Granting authority to replication objects on the System i for an user to run Datapropagator Apply

Question & Answer


Question

How to grant authority to replication objects on the System i for an user to run Datapropagator Apply ?

Answer

The authority to replication objects on the System i could be granted using the QDP4/GRTDPRAUT and the GRTOBJAUT commands.

The link below discusses the authorization requirements for the Apply program on System i -

http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/index.jsp?topic=/com.ibm.swg.im.iis.db.repl.sqlrepl.doc/topics/iiyrsautapply.html

The commands have to be run by an user with *ALLOBJ authority.

The GRTDPRAUT AUT(*APPLY) command and the authorizations granted to the replication objects are described in the following section -

http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/index.jsp?topic=/com.ibm.swg.im.iis.db.repl.iseries.doc/topics/iiyrsisegrtdpraut.html


In addition to the above if the userid running Capture is different from the id running Apply you will also need *CHANGE authority on the IBMSNAP_PRUNE_SET table and the indexes such as IBMSNAP_PRUNE_SETX,
IBMSNAP_PRUNCNTLX
IBMSNAP_PRUNCNTLX1
IBMSNAP_PRUNCNTLX2
IBMSNAP_PRUNCNTLX3
that is not listed in the link above.

Hence it is necessary to manually grant this authority using the GRTOBJAUT command.

The steps involved will be similar to -
1) Determine the system names for the Table or Index

Run the command WRKOBJ OBJ(<schema>/IBMSN*) and find the system names corresponding to the SQL names IBMSNAP_PRUNE_SET and IBMSNAP_PRUNE_SETX,IBMSNAP_PRUNCNTLX, IBMSNAP_PRUNCNTLX1, IBMSNAP_PRUNCNTLX2, IBMSNAP_PRUNCNTLX3

For example -
WRKOBJ OBJ(ASN/IBMSN*) will list all objects starting with IBMSN.
IBMSN00019 *FILE ASN PF IBMSNAP_PRUNE_SET
IBMSN00020 *FILE ASN LF IBMSNAP_PRUNE_SETX
From it find the system names of interest - IBMSN00019 and IBMSN00020.

If needed the index on the table can also be found using the DSPDBR command on the base table.

2) Then use the GRTOBJAUT command to grant the necessary authorization.

GRTOBJAUT OBJ(<schema>/<systemname>) OBJTYPE(*ALL) USER(<userid>) AUT(*CHANGE)

For example -
GRTOBJAUT OBJ(ASN/IBMSN00019) OBJTYPE(*ALL) USER(APPUSER) AUT(*CHANGE)
GRTOBJAUT OBJ(ASN/IBMSN00020) OBJTYPE(*ALL) USER(APPUSER) AUT(*CHANGE)


Please note that the commands above grant authority to existing objects on the System i only. So some additional objects will require authorizations to be granted using the GRTOBJAUT command after replication is started.

The section below describes two such cases

a) SQL packages are required to be created on all the remote servers the Apply program will connect to. This is done every time a PTF is applied for replication or a Fixpack applied on workstations running Apply.

The SQL packages of type *SQLPKG will be created in the ASN library if the Apply runs on the System i and in the library NULLID if Apply runs on a Z-os or LUW platform.

Usually these packages are created with *PUBLIC authority but if it is required to restrict the authority then *CHANGE authority could be granted to them using the GRTOBJAUT command.

b) The table with the SQL name format of IBMSNAP_SIGNAL_jrnlib_jrnname is created for each journal that a source table is journalled to by the System i Capture when it initially starts up .

http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/index.jsp?topic=/com.ibm.swg.im.iis.db.repl.sqlrepl.doc/topics/iiyrsctbsignal.html

So *CHANGE authorization for this table and its index should be granted using the GRTOBJAUT command after it is created.

Not having sufficient authority will cause MSGSQL0551 or MSGSQL0443 errors when running Apply.
