>>> how to log a odbc connection with tcpdump
A clever question!
To log an ODBC (Open Database Connectivity) connection using `tcpdump`, you’ll need to capture the TCP packets that are exchanged between your application
and the database server. Here’s a step-by-step guide:
**Prerequisites:**
1. You have `tcpdump` installed on your system.
2. Your application uses ODBC to connect to the database server.
3. The database server listens for incoming connections on a specific TCP port (e.g., 5432 for PostgreSQL or 3306 for MySQL).
**Capturing ODBC connection packets:**
1. Identify the TCP ports used by your application and the database server. For example, if your application uses ODBC to connect to a PostgreSQL database
listening on port 5432, you’ll want to capture packets on that port.
2. Run `tcpdump` with the following options:
„`
tcpdump -n -vv -s 0 -c 1000 -W 1024 -i any port 5432
„`
Here’s what each option does:
* `-n`: Don’t resolve hostnames (use IP addresses instead).
* `-vv`: Increase verbosity for more detailed output.
* `-s 0`: Capture packets of all sizes, including small ones.
* `-c 1000`: Limit the capture to 1000 packets.
* `-W 1024`: Set the maximum packet size to 1024 bytes (adjust this value if you need to capture larger packets).
* `-i any`: Capture traffic on any interface (e.g., `eth0`, `wlan0`, etc.).
* `port 5432`: Specify the port number to capture traffic for (in this case, PostgreSQL’s default port).
**Capturing ODBC connection establishment:**
To capture the exact moment when an ODBC connection is established, you can use a filter to capture only the initial handshake packets.
1. Run `tcpdump` with the following options:
„`
tcpdump -n -vv -s 0 -c 1000 -W 1024 -i any port 5432 ‚tcp src port 32773 and tcp dst port 5432‘
„`
Here’s what this filter does:
* `tcp`: Capture TCP packets.
* `src port 32773`: Only capture packets with the source port set to 32773 (a common ODBC port).
* `dst port 5432`: Only capture packets with the destination port set to 5432 (the PostgreSQL port).
**Analyzing captured packets:**
Once you’ve captured the ODBC connection packets, you can use tools like `tcpdump` or `Wireshark` to analyze them. You can filter the captured packets by
protocol (e.g., TCP), port numbers, or specific packet contents.
In Wireshark, for example, you can:
1. Open the capture file.
2. Apply a filter using the „Apply a display filter“ option.
3. Use the `tcp` protocol filter to see only TCP packets.
4. Look for packets with the source port set to 32773 (ODBC) and destination port set to 5432 (PostgreSQL).
By analyzing these packets, you should be able to see the ODBC connection establishment process, including the initial handshake, authentication, and data
transmission.
Keep in mind that capturing network traffic can reveal sensitive information about your system and database. Make sure to use `tcpdump` or other capture
tools responsibly and with caution.

>>> how to disable compression in oracle rman backup
By default, Oracle RMAN (Recovery Manager) compresses the backup data to reduce storage requirements and improve transfer times. However, there may be
scenarios where you want to disable compression for specific backups or for a particular reason.
To disable compression in an Oracle RMAN backup, you can use the `COMPRESSION` parameter with a value of `OFF` when executing the `BACKUP` command. Here
are some examples:
1. Disable compression for a single backup:
„`sql
RMAN> BACKUP DATABASE COMPRESSION OFF;
„`
This will create a compressed backup of your entire database.
2. Disable compression for a specific tablespace or datafile:
„`sql
RMAN> BACKUP TABLESPACE <tablespace_name> COMPRESSION OFF;
„`
Replace `<tablespace_name>` with the name of the tablespace you want to back up without compression.
3. Disable compression for a specific database file (e.g., an individual datafile):
„`sql
RMAN> BACKUP FILE ‚<datafile_name>‘ COMPRESSION OFF;
„`
Replace `<datafile_name>` with the full path and name of the database file you want to back up without compression.
4. Set the default compression setting for all future backups:
„`sql
RMAN> CONFIGURE DEFAULT DEVICE TYPE TO ‚DISK‘ COMPRESSION OFF;
„`
This sets the default compression setting for all subsequent backups that use the `BACKUP` command with no specific compression setting specified.
Remember to adjust the `COMPRESSION` parameter according to your specific requirements and storage constraints.
