Depending on other command options or system conditions, some additional detail lines are present within the report block:

• DSNJ370I Output

• DSNJ375I Output

DSNJ370I Output

The output from this command has the following general structure:

DSNJ370I csect-name LOG DISPLAY
CURRENT COPY1 LOG = dsname1 IS pct1% FULL 
KEY LABEL = keylabel-name1
CURRENT COPY2 LOG = dsname2 IS pct2% FULL 
KEY LABEL = keylabel-name2
          H/W RBA = hw-rba
          H/O RBA = ho-rba
          FULL LOGS TO OFFLOAD = full-count OF total-count
          OFFLOAD TASK IS status
          SOFTWARE ACCELERATION IS ENABLED
          ZHYPERLINK WRITE IS ENABLED
            LAST LOG WRITE FOR COPY1 USED ZHYPERLINK
            LAST LOG WRITE FOR COPY2 DID NOT USE ZHYPERLINK

          time-date-2

csect-name

The name of the control section that issued the message.

dsname1

The name of the current active log COPY 1 data set. This data set is used for the first copy of the active log. If the value for dsname1 is INACTIVE, this copy of the log is not currently active.

pct1

The percentage of log space in the active log COPY 1 data set that has been used for writing log records.

dsname2

The name of the current active log COPY 2 data set. This data set is used for the second copy of the active log. If the value for dsname2 is INACTIVE, this copy of the log is not currently active.

keylabel-name1

The key label name that was used to encrypt the active log COPY1 data set.

pct2

The percentage of log space in the active log COPY 2 data set that has been used for writing log records.

keylabel-name2

The key label name that was used to encrypt the active log COPY2 data set.

hw-rba

The RBA of the most recently written log record.

ho-rba

The highest log RBA that has been offloaded to an archive log data set.

full-count

The number of full active log data sets that have not been archived.

total-count

The total number of active log data sets.

status

The status of the offload task. status can be one of the following values:

BUSY,ALLC

The task is busy allocating an archive log data set. This status might indicate that a tape mount request is outstanding.

BUSY,BSDS

The task is busy copying the bootstrap data set (BSDS).

BUSY,ACTV

The task is busy copying an active log data set.

BUSY

The task is busy with other processing.

AVAILABLE

The task is available for work.

accel-status

The status of software-controlled mirroring, either ENABLED or DISABLED based on the setting of the REMOTE_COPY_SW_ACCEL subsystem parameter.

zhyperlink-status

The status of the ZHYPERLINK Db2 zparm, either ENABLED or DISABLED based on the setting of ZHYPERLINK Db2 parameter (shows enabled when the value is ZHYPERLINK=ENABLE or ZHYPERLINK=ACTIVELOG).

If the ZHYPERLINK Db2 system parameter is set to ENABLE or ACTIVELOG, DFSMS does a zhyperwrite implicitly, even if the REMOTE_COPY_SW_ACCEL Db2 system parameter is not enabled.

copy1 zhyperlink last IO status

LAST LOG WRITE status shows whether ZHYPERLINK was used successfully for the copy1 active log.

If the ZHYPERLINK Db2 zparm is enabled and all of the required prerequisites are in place for exploiting ZHYPERLINK write, the LAST LOG WRITE message should show successful ZHYPERLINK writes. If the message NOT USED is shown consistently, refer to this link for the required prerequisites for ZHYPERLINK write.

copy2 zhyperlink last IO status

LAST LOG WRITE status shows whether ZHYPERLINK was used successfully for the copy2 active log.

If the ZHYPERLINK Db2 zparm is enabled and all of the required prerequisites are in place for exploiting ZHYPERLINK write, the LAST LOG WRITE message should show successful ZHYPERLINK writes. If the message NOT USED is shown consistently, refer to this link for the required prerequisites for ZHYPERLINK write.

DSNJ371I Output

There are two possible outputs for DSNJ371I, depending on the CHKTYPE subsystem parameter values.

When the number of minutes and the number of log records are used to determine the checkpoint frequency, the output has the following structure:

 DSNJ371I  DB2 RESTARTED time-date-1
          RESTART RBA rstrt-rba
          CHECKPOINT FREQUENCY quantity-and-type
          LAST SYSTEM CHECKPOINT TAKEN 

When both the number of minutes and the number of log records are used to determine the checkpoint frequency, the output includes the following alternative form of message DSNJ371I, which shows both values:

DSNJ371I  DB2 RESTARTED time-date-1
          RESTART RBA rstrt-rba
          CHECKPOINT FREQUENCY quantity-and-type OR quantity-and-type
          LAST SYSTEM CHECKPOINT TAKEN time-date-2

time-date-1

The time and date when Db2 started.

rstrt-rba

The RBA that Db2 began logging when it started.

quantity-and-type

The number of minutes or the number of log records that determine the current checkpoint frequency.

time-date-2

The time and date of the last system checkpoint.

DSNJ375I Output

When the log is on a member of a data sharing group that is a component of a GDPS® Continuous Availability with zero data loss solution, message DSNJ375I follows message DSNJ371I.

DSNJ375I csect-name CDDS DSNAME=dsname3 IS cdds-status IN
          cdds-mode MODE.

csect-name

The name of the control section that issued the message.

dsname3

The name of the compression dictionary data set (CDDS) that interprets the log.

cdds-status

The status of the CDDS. cdds-status can be one of the following values:

ACTIVE

The CDDS is accessible for read/write access in the source data sharing group. The CDDS is accessible for read/only access in the proxy data sharing group.

INACTIVE

The CDDS is not accessible for read/write access in the source data sharing group. The CDDS is not accessible for read/only access in the proxy data sharing group.

cdds-mode

The purpose of the data sharing group to which the log belongs:

SOURCE

The data sharing group supports replication of its log data sets by another data sharing group.

PROXY

The data sharing group supports replication of log data sets for another data sharing group.
