DISPLAY_JOURNAL table function

Edit online

The DISPLAY_JOURNAL table function returns information about journal entries. It returns information similar to what is returned by the Display Journal (DSPJRN) CL command and the Retrieve Journal Entries (QjoRetrieveJournalEntries) API.

Authorization:

The caller must have *USE authority to the journal and to all requested journal receivers.
*OBJEXIST authority is required to the journal if object-name is omitted or if object-name specifies an object that no longer exists.
If object-name is *ALL, the caller must be authorized to every object associated with a journal entry.
- For objects in the QSYS file system, the caller must have:
  - *USE authority to the object, and
  - *EXECUTE to the library containing the object.
- For objects in the integrated file system, the caller must have:
  - *R for the object
  - *X for every directory in the object's path.

The schema is QSYS2.

journal-library

A character or graphic string expression that identifies the name of the library containing the journal. The name cannot be *LIBL or *CURLIB.

journal-name

A character or graphic string expression that identifies the name of the journal.

receiver-library

A character or graphic string expression that identifies the name of the starting journal receiver library. The name can be *LIBL or *CURLIB.

receiver-name

A character or graphic string expression that identifies the name of the starting journal receiver. If one of the special values is specified, the receiver-library value will be ignored. Otherwise, the receiver-name and receiver-library must identify a valid journal receiver.

If no journal receiver is specified, *CURRENT is used.

*CURRENT: The journal receiver that is currently attached when starting to convert journal entries is used.
*CURCHAIN: The journal receiver chain that includes the journal receiver that is currently attached when starting to convert journal entries is used. This receiver chain does not cross a break in the chain. If there is a break in the chain, the receiver range is from the most recent break in the chain through the receiver that is attached when starting to convert journal entries.
*CURAVLCHN: The journal receiver chain that includes the journal receiver that is attached when starting to convert journal entries is used. This receiver chain does not cross a break in the chain. If there is a break in the chain, the receiver range is from the most recent break in the chain through the receiver that is attached when starting to convert journal entries. If journal receivers exist in the receiver chain that are not available because they were saved with the storage freed option, those journal receivers will be ignored and entries will be converted starting with the first available journal receiver in the chain.
*CURSEQCHN: The journal receiver chain that includes the journal receiver that is attached when starting to convert journal entries is used, starting with the most recent journal receiver in which the journal sequence number was reset if the journal sequence number was reset in the receiver chain. This receiver chain does not cross a break in the chain. If there is a break in the chain, the receiver range is from the most recent break in the chain through the receiver that is attached when starting to convert journal entries. If journal receivers exist in the receiver chain that are not available because they were saved with the storage freed option, those journal receivers will be ignored and entries will be converted starting with the first available journal receiver in the chain.

starting-timestamp

A timestamp value that specifies the starting timestamp to use^¹.

A value cannot be specified for both starting-timestamp and starting-sequence.

If no starting timestamp is specified, the earliest timestamp in the receiver range is used.

starting-sequence

A decimal expression that identifies the starting sequence number to use. If the starting-sequence value is not found in the receiver range, an error is returned.

A value cannot be specified for both starting-timestamp and starting-sequence.

If no starting sequence is specified, the first sequence number in the receiver range is used.

journal-codes

A character or graphic string expression that lists the journal codes to return. The string can contain the special values of *ALL or *CTL, or it can be a list of one or more journal codes. Journal codes in the string can be separated by one or more separators. Separators are blank and comma. For example, a valid string can be 'RJ' or 'R J' or 'R,J' or 'R, J'.

If no string is provided, *ALL is used.

journal-types

A character or graphic string expression that lists the journal entry types to return. The string can contain the special values of *ALL or *RCD, or it can be a list of one or more journal entry types. Journal entry types in the string can be separated by one or more separators. Separators are blank and comma. For example, a valid string can be 'JFCT' or 'JF CT' or 'JF,CT' or 'JF, CT'.

If no string is provided, *ALL is used.

object-library

A character or graphic string expression that identifies the name of an object library. The values *LIBL and *CURLIB are allowed.

object-name

A character or graphic string expression that contains up to 300 object names. Multiple names can be separated by one or more separators. Separators are blank and comma.

If object-name is the special value of *ALL, object-library must contain a library name and object-type must contain a valid object type. Otherwise, each object name must identify a valid object using the same object-library, object-type, and object-member parameters.

If no object name is provided, a value of *ALLFILE is used for the journaled file name on the API interface.

object-type

A character or graphic string expression that identifies the system object type for the object. The value must be *DTAARA, *DTAQ, *FILE, or *LIB.

object-member

A character or graphic string expression that identifies the name of a member. It can be a special value of *FIRST, *ALL, or *NONE or a valid member name. If the object type is not *FILE, the member name is ignored.

user

A character or graphic string expression that identifies the user profile name for the current user of the job. If user is not specified, *ALL is used.

job

A character or graphic string expression that identifies the name of a job. Two forms of a job name are supported.

