I am trying to scrap metric from OCI ATP database & I set the DATA_SOURCE_NAME as export DATA_SOURCE_NAME=oracle://Username:Password@Hostname:Port/Service?ssl_server_dn_match=false&wallet_location=Wallet_Location

oracledb_exporter used is 0.5.2

You should refer to go-ora to use the key and value of parameters. https://github.com/sijms/go-ora

urlOptions := map[string]string {
"TRACE FILE": "trace.log",
"AUTH TYPE":  "TCPS",
"SSL": "enable",
"SSL VERIFY": "FALSE",
"WALLET": "PATH TO WALLET"
}
connStr := go_ora.BuildUrl("server", 2484, "service", "", "", urlOptions)

The example I gave above is not correct. You should execute the BuildUrl method yourself, and the string returned is the DATA_SOURCE_NAME you want. When using ssl, the parameters should be different from the normal usage and need to be changed.

Thanks for reviewing & suggesting a solution. Actually I am a Oracle database administrator & have no knowledge on go . Below are the steps that I followed.

1. I reviewed the page https://github.com/sijms/go-ora & I downloaded the source code .

2. I installed go on linux using instructions in https://go.dev/doc/install. I copied the source code from step 1 to src directory of my go installation.

3. I created a test go file with all the details , below is the file

[oracle@######## ~]$ cat go_program.go // You can edit this code! // Click here and start typing. package main

import ( "fmt" "go-ora/v2" )

func main() { fmt.Println("Hello") urlOptions := map[string]string{ "TRACE FILE": "trace.log", "AUTH TYPE": "TCPS", "SSL": "enable", "SSL VERIFY": "FALSE", "WALLET": "/home/oracle/ATP_WALLET", } connStr := go_ora.BuildUrl("ServerName", Port, "ServiceName", "Username", "Password", urlOptions) fmt.Println(connStr)

}

4. I ran the go program in a hope that I get the connStr [oracle@######## ~]$ go run go_program.go go/go/src/go-ora/v2/connection.go:16:2: no required module provides package github.com/sijms/go-ora/v2/advanced_nego: go.mod file not found in current directory or any parent directory; see 'go help modules' go/go/src/go-ora/v2/connection.go:17:2: no required module provides package github.com/sijms/go-ora/v2/converters: go.mod file not found in current directory or any parent directory; see 'go help modules' go/go/src/go-ora/v2/auth_object.go:16:2: no required module provides package github.com/sijms/go-ora/v2/network: go.mod file not found in current directory or any parent directory; see 'go help modules' go/go/src/go-ora/v2/auth_object.go:17:2: no required module provides package github.com/sijms/go-ora/v2/network/security: go.mod file not found in current directory or any parent directory; see 'go help modules' go/go/src/go-ora/v2/connection_string.go:8:2: no required module provides package github.com/sijms/go-ora/v2/trace: go.mod file not found in current directory or any parent directory; see 'go help modules' [oracle@toolsets-app-db ~]$

Hello

I managed to get the go program executing & got below connecturl

oracle://user:pass@server:2484/service?TRACE FILE=trace.log&AUTH TYPE=TCPS&SSL=enable&SSL VERIFY=FALSE&WALLET=PATH+TO+WALLET

I then set this as DATA_SOURCE_NAME

Hello All

I came across another exporter which is based on this exporter originally & is enhanced actively --> https://github.com/oracle/oracle-db-appdev-monitoring . I was able to establish SSL connection to ATP OCI database using the exporter .

+1 for caller=collector.go:262 level=error errorpingingoracle:="unknown URL option: wallet_location" oracledb_exporter-0.5.2

Since my goal was to to connect to Oracle via TCPS port this did the trick:

orapki wallet create -wallet ./CAwallet -auto_login orapki wallet add -wallet ./CAwallet -trusted_cert -cert "Root CA.cer" orapki wallet add -wallet ./CAwallet -trusted_cert -cert "Issuing CA.cer"

export DATA_SOURCE_NAME="oracle://user:password@myhost:2484/service?SSL=enable&WALLET=/opt/oracledb_exporter/CAwallet"
