Db2 commands issued by BMC AMI Copy for read and write databases

The following tables summarize the Db2 commands issued by

BMC AMI Copy

in different scenarios as follows:

The first table shows commands issued during the UTILINIT phase for read/write database scenarios.
The second table shows commands issued during the UTILTERM phase for read/write database scenarios.

The information in the UTILINIT phase table applies to both table spaces and index spaces. However, the following rules pertain to indexes only:

Indexes are never in COPY-pending status.
If a QUIESCE is needed for the index space, the table space that the index is associated with must be quiesced since the index space cannot be quiesced directly.

Status changes made in the UTILINIT phase (R/W databases)

Scenario ¹			Db2 command issued by BMC AMI Copy ²
SHRLEVEL	Initial status ³	FULL option	-STOP	-START RO	QUIESCE	DRAIN
NONE	Any	YES or NO	Yes	No	No	No
REFERENCE	UT	YES or NO	Yes	No	No	No
REFERENCE	RO	YES or NO	No	No	Yes	No
REFERENCE	RO,COPY	YES or NO	No	No	See note ⁴	No
REFERENCE	RW	YES or NO	No	Yes	Yes	No
REFERENCE	RW,COPY	YES or NO	No	Yes	See note ⁴	No
CHANGE	Any	NO	No	No	See note ⁵	No
CONCURRENT STARTRO or LOCKTABLE	Any	YES or NO	No	Yes ^{6 7}	Yes	No
CONCURRENT DRAIN	Any	YES or NO	No	No	No	Yes

^{1 The information in this table does not apply to the table spaces DSNDB06.SYSCOPY, DSNDB01.SYSUTILX, DSNDB01.DBD01, and DSDNB01.SYSDBDXA.}

^{2 For concurrent partition or data set copies, only the first copy utility to access the space (based upon BMCUTIL table entries) modifies the status. QUIESCE BEFORE tells BMC AMI Copy to issue a QUIESCE during the UTILINIT phase when the status is not STOP or COPY.}

^{3 This is the initial status of the target table space or partition.}

^{4 If there are pages in the Db2 buffer, or if this is a data sharing subsystem, BMC AMI Copy turns off COPY-pending and issues a QUIESCE.}

^{5 If SLCHGQSC=YES and BMC AMI Copy has a problem identifying a valid LRSN, BMC AMI Copy will QUIESCE; otherwise, it will not QUIESCE. If SLCHGQSC=YES and SOFTQUIESCE=YES, it performs the DRAIN function instead of a QUIESCE. Also, DRAINWAIT, DRAINDELAY, and DRAINRETRY apply in this case.}

^{6 SHRLEVEL CONCURRENT copies restart the space in RW at the end of the UTILINIT phase unless another BMC utility has already started the space in RO or the space was originally in COPY-pending status.}

^{7 BMC AMI Copy issues the -START RO command only when READONLY is set to STARTRO. Otherwise BMC AMI Copy uses LOCK TABLE.}

The information in the UTILTERM phase table applies to both table spaces and index spaces with the exception that RESETMOD NO is always used for index copies.

Status changes made in the UTILTERM phase (R/W databases)

Scenario ¹			Db2 command issued by BMC AMI Copy ²
SHRLEVEL	Initial status ³	RESETMOD	-STOP	-START ⁴
NONE	Any	NO	No	Yes
NONE	Any	YES	No	Yes
REFERENCE	UT	NO	No	Yes
REFERENCE	UT	YES	No	Yes
REFERENCE	RO	NO	No	No
REFERENCE	RO	YES	Yes	Yes
REFERENCE	RW	NO	No	Yes
REFERENCE	RW	YES	Yes	Yes
REFERENCE	RW,COPY	NO	No	Yes
REFERENCE	RW,COPY	YES	Yes	Yes
CHANGE	Any	NO	No	No ⁵
CONCURRENT	Any	NO	No	No ⁶

^{1 The information in this table does not apply to the table spaces DSNDB06.SYSCOPY, DSNDB01.SYSUTILX, DSNDB01.DBD01, and DSDNB01.SYSDBDXA.}

^{2 For concurrent partition or data set copies, only the copy utility completing last (based upon BMCUTIL table entries) modifies the status. QUIESCE AFTER tells BMC AMI Copy to issue a QUIESCE during the UTILTERM phase when the status of the space is not STOP or COPY.}

^{3 This is the initial status of the target table space or partition.}

^{4 When BMC AMI Copy is running concurrently with another BMC utility on the same space, the last utility puts the space back to its initial status.}

^{5 If the RESETCHG installation option is set to YES, SHRLEVEL CHANGE performs a DISPLAY and compares the original status information, and if BMC AMI Copy is the last utility to relinquish control of the space, the space is returned to its initial status.}

^{6 SHRLEVEL CONCURRENT performs a DISPLAY and compares the original status information. If it is different, a START is issued at the end. If the status is COPY-pending, SHRLEVEL CONCURRENT might perform a START.}