A fully qualified job name in the form job-number/job-user/job-name.
The first 10 characters are the job name, the second 10 characters are the user name, and the last 6 characters are the job number.

If job is not specified, *ALL is used.

program

A character or graphic string expression that identifies the name of a program. If program is not specified, *ALL is used.

ending-receiver-library

A character or graphic string expression that identifies the name of the ending journal receiver library. The name can be *LIBL or *CURLIB. If ending-receiver-name is not *CURRENT, a value for ending-receiver-library must be specified.

The value of this parameter is ignored if eof-delay is greater than zero.

ending-receiver-name

A character or graphic string expression that identifies the name of the ending journal receiver. If the special value *CURRENT is specified, the ending-receiver-library value will be ignored. Otherwise, the ending-receiver-name and ending-receiver-library must identify a valid journal receiver.

If ending-receiver-name is not specified, *CURRENT is used.

The value of this parameter is ignored if eof-delay is greater than zero.

ending-timestamp

A timestamp value that specifies the ending timestamp to use^¹.

A value cannot be specified for both ending-timestamp and ending-sequence. This parameter cannot be specified if eof-delay is greater than zero.

If no ending timestamp is specified, the latest timestamp in the receiver range is used.

ending-sequence

A decimal expression that identifies the ending sequence number to use. If the ending-sequence value is not found in the receiver range, an error is returned.

A value cannot be specified for both ending-timestamp and ending-sequence. This parameter cannot be specified if eof-delay is greater than zero.

If no ending sequence is specified, the last sequence number in the receiver range is used.

When ending-sequence is used, the query results will end when the first ending sequence value is encountered. If the journal has had its sequence numbers reset, ending-sequence will only return results through the first match of ending-sequence.

generate-syslog

A character or graphic string expression that indicates whether to transform journal entries into syslog formatted detail. Values are:

NO: No syslog information will be returned. The SYSLOG_EVENT, SYSLOG_FACILITY, SYSLOG_SEVERITY, and SYSLOG_PRIORITY columns will contain the null value.
RFC3164: Values will be returned for the SYSLOG_EVENT, SYSLOG_FACILITY, SYSLOG_SEVERITY, and SYSLOG_PRIORITY columns if syslog information is defined for the journal entry. The SYSLOG_EVENT column will contain a syslog header that matches the RFC3164 format as described by the Internet Engineering Task Force (IETF) Request For Comments (RFC) 3164.
RFC5424: Values will be returned for the SYSLOG_EVENT, SYSLOG_FACILITY, SYSLOG_SEVERITY, and SYSLOG_PRIORITY columns if syslog information is defined for the journal entry. The SYSLOG_EVENT column will contain a syslog header that matches the RFC5424 format as described by the Internet Engineering Task Force (IETF) Request For Comments (RFC) 5424.

DISPLAY_JOURNAL only returns syslog information for the audit journal. If RFC3164 or RFC5424 is specified, journal-library must be QSYS and journal-name must be QAUDJRN.

If generate-syslog is not specified or is the null value, NO is used.

eof-delay

An integer expression that specifies the number of seconds to sleep when all audit journal entries have been read. This delay allows the caller to establish a polling service that will continually return rows, sleeping for the specified interval whenever all entries have been processed.

A value of zero indicates no delay is used and a finite set of rows will be returned. A value greater than zero indicates that the table function will sleep, as needed, to wait for new audit journal entries and never end. If eof-delay is not specified or is the null value, zero is used.

If this parameter has a value greater than zero, the generate-syslog parameter must be RFC3164 or RFC5424, the ending-receiver-library and ending-receiver-name are ignored, and the ending-timestamp and ending-sequence parameters cannot be specified with a value other than their default values.

When using a non-zero eof-delay parameter, avoid using query clauses that depend on returning a finite number of rows. For example, using the FETCH FIRST n ROWS clause can cause the query to end when the requested number of rows has been satisfied. A query using the DISPLAY_JOURNAL function with a non-zero eof-delay parameter does not allow data to be copied (ALWCPYDTA(*NO)). This means that a query requiring a copy of data, such as one using an ORDER BY clause or UNION DISTINCT, will issue an error and not be allowed. When using eof-delay, consider using a simple query to avoid blocking of rows. When rows are blocked for data transport efficiency, rows won't be returned until the block is full. Therefore, you should decide whether you favor data transport efficiency or moving events as soon as they occur.

commit-cycle

A decimal expression that identifies the commit cycle identifier to use.

If commit-cycle is not specified, *ALL is used.

include-internal

A character or graphic string expression that indicates whether to return hidden journal entries. Hidden entries are generated and used by the system. When hidden entries are returned, it is possible to display all journal entries so all sequence numbers are accounted for.

