The following report shows an example of a complete LOGR inventory
list; it is followed by individual field descriptions and output explanations.
The output of this report will contain the characteristics of the
log stream, the connection information, and a list of the offload
data sets. You can use an asterisk (*) in place of the log stream
name and structure name to list all log streams and structures.

Time Defined: 02/25/02 17:32:22 (GMT)UNKNOWN appears in place of the date and time if
both of the following situations occur:
- The log stream has been defined on a pre-OS/390 V1R3 release in an HBB5520 format level LOGR CDS
- The log stream had not been connected or updated since on a HBB6603 or HBB7705 format level LOGR CDS
Figure 4 shows an example if an empty
data set that has not been written to. The field descriptions are
as follows:
- Ext. is the couple data set extent number. An * in front of the number indicates the extent is in the base directory of the log stream record.
- <SEQ#> is the data set sequence number—that is, the low level qualifier.
- Lowest Blockid indicates the lowest (oldest) log block in the data set.
- Highest GMT indicates the highest Time Stamp of the last blockid written in the data set, expressed in GMT format.
- Highest Local indicates the same time as Highest GMT, express in local time format.
- Status indicates the state of the data set.
- Highest Blockid indicates the highest log block in the data set.
- Highest RBA indicates the relative byte address of the highest used block in the data set.
- System Name is the name of the system that last changed the state of the data set. The state of the data set changes when the data set is newly allocated, closed, or marked for deletion. System Name does not name the last system to write to the dataset.

sets that have been written to. The Status of
the data sets can be:
- DELETE PENDING specifies the data set is being used by another logger process. The system logger deletes the data set the next time an offload data set is allocated for that particular log stream.
- DELETED indicates that system logger has
deleted the data set from its directory and the data set has been
physically deleted. Note: This status occurs when there is an older offload data set in the DELETE PENDING status.
- CURRENT is the data set currently being written to.
- I/O Error indicates that the system logger has received an I/O error trying to access this data set.

000000000F02E45A 00007D5C SYSTEM_1The system name is updated when the data set status
is changed. System Name means the follows if the Status is:
- DELETE or DELETE PENDING indicates the system that deletes the data set.
- Blank or I/O Error indicates the system that filled in the Lowest Blockid,Highest GMT, Highest Local,Highest Blockid and Highest RBA for this data set.
- CURRENT indicates the system that defined the data set. The System Name might appear blank if a pre-V1R10 system defines this data set.
System Name might appear as blank if a pre-V1R10 system updated the data set status.
System logger cannot determine the Highest Blockid field occasionally. The situation happens when a pre-V1R10 system fills the data set and sets the Lowest Blockid,Highest GMT, Highest Local, and Highest RBA. The Highest Blockid is set to ****UNKNOWN**** if system logger cannot determine the block ID.
For the current offload data set, the following fields
might be filled as blanks or zeroes if they are created, but not yet
written to.
- Lowest Blockid
- Highest GMT
- Highest Local
- Highest Blockid
- Highest RBA
An orphaned data set is a data set that logger does not know about
in the data set directory, but has not been physically deleted. This
might indicate a procedural problem. Figure 6 shows
an example of an orphaned data set. Delete an orphaned data set manually
if it is not useful.
Note:
- If logger encounters an error scanning the catalog for orphan
data sets, it will append the following message to the existing orphaned
data set section:
CATALOG ERROR - ORPHAN LIST MAY BE INCOMPLETE - One exception occurs when the next current data set shows up on the orphaned data set list. This is a timing issue. System logger has to successfully allocate the data set before it updates its directory to contain the data set. Do not manually delete the data set if this is the case.

could be a duplication of the last resource processed in the report
