUMP007I JVM Requesting %1$s dump using '%2$s' The JVM is about to write a dump. The dump might have been triggered by an event, such as an exception, or requested using JVMTI, JVMRI, -Xtrace:trigger or the com.ibm.jvm.dump Java API. The JVM attempts to write the dump. A second message is generated when the dump is complete. Review the dump and take appropriate action. JVMDUMP009I %s dump not available The specified dump type is not currently available. For example, a JVM trace snap dump has been requested, but JVM trace is not enabled. The JVM does not write the dump. This message is only for information. JVMDUMP010I %1$s dump written to %2$s location. The dump was written to the specified To understand how to interpret a Java dump file, refer to diagnostic information. JVMDUMP011I %1$s dump created process %2$d A tool dump process has been created. The JVM runs the executable process specified for the tool dump. Any parameters are passed to the process. Refer to the documentation for the tool creating the dump process. JVMDUMP012E Error in %1$s dump:%2$s The JVM detected an error while 2 IBM SDK, Java Technology Edition: IBM VM messages

11 JVMDUMP013I JVMDUMP024W attempting to produce a dump. The JVM continues, but the dump might not be usable. Refer to diagnostic information or contact your local IBM service JVMDUMP013I Processed dump event \"%1$s\", detail "%3$.*2$s". handled. A dump event occurred and has been Refer to other messages issued by the JVM for the location of the dump file, or for other actions required. JVMDUMP014E VM Action unrecognized:...%s A specified dump request action was not understood by the JVM. and ends. The JVM produces help information Use -Xdump:request to check that your request is valid. JVMDUMP015I Aborting: Cannot open or read (%s) read mode. JVMDUMP016I The JVM cannot open a dump file in INTERNAL USE ONLY INTERNAL USE ONLY Aborting: Cannot create file (%s) An attempt by the JVM to open a new file has failed. INTERNAL USE ONLY INTERNAL USE ONLY JVMDUMP017I Aborting: Cannot compress file (%s) The JVM cannot compress a file. INTERNAL USE ONLY INTERNAL USE ONLY JVMDUMP018W Requested event is not available: run with -Xdump:dynamic flag A dump has been requested on an event type that is not supported. INTERNAL USE ONLY INTERNAL USE ONLY JVMDUMP019I JVM requesting %s dump A dump file of the type specified has been requested. The JVM attempts to produce a dump of the specified type. Wait for a message indicating that the dump is complete. JVMDUMP020I %s dump has been written A dump file of the type specified has been written. To understand how to interpret the dump file, refer to Java diagnostic information. JVMDUMP022W The requested heap compaction has not been performed because exclusive access was not requested or could not be obtained. The garbage collector could not run because the gc thread did not have exclusive access to the heap. The dump file is not produced. Modify the -Xdump option to request exclusive access. See the Java diagnostic information for valid dump request types. JVMDUMP023W The requested heap preparation has not been performed because exclusive access was not requested or could not be obtained. The dump thread must lock the heap to prevent changes while the dump is taken. Either no attempt was made to obtain the lock or the lock could not be obtained. The JVM does not produce the specified dump. Modify the -Xdump option to request exclusive access. See the Java diagnostic information for valid dump request types. JVMDUMP024W Multiple heapdumps were requested but %%id is missing from file label:. Dumps will overwrite The JVM replaces the %%id insertion point with a unique number. Because %%id is missing the replacement cannot take place, causing a potential file name clash and file overwrite. The JVM informs the user and produces dumps as requested. IBM VM messages 3