NO: Internal entries are not returned.
YES: Internal entries are returned.

If include-internal is not specified, NO is used.

The special values supported for the function arguments are the same as for the Display Journal (DSPJRN) CL command.

The result of the function is a table containing rows with the format shown in the following table. All the columns are nullable.

Notes

Row and column access control: This table function recognizes whether ROW ACCESS CONTROL or COLUMN ACCESS CONTROL exists and is activated for the target table. If any row or column access control is active for the table, the rule text logic defined for the row permissions and/or column masks is applied before returning the value in ENTRY_DATA. When the rule text for a row permission determines that the user invoking the function should not see the row, the ENTRY_DATA column contains the text NOT AUTHORIZED. If the user is allowed to see the row and a column mask exists, the rule text for the column mask determines the value returned for ENTRY_DATA.

LOB data considerations: For journal code R (any entry type) and code F (IZ entry type), when a LOB data type is encountered that is a zero-length string, 16 'Q's are placed in the Entry Specific Data, followed by the LOB data.

Filtering considerations: When using DISPLAY_JOURNAL to review journal activity for specific objects, there are some considerations to ensure complete results are returned.

When querying the audit journal (JOURNAL_LIBRARY => 'QSYS' and JOURNAL_NAME => 'QAUDJRN'), do not use the object filters because they will result in no entries being returned. For an audit journal, use a WHERE clause to limit the rows returned.
When querying a data journal, consider whether it's possible that the Journal Identifier (JID) has changed for the object. The object filters use the JID found in the object and will not return any entries with a different JID. If the JID for the object might have changed, avoid using the object filters. In this case, use a WHERE clause to limit the rows returned.

Syslog information: Syslog information is returned for all audit journal entries with T and U journal codes. Syslog information is also available for history log messages. See HISTORY_LOG_INFO table function for more details.

The following audit journal entries with T journal codes generate syslog information:

AD: Auditing changes

Examples

Select all entries from the *CURRENT receiver of journal TESTLIB/QSQJRN.

SELECT * FROM TABLE (
                 QSYS2.DISPLAY_JOURNAL( 'TESTLIB', 'QSQJRN')) AS JT;

Find all changes made by SUPERUSER against the PRODDATA/SALES table. The first two arguments are passed without names since they correspond with the first two parameters for the function. The other four arguments are passed using the parameter name syntax to avoid specifying a value for the parameters that are not needed.

SELECT journal_code, journal_entry_type, object, object_type, X.* 
FROM TABLE (
  QSYS2.Display_Journal(
            'PRODDATA', 'QSQJRN', -- Journal library and name
            OBJECT_LIBRARY=>'PRODDATA', OBJECT_NAME=>'SALES',
            OBJECT_OBJTYPE=>'*FILE', OBJECT_MEMBER=>'SALES' 
    ) ) AS X
WHERE journal_entry_type in ('DL', 'PT', 'PX', 'UP') AND "CURRENT_USER" = 'SUPERUSER'
ORDER BY entry_timestamp DESC;

Review audit journal entries for the REQUESTS file in MYCO library. For an audit journal, a predicate is used to designate the object name.

SELECT journal_code, journal_entry_type, object, object_type, X.* 
  FROM TABLE (QSYS2.Display_Journal('QSYS', 'QAUDJRN') ) AS X 
  WHERE LEFT(OBJECT,20) = CHAR('REQUESTS', 10) CONCAT CHAR('MYCO', 10)
  ORDER BY entry_timestamp DESC;

Review changes from the last hour for the REQUESTS file in MYCO library using the current JID. This query will only find entries where the JID of MYCO/REQUESTS *FILE is an exact match to the entry. It filters for the following three journal codes:

D: Database File Operation
F: Database File Member Operation
R: Operation on Specific Record

SELECT journal_code, journal_entry_type, object, object_type, X.* 
  FROM TABLE (QSYS2.Display_Journal('MYCO', 'QSQJRN', 
            JOURNAL_CODES => 'D,F,R',

            OBJECT_MEMBER=>'*ALL'
    ) ) AS X 
  WHERE entry_timestamp > CURRENT TIMESTAMP - 1 HOUR  
  ORDER BY entry_timestamp DESC  ;

Review all changes from the last hour for the REQUESTS file in MYCO library, including any that might have a different Journal ID (JID). To see entries for all JIDs, a predicate is used to designate the object name.

SELECT journal_code, journal_entry_type, hex( journal_identifier ),

¹ The accuracy of the entry timestamp stored in journal receivers is only accurate to 16 microseconds. Hence, a value passed as a starting_timestamp and ending_timestamp will be truncated such that the actual timestamps being searched for may be from 0 to 15 microseconds less than the specified value.
