Performance Tuning for Content Manager

422 Performance Tuning for Content Manager

There are several types of Resource Manager/Library Server reports:

Orphan Entries are added to the ORPHAN report if an object is on

the Resource Manager but the Library Server does not have

a reference to the object. The report contains information

about the object from the Resource Manager database.

Not in RM Entries are added to the NOTINRM report if the Library

Server has a reference to an object but the object is not on

the Resource Manager. The report contains information

about the object from the Library Server database.

Size mismatch Entries are added to the SIZEMISMATCH report if the size of

an object on the Library Server does not match the size of an

object on the Resource Manager. The report contains

information about the object from the Resource Manager

and Library Server databases.

Collection mismatch

Entries are added to the COLLECTION report if the

collection of an object on the Library Server does not match

the collection of an object on the Resource Manager. The

report contains information about the object from the

Resource Manager and Library Server databases.

Date mismatch Entries are added to the DATEMISMATCH report if the object

update date on the Library Server does not match the object

update date on the Resource Manager. Under normal

circumstances, if there is any synchronization problem

between the Library Server and the Resource Manager, the

object update date does not match. In order to reduce

redundant entries in the different reports, entries are not

added to the DATEMISMATCH report if they have been

added to the collection mismatch or size mismatch reports.

The report contains information about the object from the

Resource Manager and Library Server databases.

14.7.7 Resource Manager volume validation utility

The Resource Manager volume validation utility checks each object in its

database that was added or changed in a specified date range. It queries the

device manager for the attributes of that object and generates reports for each

object whose information in the database is different than reported by the device

manager. You might want to use the utility if you have a restore data on a volume

after a volume crash. The utility helps you to verify that the data is restored

correctly. The Resource Manager must be running when you use the utility.

Chapter 14. Maintenance 423

The validation utility does not search the storage system for orphaned objects

(objects not referenced by the Resource Manager). Because of the wide variety

of storage systems that are often used for storing files other than those managed

by Content Manager, scanning for orphaned files can be extremely time

consuming and might produce a large quantity of false positives.

The Resource Manager volume validation utility runs on the Resource Manager

server and only requires access to its own database and the device managers

responsible for the volumes that are being checked.

Starting the Resource Manager volume validation utility

The Resource Manager volume validation utility is icmrmvolval.sh or

icmrmvolval.bat. To start the utility, navigate to the bin directory in the Resource

Manager home directory.

The Resource Manager volume validation program uses specific input

parameters (Table 14-3). Both dashes (-) and forward slashes (/) are handled as

the parameter separator. The parameter tags are supported in both lower case

and upper case.

Table 14-3 Resource Manager volume validation utility parameters

Tip: Use the Resource Manager volume validation utility during times of low

traffic on the Resource Manager.

Parameter Description

-B YYYY-MM-DD-HH.MM.SS The beginning time and date of the objects to

examine. Use this parameter with the -E

parameter to restrict the number of objects that the

utility must examine. This parameter is optional. If

it is not present, all of the objects prior to the -E

date are returned, or all of the objects are returned

if -E is also not defined.

-E YYYY-MM-DD-HH.MM.SS The ending time and date of the objects to

synchronize. Use this parameter with the -B

parameter to restrict the number of objects that the

utility must examine. This parameter is optional. If

it is not present, all of the objects after the -B date

are returned, or all of the objects are returned if -B

is also not defined.

-F output-path The absolute path to be used for the output files.

The utility creates the UTF-8 XML files in this

directory. This parameter is required. If the files

currently exist, they are overwritten.
