Pardon the Dust: Transition in Progress

Things might look a little different on the blog if you haven’t been back in a while.  And, things might not be working quite up to par for a bit.  Please pardon the dust.  I’m trying to get things back in order as quickly as my schedule allows.

So, here’s what’s going on: I am moving my website to a VPS.  My term at Hostgator expired, and I decided that this next year, I want to include SSL on my site and take it to the next level.  Doing so at Hostgator was not cost effective in the least.

So, I am rebuilding everything on my own VPS.  It’s exciting but things may be a bit rough for a few weeks.  I hoping to pull together a new theme on the blog, SSL for securit/SEO, and tie it all together on a multi-site WordPress installation.

Please keep checking back and see how it goes!

Pinging and Posting from PeopleCode

I had a need to Ping a server to see if the server could get to it.  I also tried to post to it.  This code could be helpful for others, so I want to share it.  A post should normally go through the Integration Broker, but I first developed it at a time when I had a product that was supposed to go on servers with diverse versions of Integration Broker.

The Ping code doesn’t seem very reliable for some reason.  Something on the Java side doesn’t always work.  Still it might be helpful.

   Local JavaObject &url;
   Local JavaObject &conn;
   Local JavaObject &r;
   Local any &line;
   Local string &output;
   Local JavaObject &inet;
   Local string &address;

   MessageBox(0, "", 0, 0, "hostname: " | GetJavaClass("java.net.InetAddress").getLocalHost().getHostName());

   &address = "localhost";
   &inet = GetJavaClass("java.net.InetAddress").getByName(&address);
   MessageBox(0, "", 0, 0, &address | "(" | &inet.getHostAddress() | ") reachable: " | &inet.isReachable(5000));
   &address = "www.google.com";
   &inet = GetJavaClass("java.net.InetAddress").getByName(&address);
   MessageBox(0, "", 0, 0, &address | "(" | &inet.getHostAddress() | ") reachable: " | &inet.isReachable(5000));

   &url = CreateJavaObject("java.net.URL", "http://www.google.com");
   &conn = &url.openConnection();
   &conn.setRequestProperty("content-type", "application/x-www-form-urlencoded");
   &conn.setRequestProperty("accept", "text/xml/html");
   &conn.setRequestProperty("accept-charset", "utf-8, iso_8859-1");
   &conn.setRequestProperty("userid", "????");
   &conn.setRequestProperty("pwd", "?????");
   &conn.setDoOutput( True);

   &output = "";
   &r = CreateJavaObject("java.io.BufferedReader", CreateJavaObject("java.io.InputStreamReader", &conn.getInputStream()));
   &line = &r.readLine();
   While &line <> Null
      &output = &output | Char(10) | Char(13) | &output;
      &line = &r.readLine();
   End-While;
   &r.close();

   MessageBox(0, "", 0, 0, &output);

Please make sure to adjust the URLs and hostnames to what you need.

Searching with USEEDIT

Because many of the record properties are hidden in the Bit Map field USEEDIT, it is hard to search for properties.  If you are on Oracle, here’s some SQL that might help…

This SQL lists all of the fields with their properties broken out of that field:

SELECT FIELDNAME,
       USEEDIT,
       Bitand(USEEDIT, 1)         KEY,
       Bitand(USEEDIT, 2)         DUP_KEY,
       Bitand(USEEDIT, 4)         SYS_MAINT,
       Bitand(USEEDIT, 8)         AUDIT_ADD,
       Bitand(USEEDIT, 16)        ALT_SEARCH_KEY,
       Bitand(USEEDIT, 32)        LIST_BOX_ITEM,
       Bitand(USEEDIT, 64)        ASCENDING_KEY,
       Bitand(USEEDIT, 128)       AUDIT_CHANGE,
       Bitand(USEEDIT, 256)       REQUIRED,
       Bitand(USEEDIT, 512)       XLAT,
       Bitand(USEEDIT, 1024)      AUDIT_DEL,
       Bitand(USEEDIT, 2048)      SEARCH_KEY,
       Bitand(USEEDIT, 4096)      EDIT_REASONABLE_DATE,
       Bitand(USEEDIT, 8192)      EDIT_YES_NO,
       Bitand(USEEDIT, 16384)     EDIT_PROMPT_TABLE,
       Bitand(USEEDIT, 32768)     AUTO_UPDATE,
       Bitand(USEEDIT, 65536)     BIT65536,
       Bitand(USEEDIT, 131072)    BIT131072,
       Bitand(USEEDIT, 262144)    FROM_SEARCH,
       Bitand(USEEDIT, 524288)    TO_SEARCH,
       Bitand(USEEDIT, 1048576)   EDIT_BINARY,
       Bitand(USEEDIT, 2097152)   DISABLE_ADV_SEARCH,
       Bitand(USEEDIT, 4194304)   REGULAR_FIELD,
       Bitand(USEEDIT, 8388608)   DEFAULT_SEARCH_FIELD,
       Bitand(USEEDIT, 16777216)  BIT16777216,

