Install and Run TFA without Root Privileges
• TFA can now be installed as the ORACLE_HOME owner:
– Will not run a daemon
– Will not perform automatic collections
– Will not collect from remote hosts
– On-demand collections will work, but limited to local files you have read access to
• Use the JRE already available in the RDBMS home unless you have a later version available
• Where multiple DBA users own different ORACLE_HOMEs, install TFA in different locations as the respective users
6
./installTFALite -extractto <install_dir> -javahome <jre_home>
Where possible you should install TFA as root
This option is for the cases where that is not an option

One Command SRDCs
• For certain types of problems Oracle Support will ask you to run a Service Request Data Collection (SRDC)
• Previously this would have involved: – Reading many different support documents
– Collecting output from many different tasks
– Gathering lots of different diagnostics
– Packaging & uploading
• TFA can now run SRDC collections for you with a single command:
tfactl diagcollect -srdc <srdc_type>

SRDCs for ORA errors:
• ora600
• ora7445
• ora700
• ora4031
• ora4030
• ora27300
• ora27301
• ora27302

Manual Data Gathering vs One Command SRDC
Manual Data Gathering
1. Generate ADDM reviewing Document 1680075.1
2. Identify “good” and “problem” periods and gather AWR reviewing Document 1903158.1
3. Generate AWR compare report (awrddrpt.sql) using “good” and “problem” periods
4. Generate ASH report for “good” and “problem” periods reviewing Document 1903145.1
5. Collect OSWatcher data reviewing Document 301137.1
6. Check alert.log if there are any errors during the “problem” period
7. Find any trace files generated during the “problem” period
8. Collate and upload all the above files/outputs to SR
TFA SRDC
1. Run
2. Upload resulting zip file to SR
tfactl diagcollect –srdc dbperf

1. Enter default for event date/time and database name
2. Scans system to identify recent 10 events in the system (ORA600 example shown)
3. Once the relevant event is chosen, proceeds with diagnostic collection

Bash no Longer Required
• TFA will use a different mechanism for discovery if bash is not available
• None bash discovery mechanism will not discover non-ADR-standard configurations: – i.e. If your diag directory is not in ORACLE_BASE
– However any directories that are missed by the discovery can be easily added using the directory add command:
• If bash is available it will still be used for discovery, in which case location of diag directory does not matter
16
tfactl directory add <dir_path>
