Mengapa saya mendapatkan kesalahan format:Properti 'v$session.program' terhubung ke Oracle?

Kami menemukan jawabannya. Nama aplikasi kami terlalu panjang satu karakter:49 karakter bukannya 48 atau lebih sedikit.

Berikut daftar v$session properti dan batas panjangnya:

• v$session.machine :64
• v$session.iname :tidak ada batas
• v$session.ename :tidak ada batas
• v$session.process :24
• v$session.program :48
• v$session.terminal :30
• v$session.osuer :30

Selain itu, tidak ada properti yang cocok dengan ekspresi reguler ini:.*[\00\(\)].* , yang menurut saya berarti tanpa tanda kurung.

Jika Anda mendapatkan kesalahan dan ingin melihat kodenya, tambahkan saja breakpoint pengecualian di IDE Anda untuk SQLException . Anda harus berakhir di kelas yang disebut T4CConnection.class .

Berikut kode yang didekompilasi untuk metode ini, validateConnectionProperties() :

void validateConnectionProperties() throws SQLException {
    super.validateConnectionProperties();
    String var1 = ".*[\\00\\(\\)].*";
    SQLException var2;
    if(this.thinVsessionOsuser == null || !this.thinVsessionOsuser.matches(var1) && this.thinVsessionOsuser.length() <= 30) {
        if(this.thinVsessionTerminal == null || !this.thinVsessionTerminal.matches(var1) && this.thinVsessionTerminal.length() <= 30) {
            if(this.thinVsessionMachine != null && (this.thinVsessionMachine.matches(var1) || this.thinVsessionMachine.length() > 64)) {
                var2 = DatabaseError.createSqlException((OracleConnection)null, 190, "Property is \'v$session.machine\' and value is \'" + this.thinVsessionMachine + "\'");
                var2.fillInStackTrace();
                throw var2;
