1. Select the Administration icon then choose Assign System
to Business Unit
2. Press the Bulk Mapping button
7
Bulk Map Systems to Business Units
• If you have a large number of systems, these can be mapped quickly to business units in Collection Manager via an XML bulk upload
3. Upload a mapping XML
a) Press the Generate XML File (Current Mapping) button
b) Download the resulting XML file underneath, which will contain your current system to
business unit mappings
c) Amend the XML to show mappings you desire
d) Upload new Mapping XML via Upload Mapping (XML File) button

1. Select the Administration icon then choose Manage Users,
User Roles and assign System to users
2. To disable the automatic capture of users details press the
button Don’t Capture User Details (When Login)
3. If you want to re-enable the automatic capture of user details
press the button Capture User Details (When Login)
Selectively Capture Users During Login
• By default users logging in via LDAP authentication
are captured and provided the DBA role
• You can choose to disable this automatic capture.
Note: This means you will need to manually create users instead and assign the
necessary role.1

$ ./orachk -setdbupload all
Enter value for
RAT_UPLOAD_CONNECT_STRING:(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=myserver44.acompany.com
)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orachkcm.acompany.com)))
Enter value for RAT_UPLOAD_PASSWORD:******
Database upload parameters successfully stored in orachk_wallet. orachk run will keep
uploading the collections in database until it is unset using ./orachk -unsetdbupload
all/<env variable name>
9
Configure Details for Upload of Collection Results
• Collection Manager upload configuration only requires connection string & connection password
• The required connection details can be specified using –setdbupload
• You will then be prompted to enter the values for the connection string and password
• These values will be stored in the encrypted wallet file.
./orachk -setdbupload all ./exachk -setdbupload allor

$ ./orachk –getdbupload
RAT_UPLOAD_CONNECT_STRING =
(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=myserver44.acompany.com)(PORT=1521))(CONNECT_DATA
=(SERVER=DEDICATED)(SERVICE_NAME=orachkcm.acompany.com)))
RAT_UPLOAD_PASSWORD = ******
RAT_UPLOAD_USER = ORACHKCM
RAT_ZIP_UPLOAD_TABLE = RCA13_DOCS
10
• To see the values which have been set in the wallet use –getdbupload :
./orachk -getdbupload ./exachk -getdbuploador

Tip: To configure many ORAchk/EXAchk instances
1. Create wallet once with: -setdbupload all then enter values when
prompted
2. Copy resulting wallet to each ORAchk/EXAchk location
The environment variable RAT_WALLET_LOC can also be used to point to
the location of the wallet directory.
$ ./orachk -checkdbupload
Configuration is good to upload result to database.
• Verify ORAchk/EXAchk can make successful connection to the database for upload using –checkdbupload:
• If connection details are set ORAchk/EXAchk will attempt to upload the results at the end of Health Check
collection
11
./orachk -checkdbupload ./exachk -checkdbuploador

Other Upload Parameters Note Set by default Description
RAT_UPLOAD_USER The user to connect as (default is ORACHKCM)
RAT_UPLOAD_TABLE The table name to store non-zipped collection results
RAT_PATCH_UPLOAD_TABLE The table name to store non-zipped patch results
RAT_UPLOAD_ORACLE_HOME The ORACLE_HOME used during establishing connection and
uploading.
(Uses GI HOME discovered by ORAchk/EXAchk by default)
RAT_UPLOAD_TABLE &
RAT_PATCH_UPLOAD_TABLE
Only needed if you are using your own custom application to view
collection results, rather than Collection Manager.
• If you are using your own custom application to view collection results, rather than Collection Manager, follow this process:
1. Set default parameters:
– This will prompt you for and set the RAT_UPLOAD_CONNECT_STRING & RAT_UPLOAD_PASSWORD
2. Set optional parameters for RAT_UPLOAD_TABLE & RAT_PATCH_UPLOAD_TABLE
12
./orachk –setdbupload all ./exachk –setdbupload all
./orachk -setdbupload RAT_UPLOAD_TABLE,RAT_PATCH_UPLOAD_TABLE
./exachk -setdbupload RAT_UPLOAD_TABLE,RAT_PATCH_UPLOAD_TABLE
or
or
Note: RCA13_DOCS is no
longer configurable if you
wish to use Collection
Manager

• Uploaded collections are now purged from Collection Manager
• By default collections older than 3 months are purged
• To adjust or disable the collection purging frequency:
1. Select the Administration icon then choose Manage Email Server & Job Details
2. Select the appropriate option for purge frequency

• Track changes to the attributes of important files with –fileattr
– Looks at all files & directories within Grid Infrastructure and Database homes by default
– The list of monitored directories and their contents can be configured to your specific requirements
– Use –fileattr start to start the first snapshot
15
$ ./orachk -fileattr start
CRS stack is running and CRS_HOME is not set. Do you want to set CRS_HOME to
/u01/app/11.2.0.4/grid?[y/n][y]
Checking ssh user equivalency settings on all nodes in cluster
Node mysrv22 is configured for ssh user equivalency for oradb user
Node mysrv23 is configured for ssh user equivalency for oradb user
List of directories(recursive) for checking file attributes:
/u01/app/oradb/product/11.2.0/dbhome_11203
/u01/app/oradb/product/11.2.0/dbhome_11204
orachk has taken snapshot of file attributes for above directories at:
/orahome/oradb/orachk/orachk_mysrv21_20160504_041214
./orachk –fileattr start ./exachk –fileattr startor

• Include other directories with –includedir <directories> using a comma separated list of directories
./orachk –fileattr start includedir “/home/oradb,/etc/oatab”
./exachk –fileattr start includedir “/home/oradb,/etc/oatab”
or
• Exclude the default discovered directories with –excludediscovery
./orachk –fileattr start includedir “/home/oradb,/etc/oatab” -excludediscovery
./exachk –fileattr start includedir “/home/oradb,/etc/oatab” -excludediscovery
or

Note:
• Use the same arguments with check that you used with start
• Will proceed to perform standard health checks after attribute checking
• File Attribute Changes will also show in HTML report output
• Compare current attributes against first snapshot using –fileattr check
17
$ ./orachk -fileattr check -includedir "/root/myapp/config" -excludediscovery
CRS stack is running and CRS_HOME is not set. Do you want to set CRS_HOME to

…etc
./orachk –fileattr check ./exachk –fileattr checkor
• Results of snapshot comparison will also
be shown in the HTML report output

• To prevent standard health checking after attribute checking add –fileattronly:
• To use a different snapshot baseline use –baseline:
• To remove all snapshot use –fileattr remove
18
./orachk –fileattr check –fileattronly ./exachk –fileattr check –fileattronlyor
./orachk -fileattr check -baseline <snapshot> ./exachk -fileattr check -baseline <snapshot>or
