Q: Caching Server - can you delete individual files?

Hi W.Loring,

Try these two suggestions:

- Run under sudo:

/Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin settings caching:LogClientIdentity = true

/Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin stop caching

/Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin start caching

- then check the cache service log in Server.app for clues

- Check :  Configure OS X Server Advanced Cache Settings and adjust LogLevel , restart the cache service and check the alternative log file for clues.  Remember the performance will reduce with such a setting.

hope this helps, dwbrecovery

So no entries for iTunesX.pkg and iTunesAccess.pkg in the Caching Service log in Server.app?

The default is that all the content are stored in /Library/Server/Caching ... it contains three directories, Config , Data , Logs , which have respectively in Config - the Configuration plists; in Data all the downloaded Apps, Books and Updates to programs. In the Logs you will find the actual Logs.

Inside the Data folder, Server maintains a database (AssetInfo.db) for which you have to use SQlite to be able to see what is cached. The individual Commands are:

server:~ xxxxxxx$ sudo sqlite3 /Volumes/SeparateHD/Library/Server/Caching/Data/AssetInfo.db

or

server:~ sssssss$ sudo sqlite3 /Library/Server/Caching/Data/AssetInfo.db 

and validate with your Admin  Password.

(This will start sqlite3 with the 'AssetInfo.db' Database used by your server)

SQLite version 3.8.10.2 2015-05-20 18:17:19 Enter ".help" for usage hints.

Then follows the following commands:

sqlite> .tables

You will see the different Tables listed.

ZAFFINITY ZASSET Z_METADATA Z_MODELCACHE Z_PRIMARYKEY

for the printout to make sense to you:

sqlite> .mode column

sqlite> .headers on

sqlite> select * from ZASSET;

The output will be a table in Terminal which you can inspect to find what is there. The final value would be what you are interested in, before that are the location where it is stored on the disk and where it can be found using Finder.

As you can see, it is not just a simple matter of just erasing or editing something from a log file. It is important not to corrupt this database.

I checked and same issue exists here.  Let you know if resolved.

First, identify the directory where the damaged asset lives by searching through the Debug log files in /Library/Server/Caching/Logs for a message like "Asset /blah/blah/iTunes12.5.1.pkg path /Library/Server/Caching/Data/UUID, extents [0,nnn]".  The UUID is the important part.  Then run "sudo rm /Library/Server/Caching/Data/UUID/0".

Hi MBP, W.Loring

thanks MBP for the info.

- Checked out the Debug logs, found the UUID for iTunesX.pkg, deleted /Library/Server/Caching/Data/UUID and restarted the Caching Service.

- Clicked update for iTunes 12.5.1 on the App Store, noticed the UUID Folder was recreated and the "0" file was downloaded, but unfortunately, same result where the install did not complete on the client.

- It is the same result on Sierra, but there is an error dialog, " An error has occurred "iTunes" could not be verified. (311)

- A developer forum has posts on this error, but as yet no fix.

First time having an issue with the caching service.

Try verifying the integrity of the downloaded file by running "sudo md5 /Library/Server/Caching/Data/UUID/0" and comparing the result against the ZCHECKSUM value for the asset in the database (see Leopardus's comment).

Other things to try:

- Download the iTunesX package yourself using Safari or curl, and then run "sudo cmp /Library/Server/Caching/Data/UUID/0 /path/to/your/download/iTunesX.pkg".

- See if the cached file opens correctly on your server:  "sudo cp /Library/Server/Caching/Data/UUID/0 /tmp/iTunesX.pkg; open /tmp/iTunesX.pkg"

- On the computer where iTunesX fails to install, check the install log files for relevant error messages.

Hi W.Loring,mbp,

- ended up using  Install iTunes.pkg  from Apple Downloads and deployed it using ARD Admin and all clients installed without issue.

- thanks for the further tips mbp, still to investigate.
