Informix Error Messages and Error Codes From Error 527 to 530

SQLServerF1

Informix Error Code -527 Lock Mode is not available on this system.
You tried to use the SET LOCK MODE TO WAIT statement on INFORMIX-SE, but your INFORMIX-SE database server uses CREATE LOCKING rather than System V locking. If the error recurs, please note all circumstances and contact Informix Technical Support.
The database server cannot execute the SET LOCK MODE TO WAIT statement because the host operating system does not have adequate support for locking to permit waiting for a lock to be released. On this system, your program will be notified when a table or row is locked (with an error such as -233 or -378); your program determines what to do next, such as rolling back the transaction and trying it again.

Informix Error Code -528 Maximum output rowsize max-size exceeded.
The total number of bytes that this statement selects exceeds the maximum that can be passed between the database server and the program. Make sure that the columns selected are the ones that you intended. Check that you have not named some very wide character column by mistake, neglected to specify a substring, or specified too long a substring. If the selection is what you require, rewrite this SELECT statement into two or more statements, each of which selects only some of the fields. If it is a join of several tables, you might best select all desired data INTO TEMP; then select individual columns of the temporary table. If this is a fetch via a cursor in a program, you might revise the program as follows. First, change the cursor to select only the ROWID of the desired row. Second, augment the FETCH statement with a series of SELECT statements, each of which selects one or a few columns WHERE ROWID = the saved row ID.

Informix Error Code -529 Cannot attach to shared memory.
This error message appears prior to Version 6.0. Your application program is unable to initialize its connection to the database server because you are using a shared-memory implementation. Either the database shared memory has not been initialized, or the maximum number of users has already started using the system. Check the accompanying ISAM error code for more information.
Informix Error Code -529 Cannot attach to transaction.
This error message appears beginning with Version 6.0. Your application program is unable to initialize its connection to the database server because you are using a shared-memory implementation. Either the database shared memory has not been initialized, or the maximum number of users has already started using the system. Check the accompanying ISAM error code for more information.
Informix Error Code -530 Check constraint constraint-name failed.
The check constraint placed on the table column(s) was violated. To see the check constraint associated with the column(s), query the syschecks system catalog table. However, you must know the constrid for the check constraint before you query syschecks. (The constrid is assigned in the sysconstraints system catalog table.) Use the following subquery to show the check constraint for constraint-name:SELECT * FROM syschecksWHERE constrid = (SELECT constrid FROM sysconstraints WHERE constrname = constraint-name)

Above are list of Informix Error Messages and Errors Codes or Status Codes or Exit Codes along with Error and Warning messages received while performing certain operation against Informix applications or related products.

What are Informix Error Messages?
All Informix messages returned by the Informix server are assigned an error code.

In general, each Informix error contains the following information:
• The Informix Error Code or Informix Error status
• The message text. This text is usually returned with the Error code. Some messages employ word substitution, where the word substituted represents the system-replacement of a term more specific to the occurrence.
• An explanation of how the error may have occurred.

Hope this was helpful.
