I started seeing this today in one of our databases I found metalink article 2360045.1 which states that it is a catalog version mismatch, however running upgrade catalog doesn’t resolve the problem. I remember hitting this error a long time ago, and although I can’f find the reason why, running upgrade catalog two times in …

TDE Wallet on RAC
So I have been having trouble getting the oracle wallet to auto open, and it’s always messed up in gv$encryption_wallet

select * from gv$encryption_wallet; INST_ID WRL_TYPE WRL_PARAMETER STATUS WALLET_TYPE WALLET_OR FULLY_BAC CON_ID ---------- ------------ ---------------------- ------------- ---------- ------------ ------ 4 FILE OPEN AUTOLOGIN SINGLE NO 0 1 FILE OPEN AUTOLOGIN SINGLE NO 0 3 FILE NOT_AVAILABLE UNKNOWN SINGLE UNDEFINED 0 2 FILE NOT_AVAILABLE UNKNOWN SINGLE UNDEFINED 0 |
According to Oracle this is is because TNS_ADMIN is not set, so I set it and several other suggested variables.

After restarting the database, the ACFS volume now shows

Its computing tablespace size. The average runtime is 272.03 sec, or 4.5 minutes. This isn’t right, its running in a few seconds in other databases. I started looking at the query in OEM, and noticed almost all the execution time was …

Monitoring Online ASM Datafile Moves
I’m moving a ~7TB database online as the development group that uses it doesn’t want to take any down time. Thankfully the database isn’t horribly active right now so moving the data files online isn’t causing a huge problem. The only other times I have moved data files online was in an incredibly busy database …

Now on SSL
I have moved this site over to a secure connection. LetsEncrypt offers free SSL certificates for your website! The setup was a bit of a pain because I have a non-standard configuration for this server, but after a little poking and prodding, we are now running on https.

Rushing = Stupid Mistakes
I am currently being asked to refresh a database. The end users are pissed because they asked for the database to be refreshed at noon yesterday, this was the first they had asked for it, and they were doing “really important things” and by 3pm were pissed that I hadn’t responded to them, let alone …

Why Didn’t Oracle Export That?
Ever wonder where Oracle keeps track of objects that won’t be exported?

select * from sys.ku_noexp_tab; |
This table contains a list of objects that will be ignored during an export.

Unzipping all Zip files in a directory
I don’t know why zip can’t handle multiple inputs, but it cant’. Gzip does just fine unzipping everything in a directory, I use this little “script” all the time on the command line to unzip all the files in a directory.

for file in $(ls *.zip) do echo $file unzip -o $file done |
Its a small simple script, but it’s useful.
