Madison,
It's a test system - we will rebuild. Thanks

OK - I've opened a bug for this problem - 172306. There's no need to open a case for this. I've tested a patch and we'll be including in the build after tomorrow's code review.

I got an email about this statement. There was a bit of concern that the code would go into the product with no QA. I thought that would be a chance to describe what the integration process is for ER (and MACH11/CDC).

1) The engineer develops a patch and performs unit testing to verify that the patch is working.

2) We have a daily code review which is attended by the members of the HA team. In the code review each of the engineers is allowed to raise any issues that they want. Depending on what the patch is, we may require that additional testing is performed.

3) After the code review, the patch is merged into a staging branch used by ER/MACH11). The staging branch is built nightly and goes through some 10 hours of automated testing daily. There is a daily reverse merge from the main release branch to the staging branch so that all patches from other teams are merged into the staging branch.

4) After the code has been in the staging branch for several days, it is merged into the main release branch where it goes through a different set of testing. Since the patch is also contained in the staging branch, that means that the patch is still going through our testing.

5) Only after the patch has received extensive testing in the main release branch is it released to the customer in the form of a pid drop.

The SQLHosts file has the uppercase entry in it for both the instance name and the group name (g_Stan2 and server is Stan2).
There is no lower case name anywhere.
As I said, I know it isn't good practice - just wondering if I should raise it with support?

Yes, but the bug is not what you think. The documentation states that
the DBSERVER field in the sqlhosts is not supposed to contain upper case
letters. (page 3-17) So the real issue is that the cdr utility didn't
catch that you used an uppercase letter when defining the server.

If this is a test system, then you'll need to rebuild with the correction to the group name. If this is a production system, then you

will need to open a case with tech support and have them contact me. I guess you can contact me directly, but we still need a tech support
case to open the bug.

Hi,
We are looking at 11.50.UC3 for an upgrade to ER and came across a funny bit.
First - both servers are RHEL4 running 11.50.UC3.
One is called sirrp61 and the other Stan2 - note the capital letter
in
the start of the name.
ER is established between the pair fine and replicates created. When I go to sync a replicate it fails with the below - and it has used a lower case version of the group number g_stan2 in the attempt to connect message.
Now I know it isn't a good idea to let capital letters and Linux mix,

but worth noting.
What is in the sqlhosts file? The output of list server is from the
syscdr database. Do the names match?

Can you let me know if I am missing something here? otherwise I will look to raise a PMR as a bug.
Thank
