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 all or


$ ./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

Configure Details for Upload of Collection Results • To see the values which have been set in the wallet use –getdbupload :

./orachk -getdbupload ./exachk -getdbupload or


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

Configure Details for Upload of Collection Results

./orachk -checkdbupload ./exachk -checkdbupload or


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

Configure Details for Upload of Collection Results

./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 start or

Copyright © 2016, Oracle and/or its affiliates. All rights reserved. | 16


• 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

/u01/app/12.2.0/grid?[y/n][y]

Checking for prompts on myserver18 for oragrid user...

Checking ssh user equivalency settings on all nodes in cluster

Node myserver17 is configured for ssh user equivalency for root user

List of directories(recursive) for checking file attributes:

/root/myapp/config

Checking file attribute changes...

.

"/root/myapp/config/myappconfig.xml" is different:

Baseline : 0644 oracle root /root/myapp/config/myappconfig.xml

Current : 0644 root root /root/myapp/config/myappconfig.xml

…etc

…etc

./orachk –fileattr check ./exachk –fileattr check or

• Results of snapshot comparison will also be shown in the HTML report output


Keep Track of Changes to the Attributes of Important Files • 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 –fileattronly or

./orachk -fileattr check -baseline <snapshot> ./exachk -fileattr check -baseline <snapshot> or

./orachk -fileattr remove ./exachk -fileattr remove or
