Get ready for your 2011 development projects.

floyd_delmuroWritten by Floyd Del Muro

Remember the "good old days" when all we had to worry about was a simple "new-century problem" known as Y2K? Many companies rolled up their sleeves, dug in, and handled that project with fixes: rebuilding, recompiling, and re?creating code.

How do you monitor the IFS and temporary storage growth?

tom_huntingtonWritten by Tom Huntington

You know the all-too?familiar cry from your staff: "Where did the disk space go? Who is responsible for consuming the entire disk?" As a good administrator, you rerun the reports from the past weekend, but you can't find the reason. The library disk reports show that the disk space is the same, yet your WRKSYSSTS disk space percentage is at 92 percent. The culprit may be IFS growth or temporary storage consumption.

TechTip: Questions, Answers, and Tips about Reorganize Physical File Member (RGZPFM) PDF Print E-mail

Don't let improperly managed deleted records slow down system performance.

sandra_cabralWritten by Sandra Cabral

When records are deleted or marked for deletion, they may remain as part of the physical file. It is a good practice to run the RGZPFM command to remove deleted records and free up DASD. Removing deleted records can improve performance of programs that read a file sequentially. It can also help reduce the paging of data in from DASD to memory. The recommendation is to run RGZPFM if the number of deleted records exceeds 20 percent of the total number of records in the file.

Searching through IT logs can be boring and tedious. With the swatch (Simple WATCHer) Linux utility, automate actions based on matching logging conditions.

max_hetrickWritten by Max Hetrick

Awhile back, I showed you how to take advantage of setting up a centralized remote logging facility for Linux. Centralized logging gives you one location to head for when trouble arises. Using the Linux tool swatch, let's take logging one step further by automating alerts or actions based on conditions matching regular expressions.

CPF1240/CPF1241: Job ended abnormally/normally.

tom_huntingtonWritten by Tom Huntington

Who hasn't had a "file full" message in QSYSOPR? It's about as common as a cold. But what do you do with the message? Always the same reaction? What about the QSYSOPR job end abnormally and normally messages, CPF1240 and CPF1241? They're nice to know for certain jobs, but for most jobs, you don't care. When a certain job ends, do you want to execute a command, restart the job, notify someone, or do something else?

Tired of manually filling out the audit log?

tom_huntingtonWritten by Tom Huntington

Do you spend time each day filling out logs to prove to auditors that you have looked at a system report? Do you spend time entering details into a spreadsheet about reports you reviewed? Do you file these reports and then have trouble retrieving them?

Partner TechTip: Save-While-Active for Backups Can Be Handy PDF Print E-mail

Automate your backups with save-while-active.

tom_huntingtonWritten by Tom Huntington

Although the save-while-active feature for backups has been around for many years, a lot of customers are afraid to use this parameter in their save commands. They may have heard something bad about the process at a conference, or they may have tried it and it didn't work. I've found the parameter to be very helpful, but you have to understand how best to use it.

TechTip: With SSHFS, Remotely Mount Linux File Systems Across SSH PDF Print E-mail
Tips & Techniques - System Administration
Written by Max Hetrick   
Friday, 13 August 2010 00:00

Working on remote file systems is made simpler with the user-space-defined file system of SSHFS.

max_hetrickWritten by Max Hetrick

Whether you're on a local LAN or in a remote, distant location, chances are you're using SSH to gain remote access to your Linux servers. With SSH access, tools like scp (secure copy) make it possible to transfer files to and from machines but sometimes with a price of repetitive typing of arguments and commands. Other options such as Samba and NFS can be more difficult to configure and use, with firewalls and diverse network configurations in place. With the tool SSHFS, as long as you have SSH access, remote file systems can be mounted locally, where they can be viewed and used with local tools and scripts.
