A Pinoy DBA's Blog
WELCOME!
What is Pinoy? It's a slang for Filipino, a person who comes from the Republic of the Philippines, or commonly known as the Philippine Islands (PI). I am a Filipino and works as an Oracle DBA in the United States. Whenever an issue arises or just for experiments, I usually forget what I did to solve/conduct them. There must be a central location where I can put everything. Thus, this blog was born. It's a collection of ideas, tips and tricks, scripts, or anything interesting that happened to me on an Oracle database or any other stuff.
The simpler, the better! has always been my motto. You don't have to complicate things. Simple things, for me, is always easier, just like my site.
FYI, anything that is written here is based on my personal experiences and is not endorsed by any other party. Also, I will not be held liable for issues that can arise by following whatever I did. Just like any other good DBA would say... ALWAYS TEST!
Hope you can find this site helpful in whatever you need and remember, I am not a guru.Feb 27, 2020
Deleted photos showing on iPhone 11 Pro
I tapped the Photos App -> photos -> Year. Then, I went and deleted photos for each month/day by tapping on select all then tapping on the trash been. I did this for each day from 2017 until end of 2018. After a painstaking hour or so, I was able to delete everything she wanted, even clearing the Recently Deleted folder. So, I gave back her phone.
But she handed it back to me saying that the photos are still there. So, I checked by tapping the Photos App -> photos -> All Photos. And indeed, the photos are still there. Something might be wrong! Is it a bug? So, I went and chat with a support representative.
After giving all the requested information, she said that I also need to delete the photos in the "All Photos" album. I asked her why. She said "because it is a different album". Wow! I just can't believe what she said. She continued by saying it was by design.
So, the reason why your new iPhone storage isn't freeing up even after deleting so many pictures, and clearing the Recently Deleted album is because your photos are being duplicated so they can show up in different albums. What a waste of storage space!!! I cannot believe that this is how they designed this thing. IT IS REALLY A WASTE OF STORAGE SPACE!!! I think my respect for the Apple Engineers went down.
Oh, well, the only way to free-up space is go into the different albums and start deleting photos.

SOLR data/index Directory Growing
Usually, SOLR segments are in a directory named index but ours doesn't show any. All of them was named index.YYYY*. So, I checked the index.properties file to determine which index directory SOLR is using, then deleted the others.
However, this didn't solve the issue. Our data directory is still huge. Further investigation showed that there are old segments in the data/index directory. I restarted the slaves but it didn't help.
After comparing files, etc., I noticed that the difference between the slaves that has the correct size and those that don't, is the timestamp of the write.lock file. I deleted the write.lock file and forced a DIH process. After the slaves replicated, the old segments are gone. Just a note, there should be at least one document updated on the master for this to work.
HTH.

"HttpSolrServer$RemoteSolrException: We are not the leader" Solr Cloud
I added the replica back. Waited for it to recover but unfortunately, it didn't and there were error messages in the log file:
Error while trying to recover. core=coreName:java.util.concurrent.ExecutionException: org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: We are not the leader

I tried to delete and add the said replica but got the same error.
The solution is to restart the SOLR instance that was on the leader node of the collection where the replica was deleted. This will reset the leader for that collection and eventually have M01 recover.
Hope this helps

Vonage 3000 to Globe Philippines
Now, what's wrong with this? Nothing. Now people that's interested would know that you are only allowed 3000 minutes per month. Any subsequent usage after 3000 minutes will be additional.
People will say that Vonage is not clear. Well, I would say I haven't encountered this problem yet. Everytime we call the Philippines, we can clearly hear them.
Now, I am okay with the Vonage 3000 to Globe Philippines. At least, I am not expecting to have my subscription unlimited.
