LEGATO NetWorker, Release 6.0.1-x, HP OpenVMS Version

Release Supplement

Chapter 1: NetWorker Software Release 6.0.1-D

Parallel Backup Operation Restricted (Oracle Rdb Module)

The NetWorker module for Oracle Rdb does not support both types of Rdb parallel

backups. There are two types of parallel backups. One type is a parallel backup using

threads. Rdb uses threads to do the backup when you use more than one writer in the

/LIBRARIAN=(WRITER= qualifier. The following shows an example of the

unsupported parallel backup using three writers:

$ RMU/BACKUP/LIBRARIAN=(WRITER=3) DISK$ORACLE[RDB72DB] MFP

However, the following command is supported:

$ RMU/BACKUP/LIBRARIAN=(WRITER=1) DISK$ORACLE[RDB72DB] MFP

The other type of parallel backup is initiated using the RMU/PLAN qualifier.

NetWorker does support this type of parallel backup. However there is a problem with

RMU that restrictes the number of parallel processes to 4 or less.

RMU Tracing Feature Not Supported (Oracle Rdb Module)

The NetWorker module for Oracle Rdb does not support the use of the TRACE and

LEVEL switches in an RMU/LIBRARIAN command. For example:

RMU/LIBRARIAN=(TRACE=filespec,LEVEL=level)

To cause the NetWorker software to write debug and trace messages to a specified file,

you must define the following NetWorker logical names before beginning the database

backup:

• NSR_DEBUG_FILE

• NSR_DEBUG_LEVEL

It is recommended that you deassign these logical names after the backup operation

completes. Refer to the LEGATO NetWorker Administrator’s Guide, Release 6.0.1-D, HP

OpenVMS Alpha Version for more information.

RMU/LIBRARY/LIST Does Not Support Wildcards (Oracle Rdb Module)

The RMU program supports a function that queries the librarian catalog. In the case of

NetWorker, this function queries the media and file indexes. The format for the RMU

list command is:

RMU/LIBRARY/LIST <saveset-name>

In general, RMU appends the string .RBF to any name supplied by the NetWorker Rdb

backup template file. Thus, if you use the template file, the resulting save set names are

of the form: <BACKUP_NAME><DATE-TIME>.RBF, where <BACKUP_NAME> is the

string assigned to the BACKUP_NAME symbol within the backup procedure, and

<DATE-TIME> is the date and time of the backup. The RMU/LIBRARY/LIST

command works correctly only when the fully specified save set name is provided as

shown in the following example:

$ rmu/library/list corporate_data_2003-10-30_091311.RBF

LIBRARIAN BACKUP FILES

BACKUP NAME: CORPORATE_DATA_2003-10-30_091311.RBF