12 JVMDMP025I JVMDUMP032I If you do not want files overwritten, specify a file label that includes the %%id. JVMDMP025I IEATDUMP failure for DSN='%s' RC=0x%08X RSN=0x%08X An IEATDUMP was requested but could not be produced. The JVM will output the message on the operator console. Check the response code provided in the error using the Diagnostics Guide or the z/os V1R7.0 MVS Authorized Assembler Services Reference, Return and Reason Codes. JVMDUMP026 IEATDUMP Name exceeding maximum allowed length. Default name used. The file label exceeded the maximum length for file names on z/os. The dump file is not produced. Refer to Java diagnostic information for information about producing dumps on z/os. JVMDUMP027W The requested heapdump has not been produced because another component is holding the VM exclusive lock. The exclusive VM lock must be held to produce a usable heapdump. Although the VM exclusive lock was requested by the user, the VM could not obtain the lock in a reasonable time. This behavior avoids risking a deadlock. heapdump. The VM does not produce a Wait for 1 minute and try taking the heapdump again when the VM exclusive lock might be free. JVMDUMP028W The VM exclusive lock could not be acquired before taking the system dump. Although the VM exclusive lock was requested by the user, the VM could not obtain the lock in a reasonable time before taking the system dump. This behavior avoids risking a deadlock. The VM produces a system dump without taking the VM exclusive lock. The dump might show an inconsistent view of the VM data structures and heap. Wait for 1 minute and try taking the system dump again when the VM exclusive lock might be free. JVMDUMP029W The request for prepwalk or compact before taking a system dump will be ignored because the VM exclusive lock was not requested. The user requested the prepwalk or compact options before taking a system dump, but did not request the VM exclusive lock. These actions require the exclusive VM lock. The system dump is taken without running prepwalk or compact. Modify the -Xdump:system parameter to include the exclusive request option. For example: -Xdump:system:events=user,request=exclusive+ compact+prepwalk JVMDUMP030W Cannot write dump to file %s: %s The JVM was unable to write a dump to the specified file. There might be multiple causes, including insufficient file system permissions or specifying a file path that does not exist. The JVM uses a default file name. The name and location of the file are indicated by the messages produced when the dump is written. Correct the problem with the specified file path or change the target dump file with the file= option. JVMDUMP031W The requested heapdump has not been produced because the VM exclusive lock was not requested. Add request=exclusive+prepwalk+compact to your -Xdump:heap: command line option. A heapdump dump agent was configured using the -Xdump option or JVMTI without requesting that the exclusive VM lock. The JVM does not take the heapdump because the dump might be corrupted without the VM exclusive lock in place. Change the -Xdump:heap: option to include the request=exclusive option. For example: -Xdump:heap:events=user,request=exclusive JVMDUMP032I JVM requested %1$s dump using '%2$s' in response to an event The JVM writes a dump because an event, such as an exception, was triggered. The JVM attempts to write the dump. A second message is produced when the dump is complete. Review the dump and take appropriate action. 4 IBM SDK, Java Technology Edition: IBM VM messages

13 JVMDUMP033I JVMDUMP042W JVMDUMP033I JVM requested %1$s dump in response to an event The JVM writes a dump because an event, such as an exception, has been triggered. The JVM attempts to write the dump. A second message is produced when the dump is complete. Review the dump and take appropriate action. JVMDUMP034I User requested %1$s dump using '%2$s' through %3$s The JVM writes a dump in response to a request through an API, such as JVMTI, or through the -Xtrace:trigger option. The JVM attempts to write the dump. A second message is produced when the dump is complete. Review the dump and take appropriate action. JVMDUMP035I User requested %1$s dump through %2$s The JVM writes a dump in response to a user request through an API, such as JVMTI, or through the -Xtrace:trigger option. The JVM attempts to write the dump. A second message is produced when the dump is complete. Review the dump and take appropriate action. JVMDUMP036I Invalid or missing -Xdump filter valid filter. A valid -Xdump filter must be supplied. The dump agent is not loaded. Modify the dump option to include a JVMDUMP037E Error in %1$s dump: %2$s failed, error code: %3$d An error has occurred in a JVM dump agent. An operating system call used by the agent has failed. Check preceding JVM messages. The JVMDUMP007I message includes the command string supplied for tool dumps. Check that the command string is correct. JVMDUMP038E Snap dump is not written because tracing to file: %1$s Snap dumps are not produced when a trace output file is in use. message. Use the trace file specified in the JVMDUMP039I Processing dump event \"%1$s\", detail \"%3$.*2$s\" at %4$s - please wait. A dump event is being handled. The JVM generates dumps as configured for the event by the -Xdump option. No action is required. JVMDUMP040I %1$s dump written to dataset(s) using name template %2$s The dump is written using the specified data set name template. Locate the dump data set, or data sets, and take appropriate action. JVMDUMP041I Incorrect use of -Xdump msg_filter The suboption msg_filter is applicable only to events throw, systhrow, catch, and uncaught. The dump agent is not loaded. Modify the dump option to apply the msg_filter suboption to applicable events. JVMDUMP042W Abort signal received while running on Java stack. The JVM dump agents could not be run. The JVM abort signal handler was called on a thread that is running on a Java stack. The JVM dump agents are not run to avoid further problems. The abort signal is passed on to the operating system. No specific action is required. Look for other messages that are produced to assist you with problem determination. Refer to operating system documentation for information about obtaining dumps on abort signals. IBM VM messages 5
