6.9 Performing Custom Collections

Use the custom collection options to change the diagnostic collections from the default.

6.9.1 Adjusting the Diagnostic Data Collection Period

Oracle Trace File Analyzer trims and collects any important logs updated in the past one hour.

If you know that you only want logs for a smaller window, then you can cut this collection period. Cutting the collection period helps you make collections as small and quick as possible.

There are four different ways you can specify the period for collection:

Table 6-7 Ways to Specify the Collection Period

Command Description

tfactl diagcollect -last n h|d

Collects since the previous n hours or days.

  • Number of days must be less than or equal to 7
  • Number of hours must be less than or equal to 168

tfactl diagcollect -from “yyyy-mm-dd

Collects from the date and optionally time specified.

Valid date and time formats:

"Mon/dd/yyyy hh:mm:ss"

"yyyy-mm-dd hh:mm:ss"

"yyyy-mm-ddThh:mm:ss"

"yyyy-mm-dd"

tfactl diagcollect –from "yyyy-mm-dd" -to "yyyy-mm-dd"

Collects between the date and optionally time specified.

Valid date and time formats:

"Mon/dd/yyyy hh:mm:ss"

"yyyy-mm-dd hh:mm:ss"

"yyyy-mm-ddThh:mm:ss"

"yyyy-mm-dd"

tfactl diagcollect -for “yyyy-mm-dd

Collects for the specified date.

Valid date formats:

"Mon/dd/yyyy"

"yyyy-mm-dd"

6.9.2 Collecting for Specific Events

Perform default diagnostic collection or choose an event from the list of recent incidents to collect diagnostic data for that event alone.

Choose to run:

  • A diagnostic collection for a specific recent event
  • A default time range diagnostic collection

To collect for specific events:

  1. To run a default diagnostic collection:
    tfactl diagcollect
    For example:
    $ tfactl diagcollect
    Choose the event you want to perform a diagnostic collection for:

    Please choose the event : 1-10 [] 10

6.9.3 Excluding Large Files from Diagnostic Collection

Prevent excessively large files from delaying or stalling collections.

Run the tfactl set maxfilecollectionsize for the diagnostic collection command to consider only the last 200 KB for the files that are larger than the size specified.

  1. To set the maximum file size:
    tfactl set maxfilecollectionsize=size_in_MB
  2. To collect diagnostic data:
    tfactl diagcollect

6.9.4 Collecting from Specific Nodes

To collect from specific nodes:

  1. To collect from specific nodes:
    tfactl diagcollect –node list of nodes
    For example:
    $ tfactl diagcollect -last 1d -node myserver65

6.9.6 Collecting from Specific Directories

Oracle Trace File Analyzer discovers all Oracle diagnostics and collects relevant files based on the type and last time updated.

If you want to collect other files, then you can specify extra directories. Oracle Trace File Analyzer collects only the files updated in the relevant time range (one hour by default).

You can configure collection of all files irrespective of the time last updated. Configure on a directory by directory basis using the -collectall option.

To collect from specific directories:

  1. To include all files updated in the last one hour:
    tfactl diagcollect –collectdir dir1,dir2,...dirn

    For example:

    To trim and collect all Oracle Clusterware files updated in the last one hour as well as all files from /tmp_dir1 and /tmp_dir2 at the initiating node:
    $ tfactl diagcollect –crs –collectdir /tmp_dir1,/tmpdir_2
  2. To configure Oracle Trace File Analyzer to collect all files from a directory, first configure it with the -collectall option:
    $ tfactl add dir -collectall

    or

    tfactl modify dir -collectall
    Start a diagnostic collection using the -collectalldirs option:
    $ tfactl diagcollect -collectalldirs

    Note:

    If the -collectalldirs option is not used normal, then the file type, name, and time range restrictions are applied.

6.9.7 Changing the Collection Name

Oracle Trace File Analyzer zips collections and puts the zip files in the repository directory using the following naming format:

repository/collection_date_time/node_all/node.tfa_date_time.zip

You must only change the name of the zipped files using the following options. Manually changing the file name prevents you from using collections with various Oracle Support self-service tools.

To change the collection name:

  1. To use your own naming to organize collections:
    –tag tagname

    The files are collected into tagname directory inside the repository.

  2. To rename the zip file:
    –z zip name

6.9.8 Preventing Copying Zip Files and Trimming Files

By default, Oracle Trace File Analyzer Collector:

  • Copies back all zip files from remote notes to the initiating node

  • Trims files around the relevant time

To prevent copying zip files and trimming files:

  1. To prevent copying the zip file back to the initiating node:
    –nocopy
    For example:
    $ tfactl diagcollect -last 1d -nocopy
  2. To avoid trimming files:
    –notrim
    For example:
    $ tfactl diagcollect -last 1d -notrim

6.9.9 Performing Silent Collection

  1. To initiate a silent collection:
    –silent

    The diagcollect command is submitted as a background process.

    For example:
    $ tfactl diagcollect -last 1d -silent

tfactl ips show package

Shows all IPS Packages.

tfactl diagcollect -ips -h

Shows all available diagcollect IPS options.

tfactl diagcollect -ips

Performs an IPS collection following prompts. You can use all the standard diagcollect options to limit the scope of IPS collection.

tfactl diagcollect -ips -adrbasepath adr_base -adrhomepath adr_home

Performs an IPS collection in silent mode.

tfactl diagcollect -ips -incident incident_id