Search for a Field with Translates

I was looking for an “Internal/External” field.  I wanted a field already built that had two translate values: “E” and “I”.  This SQL did the trick:

SELECT A.FIELDNAME,
A.XLATLONGNAME,
B.XLATLONGNAME,
A.XLATSHORTNAME,
B.XLATSHORTNAME
FROM   PSXLATITEM A,
PSXLATITEM B
WHERE  A.FIELDNAME = B.FIELDNAME
AND A.FIELDVALUE = 'E'
AND B.FIELDVALUE = 'I'
AND Upper(A.XLATLONGNAME) LIKE 'EXT%'
AND NOT EXISTS (SELECT 'X'
FROM   PSXLATITEM C
WHERE  A.FIELDNAME = C.FIELDNAME
AND C.FIELDVALUE NOT IN ( 'E', 'I' )) 

I found the INTERNAL_EXTERNAL field, which works just perfect for me.

Anyone need remote help?

Does anyone know of any good contracts that would support mostly remote work?

I started this blog years ago with the idea that it would be a good place to search for work should I ever need it. I think the time has come to just ask to see if projects are available through this avenue. If you know of anything, I would love to speak with you. Would you mind commenting below or sending me a “Linked In” message?

New PeopleCode Dump Method

One of my old tricks was to create a PeopleCode dump from the system.  Then I could use a text editor tool such as gVim or Ultraedit to search through the code to find examples or certain uses of definitions.

Basically, a PeopleCode dump is easily created by searching for (Edit > Find In) a semicolon.  Because every statement must have a semicolon, it matches every statement of code in the system.  On the Find In dialog, checking the Save to File option will write out each line to a text file.

The problem is that Application Designer seems to load every line into memory.  If you don’t have a client machine with a ton of memory, you end up looking like this:

App Designer Out of Memory Error

 

Instead, I found this new tool called Decode PeopleCode.  You can download the latest zipped version of the program from here.

Once extracted, I had to configured the URL property in the DecodePC.properties file.  I set it to something like this:

url=jdbc:oracle:thin:@<server name>:1521/<db name>

I also had a problem with the JDBC driver for some reason.  It didn’t find the odbc5.jar file that was delivered.  I already had a copy of the odbc6.jar, so I just adjusted the classpath to include that.  If you run into the same problem, adjust the DecodePCODE.sh or DecodePCODE.bat file to contain the full path to the jar file.

Also, adjust the “outdir” property in the DecodePC.properties file to point to the directory where you want the output dumped.  Note that it will create a bunch of folders and files in that directory, so you may want to point it to an empty directory.

Then, I ran the program with this command to capture everything:

sh DecodePCODE.sh since 1901/01/01

Now, that creates each PeopleCode program in its own file.  The problem is that I want it all in a single file that I can run regular expressions against.  I could use grep, but I am used to a single file.  I cobbled this script together to build that single file:

#!/bin/bash


processFile() {
   outdirlen=$((${#OUTDIR} + 1))
   filename=$1
   lastUpdateFile=$( echo "$filename" | sed 's/\.pcode$/.last_update/' )
   peoplecodePath=${filename:$outdirlen}
   peoplecodePath=$( echo "$peoplecodePath" | sed 's/\//: /' | sed 's/\.pcode$//' | sed 's/\//./g')
   echo -e "\e[0K\r Writing: $peoplecodePath"
   echo "[$peoplecodePath]" >> "$OUTFILE"
   echo '/*   Details:' >> "$OUTFILE"
   echo '   Last Update User: ' $(head -n 1 "$lastUpdateFile") >> "$OUTFILE"
   echo '   Last Update Date/Time: ' $(tail -n 1 "$lastUpdateFile") >> "$OUTFILE"
   echo '*/' >> "$OUTFILE"
   cat "$filename" >> "$OUTFILE"
}


#  ------------------------------
#    Main
#  ------------------------------

OUTDIR=$( grep "outdir=" DecodePC.properties | sed 's/^outdir=//' | sed 's/\r//')
DUMPDATE=$(stat -c %y $(ls -rt | tail -n 1) | cut -d ' ' -f1 )
DATABASE=$( grep "^url=" DecodePC.properties | sed 's/^url=.*\///' | sed 's/\r//')
OUTFILE="$OUTDIR/all.pcode"
echo "outdir -- $OUTDIR  dump date -- $DUMPDATE  database -- $DATABASE"

echo "PeopleCode Dump $DATABASE   $DUMPDATE" > "$OUTFILE"
find "$OUTDIR" -type f -name \*.pcode | while read file; do processFile "$file"; done

That seemed to get the trick done for me nicely.

This program has more features than just this. You should explore it. It can check the code into a sourcecode repository to track changes. Kudos to whoever wrote it!
