Sometimes you just HAVE to edit a source member, but the machine does not have SEU installed, nor is Operations Navigator available. It happened to me today, and I was desperate.
WAIT! Isn't every, virtually every file on the 400 part of the DB2 database? Sure enough, you can use interactive SQL to update source member records.
1. Make a copy of the member first just in case you mess something up:
CPYF FROMFILE(APP43/QSQLSRC) TOFILE(APP43/QSQLSRC) FROMMBR(L43S2)
2. Choose the source member you want to update by overriding the file:
OVRDBF FILE(QSQLSRC) TOFILE(APP43/QSQLSRC) MBR(L43S2)
3. Determine the source statement that you want to modify using SQL to display the member and note its SRCSEQ number:
SELECT * FROM QSQLSRC
3. Make sure you have the right record number before you try to make the change:
SELECT * FROM QSQLSRC WHERE SRCSEQ=0046.00
4. Then do the update:
UPDATE QSQLSRC SET SRCDTA='CREATE INDEX XAK1PROP_HDR ON PROP_HDR'
5. Exit SQL and use Display Physical file Member to be sure the change was what you wanted:
DSPPFM FILE(APP43/QSQLSRC) MBR(L43S2)
It would be very tedious to make more than a few changes this way, but when you really need, and 5769-ST1 is installed, it can save your day!
- Sounds good to edit source member using SQL, but an easier way would be to use DBU (of course, if you have DBU utility) Eg. DBU &lib/@srcfile then select the &MBR you want to edit and using the CHANGE mode, you can modify the code, For a more broader view, do a "F21" on your DBU and edit however you want. You don't have to worry about remembering anything here (srcseq, srcdata etc.). —Johnson Rodrigues
