Let’s start out with what’s actually available in the Server Admin CLI: serveradmin. The serveradmin command, followed by settings, followed by san shows a few pieces of information: /Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin settings san The results would be similar to: san:computers = _empty_array san:primaryController = "95C99FB1-80F2-5016-B9C3-BE3916E6E5DC" san:ownerEmail = "krypted@me.com" san:sanName = "krypted" san:desiredSearchPolicy:_array_index:0 = "" san:serialNumbers = _empty_array san:dsType = 0 san:ownerName = "Charles Edge" san:managePrivateNetwork = yes san:metadataNetwork = "10.0.0.0/24" san:numberOfFibreChannelPorts = 2 san:role = "CONTROLLER" Here, we see the metadata network, the GUID of the primary (active) MDC, the name of the SAN, an array of serial numbers (if applicable – rarely encountered these days), the owner info plugged in earlier…

Moar About SQL Wildcards
Previously we looked at using wildcards in conjunction with the SQL LIKE operator. Wildcards allow you to search for data in a defined table. Think of them as text globbing for SQL. The wildcards available include the following: [list]: Define a ranges of characters for pattern matching [!charlist]: Matches only a character NOT specified within the brackets %: Require a single character/object in a pattern _: Allow any single character in a pattern In this article, we’ll use the same “Customers” table from our first articles: ID Site Contact Address City Zip Country 1 Krypted Charles Edge my house Minneapolis 55418 US 2 Apple Tim Cook spaceship Cupertino 95014 US 3 Microsoft Satya Nadella…

Some Command Line java Debugging Options
There’s an excellent tool that can be used to grab a heap dump from a Java process. It’s called jmap. To do so, run the jmap command, followed by a format and a file path as the format and file operators. Also, provide the PID, as follows: jmap -dump:format=b,file=~/memdump.hprof 80446 Once dumped, you can view the dump file in the Memory Analyzer Tool (MAP) and find objects that use use too much memory and/or have memory leaks, as part of your troubleshooting. You can also replace the pid with a name of an executable or a core. Run the map tool along with a -h option for a help summary.…

Simple Preflight and Sanity Checking in Scripts
I was recently building some preflight scripts and was looking to record some information about a machine live, before proceeding with a script. I found the cheapest way to determine information about architectures and chipsets when scripting preflight scripts for OS X to be the arch and machine commands respectively. For example, to verify the architecture is i386, use the arch command with no options: /usr/bin/arch Which simply outputs “i386”: i386 To check the machine type, simply use the machine command: /usr/bin/machine Which outputs as follows: x86_64h

iPhone and GroupWise
There is no built-in support for GroupWise on the iPhone. Apple supports a number of other services, but GroupWise has not been high on the priority list and honestly, I don’t know that it would be high on mine either… Having said that, it did pop up on my radar and I was able to find a couple of ways to achieve a good sync. The first is Entourage. You can use Entourage as a conduit to then grab information and sync it with GroupWise. This has a hopefully obvious disadvantage, which is that it does not synchronize wirelessly – you have to cradle sync to get the data onto…
