TQ MSGID not returned as it was working before

[rlenka1]

1. What versions are you using?

2. Is it an error or a hang or a crash?

3. What error(s) or behavior you are seeing?

4. Does your application call init_oracle_client()?

5. Include a runnable Python script that shows the problem.

a=queue.enqone(con.msgproperties(payload=book))
print(a)

Version 1.0 was returning MSGID but new version 1.1 not returning

Tried with PLSQL it is also returning

[anthony-tuininga]

Can you provide a complete script that demonstrates the problem? And include the PL/SQL script as well? I'm not sure which attribute you are referring to. Thanks!

This is part of 15. Using Oracle Advanced Queuing (AQ), when we enqueue.
If we run below in PLSQL we get the MSGID, same was also happening in the python when we had below in python

Python code***

                       config_dir="C:\\Users\\User\\Documents\\OracleAutonomousDB\\teqodb\\teqodb_extract",

                       wallet_password=p_walletpass)


# In[34]:


print(con)


# In[35]:


book_type = con.gettype("MESSAGE_TYPE")


# In[36]:


queue = con.queue("OBJTYPE_TEQ5", book_type)


# In[37]:


queue.enqoptions.visibility = oracledb.ENQ_IMMEDIATE


# In[38]:


book = book_type.newobject()


# In[39]:


book.SUBJECT = "Hi There1"


# In[40]:


book.TEXT = "I am Python"


# In[44]:


a = queue.enqone(con.msgproperties(payload=book))


# In[42]:


print(a)

*********** now the print just gives "None" , earlier it was returning MSGIDg

Hmm, I don't see any changes between 1.0 and 1.1 that would suggest print(a) would have produced anything except None. I tried with version 1.0 and confirmed that was indeed the case. You can manipulate the object_aq.py sample like I did to verify that fact. Looks to me like you want to do this, though:

msg = con.msgproperties(payload=book)
queue.enqone(msg)
print("msgid:", msg.msgid)

Thanks.

The output now i get from python is

msgid: b'\xe9\x1eo@mQn\xfc\xe0S#\x14\x00\nSi'
msgid: b'\xe9\x1eo@mSn\xfc\xe0S#\x14\x00\nSi'
msgid: b'\xe9\x1eo@mUn\xfc\xe0S#\x14\x00\nSi'
msgid: b'\xe9\x1eo@mWn\xfc\xe0S#\x14\x00\nSi'
msgid: b'\xe9\x1eo@mYn\xfc\xe0S#\x14\x00\nSi'
msgid: b'\xe9\x1eo@m[n\xfc\xe0S#\x14\x00\nSi'

But in DB via PLSQL i get
E91E6F406D526EFCE0532314000A5369
E91E6F406D536EFCE0532314000A5369
E91E6F406D546EFCE0532314000A5369
E91E6F406D556EFCE0532314000A5369
E91E6F406D566EFCE0532314000A5369
E91E6F406D576EFCE0532314000A5369

Something needs to do with conversion maybe if you can help

[anthony-tuininga]

Those look to be the same. You can confirm that by using this code:

msg = con.msgproperties(payload=book)
queue.enqone(msg)
print("msgid:", msg.msgid.hex().upper())

[rlenka1]

Yes, perfect, thanks for your help, i can reconcile easily now
